               Goodbye to Victoria
       Victoria was waving goodbye.
       She looked very small on the TARDIS’s monitor screen,
lost and alone on the wide stretch of empty beach.
       Two very different figures stood gazing sadly at the
monitor screen. One was that wandering Time Lord known as
the Doctor, a rather shabby little figure in frock coat and
baggy check trousers. His deeply lined face, which could look
young or old, wise or foolish, was crowned with a mop of
untidy black hair. Beside him stood a brawny young man in
the kilt of a Scottish Highlander. This was James Robert
McCrimmon - Jamie for short. Like Victoria, Jamie had been
the Doctor’s companion through a number of dangerous and
terrifying adventures.
       Now Victoria was leaving them and Jamie was taking it
hard. Somehow it didn’t make things any better that Victoria
was leaving them of her own accord. She had had all the
adventure and excitement she could take and she had
decided to stay behind on Earth with a family who would be
glad to adopt her as their daughter.
       Somehow Jamie just couldn’t accept it. ‘We can’t just -
leave her, Doctor.’
       ‘We’re not leaving her, Jamie. It was her decision to
stay,’ the Doctor said reassuringly. ‘She’ll be happy with the
Harrises, don’t worry.’ .
       Jamie hated showing his feelings. ‘I’m no’ worrying, I’m
just - och, get us away from here, will ye?’
       ‘All right,’ said the Doctor obligingly. He moved over to
the many-sided central control column. ‘Where would you
like to go?’
       Theoretically, all space and time were available to them.
       Theoretically.
       In practice, as Jamie well knew, the combination of the
TARDIS’s erratic navigational circuitry and the Doctor’s even
more erratic steering, meant they were liable to fetch up
almost anywhere - and anywhen, come to that.
       But for once this suited Jamie fine. ‘I couldna care less!’
The Doctor gave him a sympathetic look. ‘I was fond of her
too, you know, Jamie.’
       His hands moved over the controls and moments later
the central column of the control panel began its rise and fall.
The TARDIS was about to take off.

      On the beach, the incongruous square blue shape of the
police box gave out a strange wheezing, groaning sound and
faded slowly away.
      Victoria looked on sadly, her eyes filling with tears...

     On the monitor screen her figure grew even smaller,
receding into the distance.
     The Doctor switched off the monitor and turned away.

     It was some time later before the rising and falling of the
centre column began slowing down.
     The Doctor looked up from the controls. ‘We’re
landing, Jamie!’
     There was no reply.
       The Doctor turned and saw Jamie fast asleep in his
chair. Like the good fighting man he was, Jamie took every
opportunity for a nap.
       ‘Jamie! We’re landing!’
       Jamie blinked. ‘Mmm? What?’
       ‘Let’s see what’s on the scanner shall we?’
       The Doctor switched on the screen, but it remained
blank. He frowned and jiggled the switch.
       Still nothing.
       ‘I thought you said we’d landed,’ said Jamie grumpily.
       ‘We have - but we seem to have lost the picture.’ The
Doctor flicked another switch. ‘Let’s try a bit of extra power,
shall we?’
       Nothing happened.
       ‘You’re sure you’re using the right one?’ asked Jamie
sceptically.
       The Doctor was indignant. ‘Of course I am! Just take a
look at the fault indicator, will you? Just there to your right.’
       Jamie opened the lid of a small black box built into the
console. Inside he saw an oscillation meter, its glowing lines
pulsing in a regular pattern. It meant absolutely nothing to
him. ‘Seems right enough,’ he said hopefully.
       The Doctor glanced at the meter. ‘Yes, no abnormal
movement at all. I don’t understand it.’ He checked the other
dials. ‘Air normal, temperature normal... seems to be quite an
amount of metal all around us...’
       ‘What’s that, Doctor? I canna hear ye when you mumble
to yourself.’
       Suddenly the Doctor caught sight of the monitor screen.
‘Look, the picture’s coming through again.’
        There on the monitor was a beautiful lake and as they
watched a flock of cranes rose lazily from its surface and flew
gracefully away.
        Jamie cheered up. ‘Och, that looks all right.’
        The picture changed and now they were looking at a
waterfall, its cascading waters gleaming in the moonlight.,
        The Doctor frowned. ‘That’s funny, it’s changed to night
now.’
        ‘That’s a wee bit quick, surely?’ muttered Jamie. The
picture changed again. Now they saw a tropical island, white
sands, waving palms, all set in a bright blue sea.
        ‘Och, now the whole place is different. What’s going on?’
        ‘Oh dear, I know what it is,’ said the Doctor suddenly.
‘Those pictures aren’t of the outside world at all, I’m certain
of it!’
        ‘Then why are they appearing?’
        ‘Temptations, Jamie. The TARDIS is telling us to leave
wherever we are and go to somewhere more pleasant. I must
have connected the automatic defence network by mistake.’
        ‘And what’s that?’
        ‘One of the optional extras built into this particular
model. I don’t often use it; it’s a perfect nuisance to be
honest.’
        ‘What does it do?’
        ‘Well, if there’s danger outside it tries to warn us - or as
in this case, to tempt us - into going somewhere else.’
        ‘That’s guid enough,’ said Jamie. ‘Let’s go!’
        The Doctor sighed. ‘Jamie, if I took any notice of that
silly gadget, we’d never even leave the TARDIS. It’s so fussy.
That’s why I usually disconnect it.’
        ‘No wonder we always end up in trouble!’
       The Doctor was struggling with the switch that would
turn the automatic defence network off, but it refused to
budge. ‘Oh dear, now I can’t seem to move it. Where’s my
spanner...?’
       Jamie glanced casually at the fault indicator - its lid was
still open - and his eyes widened. ‘Hey! There’s a light
flashing...’ The Doctor looked. Sure enough an alarm-light
was flashing wildly, and the lines on the oscillation meter were
pulsing furiously. ‘Something’s gone wrong,’ said Jamie
worriedly.
       The Doctor wrinkled his nose and sniffed. Tracing the
acrid reek to its source, he saw wisps of smoke coming from
the control console. ‘There’s too much power...’ He rushed to
the main power switch and tried to thrust it back. It refused to
budge, and Jamie came to help him. Suddenly there was a
bang and a flash and a cloud of smoke and the Doctor and
Jamie were hurled across the control room. They struggled to
their feet. By now it was obvious that something was badly
wrong.
       The central column was rising and falling rapidly, and
lights were blinking on and off all over the console. The
TARDIS’s usually inaudible electronic hum had turned into a
steadily rising shriek.
       ‘The fluid links must have gone,’ muttered the Doctor.
       Jamie pointed to the base of the central column. ‘Look,
Doctor!’
       The Doctor saw a silvery fluid leaking from the base of
the column. ‘The mercury’s vaporising!’ As if to confirm his
theory, Jamie coughed and clutched at his throat. ‘Doctor!’ he
gasped.
      Now they really were in trouble, thought the Doctor.
Mercury vapour was a deadly poison. ‘We’ve got to get out of
here.’
      ‘How?’ croaked Jamie.
      The Doctor took his arm and led him to the TARDIS
doors. He touched a concealed button and a little panel slid
back in the wall. Behind it, clamped to the wall, was a golden
rod, black at either end.
      ‘Hold on to me, Jamie,’ ordered the Doctor. ‘What are
you going to do?’
      ‘Just hold on!’
      Jamie enfolded the Doctor in a kind of awkward bear-
hug, and the Doctor reached out and pulled the gold rod
away from its fitting.
      Jamie heard a sound like a rushing wind and the control
room seemed to swirl around him. It began pulsing in and
out of existence, more and more rapidly, and suddenly
everything was extinguished in a blaze of light. The last thing
Jamie heard was the anguished electronic howling of the
console...

      Jamie opened his eyes.
      He was still clutching the Doctor and they were jammed
together in some kind of enclosed space, somewhere small
and square. The Doctor struggled free and Jamie followed
him.
      To his astonishment, he found himself standing outside
the TARDIS. The outside was the familiar square blue shape,
but glancing behind him, Jamie saw that the inside was totally
different. There was no sign of the impossibly large control
room - instead there was just the amount of space you’d
expect to see inside. ‘Doctor, what have you done? You’ve
shrunk the TARDIS!’
       The Doctor held up the golden rod. ‘I disconnected the
Time Vector Generator.’
       What does that do?’
       ‘It controls the size of the interior of the TARDIS
amongst other things. Once it’s removed, the interior
becomes an ordinary police box once again.’
       Jamie looked stunned.
       The Doctor closed the TARDIS doors. ‘Come and sit
over here, Jamie.’
       For the first time, Jamie became aware of his
surroundings. He was in a kind of metal cave, surrounded by
massive metallic shapes. ‘Where are we?’
       ‘Oddly enough, we seem to be in the motor section of
some sort of rocket.’
       The Doctor led Jamie to a kind of ledge surrounding
one of the vast pieces of machinery and sat him down. He
himself wandered over to an instrument panel set into the
wall. A row of dials was labelled ‘Gravity Field Strength’.
       The Doctor studied the readings. ‘Yes, there’s an
artificial gravity system on the ship...’
       ‘And what’s that?’
       ‘Gravity, Jamie. We shouldn’t be able to stand up
otherwise, we’d be floating about.’
       ‘Oh aye?’ Jamie licked his lips. ‘There’s no water around
anywhere, is there?’
       The Doctor looked round. ‘Not in here, no.’ He paused.
‘There doesn’t appear to be any movement either.’
       ‘We’re on the ground then?’
       ‘I don’t know, Jamie. Perhaps. Aha!’
       The Doctor was fishing in his pockets.
       ‘Well come on, don’t keep me in suspense,’ grumbled
Jamie.
       The Doctor fished out a crumpled paper bag. ‘Have a
sherbet, it’ll help to quench your thirst!’ The Doctor gave
Jamie a sweet, took one himself and began a renewed study of
their surroundings.
       There was a metal door at the far end of the motor area,
and the Doctor bent down and studied the floor just in front
of it. Twin track marks led directly to the door.
       Jamie rose and came to join him. ‘That warning system
of yours must have thought there was something wrong out
here. But what can the danger be? Everything’s so - dead in
here.’
       The Doctor indicated the tracks. ‘Something’s been
here, Jamie.’ He bent down and rubbed a finger across one of
the track marks, and then sniffed it. ‘Oil. It must have been a
machine of some kind. In here fairly recently too...’
       Jamie wandered up to the door and saw a button set
into the wall just beside it. Impulsively he pressed it and the
door slid smoothly open.
       Jamie jumped back in alarm. ‘Sorry, Doctor!’
       But the door revealed nothing more alarming than a
short section of metal corridor with yet another door at the
other end. The Doctor and Jamie moved cautiously into the
corridor. The Doctor noticed that the tracks led along the
corridor and up to the door ahead of them. Set into the wall
at the left of the door was a bank of monitor screens with a
control panel beneath them. On the right they could see the
outline of two closed hatches set into the corridor wall.
       The Doctor crept cautiously up to the next door and put
his ear to it.
       ‘Doctor -’ began Jamie.
    The Doctor waved him to silence. ‘Ssh, Jamie! We don’t
know what may be on the other side...’
                        2
                The Unseen Enemy
       The Doctor paused for a moment, thinking hard. They
couldn’t just stay where they were - they’d starve apart from
anything else - but he was reluctant to move ahead without
knowing what might be waiting...
       He turned and studied the bank of monitors, and began
fiddling with the controls. ‘This one? No, should be this one
by rights.’ One of the screens lit up.
       The Doctor and Jamie studied it. There on the screen
was what was obviously some kind of control room - computer
banks, control consoles, a central cockpit area with chairs for
the crew.
       The whole place was silent - and completely empty.
Low-level maintenance lights glowed dimly here and there,
but the recesses of the control room were lost in shadowy
gloom. In the centre of the floor was a strangely sinister
oblong shape. It looked like a metal coffin. Just to one side of
it stood a big crate, also made of some metallic substance.
       Jamie peered uneasily at the screen. ‘Well, it looks safe
enough...’
       ‘But what caused the defense mechanism of the TARDIS
to signal danger? And why isn’t there anyone on board?’ The
Doctor studied a dial set beside the control console. ‘Well,
there seems to be plenty of air in there. Let’s take a look.’ The
Doctor pressed what should have been the door opening
control. Nothing happened. He tried a number of other
controls. They didn’t work either. The Doctor glared
indignantly at the door, trying to work out what to do next.
      ‘I’ll have a nose about back here,’ said Jamie tactfully.
He turned and wandered back to the two hatchway doors set
in the wall. There was something set into each door that
looked very like a handle. Curious as ever, Jamie turned it -
and the first hatchway door slid open.
      It was the door to a little cabin, three-quarters filled with
variously shaped metallic containers stacked against the walls.
Jamie closed the door, went along to the next one and opened
that. This door too gave on to a cabin, but the cabin was
furnished with two bunks, a central table and two padded
chairs, all built in.
      Jamie became aware that the Doctor had come over to
join him. The Doctor looked round the little cabin. ‘Living
quarters?’
      Jamie nodded. ‘Aye. Stores in the other one.’
      There was some kind of machine standing upright
against the far wall - a dispensing-machine, thought the
Doctor. They went over to examine it.
      ‘Hey, it says “water” on here!’ said Jamie.
      They began experimenting with the controls...

     There was movement in the empty control room. A
squat bulbous shape glided silently out of the shadows. It was
a servo-robot, a simply designed affair that was little more
than a metal cylinder on running tracks with bulb-like sensors
on its upper surface. It was making a routine inspection.
Trundling up to the control room door the robot paused for a
moment. One of its sensor-globes glowed and the door slid
open. The robot moved off down the corridor.

     After a lot of jiggling and fiddling, the Doctor managed
to persuade the dispensing-machine to produce two plastic
cups filled with ice-cold distilled water. They stood sipping the
water gratefully.
      Jamie looked round. ‘I’d have thought a rocket this size
would have carried more than two people.’
      The Doctor nodded. ‘It does. Four, I imagine; two
resting, two on duty.’
      He went to the cabin’s viewing hatch, which was covered
by a metal shutter. The Doctor began unscrewing the clamps
that held it closed.
      ‘The TARDIS must have gone crazy,’ said Jamie.
‘There’s nothing on board here with us, so there’s no danger!’
      ‘Isn’t there?’ The Doctor beckoned Jamie over to the
window. ‘Come and look!’
      Jamie looked. Through the viewing hatch he saw -
nothing. The infinite blackness of space.
      ‘We appear to be drifting aimlessly in space, Jamie.
Maybe that’s what the TARDIS was trying to warn us about.’
      Jamie shrugged. ‘What does it matter?’
      ‘Matter!’ said the Doctor indignantly. ‘We’re just a piece
of drifting space flotsam, don’t you realise that?’
      ‘Aye, all right then. All you have to do is replace yon rod
what d’you call it, the dimension thingy...’
      ‘The Time Vector Generator,’ said the Doctor patiently.
‘It controls the temporal drive.’
      ‘Aye, that thing. You just put it back and we go on
somewhere else.’
      ‘I’m afraid it isn’t as simple as that, Jamie, remember?
First we need mercury to replace the fluid links.’
      ‘Aye, well, there must be some on board here.’ Jamie
was ever optimistic.
        The Doctor however was still feeling vaguely uneasy.
‘Besides, what happened to the crew, Jamie? They didn’t just
pop out for a little constitutional, you know!’
        ‘We might find that out if we get inside that control
room.’
        The Doctor nodded thoughtfully. ‘Perhaps, Jamie.
Perhaps.’ His mind was busy with a dozen theories - and none
of them were particularly reassuring.
        When the TARDIS warned of danger, it was never
wrong and the Doctor felt things were happening on this
ship, somewhere out of view.
        ‘Well, let’s start looking,’ he said, and they began their
search.
        They searched every inch of the motor section and the
whole of the store room as well. They found stores, supplies,
fuel, tools, protective clothing, space suits, any number of
useful and interesting things - but not what they were looking
for.
        ‘Not a drop of mercury anywhere,’ said the Doctor
despairingly. They were back where they’d started, in the
little cabin.
        ‘Maybe we’d better try the control room,’ suggested
Jamie.
        ‘I think you’re right, Jamie. We’ll have a bit of a rest and
try there next.’
        Jamie eyed the dispensing-machine. ‘D’you think we
might get food as well as water out of that thing?’
        ‘I can give you another sherbert.’
        ‘I was hoping for something a wee bit more substantial,
Doctor.’
        ‘Right! Let’s see what we can do then.’ The Doctor went
over to the machine and studied the controls. He was
beginning to get the hang of it now. ‘What do you fancy,
Jamie?’
       ‘Oh... roast beef and all the trimmings.’
       ‘What vegetables?’
       ‘Potatoes and cabbage.’
       ‘And you’d like a fruit salad?’
       ‘Aye, I would.’
       The Doctor’s hands moved over the controls. ‘And I’ll
have... pork chop, potatoes, carrots and... and some ice
cream.’
       A moment later two small paper plates emerged from
the machine’s dispensing compartment. They held a selection
of cubes of jelly, in different colours and sizes. The Doctor
handed one to Jamie. ‘There you are, complete with gravy.’
       Jamie stared down at his plate in horror. ‘Ye dinna
expect me to eat this stuff, do you?’
       ‘Why not? I’m sure it’ll be delicious.’
       Jamie looked at his plate and then at the Doctor who
was already munching one of his cubes with every sign of
enjoyment.
       Jamie sighed. ‘I didn’t expect a five-course dinner, but
this is ridiculous!’
       ‘It’s perfectly good, Jamie. Come on, sit down and eat
up!’
       Jamie sat down obediently and began munching
gloomily on one of the cubes. It had a vague, faint ghost of a
fruity taste, and Jamie realised he must have started on his
dessert by accident. Still, what did it matter?
       ‘What do you think Victoria’s doing now, Doctor?’
       The Doctor smiled. ‘All depends when “now” is Jamie. If
I knew that I might be able to hazard a guess.’
       ‘Och, you know what I mean.’
      ‘Victoria will be all right,’ said the Doctor reassuringly.
‘She chose a good time in Earth’s history to stay in, no wars,
great prosperity, a time of plenty. She’ll be happy, never fear.’
He noticed that Jamie had pushed his plate of food
concentrate aside. ‘Filling, isn’t it?’
      ‘Aye,’ said Jamie sourly. ‘Well, what do we do now?’
      ‘We’ll give ourselves time to digest our food, then we’ll
have a go at getting into that control room.’
      ‘Aye, good idea. I think I’ll just have a wee lie down.’
Yawning, Jamie stretched out on one of the bunks. ‘What do
you think’s happened to the crew?’
      ‘I don’t know, Jamie, I wish I did. I’m inclined to
suspect that there was some sort of disaster. Perhaps we shall
find some clue to the answer in the control room.’

     In its methodical patrol through the corridors of the
space rocket, the servo-robot came to the door that the Doctor
had opened some time earlier. It stood studying the open
door for a moment, its sensor-globes flashing agitatedly. The
door was open. It was supposed to be closed, according to the
information on the robot’s built-in data bank.
     Something was badly wrong.

      The Doctor was staring out of the viewing port. ‘At least
this ship doesn’t seem to be in any immediate danger.
However, I’d very much like to know what really happened.’
The only answer was a long rattling snore. The Doctor turned
and saw that Jamie was fast asleep.

      The servo-robot was standing in front of the TARDIS,
its sensor-globes flashing wildly in robot astonishment. Faced
with an event totally outside its programming, it was
completely and utterly at a loss.

      Attached to the control console in the rocket control
room was a strangely alien looking device. Somehow it was
clear that it was the product of a very different technological
culture from the one that had originally built the ship. It was
some kind of clock device with three separate hands. One
revolved swiftly and silently, like the second hand on a watch.
      The second made a series of sudden jumps at regular
five-second intervals. The third moved less frequently,
covering a whole quarter section of the dial at a time. Above
the clock was a small digital register. It was currently reading
one thousand and twenty-five.

      The robot abandoned the problem of the TARDIS’s
presence on board. Since it was impossible it could not have
happened so it was not a problem.
      Trundling back along the corridor, it applied itself to
the problem of the open door. Passing through, it turned to
face the door from the other side. It flashed its sensor-globes
at the control panel and the door slid shut. The robot
extruded a metal rod from the upper part of its body. Light
glowed at the end of the rod, and the robot moved the laser-
beam carefully around the edges of the door, sealing them
shut.
      Satisfied it moved back towards the control room.

     Tucking a space-blanket around Jamie’s sleeping form,
the Doctor straightened up and headed for the cabin door.
He had decided to let Jamie sleep, and to make the attempt to
reach the control room on his own.
      Just as he reached the door, he paused listening. Had
there been some kind of sound from the corridor outside? A
sound of movement? Cautiously he opened the cabin door
and stepped out into the corridor.
      Looking down he saw track marks on the floor. Fresh
track marks, overlaying the ones he’d already seen. Yet the
corridor was empty...
      The Doctor moved along to the bank of monitor
screens. He operated controls, but this time he got nothing
but a swirl of static.

      By now the servo-robot was back in the control room. It
was standing next to the main computer bank, extruding a
power cable from its body. The cable locked home, plugging
in to a socket on the computer bank. Needles flickered, lights
flashed, and the ship’s computer, with its pre-programmed
automatic pilot, hummed into life. Orders were transmitted
across the ships operation circuits - and suddenly the rocket
motors surged into life.
      Changing direction abruptly, the ship set off on its new
course...

      The sudden lurching of the ship took the Doctor
unawares as he was leaning forward to study the monitor
controls. Hurled across the corridor, he struck his head on
the steel wall and slumped unconscious to the ground.
                           3
                         Hunted
      The lurch that threw the Doctor into the wall sent Jamie
hurtling from his bunk. He thumped onto the floor, rolled
over, and scrambled to his feet - to find the Doctor gone. He
hurried out of the cabin to look for him.
      At the far end of the corridor he saw the Doctor
stretched out on the ground. As Jamie watched, the Doctor
stirred and began making feeble attempts to get to his feet.
      Jamie ran to help him. ‘Doctor! What’s happening?’
      The Doctor groaned. ‘Hit my head...’
      Jamie helped him to sit up. All around them was the
deep hum of machinery, the subdued roar of the rocket’s
motors. ‘We’re moving, Doctor... The rocket’s moving!’
      ‘I know...’ The Doctor clasped his aching head. ‘There
must be someone inside the control room.’
      ‘Let’s have a look, then!’
      The Doctor shook his head dazedly. ‘No, Jamie, help me
back to the TARDIS, that’s the safest place for us.’
      ‘But we still havena found the mercury...’
      ‘Never mind that now... back to the TARDIS, Jamie.’
      Jamie helped the Doctor to rise, half supporting him as
they staggered along the corridor, heading for the spot where
they’d left the TARDIS. The door that led out from the motor
section was closed. Jamie stabbed at the controls, but nothing
happened. He examined the edges of the door. ‘It’s sealed,
Doctor!’
      The Doctor stared blankly at him - and collapsed.
      Catching him just in time, Jamie half-dragged, half-
carried him back to the little cabin and laid him down on the
bunk. The Doctor revived for a moment. ‘Lock the door,
Jamie.’
      ‘But Doctor...’
      ‘Lock it...’ The Doctor’s head fell back.
      Jamie went over to the door, closed it, and operated
what seemed to be a locking device. He turned back to the
bunk. ‘Doctor...’
      But the Doctor was unconscious.

       In the rocket control room, a complicated series of
events was unfolding, according to a pre-determined plan.
       The servo-robot had disconnected itself from the
computer bank and was concerning itself with the coffin-like
metal pod that occupied the centre of the control room. The
robot’s sensor lights flashed and the top of the pod slid open
revealing rows of opaque globular objects resembling some
kind of alien eggs. A hatchway opened in the rocket wall, and
the metal pod slid inside it. The hatchway door closed.
       In the control room the alien clock clicked down to zero
- and a strident signal sound filled the control room...
       A hatchway opened on the exterior of the rocket and the
alien eggs began drifting away into space, one by one... When
the pod was empty the hatchway closed.
       Its tasks completed, the servo-robot turned towards a
monitor screen. Sensors flashed and the screen sprang into
life. On it there appeared the Wheel, a giant man-made space
station, one of humanity’s distant outposts in this remote part
of the cosmos.
      From the cabin porthole Jamie was staring in fascination
at the Wheel.
      It was vast, colossal, dominating what had seemed, only
minutes ago, to be an empty sector of space. To Jamie’s eyes it
looked like a giant metal spinning top, with a saucer-like
superstructure and some kind of supporting framework
underneath.
      So absorbed was Jamie by this astonishing sight that he
failed to notice that the Doctor was sitting up on the bunk and
gazing dazedly around him. He rose unsteadily and moving
like someone sleepwalking, opened the door and staggered
off down the corridor. By this time the Doctor was suffering
from mild concussion, and he had only one idea in his head.
‘Must get door open... get Jamie to safety...’

      Kept moving only by sheer determination, the Doctor
staggered up to the sealed door. He fished in his pocket and
pulled out the black-tipped gold rod that he had taken from
the TARDIS.
      The Time Vector Generator was in itself a tremendously
powerful energy-source - one which could be adapted in
emergency to many strange uses...
      The Doctor slipped the black cap from one end of the
rod to reveal a fiercely-glowing tip. He pointed it like a torch,
running it along the sealed edges of the door.
      There was a crackle of power, and smoke drifted from
the sealed edges. The Doctor re-capped the gold rod, slipped
it back in his pocket. Shaking his aching head to clear it, he
turned his attention to the door controls. They seemed to
surge and ripple before his eyes. Shaking his head
determinedly he forced his bleary eyes to focus and reached
out for the controls. Then he sensed rather than heard that
there was something behind him.
      Slowly the Doctor turned - and found himself facing the
servo-robot.
      As the Doctor turned the robot shot back several feet -
almost as if it was frightened of the Doctor. Then it extruded
the nozzle of the laser-gun from its body. The Doctor was not
part of the Plan. He was an error. Errors must be erased.

       Recovering from his astonished reaction to the Wheel at
last, Jamie turned to the Doctor. ‘Hey Doctor, come and look
-’ But the Doctor was gone. The crumpled space blanket
trailed from the end of the bunk and the door stood open.
       Snatching up the blanket - he had a confused idea that
the Doctor ought to be kept warm - Jamie shot out of the
cabin and into the corridor...
       He dashed along it, arriving just in time to see the
confused, half-conscious Doctor being menaced by the robot’s
laser gun. Jamie acted instantly.
       Draping the blanket over the servo-robot’s squat form,
he gave the robot a powerful shove that sent it shooting down
the corridor. Grabbing the Doctor by the shoulders, Jamie ran
him back down the corridor into the comparative safety of the
cabin, closing and locking the door behind them.
       To do this he had to let go of the Doctor, who slid
quietly to the floor, completely unconscious...

     A blast of the servo-robot’s laser sent the blanket
shooting into the air in charred and tattered fragments. The
robot glided swiftly down the corridor after the Doctor and
Jamie, coming to a halt outside the locked cabin door...
     The nozzle of the laser-gun glowed fiercely, and smoke
began rising from the metal door...

      As Jamie heaved the Doctor back on to the bunk a fierce
crackle of energy came from the direction of the door. Jamie
looked and saw smoke rising and a pin-point hole that was
growing steadily larger.
      The Doctor opened his eyes and saw what was
happening. Fumbling in his pocket he took out the gold rod
and thrust it into Jamie’s hand. ‘Use it like a torch, Jamie...
burn... be careful... careful...’ The Doctor gestured feebly
towards the door - the hole was much bigger now.

     In the corridor, the servo-robot had already melted
away a sizeable patch of the metal door - there was a puddle
of molten metal at its feet. Soon the door would be melted
and the two mistakes could be erased.

     Obeying the Doctor’s feebly muttered instructions,
Jamie took the end off the gold rod and directed the energy-
beam through the hole in the door. The beam struck the
servo-robot in the centre of its mid-section.
     Results were immediate and spectacular. The robot shot
backwards at enormous speed, smashed into the still closed
door and blew up, disintegrating into smoking metallic
fragments.
     Jamie settled the Doctor on the bunk and found another
blanket to cover him. ‘We seem to be safe for a little while. But
no more gallivanting about, Doctor.’
     Exhausted by his efforts, the Doctor was dead to the
world. Jamie settled him as comfortably as he could and then
went over to the porthole, looking out at the gleaming shape
of the Wheel. There had to be people on a thing like that, he
thought. Maybe they would come and help...

      The control room of the Wheel was very different from
that of the rocket. It was huge and brightly lit, with a big semi-
circular control station with places for all the crew members.
      Leo Ryan sat in the command chair, a big, handsome
fair-haired giant of a man, cheerful and confident, sometimes
to the point of arrogance. Next to him was Tanya Lernov, a
slim attractive young woman with a bell of fair hair framing
her sensitive face. Standing behind them was Gemma
Corwyn, medical officer of the Wheel, a pleasant-looking
sensible woman in her mid-thirties.
      ‘Hold it steady,’ snapped Ryan. ‘Get a proper fix on that
thing!’
      Gemma said mildly, ‘It seems to have stopped moving.’
      Ryan glanced at Tanya. ‘How is it now, Tanya?’
      ‘Stable. Exactly the same.’
      Gemma said, ‘Isn’t there a slight drift still?’
      Ryan shook his head. ‘No. The movement’s not real. It’s
an illusion caused by slight polar precession.’
      A stocky, balding bearded man came into the control
room and there was an immediate respectful silence.
      This was Jarvis Bennett, Commander of the Wheel.
Dressed like his subordinates, in quilted black and white space
coveralls, he was in his own quiet way a figure of considerable
authority. ‘Well, how’s our mystery rocket?’
      Gemma shrugged. ‘Suddenly lifeless, apparently.’
      Ryan frowned. He hated mysteries. ‘It doesn’t make
sense, Commander. It must have been driven by something.’
      ‘There’s been no radio contact at all,’ added Gemma.
       Jarvis Bennett said, ‘I’m not surprised. I’ve just checked
out its description on the Register. It’s a Phoenix Mark Four,
named Silver Carrier.’
       ‘Register even,’ said Tanya. ‘No crossover reading.’
       Ryan said, ‘It’s definitely stopped moving. No
momentum at all now.’
       Gemma looked at Jarvis Bennett. ‘Silver Carrier, you
said?’
       ‘That’s right. Supply ship for Station Five. It was
reported overdue about nine weeks ago. It’s only about ninety
million miles off course.’
       Ryan glanced towards the dark, silent man at a nearby
sub-console. ‘Try radio contact again, Rico.’
       Enrico Casali was the Wheel’s communications officer.
Olive-skinned, brown-eyed and curly-haired, his appearance,
like his name reflected his Italian origins, though there was no
trace of accent in his voice. ‘Space Station Three to Silver
Carrier. Station Three to Silver Carrier. Come in please.
Come in please.’
       ‘Ninety million miles?’ said Gemma. ‘It couldn’t have
drifted all that way, Commander.’
       ‘No, it couldn’t.’
       ‘Try the emergency channel, Leo,’ suggested Tanya.
       Ryan leaned forward to his console mike. ‘Station Three
to Silver Carrier. Operate red band switch for emergency
transmission.’ They all waited tensely, but there was no reply.
       Gemma Corwyn said, ‘Maybe their radio’s dead.’
       ‘We have to try,’ said Tanya.
       Jarvis Bennett nodded approvingly. ‘Standard
procedure. I’m afraid we’re wasting time, but waste it we
must.’
       ‘Any reaction, Tanya?’ asked Ryan.
       ‘No, nothing. No response at all.’
       ‘So how does the Silver Carrier turn up in this part of
the cosmos?’ mused Gemma.
       Jarvis Bennett said thoughtfully, ‘Say something
happens to the crew, illness or accident. One of them manages
to put on the automatic pilot. The rocket’s travelled so far by
now the power feed-back is probably failing. So the rocket
could start up and stop again more or less any time.’
       ‘And what about the crew?’ asked Gemma. ‘Do you
think they’re still alive?’
       Jarvis Bennett looked at Ryan, who shook his head.
‘We’ve tried everything, sir. Can’t raise a thing.’ Jarvis
Bennett said, ‘If I’m right about that faulty automatic system,
that rocket could accelerate at any moment - and whip
straight towards us. And there can’t be any life on board after
all this time - can there?’

      Like soap bubbles from the bubble pipe of a child, the
alien eggs drifted through the space between the rocket and
the Wheel...
      As the eggs struck the surface of the Wheel, they seemed
to sink right through it, as if somehow the Wheel was
absorbing them.

      Tanya looked up from her instruments with a frown.
‘I’m getting some kind of reading. Like very small meteorites
hitting our outer rim. No damage, but there’s a very slight
drop in air pressure.’
      ‘Can’t be meteorites, surely,’ said Gemma. ‘We’d have
had some warning.’
      ‘Well, there’s something,’ said Tanya. ‘These readings
are jumping all over the place.’
      Jarvis Bennett had the explanation. ‘I imagine minor
objects, with small mass and high density, have escaped from
the Silver Carrier.’
      ‘In that case,’ said Gemma, ‘such objects would be
clinging close to the rocket, not descending on us.’
      Jarvis Bennett didn’t care for having the flaws in his
theories pointed out. ‘It really doesn’t matter, Gemma, let’s
not start looking for mysteries. The point is, I daren’t risk that
rocket homing in on the Station and smashing into us.’
      ‘So what are you going to do?’
      Jarvis Bennett smiled. ‘You’re about to experience
something rarely seen by human beings. Is the laser projector
on standby, Leo?’
      ‘Yes, sir. Moving into position now.’
      As the rumble of heavy machinery filled the control
room Jarvis Bennett said, ‘I’m going to turn our laser-cannon
on the Silver Carrier. In a few moments you will see the
complete destruction of a rocket in space.’

      From the cabin in the rocket, Jamie stared out at the
Wheel. He glanced briefly at the still unconscious Doctor.
Surely the people on that thing would see them and send
help...
      Unaware that is was preparing to blast him from
existence, Jamie stared hopefully out at the Wheel...
                      4
                Command Decision
      As Jamie watched, a hatch slid back on the upper part of
the Wheel and a massive metal tube slid slowly into view.
Jamie looked thoughtfully at it. His knowledge of space
technology was patchy to say the least, but his fighting-man’s
instinct knew a weapon when he saw one. This thing looked
unpleasantly like the muzzle of a gun. And it seemed to be
pointing straight towards him...

       In a sectioned-off area of the control room, Bill Duggan
a thick-set, amiable-looking defence officer was supervising
Laleham and Vallance, two technicians who were preparing
the laser-cannon for operation.
       Jarvis Bennett stood watching them. ‘Got the range,
Bill?’
       ‘Locked on now, sir.’
       ‘That’s the idea. Don’t get much fun, do we Bill? Better
make the most of it!’
       Bill Duggan grinned. ‘Makes a change from blasting the
occasional meteorite, sir.’
       Jarvis Bennett nodded. ‘Tanya? How about taking a
visual recording?’
       ‘Can do, sir.’
       ‘Right. I’d better make a crew announcement.’
       Gemma Corwyn hurried over to him. ‘Could I have a
word first, Jarvis? It’s important.’
       Glancing across the control room, Jarvis Bennett caught
Leo Ryan’s eye and smiled. ‘More bogies,’ he said in a stage
whisper. But he allowed Gemma to take his arm and lead him
aside.
      Tanya Lernov looked at Ryan and snapped, ‘I don’t
know what you’re grinning about!’
      Hurriedly Ryan straightened his face. ‘Neither do I.’
      ‘This isn’t funny, Leo. The Commander’s so keen to use
the laser, he’s like a kid with a new toy.’
      ‘Don’t say you agree with old stick-in-the-mud Gemma
Corwyn?’
      ‘Doctor Corwyn isn’t old and she’s no stick-in-the-mud
either. She’s quite right to be cautious.’
      ‘Oh come on, Tanya,’ said Ryan wearily. ‘That rocket is
nine weeks overdue and ninety million miles off course.
There can’t possibly be anyone alive on board...’

      Jamie’s instincts had led him to an almost uncannily
accurate estimate of the situation. For some reason, the Wheel
had decided that the rocket was a danger to it, and it was
going to destroy the intruder.
      His only hope was to make some kind of signal. He tried
to wrench a light panel from the wall, but with no success.
The light wouldn’t be bright enough anyway. Jamie looked
desperately at the Doctor, hoping he would be recovered
enough to give some advice.
      The Doctor was still unconscious - but the gold rod was
lying beside him on the bunk.
      Well, it had worked a treat on the robot, thought Jamie.
It was worth a try.

     Since she believed that rows between senior personnel
were best held in private, Gemma Corwyn had taken the
Commander back to her living quarters.
      Much larger and more luxurious than the cramped
living quarters on the rocket, Gemma’s rooms were soothingly
decorated in pastel shades. She was the Wheel’s psychiatrist as
well as medical officer, and her quarters doubled as her
consulting room.
      Jarvis Bennett had a nasty suspicion that he was being
viewed as a potential patient.
      ‘Don’t subject me to your psychoanalysis,’ he roared.
‘You think I’m acting like a kid again don’t you? Bang, bang,
blow up the balloon! Well, you’re wrong!’
      ‘Am I?’
      ‘The Silver Carrier is a menace to the Wheel.’
      ‘Only if you equate menace with automatic power drive,
which I don’t. You want me to believe some emergency
occurred on the Silver Carrier, the pilot switched over to
automatic, then - tragedy. Is that it, Jarvis?’
      ‘Right!’
      ‘And the crew are all dead?’
      ‘Right again!’
      ‘Where was the Silver Carrier bound for?’
      ‘I told you, it was servicing Station Five.’
      ‘Then wouldn’t the automatic have taken it to Station
Five?’ asked Gemma triumphantly.
      Jarvis Bennett stared at her. ‘That’s good reasoning. But
the emergency might well have damaged the control sensors -
which would explain why the rocket went off course.’
      ‘Assumptions, Jarvis. Guesswork. It would be so easy to
check.’
      ‘We can’t risk that rocket crashing into the station,’ said
Jarvis obstinately. ‘She’d blast a hole right through us.’
      Jamie stood hesitating by the porthole, the gold rod in
his hand. If the Wheel interpreted his signal as an attack. Still,
something had to be done.
      Aiming the gold rod at the Wheel, Jamie whipped the
black tip off one end - seconds later he replaced it.

      Tearing the earphone from his head, Enrico Casali
staggered back from the console. Rudkin, a neighbouring
technician did the same.
      Ryan ran over to them. ‘What is it, Enrico?’
      ‘Some kind of power surge... static, noise. Tremendous
noise! Right through me like a knife. Swamped everything...’
      All over the control room, astonished technicians were
cursing and rubbing their ears. Lights were flashing wildly on
all the consoles.
      Bill Duggan shouted, ‘What’s going on? The whole
system’s gone crazy!’
      ‘Tanya, get Doctor Corwyn,’ ordered Ryan.
      ‘The internal communications are out.’ Tanya jumped
up. ‘I’ll go and get her.’
      Ryan went over to help Enrico, who was easing Rudkin,
much more badly affected than he was himself, away from the
controls.
      ‘All right, Rudkin,’ Enrico said soothingly.
      ‘Lie him down over here,’ said Ryan.
      They settled the unfortunate Rudkin, who was still
moaning and clasping his ears, on a bench at the side of the
control room.
      Enrico massaged his ears. ‘I don’t want to go through
that again...’
      ‘Listen!’ said Ryan.
     The energy pulse could still be distinctly heard, coming
through the sets of ripped-off headphones. It was coming in a
steady, but uneven beat - like some kind of signal.

     ‘Don’t argue with me, Gemma,’ shouted Jarvis Bennett.
‘The decision is mine. I command this Station and all the
people in it.’
     The door was flung open and Tanya dashed in. ‘Doctor
Corwyn, Rudkin’s hurt.’
     ‘What happened?’
     ‘Colossal static pulses, swamping all the detectors.’
     Jarvis Bennett glared angrily at Gemma. ‘I knew that
rocket was a menace!’
     They hurried from the room.

     Unaware of the havoc he was causing, Jamie stood by
the rocket porthole, capping and uncapping the gold rod at
irregular intervals.

      Tanya, Gemma and Jarvis Bennett came back into the
control room at a run.
      ‘Tanya, you get back to your console,’ ordered Jarvis
Bennett. ‘See if you can pin this static down. Gemma, see what
you can do for Rudkin and the others.’
      As Gemma began organising the transfer of Rudkin and
the worst-hit of the other technicians to the medical bay,
Jarvis took his seat at the console. ‘All right, Leo, that rocket’s
given us more than enough trouble. Knock it out!’
      ‘Commander!’ called Tanya urgently.
      ‘Yes, what is it?’
      ‘That static - it’s a signal.’
      ‘It can’t be!’
      Leo Ryan held up his hand. ‘She’s right, sir. Listen!’
      They listened.
      It was quite clear that the irregular beat of the static was
forming some kind of pattern.
      ‘Get me a fix on it, Tanya,’ snapped Ryan.
      ‘If I can. It’s no code I’ve ever heard of, but there’s
definitely a repetitive order to it.’
      ‘You think it’s coming from the rocket?’ asked Jarvis
Bennett.
      ‘I just want to make sure, Commander.’
      Tanya looked up. ‘The rocket it is, sir. There’s no
doubt.’
      Jarvis Bennett was a good enough commander to admit
it when he was wrong. ‘Then there’s someone on board that
thing. Leo, I want two men to cross over.’
      ‘Right, sir.’
      Jarvis Bennett shook his head unbelievingly. ‘Ninety
million miles off course. If anyone is still alive on that ship,
they must be in a pretty bad way...’

      Jamie had given up on his signalling by now, and was
staring down at the still unconscious Doctor in despair.
Suddenly he heard a tapping from the porthole. Swinging
round he was shocked to see a helmeted head peering at him
from outside the rocket.
      Then realising that the longed-for help had arrived,
Jamie grinned broadly and waved. The helmeted figure
pointed towards the front of the rocket. Jamie nodded and
hurried from the cabin.
      As he hurried along the corridor, he stepped gingerly
over the shattered remains of the servo-robot, then made his
way towards the control room.
      As he reached the door it opened before him and he
went inside. One space-suited figure was already there, and
seconds later, a second emerged from the air-lock.
      ‘Quick!’ shouted Jamie urgently. ‘I’ve got someone hurt
back there.’
      The two space-suited figures hurried after him.

      It was some time later and for the moment the Wheel
seemed almost back to normal.
      Ryan and the other technicians were acting as deep
space traffic controllers and weather men, confirming the
routes of space freighters, issuing warnings of meteor showers
and generally smoothing the complex process of
interplanetary travel.
      Leo Ryan looked up as Tanya came into the control
room. ‘How are our guests?’
      ‘Doctor Corwyn’s looking after them now. They both
seem to be in shock.’
      ‘What happened to them?’
      ‘Nobody knows. It’s still a mystery.’
      Ryan grinned. ‘Jarvis won’t like that.’ Something on one
of the read-out screens caught his attention. ‘What’s that
interference on Green System, Chang?’
      The technician looked up. ‘It’s very odd, sir. Been
getting funny signs here and there for some time. As soon as
you check them out - they vanish!’
      ‘You’ve been logging them?’
      ‘Yes, sir.’ Chang frowned. ‘It’s as if we had magnets
touching the outer skin of the Wheel then letting go again.
Localised field effects, that’s all.’
      His co-technician, a massive Irishman called Flanagan
said, ‘But all field detectors check out normal, sir. Can’t be
anything serious.’
      Ryan nodded. ‘Keep logging it - and keep me up-to-
date.’ He smiled at Tanya. ‘More mysteries.’
      Tanya didn’t return the smile. ‘I know. And what about
those sudden drops in air pressure? Small enough and they
soon adjusted themselves - but I still don’t like it.
      ‘How small?’
      ‘One degree - sometimes one-and-a-half.’
      Ryan shrugged. ‘Could be a minor fault in the air supply
pumps.’
      ‘In so many different parts of the Wheel?’
      ‘Did you tell the Commander?’
      ‘Of course. And he bit my head off.’
      Ryan nodded sympathetically. ‘That figures. Did you tell
Doctor Corwyn?’
      ‘Not yet. She’s busy with the new arrivals. I didn’t like to
disturb her.’
      Ryan said seriously, ‘I’d start a check on the whole air
supply system if I were you, Tanya.’
      ‘I already have. Leo?’
      ‘What?’
      ‘All these mysteries. The temporary faults in your
systems, the air pressure drops. They all started with the
rocket, didn’t they?’
      Ryan chuckled. ‘Reckon there are little green men on
board, do you?’
      But Tanya didn’t smile. ‘What about those two people
they brought back from the rocket?’ she asked. ‘They weren’t
exactly normal.’
     ‘I tell you what, Tanya - if you get scared I’ll let you hold
my hand, okay?’
     He gave her one of his cheeky grins, and Tanya couldn’t
help smiling in return. ‘Leo, I’m serious.’ Ryan raised his
eyebrows. ‘So am I!’

     Meanwhile, outside the Wheel, a string of silvery
bubbles drifted onto the outer skin then disappeared,
somehow seeming to pass through the metal.
     The long-prepared invasion had begun.
                         5
                  Under Suspicion
      Jamie was sitting uneasily in the medical bay, stripped to
the waist. Gemma Corwyn was passing a stethoscope-like
instrument over his chest.
      ‘Breathe in... out. Now a deep breath and let it out
slowly.’
      Meekly Jamie obeyed.
      ‘Good,’ said Gemma Corwyn crisply. ‘You can get
dressed now.’
      Jamie rose and began struggling into his shirt. ‘How’s
the Doctor?’
      ‘Well, he’s certainly suffering from concussion. I’m
waiting for X-rays to see if there’s a fracture.’ She paused.
‘Look, your clothes... fancy dress or some-thing?’
      Jamie was stung. ‘Have you thought what you’d look
like if you walked down the street in those clothes-people
might think you were a wee bit strange!’
      ‘But we’re in space - you’re the ones who aren’t
conforming.’
      Jamie changed the subject. ‘How about the medical. Do
I pass?’
      ‘If it’s any comfort, you’re in excellent physical shape.
What’s your full name?’
      ‘James Robert McCrimmon - Jamie for short.’
      ‘And your friend?’
      ‘The Doctor?’
      ‘I can’t just put that down.’
      Jamie glanced round for inspiration. ‘Er, Smith. John
Smith.’
      As she fitted the stethoscope back into the diagnostic
machine and lifted the whole thing back into its container, she
noticed the name on the open lid. ‘John Smith and Co.
London’.
      Jamie followed her gaze. ‘Er - there’s a lot of them
about.’
      ‘Yes indeed,’ said Doctor Corwyn drily. ‘You and your
friend were passengers - on the Silver Carrier?’
      ‘What? Oh, aye, we were. Could I have a drink of water,
please?’
      Gemma went to a dispensing-machine and returned
with the usual plastic cup of distilled chilled water. She
handed it to Jamie who took a couple of sips and put down
the cup. ‘What happened to the crew?’ she asked.
      ‘I dinna ken.’ Jamie swallowed hard, desperately
wishing the Doctor was here. He could talk his way out of
anything. Jamie floundered on. ‘I was ill in my cabin, terrible
raging fever. I was raving for days. When I got up there was
no one about, the doors were closed against us and the Doctor
was hurt... Then your people came and rescued us.’
      ‘Your friend couldn’t tell you what had happened?’ ‘No.
He was too ill.’
      ‘All right, Jamie, that will do for now. The Commander
will want to have a chat with you - and of course we must see
about getting you home.’
      ‘Home. That’ll be the day,’ said Jamie wryly, thinking of
the Scotland of 1746. He’d no chance of reaching that without
the Doctor - precious little with him, he sometimes thought.
Jamie became aware that Doctor Corwyn was staring at him
and said hurriedly, ‘Aye home. Yes, of course.’
       ‘There’s another ship passing through in a week or two.’
       Jamie pulled on his jacket and began knotting his scarf.
‘Can I go now?’
       Gemma was still looking curiously at him. ‘You haven’t
finished your water.’
       ‘No, well, that’s all right...’ Jamie began edging away.
       ‘Would you like to see round the Wheel?’ asked Gemma
suddenly. ‘I could arrange it for you.’
       ‘Aye, why not - nothing else to do,’ said Jamie rather
ungraciously.
       Gemma Corwyn pointed. ‘If you go through that door
and along the corridor you’ll find a door marked
Parapsychology Library.’
       ‘Parawhat?’
       ‘It’s on the far side of the Wheel, about eight sections on.
I’ll ask Zoe to show you around.’
       ‘Zoe?’
       ‘She’s our - well, you might call her our librarian.’
       ‘Right, fine,’ said Jamie. ‘You’ll let me know how the
Doctor gets on?’
       ‘Of course.’
       Jamie nodded and hurried away.
       Gemma Corwyn picked up a mike from a nearby
console. ‘Doctor Corwyn calling Parapsychology.’
       After a moment a young girl’s face appeared on a
monitor screen. ‘Library. What reference do you require,
Doctor Corwyn?’
       ‘No reference, thank you Zoe. I need your help in
another way. One of the people retrieved from the rocket is
coming to see you. I want you to show him over the Wheel -
and observe him. Discreetly, of course.’
       ‘Do you wish these observations recorded?’
      ‘Yes please, Zoe.’
      ‘Right,’ said the girl briskly. ‘Should be interesting. Any
other facts known?’
      Gemma Corwyn smiled. ‘Well, he’s a nice lad. His name
is -’
      ‘Just a minute,’ interrupted Zoe. ‘I was half-way through
a RNA analysis, just let me clear my head...’ She clicked her
tongue, shook her head then smiled. ‘Right, fire away!’

       It took Jamie quite some time to find the
Parapsychology Library, but he managed it at last and tapped
hesitantly on the door. It opened immediately. Jamie stepped
through and it closed behind him.
       He found himself in a small completely bare room, in
the centre of which was a semi-circular desk, also completely
bare. Behind the desk sat a very small girl, or rather young
woman. She wore the same black and white coverall outfit as
everyone else on the Wheel and her appealing rather pixie-
like face was framed with shortish black hair.
       She was rattling something off into the microphone of
the video-link built into the otherwise empty desk. ‘... with the
exception of the Hercules cluster. Computation shows that
one of the stars in the Messier Thirteen group is entering a
nova phase - information on gamma radiation level is
available...’
       The girl broke off as Jamie came in. ‘You must be James
Robert McCrimm -’ She stopped again, with a little gurgle of
laughter.
       ‘Aye, McCrimmon,’ completed Jamie. ‘What are you
laughing at?’
       The girl was looking at the kilt that swung round
Jamie’s brawny knees. ‘You’re wearing female clothes!’
        ‘Female!’ Jamie was outraged. ‘This is a kilt. Have you
no’ seen one before?’
        ‘Kilt?’ She frowned and closed her eyes, as if calling up
the information. ‘“Kilt: a primitive form of garment, worn by
a kiltie.” Are you of Scandinavian origin?’
        ‘No I am not. I’m a true bred Scot!’
        ‘Ah, Scot - Scotland. Pre-century history isn’t really my
field.’
        Jamie had had quite enough of being patronised by
some bossy wee girl. ‘Mebbe not - but you’d better not give me
any more of your Sassenach lip, or I’ll bend you over my knee
and larrup you!’
        The girl looked at him with delighted amusement. ‘Oh
this is going to be fun - I can learn a great deal from you,
James Robert McCrimmon. Come on, I’ll show you round.
My name’s Zoe, by the way...’

       Some time later, Jamie was feeling tired and more than
a little dazed. He had seen the generator area, the computer
section, the astro-navigational guidance complex, the space
meteorology area, and a whole lot more, and his guide, the
wee girl Zoe seemed to know absolutely everything about
everywhere they’d seen.
       Impressed and amused by her enthusiasm, Jamie had
done his best to look interested, but he couldn’t help thinking
how much more the Doctor would have got out of the tour.
       Now at last they were somewhere Jamie could take an
interest in - a sort of mini greenhouse which their host, a
stocky, cheerful fair-haired man called Bill Duggan had set up
in the Wheel’s main power room.
      The rows of exotic alien plants in their carefully laid-out
growing trays made a strange contrast to the gleaming
technological environment all around them.
      ‘This is my little kingdom,’ said Bill Duggan proudly.
‘How do you like my greenhouse?’
      Jamie nodded appreciatively. ‘Just fine. Where do you
collect all these things?’
      ‘Floating seeds, most of them. The only place they seem
to flourish is down here in the power room. The Commander
kicked up a dust storm at first, but Doc Corwyn said it was
good therapy or something - me, I just like flowers.’ Lovingly
he stroked the petals of an exotic black and scarlet blossom.
‘This one comes from Venus. Imagine that, all those millions
of miles away!’
      ‘Twenty-four million, five hundred and sixty-four
thousand miles at perihelion, one hundred and sixty-three
million three hundred and fifty thousand at aphelion...’ Zoe
rattled off the information as if someone had touched the
read-out button on a computer.
      ‘Aye, thanks,’ said Jamie. ‘I was just dying to know!’
      Bill Duggan grinned and led them into the main body of
the room. ‘This is the capacitator bank for the laser-cannon,
Jamie. Without it the gun’s useless.’ He indicated a massive
central installation, shaped rather like a giant mushroom, its
transparent dome crammed with complex electronic circuitry.
      Jamie studied it respectfully. ‘What do you need a
cannon for, out here in space?’
      Duggan shrugged. ‘Self-defence - we can blot out any
attackers for ten thousand miles in any direction!’
      ‘Reassuring,’ said Jamie drily.
      Bill pointed to another similar installation. ‘Anti-
magnetic field generators over there. They fend off even
medium-sized meteorites for up to five miles.’
      Jamie turned to Zoe. ‘The Doctor will be verra keen to
see all this!’
      ‘This Doctor friend of yours,’ asked Zoe curiously. ‘Is he
a scientist?’
      ‘Aye.’
      ‘What’s his speciality? Is he a physicist, bio-chemist,
astronomer, bio-metrician...’
      ‘Aye,’ said Jamie. ‘That’s right!’
      ‘He sounds an interesting character,’ said Bill Duggan.
‘When’s he going to be up and about?’
      Jamie sighed. ‘I wish I knew...’

       The Commander was asking Doctor Corwyn exactly the
same question.
       She looked thoughtful. ‘Well, if the concussion’s not too
serious, before very long.’
       Jarvis Bennett wasn’t happy with her answer. ‘That
doesn’t tell me much. I want some facts.’
       ‘I don’t blame you.’
       ‘Landed with a couple of strays,’ grumbled Jarvis. ‘All
these mystery panics from the crew. Routine’s getting shoddy,
I don’t like it.’
       ‘What panics?’
       ‘Mysterious untraceable faults, air presure drops.
Nothing serious. People are getting edgy.’ He strode restlessly
about the consulting room. ‘Out in space people need routine,
ordinariness. Confuse them and you get trouble.’
       Gemma Corwyn watched him thoughtfully, thinking
that it was his own feelings that he was really expressing.
      As if sensing her thoughts Jarvis said hurriedly. ‘Of
course I’m used to emergencies, trained to cope. But all this
nonsense...’
      ‘What you call mysteries, panics...’
      ‘Exactly! I don’t want to know, Gemma!’
      And that was the literal truth, thought Gemma Corwyn.
Jarvis Bennett was a man for procedures, routines. The
unknown would always be his greatest fear.
      ‘Do you want to hear my preliminary report on the boy
Jamie?’
      ‘All right, go on.’
      ‘He’s lying. Not completely, and apparently reluctantly.
He’s very fit, mentally and physically, with a nice constructive
personality. His blood pressure suggests he hasn’t been long
in space.’
      ‘What has he lied about?’
      ‘He said he’d had fever on the Silver Carrier, but he
hadn’t - his blood shows no trace of it.’
      ‘But why lie about that?’
      ‘I asked him to explain what had happened to the crew -
fever was his excuse for not knowing. I think he lied about his
companion’s name - John Smith.’
      ‘Well, they do exist, you know!’
      Gemma showed him the label on the diagnostic
machine. ‘He was looking at this at the time. Coincidence
possibly, but I doubt it. What’s the most precious thing in
deep space, Jarvis?’
      ‘Air, water... take your pick...’
      ‘And the training that teaches you not to waste them.
Even one-journey travellers know that.’ She leaned forward.
‘He asked me for a drink of water - and then left it! He might
have been on Earth. The boy hasn’t had space training, Jarvis.
He must be a stowaway...’
      Immediately Jarvis Bennett’s fear surfaced again.
‘Sabotage!’ he said explosively. ‘He must be some kind of
agent! But whose...’
      ‘Well, plenty of people on Earth think we should
suspend the space programme, use the resources to tackle
Earth’s problems. Some of them have tried to enforce their
ideas...’
      Jarvis Bennett seized on the theory enthusiastically. ‘So
these two stowed away on the Silver Carrier, disposed of the
crew, pretended to drift here helplessly. We take them in and
they start to sabotage the Wheel. Of course, everything fits!’
      ‘It’s a possibility, Jarvis - there are others...’
      ‘We’ll discuss them later.’ Jarvis Bennett was already
heading for the door. ‘This could be serious. I’ll deal with
these people myself!’
                           6
                    Birth of Terror
      Unaware that her guest had been branded a secret
agent and potential saboteur, Zoe was still showing Jamie
round, and explaining all about the operation of the Wheel.
‘Now, this is the main Operations and Communications area -
the control room in other words.’
      Jamie looked round the control room. ‘Aye - but what’s
the Wheel doing up here in space?’
      ‘It’s a radio-visual station for Earth, a half-way house for
deep-space travel, a space research station, a stellar early
warning       system    for     potentially    dangerous    space
phenomena...’
      Jamie grunted. ‘Aye well, ask a silly question!’ He
dropped into one of the swivel chairs behind the main
console.
      ‘Not there,’ said Zoe hurriedly. ‘That’s the
Commander’s chair!’
      Jamie got up and he and Zoe moved over to Leo Ryan,
who swung round and beamed cheerfully at them. ‘You two
are in for a treat.’
      Bill Duggan, who’d tagged along on the tour said, ‘The
old man’s going ahead, then?’
      ‘Too right he is!’
      Tanya Lernov looked up. ‘I thought Doctor Corwyn had
talked him out of it?’
      ‘Only because she thought someone might be on board.’
He grinned at Jamie. ‘Lucky for you, young feller.’
      Jamie gave him a baffled look. ‘Sorry, you’ve lost me.’
Zoe explained. ‘The Commander, Jarvis Bennett... apparently
he wanted to destroy the rocket.’
      ‘We got your message just in time,’ said Tanya. Leo
Ryan nodded. ‘I’ll say. Only minutes in it, the lasers were all
primed and ready to go.’
      Tanya said, ‘And now Jarvis has given the go-ahead to
try again?’
      ‘That’s right. I’ve run a new co-ordinate fix to be sure.
The whole thing’s primed and ready, all we need is the final
signal.’
      Jamie was horrified. ‘You’re no’ going to blow up the
rocket? What for?’
      ‘Commander reckons its unsafe,’ said Ryan. ‘Might go
out of control and ram us. So, to be on the safe side, we blast
it out of existence first.’
      Tanya said, ‘Jarvis asked for a visual record, I’d better
re-position the camera. Zoe, come and help me recalculate
will you, you’re quicker than the computer.’
      As Zoe and Tanya moved across to the nearby camera
console, Jamie began edging towards the door...
      ‘Should be very interesting this,’ Ryan was saying. ‘It’ll
be quite an explosion.’
      Jamie slipped out of the door. Nobody noticed him go.

     Jamie strode boldly along the corridors of the Wheel.
One or two of the technicians looked curiously at him, but no
one challenged him.
     He had a good sense of direction, and he managed to
find his way back to the power room without two much
trouble. There were Bill Duggan’s flowers, and there close by
was the capacitator bank - vital to the operation of the laser-
cannon. Jamie began looking around. He opened a locker,
and studied a row of aerosol cans on a shelf...

      Jarvis Bennett meanwhile had just strode into the
control room in search of Jamie. He was far from pleased to
be told that the boy seemed to have disappeared. ‘He was
definitely here?’
      Zoe said, ‘Yes, Commander, Doctor Corwyn asked me to
look after him.’
      ‘We were showing him round,’ added Bill Duggan
helpfully. Jarvis Bennett winced. ‘Round where?’
      ‘Everywhere. We’d just come from the power room...’
      ‘The power room,’ said Jarvis thoughtfully. He
beckoned Duggan aside and whispered urgently. ‘Bill, don’t
say anything to the others. Just follow me out quietly when I
go. Zoe, not a word about this to anyone.’
      ‘Right, sir,’ said Zoe obediently.
      With a warning frown, the Commander marched out of
the control room.
      Zoe gave Bill Duggan a puzzled look. He shrugged.
‘Don’t look at me, I’ve no idea what’s going on!’
      Tanya Lernov came over to join them. ‘Problems, Bill?’
      ‘I don’t know,’ said Bill Duggan awkwardly. ‘All in your
mind, dear.’ He hurried off.
      By now Tanya was sure something was going on. ‘What
was the Commander talking to Bill Duggan about, Zoe?’
      ‘Nothing important,’ said Zoe. ‘At least, I don’t think so -
I don’t know. Does it matter?’ She too hurried away.
      Thoughtfully, Tanya went back to the console.
      ‘What’s all the whispering about?’ asked Leo.
      ‘I wish I knew. Leo, did I ever tell you about my nose?’
      ‘What about it?’
      ‘It’s like a barometer, it never lets me down... and I
smell trouble.’
      ‘Can you pin point where?’
      ‘I think it’s got something to do with that rocket out
there. There’s something sinister about it...’
      They turned to look at a monitor screen. On it there was
a picture of the abandoned rocket, drifting in space.

       On board the rocket, something was happening.
       The alien clock which had counted down to zero had re-
set, and now the number on the digital read-out was
mounting: 997, 998, 999...
       As the count reached a thousand, a harsh electronic
screeching filled the control room. Lights came on in a
darkened section to reveal two giant silver spheres. Power
leads connected them to a machine of the same alien design as
the countdown clock. The machine began to hum with power
and the silvery spheres started to glow.
       As they lit up they became semi-transparent, revealing
inside the crouched shapes of giant humanoid figures, bent
over, knees to chin, like some ghastly parody of a human
embryo.
       The transparent membranes of the spheres began to
expand as the figures inside stirred, slowly flexing arms and
legs. It was like some weird and uncanny process of birth. The
difference was that these creatures would not be born small
and helpless but huge and powerful, ready to conquer and
destroy.
       A massive silver fist smashed open one of the spheres,
and the towering monster within began rising to its full
height...
                            7
                          Menace
      ‘I tell you, Leo,’ said Tanya Lernov obstinately, ‘There’s
trouble on the way. My nose never lets me down!’
      Gently Leo touched the nose in question with his finger.
‘Well, don’t over-work it, it’s much too pretty to risk
damaging its shape.’
      ‘Just don’t say I didn’t warn you. That rocket’s
dangerous.’
      ‘Not for much longer it isn’t. Once Jarvis gives the go-
ahead, we’ll blast it out of existence.’

      Thoughtfully Jamie studied the label on the aerosol can
in his hand. ‘Liquid Plastic’. Underneath was written,
‘Unmeltable, Unbreakable, Everlasting’.
      ‘That ought to do it,’ thought Jamie grimly and, lifting
off the protective dome, he began spraying the plastic right
into the heart of the capacitator bank. He shot the plastic in at
random, aiming for the most complex looking sections of the
equipment in the hope of doing as much damage as he could.
      Suddenly a hand gripped his wrist, wrenching the can
away from the machinery, twisting the wrist savagely so that
Jamie was forced to drop the can.
      ‘Red-handed!’ said an angry voice in Jamie’s ear.
      Twisting round, Jamie saw he was in the grip of a
stocky, balding, bearded man. Beside him was a horrified Bill
Duggan. Grabbing a pair of gloves from the bench, Duggan
grabbed a can of solvent from the locker and began squirting
it into the machine. He shot Jamie a reproachful look. ‘What
do you think you’re doing you fool?’
       The bearded man tightened his grip on Jamie’s wrist.
‘Oh no, he’s not just a fool, Bill. He’s a saboteur!’
       Bill Duggan stopped his spraying, and shook his head.
‘It’s no good, Commander. He’s wrecked it.’
       ‘Completely?’
       Bill nodded. ‘The stuff’s had time to harden.’
       ‘Watch him,’ ordered the Commander. He shoved
Jamie towards Bill, who stepped back and snatched up a
spanner from the work bench.
       Jamie held up his hands. ‘All right, I’ll not give you any
trouble.’
       ‘Too right you won’t,’ said Bill grimly.
       Jarvis Bennett was talking into a wall communications
unit.
       ‘This is the Commander. Now hear this: all men on
security duty are to draw side-arms immediately. Yellow Alert
to be put into operation immediately. Two men from Security
to report to the power room on the double.’

      In the control room, Ryan turned to Tanya. ‘Yellow
Alert? What’s the sudden panic?’ He rose. ‘I’ll have to go and
log out the blasters. Keep an eye on the Hercules cluster, will
you, Tanya? Zoe thinks one of the stars in Messier Thirteen is
going nova.’
      ‘That’s all we need, a star blowing itself to a million
pieces. I told you my nose was never wrong!’

     Two massive silver figures now sat at the rocket controls.
Approximately man-shaped, they were much bigger than any
man, a good seven feet tall, perhaps more. They seemed to be
formed of some uniform silvery material, something with the
qualities of both metal and plastic. Faces, bodies, arms and
legs and the complex apparatus that formed the chest-unit, all
seemed to be of a piece, made from the same gleaming silvery
material. Their faces were blank, terrifying parodies of the
human visage, with small circles for eyes and a thin letter-box
slit for a mouth. The heads rose to a sort of crest into which
was set what looked like a kind of lamp. Two strange handle-
like projections grew out from the head in place of ears.
       The Doctor, had he been there would have recognised
them instantly. They were Cybermen.
       At the moment they were busy with the communications
equipment that had been installed in the rocket by their
fellow Cybermen. A monitor screen had been fitted on to the
rocket control console, with a control panel beneath.
       As one of the Cybermen adjusted controls with a giant
silver hand, first a sleek and sinister-looking space ship
appeared. After a moment the ship faded, and the screen was
filled by the head of the Cyber Planner.
       The head, shaped similarly to that of the Cybermen
themselves, was even more featureless, semi-transparent so
that the convolutions of the great brain within could be dimly
seen.
       The Cyber Planner was a creature of pure thought. He
had no physical functions as such, and was, in fact, no more
than a vast living brain.
       ‘Report,’ said the Planner from the screen. His voice had
a blurred electronic quality.
       The first Cyberman replied in the same eerie voice.
‘Phase One complete.’
       ‘The Cybermats are launched?’
       ‘Phase Two complete.’
     ‘You are undetected on the rocket?’
     ‘Phase Three now prepared.’
     ‘Report again after completion of Phase Three.’
     The screen went dark.

      ‘Yellow Alert,’ blared the communications system.
‘Yellow Alert all sections.’
      Security men hurried along the corridor, buckling on
their hand blasters.
      Zoe and Doctor Corwyn came along the corridor.
      ‘You’d better check your theory with the computer,’
Gemma Corwyn was saying.
      ‘Oh, I know I’m right,’ said Zoe confidently. ‘Hercules
208 in Messier Thirteen is definitely on the blink. I can tell
what the radiation effect will be on Earth if you like.’
      ‘Not now, Zoe,’ said Gemma Corwyn gently.
      They came to the corridor junction where their ways
separated.
      ‘I suppose you’re going to see the fun, whatever it is,’
said Zoe.
      Gemma Corwyn said, ‘Somehow, Zoe, I don’t think this
is going to be fun.’

     Flanked by two armed security guards, Jamie was
watching Bill Duggan complete his examination of the
damaged machinery.
     Jarvis Bennett stood looking on impatiently. ‘Well?’
     Duggan straightened up, glaring at Jamie. ‘You did a
good job, boy!’
     ‘What’s the exact damage?’ demanded the Commander.
     ‘It’s very serious, sir. All the primary relay contacts are
fused shut. The whole unit will have to be stripped down.’
       ‘How long?’
       ‘Depends how much plastic he used, and how far it
penetrated.’
       ‘How long?’
       ‘I don’t honestly know, Commander.’
       ‘Surely you can give me some idea. You know as well as
I do, without the laser-cannon we’re virtually helpless.’
       ‘Well, if we assume the worst - that the central storage
charge unit is absolutely finished - it could take best part of a
week.’
       Gemma Corwyn hurried in and took in the tense scene.
‘What’s the trouble, Jarvis?’
       He gestured savagely at Jamie. ‘This young idiot has
ruined the laser - poured quick-seal plastic right into the relay
lines for the Branston mirrors.’
       ‘But why?’
       ‘Sabotage - just as we said.’
       ‘No!’ protested Jamie.
       Jarvis Bennett swung round on him. ‘What - are you
one of these “Pull Back To Earth” maniacs? I suppose your
friends are out there in deep-space, waiting to attack us now
you’ve put our laser out of action...’
       ‘You’re talking rubbish,’ said Jamie.
       Bill Duggan looked up from the machinery. ‘You can’t
deny it. We saw you.’
       ‘I’m not denying anything,’ said Jamie sulkily.
       Gemma Corwyn was looking shocked. ‘Is the laser really
out of action, Jarvis?’
       ‘It is.’
       ‘But Zoe calculated there’s a new star going nova. We
haven’t checked fully yet, but she’s usually right.’
       Jarvis Bennett looked grim. ‘How bad is it?’
      ‘Zoe calculates that the radiation flux will swing the
meteor shower straight in on us. With the cannon we could
knock the worst of them out.’
      ‘I’d better get on with this as quick as I can,’ said Bill
Duggan. He hurried to the communicator. ‘Maintenance! Get
me maintenance... All hands to the power room, immediate
and urgent!’
      Jarvis Bennett said, ‘We’ll go and check Zoe’s
calculations on the radar computers. Bring the boy along!’
      The Commander, Doctor Corwyn, Jamie and his two
guards all left the power room, leaving Bill Duggan to
contemplate the ruined capacitator bank, and await the
maintenance team.
      He shook his head sadly. ‘What a mess!’ Suddenly a
flash of movement caught his eyes. Something small and
silvery had scuttled out of an open cupboard. Bill Duggan
knelt to examine it.
      At first glance it seemed like a sort of metal mouse, but
when you examined it closer it was more like some kind of
insect. Its scaled, segmented body was roughly triangular,
with a sort of fringe around the base, and two huge red eyes
glowed on the top of its head.
      It shot backwards a foot or two as Bill approached, and
then froze motionless. ‘Hang on,’ said Bill gently. ‘I’m not
going to hurt you.’ He reached out slowly, and when the
creature didn’t move he carefully picked it up. ‘Well, well,
well, where do you come from, eh?’ He tapped the hard
metallic shell. ‘You’re a strange little creature aren’t you?
Some kind of space bug...’
      Perhaps it had come on board with one of his alien
plants, he thought, grown maybe from some kind of egg - the
cosmos was full of strange and wonderful things.
      Whatever it was, Bill Duggan felt a sort of proprietary
interest in it. When he heard the footsteps of the maintenance
men approaching he said, ‘I think I’d better hide you, Billy
Bug - they’ll think I’ve gone bonkers.’
      He popped the creature back into the storage cupboard
and closed the door.

      Jarvis Bennett swung round from the computer read-
out screen. ‘Radar computers Two and Five both confirm
Zoe’s calculations.’ He jabbed an angry finger at Jamie.
‘Didn’t know what you were letting yourself in for, did you
boy? Ever been in a sky station when the meteorites hit?’
      ‘Look, I’m sorry,’ growled Jamie.
      ‘Why did you do it?’ asked Gemma.
      Jamie turned to the Commander. ‘They said you were
going to give orders to blow up the rocket.’
      Jarvis nodded. ‘So?’
      ‘I couldna let you, that’s all.’
      ‘Why not?’
      Jamie looked round the circle of angry and concerned
faces. ‘Because the Doctor told me to protect the rocket.’

      ‘Oh well, that’s marvellous, isn’t it?’ said the Doctor
bitterly. ‘“The Doctor told me to protect the rocket”. Don’t
bother about a convincing reason, will you? Just leave me to
get you out of trouble!’
      They were in the Doctor’s room in the medical section.
Jamie had refused to say another word until he had a private
meeting with the Doctor, and after a lot of what Jamie called
havering, his request had been granted.
       The Doctor, looking very much better, was stretched out
on a couch, clearly in a sort of half-way stage between being ill
in bed and properly up and about.
       ‘Look, I had to stop them destroying the rocket, didn’t
I?’ said Jamie desperately.
       ‘I suppose so.’
       ‘You know very well so! What about the TARDIS eh?
Fine thing if they’d blown that to pieces!’
       The Doctor sighed. ‘And I was so enjoying this little
rest.’
       ‘What are you going to tell them, Doctor?’
       ‘I’ve no idea - Jamie - what exactly did happen on that
rocket? And there’s no need to look at me like that!’
       ‘Ye canna remember?’
       ‘Well, it is a bit hazy.’
       ‘I found you out in the corridor, by that locked door.
Something must have shook up the rocket. It tumbled me out
of bed. It must have made you stumble and hit your head as
well.’
       ‘I hit my head?’
       ‘Don’t you remember anything, Doctor?’
       ‘Oh, I will. I will. Things keep lurking at the back of my
mind.’
       ‘How about that robot thing in the corridor? The one
that was about to attack you. Do you remember that?’
       ‘I’m afraid I don’t.’
       Jamie sighed despairingly. How was the Doctor going to
solve their problems if he couldn’t remember what they were?
       The Doctor was staring into space. ‘But there’s
something in the back of my mind, Jamie... Some warning.
Some menace...’
     The Cyber Planner’s head was once more on the
rocket’s monitor screen. ‘Report progress.’
     The leading Cyberman said flatly. ‘All phases
proceeding as planned.’
     ‘Excellent! Prepare Phase Four...’
                           8
                    The First Death
        Enrico Casali and his colleagues were busy at the radar
computer console. Leo Ryan, Tanya and Zoe were clustered
round, anxious to learn the news that might determine their
fate.
        ‘Band eighteen,’ ordered Enrico.
        The technician adjusted the controls.
        Enrico nodded. ‘Too far - now back a bit. Try a cross-
fix... just a touch more... it’s coming clearer now.’
        ‘Getting it?’ asked Leo urgently.
        ‘I think so... that’s it... there! Hold on that and turn up
the gain.’ Enrico turned to the others, indicating the star
chart on the screen. ‘You see? It’s all happening in the
Hercules cluster all right.’
        ‘I told you,’ said Zoe brightly. ‘The same thing
happened in the Perseus cluster a week ago, remember?’
        Tanya said, ‘Only then we had the laser-cannon to
deflect the biggest meteorites.’
        Casali tapped the screen. ‘You see? It’s beginning to
emit hard gamma already.’
        ‘Is it bigger than the Perseus one, Enrico?’ asked Leo.
        ‘At least four magnitudes up.’
        Leo Ryan winced. ‘Well, better give the Commander the
bad news.’
        Tanya touched his arm. ‘What are we going to do - if
they can’t repair the laser in time?’
        ‘There’s still the forcefield...’
      Zoe shook her head. ‘That won’t help us. When a star of
this magnitude goes nova it deflects meteorites with a mass of
two hundred tons or more.’
      Tanya shuddered. ‘Two hundred?’
      ‘At least,’ said Zoe cheerfully.
      ‘Aren’t you ever wrong?’ snarled Ryan.
      ‘Rarely.’
      ‘It’s all a problem in solid geometry to you, isn’t it?
Don’t you care what happens to us?’
      ‘Of course. I’m only telling you what’s going to happen.’
      ‘Yes, just like a robot. Facts, calculations. Little brain
child, all brain and no heart!’ Ryan strode away, and with an
apologetic look at Zoe, Tanya followed him.
      Zoe stared after them, a puzzled frown on her face.

      Bill Duggan was supervising a team of maintenance men
as they lifted the central core out of the capacitator bank.
‘That’s it... steady. Get that down to the workshops and start
stripping it right away... I’ll be along in a moment.’
      As the men staggered out of the door with the heavy
piece of machinery, Bill Duggan glanced down and saw a
flash of silver. It seemed to be coming from the bottom of a
half-open cupboard door. He bent down and saw the silvery
bug shooting out of the door. It froze as he bent down.
      ‘Hello, Billy Bug. You should’ve stayed where I put
you...’ Duggan stared into the cupboard his eyes widening.
There was a metal bar just inside the cupboard on the floor -
or rather, half a metal bar. The other half was corroded, eaten
away.
      Bill Duggan stared at the bug. ‘Hey, did you do that?’
      He opened the cupboard door. There was a tumbled
pile of metal bars scattered inside the cupboard. Every one of
them was partially eaten away. Duggan picked up one of the
bars and was astonished to feel it crumble between his fingers
like rotten wood.
      ‘What have you done?’ he said appalled. He looked
down, but the silvery space bug had disappeared.
      A technician called Rudkin came into the power room,
and Bill Duggan wheeled around, wild-eyed.
      Rudkin looked curiously at him. ‘What’s the matter?’
      ‘Nothing,’ said Duggan hurriedly. ‘How’s it going?’
      ‘The Commander asked me to come down and see if
you needed any help. He asked how things were going.’
      ‘You can tell him we’re doing our best. Actually, there is
something you could do for me. Look in on spares and ask
them to give me a stock position on Bernalium, would you?’
      ‘Sure.’ Rudkin went out and Duggan turned back to the
devastated store cupboard.
      He unearthed an untouched stack of Bernalium bars at
the very back and gave a sigh of relief. ‘That lot’s all right
anyway. I’ll murder that little beast...’
      He turned away, closing the cupboard door firmly
behind him. A silver space bug flashed across the floor, and
froze just by the cupboard door. Its eyes glowed, the door
opened and the space bug shot inside...

     Gemma Corwyn was examining the Doctor, using a
diagnostic machine much like the one she’d used on Jamie.
The Doctor still in shirtsleeves submitted meekly to her tests,
watching with interest as the bleeping electronic stethoscope
passed over his body, flashing its results on the little screen.
     Gemma Corwyn sat back, putting the instrument away.
‘You and your friend are amazingly healthy specimens,
Doctor. Though some of these readings are...’
      ‘Well, we all keep fit as best we can,’ said the Doctor
hurriedly. ‘Does this mean I’ve got to get up?’
      ‘Not quite yet, I’m afraid.’
      ‘Oh good.’
      ‘Does your head ache?’
      ‘It did at first, but it’s better now.’
      ‘Any loss of memory?’
      ‘Just a little.’
      ‘Does that make you anxious?’
      The Doctor smiled. ‘Not unduly. I think you’ll find my
psyche quite in order.’
      ‘Possibly. But you mustn’t strain to remember.
Concussion does interfere with memory - like having a word
on the tip of your tongue. There’s quite a bit we don’t know
about the memory bank.’ She smiled, then added casually, ‘I
suppose the bit you can’t remember is why you told Jamie to
protect the rocket.’
      ‘Oh no, I remember that all right,’ said the Doctor
cheerfully. ‘We’re not saboteurs, you know. The last thing we
want is to interfere with your work, or put you in any danger.
You saved our lives and we’re very grateful.’
      ‘But you have interfered,’ Gemma pointed out coolly.
‘We’re in the path of a meteorite storm and we’ve no defence
against it.’
      ‘I didn’t know about the meteorites,’ said Jamie. ‘I didna
really ken what they were!’
      The door opened and Zoe shot in. ‘Is it all right? The
guard on the door let me in.’
      The Doctor frowned. ‘Guard?’
      ‘We can’t let you roam wherever you want to,’ Gemma
pointed out. ‘Not any more.’
      ‘We’re under arrest,’ said Jamie glumly.
       ‘How did you pilot the rocket so far, Doctor?’ asked Zoe.
       The Doctor frowned. ‘I don’t think we’ve met.’
       Gemma Corwyn said, ‘Zoe, this is Doctor... John Smith,
isn’t it?’
       ‘What? Oh yes, that’s me,’ said the Doctor hurriedly.
‘And what do you do on the Wheel, Zoe?’
       ‘I’m an astrophysicist - a pure mathematics major.’
       ‘Really? I’m impressed.’
       ‘We use Zoe as our second opinion,’ explained Gemma.
       Zoe wasn’t to be put off. ‘You didn’t answer my
question, Doctor.’
       ‘What question?’
       ‘How did you pilot the rocket ship so far? There’s a
record of the last contact with the Silver Carrier. It had seven
million miles to touchdown and fuel for twenty million. It
couldn’t have drifted ninety million miles off course in the time
involved. It must have been driven and piloted. Somehow the
rocket was refuelled in space, provided with at least another
twelve fuel rods.’
       ‘That’s a very interesting theory, Zoe.’
       ‘It isn’t a theory, Doctor, it’s fact. Pure logic.’
       ‘Logic, my dear Zoe, merely allows you to be wrong with
authority. Suppose a faulty automatic pilot was at work?’
       ‘Driving a rocket ninety million miles on fuel for twenty
million? That rocket was driven here somehow, Doctor. I
know it was!’
       The worrying thing, thought the Doctor, was that Zoe
was almost certainly quite right.

     The Cybermen were once again in conference with their
Planner.
      ‘We have ionised a star,’ announced the Planner. ‘Soon
meteorites will strike the Wheel.’
      The Cyberman said, ‘Phase Three is in operation.’
      ‘The Cybermats will consume Bernalium,’ droned the
Planner. ‘Without Bernalium the Wheel cannot deflect the
meteorites.’
      The Cyberman said, ‘They will discover Bernalium
aboard this ship. Phase Four is ready.’
      ‘Remove telemeter control from Cybermats,’ ordered
the Planner. His image faded from the screen.

      One of Bill Duggan’s space bugs - a Cybermat, to give it
its proper name - was crouching in a corner of the power
room. Suddenly its eyes glowed a fiercer red and it seemed to
pulse with malignant energy.
      The telemeter control, the device that rendered the
Cybermats harmless when they had specific tasks to perform
had been removed.
      Now they were killers.
      Rudkin came into the power room. ‘Bill?’ he called.
      Bill Duggan was nowhere to be seen. Rudkin was just
about to leave when the wall intercom flashed. Rudkin went
over, touched a control and the face of a technician appeared
on the screen. ‘Valiance from spares here. Bill Duggan
around?’
      Rudkin said, ‘No, I’m looking for him myself.’
      ‘You know we’re checking the Bernalium stock?’
      ‘Yes, Bill asked me to check up on it. I had a word with
Chang.’
      ‘Well, we’re a bit puzzled - most of the Bernalium stock
was transferred over to him in the power room weeks ago. Bill
must have got his wires crossed. Have a look round will you,
see if you can locate it?’
       ‘Sure.’
       ‘Call me back, will you?’
       ‘Will do.’
       The screen went blank.
       Rudkin started a methodical search of the many
cupboards and storage lockers that lined the power room.
       A Cybermat glided out of hiding and moved towards
him, its eyes flaring red...

       Bill Duggan was in Doctor Corwyn’s consulting room,
pouring out his unlikely story. His conscience wouldn’t allow
him to keep silent any longer - even if the Doctor did think he
was potty. ‘... and now the Bernalium’s useless, Doc.’
       What about the reserve?’
       ‘I asked for a check, but later I remembered. I’m
already holding most of it in the power room. You know how
much we rely on the Bernalium rods. They’re the only things
that stand up in the laser-cannon.’
       ‘And what about these creatures of yours... I’m far more
concerned about them.’
       ‘There’s only one - at least, that’s all I found.’ ‘Did
anyone else see it?’
       ‘No.’
       ‘Did you tell anyone about it at the time?’
       ‘You must be joking. They already think I’m a nut for
messing about with my flowers. How d’you think they’d react
if I started telling them I’d found a space bug?’
       Gemma looked thoughtfully at him. It could all be
delusion - but it didn’t sound like it. ‘What did this bug look
like?’
      Duggan held his hands a little way apart. ‘About so big...
cross between a fish and a rat. Big red eyes. Body feels like
metal or some light tensile material...’
      ‘And you say it eats metal?’
      ‘Not exactly. It sort of draws all the life out of it -
corrodes it. You should see what it does to Bernalium!’
      ‘But how did this thing get on the Wheel?’
      ‘Search me - I’m just the one who found it. Could have
got in through a loading bay, or one of the air locks.’
      Gemma looked dubious. ‘It’s possible, I suppose.’
      Duggan said worriedly, ‘What’s the matter? You think
I’m a nut, don’t you?’
      Gemma rose. ‘No, I don’t. But I’d like to see this thing
for myself.’
      Bill Duggan jumped up. ‘Okay, be my guest. I’ll
introduce you to Billy Bug with pleasure.’

      They were in the corridor near the power room when
they heard the scream. It was a terrible choking howl, like
nothing either had heard before. They began to run. The
scream echoed through the corridors of the Wheel. The
Doctor, Jamie and Zoe heard it in the medical section and
Jamie flung open the door of the Doctor’s room. He found
himself facing an armed security guard, a massive heavy-
featured Irishman called Flanagan. ‘You can’t come out,’ he
announced.
      ‘What was that scream?’ asked Jamie.
      ‘It sounded like all the devils of hell,’ said Flanagan. ‘But
you still can’t come out!’ He shoved Jamie back into the room
and closed the door.
      Bill Duggan and Gemma Corwyn rushed into the power
room - and found Rudkin sprawled on his back across the
trays of flowers. He was dead, and his face was twisted in
horror, as if death had frozen the scream in his throat...
                           9
                        The Trap
       Gemma Corwyn knelt to examine the body. After a
moment she rose, shaking her head.
       Bill Duggan was looking inside the open cupboard. The
last pile of Bernalium had been scattered and corroded like
the rest.
       There was an empty aerosol spray can lying near the
body... And there was something else.
       Gemma Corwyn knelt down and touched it. ‘What’s
this?’ Sealed to the floor was an irregularly shaped lump of
what seemed to be solid plastic...

       Some time later, the plastic lump was reposing on a tray
by the Doctor’s couch, with the Doctor, Zoe and Jamie all
peering at it.
       ‘The Commander’s mounting a full enquiry,’ said Zoe.
She tapped the lump. ‘But what I’m interested in is this!’
       The Doctor said thoughtfully, ‘Found by the body, was
it?’
       ‘They had to get one of the men to take up a floor plate.
The polymer strength of this plastic is higher than chrome
steel. You can’t cut through it.’
       ‘The Gordian Knot couldn’t be untied either,’ said the
Doctor quietly.
       ‘What does that mean?’
       ‘I think he means there’s always a solution,’ whispered
Jamie.
     ‘And the Bernalium is useless, is it?’ asked the Doctor.
Zoe nodded. ‘Completely. We’ve got a few spares, but
nowhere near enough.’
     ‘And the laser, the main defence of the Wheel relies on
Bernalium...’
     ‘Maybe there’s a real saboteur on the Wheel,’ suggested
Jamie. ‘Yon Bennett talked about some group or other...’
     ‘There are people who want to stop the space
programme,’ said Zoe.
     ‘Aye well, mebbe they planted someone on board. The
rocket comes along with us on board, and the saboteur uses
the opportunity and strikes.’
     ‘And murders?’ asked the Doctor.
     ‘If he was caught, he might have had to kill.’
     ‘It’s an interesting theory,’ said the Doctor.
     ‘Well, everything fits,’ said Jamie.
     The Doctor tapped the lump of plastic. ‘Except this.’
     ‘Och, it’s just a spare part. The man tried to defend
himself with the plastic and it misfired and went over some
lump of machinery.’
     ‘There’s one way we can find out,’ said the Doctor.
     ‘How?’ asked Zoe.
     ‘Use the X-ray machine!’ said the Doctor simply.

       In the control room, the Commander’s enquiry was in
progress. Jarvis Bennett sat behind a table, Doctor Corwyn
beside him. A miserable-looking Bill Duggan stood before the
table. ‘You’ll be sent back to Earth when the next ship comes
in,’ the Commander was saying. ‘I want a written report on
the whole affair in my hands first thing tomorrow. That’s all.’
As Bill Duggan turned away Jarvis Bennett said, ‘He’s to be
confined to quarters. Leo, you’ll have to take over some of his
operations. Tanya, you’ll have to cover for Leo.’
      ‘Very well, Commander.’
      Jarvis turned back to Leo Ryan. ‘Remember, I want the
laser working as soon as possible.’
      ‘Right, Commander.’
      Jarvis swung round. ‘Enrico, is the boarding party
ready?’
      ‘Laleham and Vallance are standing by, sir. Just waiting
for the go-ahead.’
      ‘Then give it!’
      ‘Commander.’
      As Enrico spoke into the intercom, Jarvis Bennett
turned to Gemma. ‘I want a word with you in your quarters,
Doctor Corwyn. As for the rest of you, let’s get back to normal
working conditions.’ Leaving a flurry of activity behind him,
Jarvis Bennett strode away.

     Bill Duggan was talking quietly to Tanya.
     ‘Sorry, Bill,’ she said quietly.
     ‘It was my own fault, I was a fool.’
     ‘You didn’t do anything.’
     ‘I should have told somebody straightaway when I saw
that creature. The old man doesn’t believe me, but it was
there.’
     Leo said, ‘We searched the whole power room, Bill.
There was a hell of a mess, but we didn’t see anything like
your bug.’
     ‘Well, I didn’t dream it... What’s the use? Rudkin’s dead,
and talking won’t bring him back.’ He moved sadly away.
      In Gemma Corwyn’s quarters the Commander was
letting off steam. ‘What’s the matter with you people? You
can’t turn round without dreaming up some little bit of
emotionally based fantasy. Did you hear that nut Duggan?
Space rodents! The man’s a wreck!’
      Gemma Corwyn drew a deep breath. ‘Jarvis, will you
listen?’
      ‘If it’s sensible, yes.’
      Gemma began counting on her fingers. ‘One: the rocket
drifts near us. Two: drops in temperature and air pressure,
adjusted back to normal. Three: two meteorite storms, both
above average dimensions, both within seven days. Four: two
strangers brought to the Wheel, one of them sabotages the
laser. Five: Bill Duggan’s apparitions, call them what you like,
turn up and corrode our Bernalium... just when we’re facing
a big meteor storm. I tell you Jarvis, that rocket is the base of
all our troubles.’
      ‘Don’t worry about it,’ said Jarvis complacently. ‘I’ve just
sent two men across to look it over. But, let’s have no more
mysteries...’

      After a certain amount of fiddling, the Doctor got the
plastic lump into the scanning field of the X-ray machine
beside his couch. Zoe was busy processing the prints.
      The results would appear on the machine’s little
monitor screen. At the moment the screen simply showed the
plastic lump.
      ‘Right, they’re ready,’ said Zoe. She slipped the negative
into the machine and flicked a switch.
      Suddenly the plastic lump seemed to melt away,
revealing a picture of the creature entombed inside.
      Zoe heard the Doctor and Jamie gasp. ‘What is that
thing?’ she asked.
      ‘A Cybermat,’ whispered the Doctor.
      Jamie said, ‘But that means there are Cybermen here
too then?’
      ‘That’s right, Jamie. And there’s only one place they
could be - on that rocket!’

      Propelling themselves by little thrusts from their oxygen
cylinders, Vallance and Laleham drifted across space towards
the rocket. A few minutes later they were clambering through
the air lock, and making their way into the control room.
      There was a crate in the centre of the control room, its
lid already pried off. Valance and Laleham went over to it,
and saw that it was piled high with Bernalium...
      They heard heavy footsteps, and turned to find two
giant silver forms towering over them. Laleham reached for
the blaster at his hip, but as he did so a bright light beamed
from the head of the Cyberman nearest him and he slumped,
dropping the blaster. A similar beam from the second
Cyberman was transfixing Valance. The beams brightened
and the two spacemen straightened up, their bodies rigid.
      The first Cyberman said, ‘You will take us to the Wheel.
Inside the Wheel you will help us. Obey!’
                         10
                    Trojan Horse
      Jarvis Bennett stared at the image on the X-ray
machine’s monitor screen - it showed a Cybermat entombed
inside the lump of plastic. ‘And what’s this supposed to
mean?’
      The Doctor said sombrely, ‘It means that the Wheel is
under threat from Cybermen.’
      Jarvis laughed scornfully. ‘Cybermen? Where did you
dream up a name like that?’
      Zoe was staring blankly ahead of her. ‘The study and
comparison of systems of control and communications in
living organisms and machines,’ she recited.
      ‘What are you talking about?’ snapped Jarvis Bennett.
      ‘Cybernetics,’ said Zoe.
      ‘I know what Cybernetic means, young lady, and I don’t
need any lectures from you!’
      ‘I tell you, Commander, these Cybermen do exist,’ said
the Doctor. ‘You must believe me - you must!’
      ‘On the evidence of one faked X-ray?’
      ‘It’s not faked,’ said Zoe indignantly. ‘I took and
developed it myself, Commander.’
      Jarvis Bennett looked angrily at the Doctor. ‘So what
exactly are these Cybermen?’
      The Doctor’s voice was grave. ‘They were men once -
human beings like you. They come from the planet Mondas.
Now they are more machine than man.’
      ‘You mean - half and half?’ asked Jarvis Bennett
uneasily.
      ‘More than that,’ said the Doctor. ‘Their entire body is
mechanised. Their brains have been treated neurosurgically
to remove all human emotion, all awareness of pain. They are
ruthless inhuman killers.’
      Jarvis Bennett laughed nervously. ‘You expect me to
believe all this rubbish?’
      ‘It isn’t rubbish, Commander, believe me. They’ll kill
anyone who stands in their way. You’ve got to believe me!’

      Laleham and Valiance looked on unmoving while the
first Cyberman climbed into the enormous crate, now
standing quite empty.
      The second Cyberman said, ‘You will take us to the
Wheel. Inside the Wheel you will help us. Now obey your
instructions.’ The second Cyberman climbed into the crate.
      Working together silently, the two men picked up the
false top that lay propped against the crate and fitted it into
place, so that it formed a sort of shallow tray, taking up the
top quarter of the crate. Into this space they put the boxed
bars of Bernalium. When they had finished the whole crate
appeared to be full. They fitted on the lid, hammering it into
place.
      Then Valiance moved to the communication unit.
‘Rocket to Wheel, Rocket to Wheel...’

      The Doctor was still trying to convince the Commander
of the danger they were facing. ‘Don’t you understand?
Somehow the Cybermen will get inside the Wheel.’
      ‘Nothing gets on and off the Wheel just like that. What
do you think this is, a heliport?’
      ‘Listen to him will ye?’ urged Jamie. ‘He’s telling you the
truth.’
      Jarvis turned on him. ‘No, I’ll tell you what he’s doing -
what too many others are trying to do - spreading fear...
alarm and terror. Do you think I can’t see it? It must be some
kind of space sickness...’
      Gemma Corwyn said, ‘Jarvis, you might at least listen...’
      ‘How could anything get inside the Wheel?’ demanded
Jarvis. ‘How will these creatures get through the air-locks? Or
will they just float through the loading bay in full view of
everybody?’
      ‘It’s still worth listening, and taking precautions,’ said
Gemma. ‘Just in case there is some truth in all this.’
      ‘Don’t try to tell me my job, Gemma. I’m still
Commander of the Wheel, and things will be done my way.
Any orders to the contrary will have to come from Earth
Control, and that’s what... that’s...’ His voice trailed off.
Suddenly he turned and marched from the room.
      The Doctor shook his head. ‘How do you convince a
man like that?’
      ‘I think Bill Duggan should see that X-ray,’ said
Gemma. ‘Go and get him, will you please, Zoe?’
      ‘Isn’t he still confined to quarters?’
      ‘Have him brought here under guard if necessary - you
can use my authority - but get him, Zoe. I’ll be responsible.’ As
Zoe hurried from the room, Gemma
      Corwyn continued, ‘Jarvis was right about one thing,
Doctor. These Cybermen of yours can’t just walk on to the
Wheel.’
      ‘You don’t know the Cybermen as I do,’ said the Doctor.
‘Believe me, they’ll find a way.’

    Valiance and Laleham were floating back towards the
Wheel, propelling themselves by puffs of oxygen from their
cylinders. Between them slung on a harness of ropes, there
floated the enormous crate.

       Vallance’s voice crackled from a speaker in the control
room. ‘Survey party returning. We are coming in through the
loading bay.’
       Tanya frowned. ‘Ask why. We’ve prepared airlock five.’
       Casali said, ‘Is anything wrong, survey party? Airlock
five is ready for you.’
       ‘Survey party to Control. We have discovered a large
crate of Bernalium on the rocket, and are bringing it over
with us.’
       ‘This’ll cheer the old man up!’ whispered Casali.
       Tanya nodded. ‘I’d better check with him though.’
       ‘Checking with Commander, survey party,’ said
       Casali. ‘Please await confirmation.’
       Tanya was already talking to Jarvis Bennett on the
internal visi-phone. ‘Survey party report a find of Bernalium
on the rocket, Commander. They want to bring it on board.
Shall I give the go-ahead?’
       Jarvis Bennett’s face beamed cheerfully from the screen.
‘Yes indeed, we need it badly. Somebody’s using their brains
at last. Good work!’
       Tanya nodded to Casali, and he spoke into his
communications mike. ‘All clear for cargo, survey party.
Loading bay will be clear for your arrival.’

       Bill Duggan was staring in astonishment at the picture
of the Cybermat on the X-ray screen. ‘That’s old Billy Bug all
right! What is it?’
       ‘An alien machine,’ said the Doctor. ‘Destructive, capable
of killing.’
       ‘I thought it was some kind of space rodent - I know you
all think I’m crazy...’
       ‘It’s a pity you didn’t tell someone about it straightaway,’
said the Doctor severely.
       Bill Duggan’s voice was defensive. ‘I told the old man
eventually - and look what happened? I got confined to
quarters!’
       ‘I’d better take you back,’ said Zoe. ‘Then I’ve got to do
some calculations on those meteorites - half the space fleet
might be flying into them.’
       ‘The meteorites, yes, of course,’ said the Doctor
suddenly. ‘The Cybermats must have been sent to put your
laser out of action - that’s why they attacked your stocks of
Bernalium.’
       Jamie looked relieved. ‘So even if I hadn’t put the laser
out of action, the Cybermats would have done it anyway.’
       ‘Are there any other defences?’ asked the Doctor.
       ‘There are magnetic field projectors,’ said Gemma. ‘The
Meson Shields. But they can only ward off small meteorites.’
       ‘Maybe their destruction of the Bernalium had some
other purpose,’ said the Doctor thoughtfully. ‘Wait a minute -
the rocket. There must be Bernalium on board the rocket...’

      The doors of the loading bay were open on to the
blackness of space. With eerie slowness the two spacemen
floated inside, bringing the crate between them. A space
suited technician stood waiting by the loading bay controls.
Once the two space-walkers and their cargo were safely inside,
he touched a control and the massive double doors slid closed.
Slowly he brought up the artificial gravity field and the two
men and their burden settled gently to the floor. There was a
sudden whoosh as he fed air into the chamber. He studied the
dials for a moment, then gave the two men a thumbs up sign.
Removing their helmets, all three men climbed the steep
flight of steps leading up out of the loading bay.
       The huge wooden crate was left on the floor of the
loading bay. The Trojan Horse of the Cybermen was on
board the Wheel.
                            11
                         Takeover
      Zoe was reeling off a string of calculations into her voice-
recorder when Jamie wandered into her library. ‘Hey, what
are you doing, talking to yourself?’
      ‘I was recording some very important readings, James
Robert McCrimmon - and now you’re recorded too!’
      ‘I’m not!’
      Zoe touched a control and Jamie heard himself saying,
‘Hey, what are you doing, talking to yourself?’
      He gave her an astonished look. ‘Och, have I ruined it?’
      ‘Not really. I thought you were confined to quarters?’
      ‘Och, I was going crazy - Doctor Corwyn told the guard
I needed to get out for a while - she’s keeping the Doctor as a
hostage!’
      ‘Well, you got off to a bad start, sabotaging the laser-
gun.’
      ‘I had to do that,’ said Jamie.
      ‘Why?’
      ‘I canna tell you.’
      Zoe looked curiously at him. ‘Tell me something else
then. Is the Doctor telling the truth - about these Cybermen?
Do they really exist?’
      ‘They exist all right. I’ve seen them!’
      ‘Of course, such creatures are theoretically possible,’ said
Zoe thoughtfully. ‘Given advanced cybernetic technology...’
      ‘Well, dinna be frightened,’ said Jamie reassuringly. ‘I’ll
look after you.’
     ‘Oh, I’m not frightened, just curious. I should very
much like to see one.’
     Jamie realised she was quite sincere. ‘Och, you’re a
funny wee thing. You take it all so calmly.’
     ‘All brains and no heart?’
     ‘I didna say that,’ protested Jamie.
     ‘No, Leo Ryan did.’
     ‘Well, he’s plain daft then!’
     Zoe smiled at him, ‘Jamie, these calculations are
urgent...’
     ‘Och, I can take a hint - I’m away!’ Jamie wandered off.
     Feeling strangely cheered up, Zoe went back to her
work.

      Jarvis Bennett strode purposefully into the power room,
Bill Duggan trailing behind him and surveyed the busy scene.
Leo Ryan and the burly Irish technician Flanagan were hard
at work on the capacitator bank, which seemed to be lying in
dis-assembled sections all over the power room.
      ‘How’s it going, Leo?’ asked the Commander.
      Leo Ryan straightened up. ‘Not too badly, sir. We’ve
been working non-stop.’
      ‘I’m giving you Bill Duggan here, Leo. No reason he
can’t make himself useful. Keep up the good work!’ Beaming
cheerfully, the Commander strode away.
      Ryan said, ‘Boy, am I glad to see you Bill! This thing’s
your baby, not mine.’
      Bill Duggan cast a skilled professional eye over the
machinery. ‘How’s it looking?’
      Well, we’ve had a bit of luck. The central deployment
complex didn’t get as much plastic as we feared. Maintenance
have sorted it out and sent it back.’ He pointed to the central
core which was scattered in pieces around the main console.
       Bill Duggan nodded. ‘That’s great! How about the
Bernalium problem?’
       ‘I haven’t got around to that one yet!’ Leo turned to
Flanagan.
       ‘Go on, you, hoppit!’
       ‘I’ll grab a snack and be back in five minutes,’ promised
Flanagan.
       ‘You’ll take forty-five minutes and like it,’ ordered Ryan.
       As Flanagan grinned wearily and went off Bill Duggan
said, ‘What about you, Leo, you look done in.’
       ‘Can’t leave you here all alone Bill, it’s a two-man job.’
       The technician, Chang, came in just in time to over-hear
him. ‘Some people have all the luck - the Commander just
nabbed me, said you needed some help. Of course, I’ve only
done two watches in a row!’
       ‘Congratulations,’ said Ryan drily. ‘I’ve just done three!’
       ‘Go on, Leo, clear off,’ said Bill Duggan. Chang and I
can handle things here.’
       Leo Ryan said, ‘I’ll just have a quick bite and - all right, I
know!’
       ‘You’ll take forty-five minutes and like it!’ said Chang
and Bill Duggan in chorus.
       Ryan grinned and went away. ‘Right,’ said Chang. ‘What
do I do?’

     The Doctor was studying another X-ray picture, not of a
Cybermat this time but of his own skull.
     ‘You may get the odd headache for a while,’ said
Gemma Corwyn. ‘But at least there’s no lasting damage. It’s
an extraordinary X-ray, though. In fact, your whole physical
make-up...’
      ‘I’m so glad there’s no damage,’ said the Doctor
hurriedly. ‘Well done, Miss Corwyn.’
      ‘It’s Mrs,’ said Gemma Corwyn quietly. ‘At least, it was.
My husband died three years ago in the asteroid belt.’
      ‘I’m so sorry,’ said the Doctor gently.
      ‘My name’s Gemma. Why don’t you call me that?’
      ‘Thank you, Gemma,’ said the Doctor solemnly. ‘Now,
tell me about your Commander, Mr Bennett. Isn’t he a
strange man to be in a position like this?’
      Gemma found herself torn between loyalty to Jarvis
Bennett and a desire to confide in the Doctor. ‘Well, not in
ordinary circumstances...’
      ‘Are there any ordinary circumstances in space?’
      ‘Jarvis simply can’t accept phenomena outside the
known laws of science...’
      The Doctor nodded. ‘I think that’s a very accurate - er...’
      ‘Diagnosis, you were going to say?’
      ‘You’re very perceptive, Gemma.’
      She looked anxiously at him. ‘You think Jarvis’s attitude
is a weakness - medically, I mean?’
      ‘Don’t you?’
      ‘Normally Jarvis is more than capable of commanding
the Wheel. It’s a continuous, merciless responsibility...’
      ‘Exactly! But what does a man like that do when faced
with a problem for which he doesn’t have a solution?’
      ‘I’ve been - concerned,’ said Gemma slowly. ‘I’ve a
feeling that there are some things that Jarvis just can’t face.
He may have blocked off a part of his mind...’
      Jarvis Bennett marched purposefully into the control
room, and stood surveying the technicians, working busily at
their consoles. ‘Everything going all right here? Yes, I can see
it is. Good, good. Well done!’ Nodding and smiling at
everyone who caught his eye, the Commander did a complete
circuit of the control room and disappeared out of the door.
      Tanya Lernov gave Casali a baffled look. ‘Enrico?’ He
looked up from his console. ‘Mmm?’
      ‘Did you notice anything - odd, about the Commander?’
      ‘No - why?’
      ‘He seemed a bit - detached.’
      ‘Yeah?’
      Tanya shrugged. ‘Probably just my imagination.’

      The Doctor was struggling into his coat when Jamie
came back into the room. ‘Well, here I am. Are you better
now, Doctor?’
      ‘He needs more rest,’ said Gemma. ‘You shouldn’t be up
and about yet, Doctor.’ She turned to Jamie. ‘Can’t you
persuade him to rest?’
      ‘Och, it’s no use trying to stop the Doctor doing what he
wants!’
      ‘Do be reasonable Gemma,’ said the Doctor. ‘I’ve got to
get up - I know the danger we’re in. The Cybermen want the
treasures of Earth, you see, they want to colonise...’
      ‘But you’re not even supposed to leave this room,
Doctor. Jarvis gave orders -’
      ‘He isn’t fully responsible!’
      ‘I’m sorry, Doctor. I can’t countermand the
Commander’s orders.’
      ‘But you let Jamie out.’
        ‘Only briefly. He’s got to stay here now - and so must
you.,
        Jamie grinned. ‘Hey, Doctor, she’s as stubborn as you
are.’
      The Doctor was about to protest further, when Jarvis
Bennett strode into the room. ‘Everything in order here?
Good, good. Up and about, eh, Doctor? I’ve done the tour,
Gemma, and everything’s running like clockwork!’
      ‘That’s fine, Jarvis. I think we ought to talk about the
rocket...’
      ‘Yes, yes, everything’s going well,’ said Jarvis. ‘You must
want to stretch your legs a bit, have a wander around.’
      The Doctor shot Gemma a quick look. ‘Er, yes, thank
you. You’ll tell the guard?’
      ‘Yes, I’ll deal with it.’ He opened the door and
addressed the bewildered guard. ‘Off you go, every-thing’s in
order!’ The guard moved away.
      ‘Jarvis!’ said Gemma sharply.
      He swung round. ‘Make a note about morale, Doctor
Corwyn. Never been better. Everything’s in order...’ His voice
tailed off. ‘Tired now, better turn in. Sleep, that’s the idea, I’ll
be needed at first watch...’ Reviving, he beamed at them.
‘Well, keep up the good work!’ With a cheery nod, Jarvis
Bennett turned and marched away, a happy man in a world
in which everything was in order.
      A world of his own.

     In the power room, Bill Duggan was gloomily
examining the handful of un-corroded Bernalium rods that
he’d been able to scrape together. ‘These are no good to us
anyway - they’re all covered in plastic.’
      ‘Didn’t anyone tell you?’ said Chang. ‘They brought
back a whole load of Bernalium from the rocket. It’s still in
the loading bay.’
      ‘Well, don’t just stand there, go and grab me half a
dozen rods. With a bit of luck we can have this lot
reassembled in a few more hours.’
      ‘On my way,’ said Chang, and hurried out.

       A few minutes later, Chang came down the steps to the
loading bay. The place was in semi-darkness. The crate from
the rocket stood in a little pool of light in the centre of the
bay. Chang went to the box, lifted the lid, and took one of the
boxes of Bernalium rod from the inside.
       Removing the box revealed the wooden surface of the
false top, and with a shock of astonishment, Chang realised
that the top layer of Bernalium was all there was. He took out
the rest of the boxes and then lifted out the false top,
revealing the empty blackness beneath.
       As he peered inside a giant silver hand reached out of
the shadows behind him, and gripped his shoulder, pulling
him back. Chang swung round, wrenching himself free and
staggered back against the crate. For a moment he stared up
in unbelieving horror at the giant silver form towering over
him. Then he snatched up one of the boxes of Bernalium
rods he’d just unpacked and hurled it at his attacker’s chest.
       The Cyberman staggered back, and Chang ran for the
stairs... A second Cyberman appeared out of the darkness,
blocking his escape. He turned, spun around - and saw
Laleham and Vallance come out of the shadows.
       ‘Help me!’ he screamed.
       But neither man moved or spoke. Chang turned again,
dodged round the Cyberman blocking his path and made a
desperate doomed run for the steps. The chest units of both
Cybermen glowed fiercely for a moment, and caught in the
fierce light Chang twisted, screamed briefly and died.
      One of the Cybermen walked to the foot of the stairs,
scooped up Chang’s body and carried it away, thrust almost
casually under one arm...
                           12
                      Into Danger
       Tanya Lernov glanced up as an indicator light came up
on a side-console. ‘Enrico, someone’s using the incinerator in
the loading bay. Have you got it down?’
       Casali punched up information on a read-out screen.
‘Nothing here.’
       Leo Ryan wandered in, looking fresh and rested.
‘What’s the problem, Tanya?’
       ‘Somebody just used the loading bay incinerator.’ ‘Looks
like a spot of unauthorised waste-disposal,’ said Casali. ‘Better
log it, Tanya. Someone’ll catch it...’

     Bill Duggan was hard at work reassembling the
capacitator bank when Laleham and Vallance came into the
power room. He looked up. ‘Hullo, boys. Where’s Chang?’
     Laleham said flatly. ‘He cut his hand. He has gone to the
medical bay.’
     Both men, Duggan saw, were carrying boxes of
Bernalium rods. ‘Trust him. Poor old Chang!’
     Vallance said, ‘What is to be done?’
     ‘Open a box of those rods will you?’ said Duggan. I’ve
nearly beaten this job. I only hope the rods are the right size.’
     ‘They are,’ said Laleham.
     Bill Duggan shot him a quick glance. ‘Didn’t know you
were an expert.’
     In the same toneless voice Laleham said, ‘The laser must
be made operative, or the meteorites will destroy the Wheel.’
      ‘No!’ said Bill Duggan sarcastically. ‘What do you think
I’m sweating over here for?’
      Laleham handed him a Bernalium rod. ‘It is the right
size.
      Duggan slotted the rod in place. ‘It is too! You must be
psychic. Better not tell the old man, he doesn’t believe in it.’
      ‘When will the repair be finished?’ asked Valiance.
      Bill Duggan was finding his two visitors a bit of a pain.
‘It won’t get done at all if you don’t stop nattering at me.’
      ‘The meteorites must not harm the Wheel,’ said
Valiance again.
      Bill Duggan returned to his work. ‘Worried about the
storm, are you? Well, don’t be. It’ll be a close thing, but I
reckon on having the laser assembled and ready for operation
in, oh, six or seven hours maximum.’ He looked up at them
and grinned. ‘So you two can sleep like babes, daddy won’t let
anything happen to you!’ Once again he bent over his work,
whistling tunelessly.
      Valiance walked over to the door and opened it. A
Cyberman came into the room.
      Still bent over his work Bill Duggan said, ‘Look, if you
two want to make yourself useful...’ He looked up, and saw
the Cyberman. Slowly he straightened up. He opened his
mouth to scream but a beam from the Cyberman’s helmet
transfixed him and he went rigid, staring straight ahead of
him - just like Laleham and Valiance.
      The Cyberman said, ‘The Wheel must be protected
from the meteorites. We will re-assemble your laser. You will
go to the control room. Here are your orders...’
       Gemma Corwyn was in her quarters, studying a medical
file on her computer read-out screen. The file was headed:
Jarvis Bennett.
       She looked up almost guiltily as someone came into the
room. Hurriedly she switched off the screen. ‘What is it, Zoe?’
       Zoe said worriedly. ‘It’s rather difficult... I’ve just made
a report, some calculations... I’ve been told to forget them.’
       ‘Ordered by whom? What report?’
       ‘My calculations on the path of the meteorite storm. I
found evidence of a critical state, reported it to the
Commander -’
       ‘And he ignored it?’
       Zoe nodded. ‘You don’t seem very surprised.’
       ‘He’s getting worse,’ said Gemma almost to herself.
       ‘Is he ill?’ asked Zoe.
       ‘I’m not sure, yet.’
       ‘If he is ill,’ said Zoe seriously, ‘he’s chosen a rather
inconvenient time, hasn’t he?’
       ‘Not very emotional, are you, Zoe?’
       ‘Emotional?’ Zoe frowned. ‘Leo Ryan said I was all brain
and no heart.’
       ‘It’s just your training, Zoe. I shouldn’t worry about it.’
       ‘Oh, but I do,’ said Zoe solemnly. ‘Don’t want to be a
freak. Maybe Leo’s right. My brain’s been pumped so full of
facts and figures... I want to feel things too.’
       Gemma Corwyn said gently, ‘Some people with your
training do have trouble developing their human emotions.’
       ‘You don’t think I’ll be like that, do you?’
       Gemma Corwyn smiled, ‘No, you appear to have
survived your brainwashing very well.’
       ‘Good,’ said Zoe.
      ‘Now then,’ said Gemma Corwyn. ‘Tell me about these
calculations of yours...’

      In the control room, the Doctor and Jamie, apparently
restored to favour were being given the tour.
      ‘... and this last one here is how we check all energy
expenditure,’ Tanya was saying. ‘Any device on the Wheel
that uses energy shows up somewhere on the board... from a
coffee grinder upwards.’
      ‘Have you got any coffee?’ asked the Doctor hopefully.
      Tanya shook her head. ‘I’ve got a coffee tablet - would
you like one?’
      The Doctor shook his head and wandered away. ‘You
won’t forget to keep an eye out for some mercury, Doctor,’
whispered Jamie.
      ‘I haven’t forgotten, Jamie. I’m very worried about the
TARDIS. If I’m right and there are Cybermen aboard that
rocket...’
      Zoe and Gemma hurried into the control room, and
were soon engaged in a low-voiced conference with Leo Ryan,
Tanya and Casali.
      The Doctor beckoned to Zoe, who came over to them.
      ‘What’s going on?’
      ‘I did some calculations on the meteorites - they’re
heading towards us faster than I’d first thought.’
      ‘Don’t you ever have any cheerful news?’ growled Jamie.
      ‘Facts are facts,’ said Zoe primly. ‘And these are
indisputable.’
      ‘I wouldn’t dream of arguing,’ said the Doctor
hurriedly. ‘Can you get the laser repaired in time?’
       ‘Apparently. The real worry’s the Commander. He just
brushed my warning about the meteorites aside. That’s the
worry, not the laser.’
       ‘He’s getting worse,’ muttered the Doctor.
       Zoe nodded. ‘That’s what Doctor Corwyn said. He is ill,
isn’t he?’
       Blatantly the Doctor changed the subject. ‘Why aren’t
you more worried about the laser? Even if you get it fixed in
time, I thought all the Bernalium had been destroyed.’
       ‘Oh no,’ said Zoe confidently. ‘Some more turned up.’
       ‘Oh good!’
       ‘Yes, two of the men brought a crate of it over from the
rocket.’
       ‘What did you say?’
       ‘That’s what Flanagan said - I met him coming off duty.’
       The Doctor went and grabbed Gemma Corwyn’s arm
and marched her away from the group. ‘Did you know about
this Bernalium from the rocket?’
       ‘Yes, Tanya told me just now.’
       ‘Don’t you see? The Cybermen came over in that crate!’
       ‘But our men wouldn’t have brought them across.’
       ‘Maybe they were tricked.’ The Doctor frowned. ‘Or
maybe they knew what they were doing. Cybermen have ways
of making people carry out orders.’
       ‘Hypnotism?’ asked Gemma.
       ‘Something like that.’
       ‘But all Wheel personnel are protected against brain
control. There’s an implanted Silenski capsule. It gives off a
signal if there’s any interference with the brain of the wearer.’
       ‘How can we check?’ asked the Doctor.
       Gemma led him over to Tanya. ‘I want to check the
Silenski circuit.’
       ‘I’ll have to activate the whole detection network.’
       ‘Do it,’ said Gemma. ‘I’ll authorise the extra power.’
       Tanya adjusted the controls and a large monitor screen
came to life, with a network of electronic trace-lines running
endlessly across it. ‘If the lines are even, everything’s normal...
I’ll scan this room first.’
       As Tanya began her check, Bill Duggan came into the
control room. He hovered uncertainly in the doorway.
       Jamie moved over to Zoe. ‘What’s he hanging round like
that for?’
       Zoe frowned. ‘I thought he was confined to quarters.’
She went over towards the door. ‘Hullo, Bill, has the
Commander...’
       Bill Duggan went on in to the control room, ignoring
her.
       The lines on Tanya’s scanner began fluctuating wildly.
‘Look!’
       ‘Someone is affected,’ said Gemma. ‘You were right,
Doctor!’
       ‘It’s someone in this room,’ whispered Tanya.
       ‘Can we pin it down?’ asked the Doctor quietly.
       ‘I’ll scan the room,’ said Tanya. She adjusted controls.
‘Somewhere over... that way...’
       She pointed - and they saw Bill Duggan raise a big
spanner high above his head and smash it down on the
communications console, again and again...
       ‘Stop him!’ yelled the Doctor.
       Jamie hurtled across the room and tried to pull Bill
away, but was thrown off with apparently superhuman
strength. The spanner smashed down again. Sparks crackled
across the console, and Casali was suddenly hurled backwards
out of his chair. As the spanner rose again, Leo Ryan drew his
blaster and fired... Bill Duggan crashed to the ground.
      The Doctor ran to the body and knelt to examine it.
‘He’s dead. The Cybermen must be here, on the Wheel. They
took over this poor fellow and sent him to stop you from
getting a message to Earth.’ He turned to Gemma. ‘If you’ll
take my advice, you’ll alert the whole Wheel. You’ll need
something to stop your people from being taken over. Small
sheets of metal will do, taped to the back of the neck. It
interferes with the Cyber control signal.’
      ‘I’ll see to it,’ said Leo Ryan, who had come to join them.
      ‘What do we do? asked Jamie.
      ‘We’re going hunting,’ said the Doctor grimly.
      ‘Oh aye? Are you sure you know who’s to be hunted?’
      The Doctor and Jamie moved off.
      Zoe watched them go. She shivered. ‘I feel cold, Doctor
Corwyn.’
      ‘It’s shock,’ said Gemma gently. ‘Just sit quietly and keep
out of the way.’
      Zoe sat down shivering. She had never felt more
frightened - or more useless.

     The Doctor and Jamie came down the steps into the
loading bay. The empty crate stood in its little pool of light.
     ‘Well, there it is,’ said Jamie.
     ‘Sssh,’ whispered the Doctor.
     They crept cautiously over to the crate. The loading bay
seemed to be empty. The Doctor and Jamie studied the crate,
working out the purpose of the false top. They saw the boxes
of Bernalium bars, stacked beside the crate. The only thing
they didn’t see was the giant silver form of the Cyberman as it
descended the steps behind them...
                        13
                  Cybermat Attack
      Suddenly Jamie heard the scrape of metal on metal,
turned round and saw the descending Cyberman.
      It was still at the top of the steps, staring arrogantly
straight ahead, and for the moment it didn’t seem to have
seen them. Jamie grabbed the Doctor by the arm and heaved
him out of sight behind the crate, and into the shadows
beyond. The Cyberman descended to the floor of the loading
bay, picked up one of the boxes of Bernalium rods, turned
and went back up the steps.
      As it disappeared, Jamie gave a silent whistle of relief.
‘That was close.’
      ‘I can’t understand them,’ said the Doctor. ‘It’s so easy
now.’
      ‘Eh? What are you talking about?’
      ‘Destroying the Wheel, Jamie. That’s what I’m talking
about. From the outside it’s strong enough, but now that the
Cybermen are inside...’
      ‘Aye, I see... What d’you think they’re planning then?’
      ‘I don’t know, Jamie, not yet - but it’s obvious that they
don’t want to destroy the Wheel.’
      ‘What do they want then?’
      ‘I wish I knew. But the first thing we must do is protect
these people.’
      ‘Aye, but how do we do that?’
      ‘What’s the one thing we need to survive that Cybermen
don’t?’
      ‘Food?’ suggested Jamie, thereby reminding himself he
was feeling peckish.
      ‘Always thinking of your stomach,’ said the Doctor
reprovingly. ‘No, air... that’s what, air!’ The Doctor rose and
went over to the wall communication unit. ‘Now, I wonder
how this works?’

      In the control room, Tanya called Gemma Corwyn and
Leo Ryan over to her console. ‘It’s the Doctor, calling from
the loading bay.’
      They saw the Doctor’s face on Tanya’s monitor. ‘It
would be wise to seal off all the airlock doors,’ he was saying.
‘Can you do that?’
      Tanya glanced at Leo, who nodded. She turned back to
the Doctor. ‘Yes, we can. Why?’
      ‘The Cybermen are definitely on the Wheel. Jamie and I
have just seen one. They may try to interfere with the air
supply.’

     ‘Doctor,’ whispered Jamie.
     ‘Yes, what is it?’
     Jamie pointed. ‘I think I saw something move, over
there in the shadows. I just caught a glimpse of it in the
corner of my eye.’
     The Doctor turned, peering into the shadows.

       ‘What’s wrong?’ asked Gemma.
       Tanya said, ‘I don’t know.’
       ‘Shall I seal off the airlock doors, Gemma?’ asked Leo.
       Gemma considered for a moment, then nodded. ‘Yes,
do it.’
      Leo went over to another console and began issuing
instructions. Tanya looked up at Gemma Corwyn and said
quietly, ‘I suppose we can trust the Doctor?’
      ‘I’m not sure why I do, but I do,’ said Gemma. ‘Anyway,
sealing off the airlocks is good common sense.’

       Jamie pointed again. ‘There, look!’
       The Doctor saw a Cybermat, gliding from a patch of
shadow into the light. It didn’t appear to have seen them as
yet... The Doctor turned back to the intercom, speaking in an
urgent whisper. ‘Listen to me very carefully. Please, just do as
I ask and don’t delay. There’s a Cybermat very close to us.
Any moment it’ll tune into our brainwaves...’
       Jamie had been keeping the Cybermat under
observation. ‘It’s turning, Doctor,’ he whispered. ‘And look,
there’s another!’
       The Doctor whispered into the wall mike. ‘Hook up a
vario audio-frequency to this channel - at once please!’

     Tanya looked at Gemma for a decision.
     ‘Do it please, Enrico,’ she ordered.
     Casali began making rapid adjustments of a console.
They heard the Doctor’s voice. ‘Hurry! Please hurry!’ ‘Come
on, Enrico,’ pleaded Gemma.
     Casali flipped a switch. ‘That’s it - power on.’ They
heard a low, oscillating electronic howl.

     In the loading bay the sound was coming from the
communications mike which the Doctor had deliberately left
swinging from its wall fitting.
     The Cybermats began gliding forwards.
       The Doctor and Jamie retreated slowly towards the
steps...
       ‘Come on, let’s run for it!’ urged Jamie.
       The Doctor shook his head. ‘They’ve got a range of at
least ten feet...’
       The Cybermats made a sudden dart forwards, as if to
attack. But the move brought them within range of the sound
from the dangling wall mike... Suddenly they began swinging
to and fro in erratic curves, like disorientated dodgem cars.
Their paths intersected and they collided with a metallic
crash. For a moment they were still, then one began zooming
round in circles while the second sped straight for the wall.
The circling Cybermat began giving out smoke, ground slowly
to a halt and expired in a final puff of smoke. The second
Cybermat smashed into the bulkhead and blew up,
disappearing in smoke and flame.

       In the control room the Doctor appeared on the
monitor, waving his hands. ‘That’s quite enough, thank you!’
       Casali switched off the electronic howl.
       The Doctor ducked down then popped up again with
the defunct Cybermat displayed on a box lid. ‘This is what
you saved us from!’
       Tanya peered at it unbelievingly. ‘What is it?’
       Zoe, who had been looking on silently all this time said,
‘It’s a Cybermat.’
       ‘Exactly,’ said the Doctor. ‘We’re coming back as soon as
we can.’
       As the Doctor’s face vanished from the screen, a light
began flashing on a nearby console.
       ‘Leo?’ called Tanya.
      He came across to her, and she indicated the light. ‘It
seems to be a signal from the power room.’
      Leo studied the indicator light, puzzled. ‘Yeah - and it
doesn’t seem to be coming from our power source. Let’s check
it out...’

      In the power room a Cyberman was operating a Cyber-
Communications Unit, reporting to the Planner. ‘The
Cybermats have been destroyed.’
      ‘By what method?’
      ‘By the use of high-current phase contrast.’
      ‘Some human has knowledge beyond our prediction.
Continue report.’
      ‘The laser-cannon is now repaired and operative.’ ‘And
the communication beam to Earth?’
      ‘Attacked and damaged.’
      The Planner said, ‘Excellent. Phase Six will now be
completed. The Wheel is to be taken over.’

      Enrico Casali looked down at the shattered
communication beam console, shaking his head. ‘Bill Duggan
knew the spots to attack all right. What a mess!’
      ‘How about radar?’ asked Tanya.
      ‘That’s okay. But the Earth communication circuits are
done for.’
      ‘What time’s the next check with Earth Central?’
      ‘Two hours time.’
      ‘Better set up a fix on the first wave of the meteorites.’
      Casali shrugged. ‘Doesn’t seem much point, not without
a laser to knock them away with.’
      ‘Don’t be a pessimist, Enrico. They may not hold on a
crash course to us. Anything can happen.’
     Casali grinned. ‘Everything has!’
     Leo Ryan looked up his face concerned. ‘I’ve been
checking the different sections on the intercom.’
     Tanya looked puzzled. ‘And?’
     ‘I can’t raise anyone...’ He looked worriedly at her. ‘We
might be alone on the Wheel.’
                          14
                     Meteor Storm
      Tanya’s eyes widened in alarm. ‘Have you told Gemma
Corwyn?’
      ‘Not yet. I reckon she’s got enough on her plate. I’ll go
on checking...’
      On the other side of the control room Jarvis Bennett
was sitting in his command chair, with Gemma, Zoe, Jamie
and the Doctor grouped around him. Gemma had persuaded
him to leave his quarters for the control room in the hope that
familiar surroundings might help to restore him to normality,
but it wasn’t working. Jarvis Bennett’s earlier euphoric mood
had faded, and he was slumped down in the chair a picture of
depression while Zoe held a lifeless Cybermat up in front of
him.
      ‘Jarvis, look at it,’ pleaded the Doctor. ‘Bring it forward,
Zoe, into his line of sight.’
      Zoe held the Cybermat directly in front of the
Commander’s face. Jarvis Bennett’s eyes widened. He began
shivering, and twisted his head away. ‘No... it’s not true... not
true...’
      Gemma Corwyn said, ‘All right, Zoe, put that thing away
somewhere.’ She looked at the Doctor. ‘It looks like complete
withdrawal.’
      ‘Not necessarily complete,’ said the Doctor. ‘Catatonic
features, certainly.’
      ‘I could try E.C.T.... maybe he could be shocked back to
normal.’
      ‘Give him a little more time,’ said the Doctor. ‘You’ve
thrown a force-field around this section - strong enough to
keep the Cybermen out?’
      ‘Strong enough to keep anything out!’ She looked
worriedly at Jarvis, who was staring gloomily at the ground.
      ‘It’s no good, Gemma,’ said the Doctor gently. ‘You’re
the second in command - you’ll have to take over.’
      ‘Take over what?’ asked Gemma bitterly. ‘We’ve been
invaded, we’ve no contact with Earth, and we’re in the path of
a storm of meteorites, and we can’t fight them off because
there’s no laser!’
      Zoe took the Cybermat over to Jamie, and put it down
on top of a console. Jamie nodded towards Jarvis. ‘How is he?’
      ‘Hopeless, he’s just closed himself away. Doctor
Corwyn’s second in command - I suppose she’ll take over.
Though what she can do... or any of us, for that matter. I feel
so useless, Jamie.’
      Jamie patted her clumsily on the shoulder. ‘You’re just
not trained for this sort of emergency.’
      ‘That’s the whole point! What good am I? I’ve been
created for a false kind of existence where there are only
known emergencies. What good is that to me now?’
      ‘Hey, we’re not done yet, you know,’ said Jamie. ‘We’ll
survive this mess yet!’
      Zoe didn’t look convinced.
      Leo Ryan was still going on with his check. ‘Section
twelve? Make contact section twelve!’
      There was no reply.

     Section twelve was the oxygen supply room. There was
no answer to Leo Ryan’s call because the duty technician lay
dead on the floor, a Cyberman towering over him.
      Flanagan came into the power room, and looked
around, surprised to find it empty. The wall communications
unit was buzzing and he went to answer it.
      Suddenly Valiance appeared from around the side of a
storage locker and stepped forward, barring his way.
      ‘So there you are,’ said Flanagan. ‘Why don’t you
answer that thing, someone sounds a bit violent.’
      Valiance said flatly, ‘It is not important.’
      ‘It could be the old man himself, for all you know!’
      Laleham stepped out from behind another storage
locker.
      Suddenly Flanagan noticed that the capacitator bank for
the laser-cannon, which he had last seen in numerous pieces,
seemed to have been reassembled as good as new. ‘Is the laser
working again?’
      Laleham said, ‘The repair is finished.’ He spoke in the
same flat tone as Valiance.
      ‘So we’re not to be riddled by meteorites after all then?
Sure that’s a relief, and me with a whole year’s Earth leave
due!’
      The Intercom was still buzzing, and instinctively
Flanagan went to answer it again, and again Valiance barred
his way. ‘Do not touch that.’
      ‘You can’t just ignore it!’ To Flanagan’s utter
astonishment, Valiance drew his blaster. ‘Have you gone
mad?’ demanded Flanagan.
      Valiance said, ‘Do as you are told.’
      Contemptuously Flanagan swept the blaster aside.
‘What’s the matter with you, boy?’ He gave Valiance a shove
that sent him staggering back.
      Laleham too drew his blaster.
      Flanagan promptly knocked it out of his hand, and
knocked Laleham down for good measure. Flanagan backed
away, raising his fists. ‘All right, come on! If it’s a fight you’re
after, I’m your man. Come on both of you!’ Flanagan was a
big powerful man, and an accomplished brawler.
      Laleham and Valiance, their reflexes dulled by
Cyberman control were just no match for him.
      Valiance came forward, aiming a clumsy blow, and
Flanagan side-stepped and knocked him down with scientific
precision.
      Laleham scrambled to his feet and rushed at him, a
heavy spanner in his hand. The spanner swept towards
Flanagan’s head, Flanagan dodged aside, and the spanner
smashed into a metal bench with a force that jarred it from
Laleham’s grasp.
      Now thoroughly enraged, Flanagan grabbed Laleham
and began shaking him to and fro. ‘Now that wasn’t sporting!
You want a few lessons in the Noble and Manly Art, me
friend.’
      Shaking his head, Valiance scrambled over to his fallen
blaster, snatched it up, and got to his feet, aiming the weapon
at Flanagan’s back. He fired... Just as Laleham, in a frantic
effort to break free from Flanagan’s grip, twisted himself
around - and stumbled full into the path of the blaster bolt.
      Laleham staggered and fell dead to the ground.
      Flanagan and Valiance stood motionless for a moment,
Flanagan shocked out of his fighting fury, Valiance shaken
free of the Cyberman’s control.
      ‘You’ve killed him!’ gasped Flanagan.
      Valiance stared at him, too shocked to speak. Then his
eyes widened as he stared over Flanagan’s shoulder, and his
body went rigid.
      Flanagan swung round, and saw the giant silver form of
a Cyberman looming over him.
      Before Flanagan could move or speak, he was transfixed
by the beam from the Cyberman’s helmet. His body went
rigid, and he stood passive, waiting.
      The Cyberman spoke. ‘The laser has been repaired?’
      Valiance bowed his head. ‘Yes.’
      ‘A force field is in operation around the control room.
How is it operated?’
      ‘From within the control room itself.’
      The Cyberman glanced down at Laleham’s body.
‘Dispose of this human.’ It turned and stalked away.
      Obediently, Flanagan and Valiance lifted Laleham’s
body...

      Zoe was feeding Jarvis Bennett water from a beaker. He
took a sip or two, then turned his head away like a sulky child.
‘No more...’
      ‘Just give him what he wants,’ said Gemma.
      She went to join the Doctor and Jamie, who were
grouped around Casali who was operating the radar screen.
      ‘They’re coming through now.’
      A whooshing, humming sound was coming from the
radar complex. ‘It’s a big one,’ said Casali. ‘Even bigger than
we thought.’
      ‘All right, all right, don’t make it worse,’ said Leo Ryan
nervously.
      Gemma said, ‘We’ve still got the anti-matter field
projectors.’
      ‘You don’t think meteorites like this are going to bounce
off that, do you?’ said Casali. ‘We’re talking about things
weighing two or three hundred tons here!’ He adjusted his
screen and suddenly they could see a swarm of blips,
travelling across the screen. ‘There they are - swarms of them
- and they’re headed straight for this Wheel!’
                         15
                  Poison in the Air
      There was a moment’s awed silence.
      ‘How far away are they?’ Gemma Corwyn asked.
      Casali studied his instruments. ‘Under a million miles,
now. Closing in on an elliptical path, tilted ten degrees.’
      As yet, the danger wasn’t imminent. But it was
unavoidable.
      Suddenly there came a buzz from the communication-
unit, and Flanagan’s face appeared on screen. ‘Power room
here.’
      ‘Flanagan! Where have you been?’ said Leo Ryan
explosively.
      ‘We have been repairing the laser capacitator bank.
Work has now been completed.’
      Leo Ryan was too excited to register Flanagan’s flat
voice and stilted manner. ‘Are you telling me the laser’s
working again?’
      ‘Ready for testing.’
      Leo swung round to the others. ‘Hear that? The laser’s
repaired! Stand by to run a test.’ He turned back to the
screen. ‘Why didn’t you answer me, Flanagan? I’ve been
calling for ages!’
      ‘There must be a fault on the line,’ said Flanagan in the
same dull voice. ‘Valiance is with me. We’re ready when you
are.’
      Gemma, the Doctor, Jamie and Zoe stood watching as
Leo and his team ran through a series of checks. ‘What’s the
range of this thing?’ asked the Doctor. ‘Fifty-thousand miles
for total destruction, ninety for partial,’ said Gemma.
        ‘Hmm... won’t do to miss any, will it?’
        ‘Some of the forerunners will be in range now. We can
use them to test. We’ll try a random shot,’ said Leo. ‘At least
it’ll tell us how the power bank reacts. Blue control.’
        Casali said, ‘Red on standby. Angle eighty-eight to zero
four zero one. Distance closing, five four nine, four eight...
zero!’
        ‘Fire!’ said Ryan. ‘Tanya give me a power reading.’
        ‘Power normal at maximum. Meteor has been
destroyed.’
        Leo Ryan sat back satisfied. It had been just one shot,
one meteor destroyed out of untold numbers... But steering
and power had responded perfectly. Leo Ryan said
cheerfully, ‘Well, everybody, I think we stand a chance.’

      It was some time later. The Control room was humming
with activity. More and more of the meteorites were coming in
range now and Leo and Tanya and the rest of their team were
steadily deflecting or destroying them.
      Against the steady background of information, orders
and reports the Doctor and Gemma were talking quietly.
      ‘I think it’s safe to assume that the Cybermen caused this
meteor storm,’ said the Doctor. ‘They must have made the
star go nova.’
      ‘Why?’ asked Gemma. ‘To destroy the Wheel?’
      ‘No, they just wanted to make you use the laser. The
Cybermats were sent in to attack the laser, by ruining the
Bernalium.’
      ‘Aye, that’s right,’ said Jamie. ‘Then you’d be sure to
search that drifting rocket, find the crate and bring it on
board - with Cybermen hidden inside!’
      The Doctor nodded. ‘It was all a cunning plan to get on
to the Wheel.’
      Gemma said, ‘And you really think it was the Cybermen
who repaired the laser?’
      ‘They had to,’ said Jamie, ‘or the Wheel would have
been smashed up!’
      ‘This isn’t just an attack on the Wheel,’ said the Doctor.
‘The Cybermen have an overriding ambition to invade Earth
and plunder its mineral wealth. Somehow they must be able
to see a way of doing that through this Wheel...’ The Doctor
began patting his pockets. ‘Jamie, the Time Vector Generator
- where is it?’
      ‘You’ve got it. I put it back in your pocket when we were
on board the rocket.’
      ‘But I haven’t got it!’
      ‘It must have fallen out of your pocket, just before they
brought you across. Is it important?’
      ‘Important?’ spluttered the Doctor. ‘It’s vital! Someone
will have to go over to the rocket and find it.’
      ‘Well, good luck to them whoever they are! Who’s
going?’
      ‘Well, Jamie, if Doctor Corwyn can spare someone to
help you make the crossing - you are!’
      ‘Me?’
      ‘You’re the only one besides me who knows what to look
for, and I’m needed here. Besides, it’s your fault it’s lost!’

     In the power room the Cyberman was making a further
report to the Planner. ‘The meteorite shower is now
approaching the Wheel. The weapons of the humans have
been tested and are operative.’
      ‘Phase Six can now be completed.’
      ‘The humans have set up a force field barrier around
the section containing their control room.’
      The Planner said, ‘To complete Phase Six it will be
necessary to initiate plan three.’
      The Cyberman switched off the communicator and
turned to Vallance, who had been waiting silently in the
corner. ‘Follow me.’

       Jamie, Zoe and Gemma Corwyn stood waiting at a
corridor junction. The air before them seemed mildly hazy.
Looking through it, things on the far side looked blurred, and
if you tried to walk through you would have been held
motionless. Gemma looked at her watch, and suddenly the
haze vanished. Gemma hurried across the junction,
motioning Jamie and Zoe to follow her.
       On the far side, she picked up a wall communicator.
‘Replace the force field barrier - we’re through.’
       Zoe said, ‘I’ll check that it’s clear ahead.’ She moved on
a little.
       ‘Don’t see what you’ve landed me with her for,’
grumbled Jamie.
       ‘She knows enough space drill to get you across to the
rocket - and she’s the only one I can spare.’
       ‘I still think I’d do better by myself!’
       Gemma smiled. ‘Do you? Don’t be too sure.’

     Meanwhile in the control room, Leo Ryan and the
Doctor were having a furious row about the same subject.
      ‘Zoe agreed to go,’ said the Doctor obstinately. ‘She’d no
right to agree - and you’d no right to ask her.’
      ‘It had to be done. Jamie will look after her.’
      ‘Have you any idea what it could be like between the
Wheel and that rocket. The whole area’s bound to be
bombarded with debris...’
      ‘They know the risks,’ said the Doctor quietly. ‘Zoe
calculated them.’
      ‘And what about Gemma? She’ll have to make her way
back here on her own.’ He glared at the Doctor. ‘From now
on you don’t do anything without checking with me first,
OK?’ He glared angrily at the Doctor, and the Doctor scowled
mutinously back at him.
      ‘Meteorite coming in range - now!’ called Casali.
      Leo went back to his console.

     The route to the airlock led through the oxygen supply
room - and there Gemma and her party had stumbled on the
body of the dead technician.
     Shocked, Gemma knelt to examine the body. ‘Is he
dead?’ whispered Jamie.
     Gemma straightened up. ‘I’m afraid so. Zoe, the
emergency exit.’ She led the way to a hatch in the wall and
opened it. ‘That’ll take you to the air-lock. You’ll find space
equipment in the supply locker.’
     ‘Right, come on, Jamie,’ said Zoe. She clambered into
the dark space, and Jamie scrambled after her.
     ‘Good luck,’ said Gemma as she closed the hatch behind
them. Crossing over to the wall unit she called the control
room. ‘They’ll be away any minute. Shouldn’t be any
problems.’
     In the control room, Casali called, ‘This is the main
concentration... coming into range now.’
     ‘Crossover on vector link,’ said Ryan. ‘Countdown as
from now...’
     They bent tensely over their instruments.

      Out in deep-space the massive meteor swarm was still
hurtling swiftly and silently towards them. Hundreds of
meteors had been deflected or destroyed, but there were
hundreds more to come. It would only take one to destroy the
Wheel and everyone on it.

      Gemma Corwyn was about to set off back to the control
room when she heard movement in the corridor and ducked
into hiding behind an instrument console.
      A Cyberman stalked into the room, Valiance behind
him. The Cyberman surveyed the oxygen room. ‘Each section
of the Wheel has its own oxygen supply?’
      ‘Yes,’ said Valiance.
      The Cyberman handed him a metal container, which
held rows of silver capsules. ‘Insert one capsule into the
supply for each section. The oxygen will turn into pure ozone
and the humans will die...’

       ‘Fire!’ commanded Ryan. Another meteorite exploded
in space.
       ‘We’re hitting them,’ called Casali. z ut there are so
many... It’s hopeless.’
       ‘Shut up,’ snapped Ryan, hunched over his console.
‘Fire!’
       Suddenly the monitor screen came to life and Gemma’s
face appeared. ‘Gemma Corwyn to control room.’
     The Doctor, the only one not fully occupied, leaned
forward. ‘Yes, Gemma, what is it?’
     ‘The Cybermen are going to poison the air supply. Do
you understand? Tell Leo Ryan to switch over to the
emergency sectional supply units. Do you understand?’
     The Doctor peered into the monitor. Gemma was
looking not at the screen but at something just behind her.
‘How do you know, Gemma?’ called the Doctor. ‘What’s
happening there? You must get back here right away.’
     The screen went blank.

      Hanging up the mike, Gemma Corwyn turned to face
the giant silver form that was looming over her. The
communication unit had been in a corner some way from
Valiance and the Cyberman. She knew that she would be
heard - but she also knew that the call must be made.
      Drawing her hand blaster, Gemma trained it on the
Cyberman and fired. It stopped, staggered back, then
continued its remorseless advance. Before she could fire
again, the Cyberman’s chest unit glowed fiercely, and Gemma
twisted and fell.

      Jamie and Zoe, space-suited and steering with their
oxygen packs, were over half way to the rocket when the
fringe of the meteorite storm reached them. Jamie saw it first.
‘Zoe, look!’
      It was an astonishing, terrifying sight; the debris of a
shattered star, chunks of rock the size of golf balls, footballs,
others as big as a house, and icebergs, some very like small
mountains.
      Jamie heard Zoe’s voice sounding inside his space
helmet. ‘It’s the meteorites, Jamie - and they’re heading
straight for us!’
                         16
                  Perilous Journey
      ‘Fire!’ shouted Leo Ryan.
      Somewhere a meteorite, heading for the Wheel,
exploded in smoke and flame.
      ‘We’re still hitting them!’ said Casali grimly.
      ‘What about Jamie and Zoe?’ asked the Doctor. ‘They’re
out there too you know.’
      Tanya said, ‘They’ll be in danger from shock, from
radiation and blast...’
      ‘They’ll have to take their chances,’ said Leo savagely. ‘I
can’t think about anything except stopping those meteorites.’
He returned his attention to the firing console. ‘Fire!’
      Tanya looked up at the Doctor. ‘They’ll be blown out of
space!’
      ‘Zoe calculated the risks,’ said the Doctor. ‘Let’s hope
she was right!’

     Explosions all around them, holding hands in an
attempt to keep together, Jamie and Zoe cartwheeled through
space, flung to and fro by the explosions all around them.
     A final, violent explosion very close to them blasted
them apart and they spun off in different directions...

     ‘The radar screen’s clear,’ said Casali. ‘We’ve done it!’
     ‘Any sign of Jamie and Zoe?’ asked the Doctor anxiously.
     ‘Can’t pick ’em up on screen till all the static’s cleared.’
      ‘We’ll stay on Blue stand-by for the moment,’ said Leo.
‘There’ll be a cloud of small stuff following behind. Check all
circuits, maintain power levels till further notice.’
      Leo Ryan rose and stretched, glanced curiously at Jarvis
Bennett, who was still slumped motionless in his chair, and
went over to the Doctor. ‘You realise what you’ve done,
Doctor? Those two kids have probably been either burnt up
by radiation, or fried by thermal blast - always assuming they
weren’t actually hit by all that rubbish.’
      ‘Do you think I’m not aware of that?’ said the Doctor
bitterly. ‘It was a calculated risk - one which had to be taken.’
      ‘Why?’
      ‘Because there’s something on board the rocket we need
if we’re to defeat the Cybermen.’
      ‘Something that justified risking two lives?’
      ‘In order to save many - yes. Incidentally, we’ll all die
very soon unless you switch over to sectional emergency air
supply.’
      ‘What?’
      ‘The Cybermen are planning to poison your air.’
      Leo Ryan stared at him. ‘How do you know?’
      ‘Gemma Corwyn told me.’
      ‘Where is she?’
      ‘In the oxygen room but -’
      ‘I want to talk to her.’ Ryan headed for the
communicator.
      ‘I’m afraid you can’t,’ said the Doctor sadly. ‘She’s dead.’
      Leo Ryan went and punched up a picture of the oxygen
room on the monitor. It showed a section of floor, with the
lower part of Gemma Corwyn’s crumpled body.
      ‘She sacrificed herself to warn us,’ said the Doctor.
      Casali looked up from his radar screen. ‘Here comes the
following wave!’
      ‘Right,’ said Leo. ‘We’ll try three second interval shots,
but we’ll reinforce the anti-matter shield around the Wheel as
well. Maybe we can deflect some of this lighter stuff off course.
Tanya, switch over to sectional emergency air supply.’
      The rattle of readings, instructions and commands filled
the control room once more as the second wave of meteorites
were either deflected or destroyed.
      Suddenly the Doctor said, ‘Where’s Jarvis?’ The
Commander’s chair was empty.

      Jarvis Bennett marched purposefully along the
corridors, away from the control room. He had lost his former
apathy and looked determined, even exalted.

      Tanya was flicking the monitor screen through various
channels in an attempt to locate him when the communicator
screen lit up, showing Jarvis Bennett’s face.
      ‘Jarvis, what are you doing?’ called Ryan. ‘You must
come back!’
      ‘No, I’m going on,’ said Jarvis calmly. ‘They killed
Gemma, you know. I lifted the force field to get out - you’d
better replace it right away.’
      Leo Ryan rose and headed for the door, but the Doctor
caught his arm. ‘Where are you going?’ ‘To fetch Jarvis back.’
      ‘I’m afraid it’s already too late for that. Look!’ The
Doctor pointed to the monitor.
      They saw Jarvis turn away from the screen and move off
down the corridor - straight towards an approaching
Cyberman.
      Jarvis Bennett smiled, as if pleased to come face to face
with his enemy. He drew his blaster and fired, blast after blast
at the approaching Cyberman - but to no effect. Hurling the
weapon at the Cyberman Jarvis Bennett closed with it, in an
attempt to wrestle it to the ground.
      His action was as suicidal as it was brave.
      The Cyberman caught and held him in an inflexible
steel grip, simply ignoring his attempt to attack. It raised him
high above its head then smashed him to the ground. Even
then, Jarvis wouldn’t give up.
      As he struggled feebly to rise, the Cyberman’s chest unit
glowed fiercely and caught in the killing beam, Jarvis’s body
writhed and twisted grotesquely for a moment, then fell back,
dead.
      The Cyberman stepped over the body and moved on. In
the control room a horrified audience watched his death
struggle on the monitor.
      Tanya turned away. ‘Please, turn it off...’
      The Doctor flicked the control and the screen went
blank.

      Jamie had good reason to be grateful for Zoe’s brief bit
of space training. Somehow he’d managed to brake himself
with his air jet then steer himself over to the rocket, where he
found Zoe just about to enter the airlock. Now they were both
on board the rocket, feeling somewhat astonished to be alive.
      Jamie was fetching Zoe some water from the dispenser.
      ‘Thanks, Jamie,’ she said, sipping it gratefully.
      Jamie looked at her in concern. ‘How do you feel?’
      ‘I really didn’t think we were going to get through,’ she
said. ‘I feel as if someone’s been hitting me all over with
hammers!’
      ‘Take it easy while I look round.’
      Zoe got up. ‘No I’ll help.’ She looked round the control
room. ‘What is it that we’re looking for?’
      Jamie held his hands apart. ‘It’s a rod, about so big, with
black and gold tips to it. Come on then, let’s start looking.’

      The Cyberman said, ‘You have inserted the capsules
into the air supply unit?’
      ‘Yes,’ said Vallance dully.
      ‘Inject it into the system.’
      Vallance operated a lever and there was a hiss of air.
The Cyberman said, ‘Effective penetration should be
immediate. Report!’
      Valiance studied the oxygen room instrument dials.
‘They have already switched over to the emergency supply.’
      ‘Can that be reached?’
      ‘No. The controls are inside the force field.’
      The Cyberman hesitated - then called up the Planner on
the Cyberman communication unit.
      The eerie transparent head appeared on the little
screen, ‘Do you report success?’
      ‘No. Our plans have been anticipated.’
      ‘Wait. The Data will be re-computed.’ There was a high-
pitched electronic twittering and symbols flowed across the
screen.
      The Planner reappeared. ‘One of the Earthmen must
have experience of our method. Projection of all identities on
the Wheel is essential...’

       Jamie found the missing rod in the corridor, just outside
the little cabin. He came hurrying back into the control room.
‘Here it is, Zoe, I found it. We can go back now -’
     Zoe waved him to silence. After a perfunctory search of
the control room she had started fiddling with the
communication equipment - with very unexpected results.
     On a monitor screen, Jamie could see one of the Wheel
technicians, a Cyberman beside him, using some kind of
communication device.
     ‘Come and look, Jamie,’ said Zoe excitedly. ‘This could
be important. I seem to have broken in on the Cyberman
frequency...’
                           17
                      The Invasion
      ‘Stare into the device,’ ordered the Cyberman. The light
on its helmet glowed gently.
      Vallance obeyed.
      The Cyberman said, ‘Now think of each individual
human on the Wheel. Form the image in your mind.’
      The Cyberman Planner sat staring straight ahead,
concentrating on the images that appeared in con-junction
with Vallance’s voice.
      ‘Tanya Lernov. Astrologer, second class.’ A young, fair-
haired human female.
      ‘Negative,’ said the Planner.
      ‘Leo Ryan, Communications Officer.’ A large human
male.
      ‘Negative.’
      ‘Jarvis Bennett, Station Commander.’ An older human.
      ‘Negative.’
      ‘Zoe Heriot, Astrophysicist, Astrometricist, first class.’ A
small human female.
      ‘Negative.’

       ‘That’s me,’ said Zoe. ‘They seem to be running through
all the crew of the Wheel, one after the other.’
       ‘But why?’ said Jamie wonderingly. ‘What are they
after?’
       The figure of a small male dark humanoid appeared,
and for the first time Vallance’s voice faltered. ‘Doctor... The
Doctor... I don’t know his name.’
     ‘Repeat image,’ ordered the Planner. ‘Concentrate!’

      In the control room a conference was in progress. ‘But
what possible use could these Cybermen have for the Wheel,
Doctor?’ Leo Ryan was asking.
      ‘That remains to be seen,’ said the Doctor infuriatingly.
      ‘Why shouldn’t they simply be attacking us?’
      ‘Why would they go to all this trouble just to knock out
one space station?’
      Tanya interrupted them. ‘Leo, there’s something on
radar.’
      The Doctor and Leo went over to the radar screen. ‘Not
a meteorite,’ said Casali. ‘Look, it’s changing course.’
      ‘No ships are due in this sector of space,’ said Tanya,
checking her log.
      Casali said, ‘Too big for one of ours anyway.’
      ‘It could be a Cyberman ship,’ said the Doctor quietly.
‘Moving in for the kill?’ suggested Leo.
      ‘Possibly.’
      Leo turned to Casali. ‘What about the Earth
communication system, Enrico? We must try to contact Earth
for assistance.’
      ‘Not a chance,’ said Casali. ‘Oh, I could repair it all
right, given time, but I’d need some valve transistors and
some replacement circuitry, and they’re all in the power
room.’
      ‘Then someone will have to go and get them,’ said Leo.

      ‘Positive,’ said the Planner. ‘Positive; the Doctor is
known and recorded as an enemy of the Cybermen. He must
be lured outside the force field and destroyed.’
      In the rocket control room, Jamie leaned forward and
switched off the scanner. ‘They’re going to try and trap the
Doctor. We must get back and warn him.’
      They began putting on their space helmets.

      The Doctor, Tanya and Leo Ryan were poring over a
map of the Wheel.
      ‘This is the route to the power room,’ said Tanya,
tracing the corridors with her forefinger.
      Leo Ryan frowned. ‘Trouble is, we don’t know where
the Cybermen will be - the direct route’s no good.’
      ‘Well, how else will you get there. Through the cable
tunnels?’ He shook his head. ‘They’re blocked off - here and
here. That leaves the emergency air tunnels...’
      They were interrupted by the buzz of the
communicator, and turned to find Flanagan’s face on the
screen.
      ‘Flanagan, where are you?’ said Ryan.
      ‘In a corridor near the workshops. I’ve got a whole
bunch of them locked up in a workshop.’
      ‘Well done, Flanagan! Is the way to the power room
clear?’
      ‘It is for now. But they’re trying to melt down the doors,
I may not be able to hold them for much longer.’
      ‘Well try to keep them bottled up as long as possible,’
said Ryan. ‘One of us has to come through for some radio
spares.’
      ‘Right, I’ll seal off some more compartments, sir. But
you’d better send someone for those spares pretty quickly.
They may be trying the other doors.’
      ‘Tell him I’ll go for the spares,’ whispered the Doctor.
      ‘It’s better if I go,’ said Ryan. ‘I know just where -’
      ‘It’s essential that I go,’ insisted the Doctor.
      Ryan shrugged. ‘All right, Doctor, it’s your neck.’ He
turned back to the intercom. ‘Flanagan, the Doctor’s coming
for the spares. Hold the Cybermen back as long as you can.’
      ‘Right, sir. I’ll meet the Doctor in corridor six.’ The
screen went blank.
      The Doctor took Ryan aside. ‘When Flanagan turns up
here, let him in through the force field - then grab him!’
      Tanya said, ‘But he isn’t coming here. He said he’d meet
you in corridor six.’
      The Doctor smiled. ‘I don’t think so.’ He picked up the
map. ‘Now don’t forget, don’t trust him. Check the safety
plate on his neck. Turn off the force field so I can get out will
you? Oh, and tell me where the spares are, will you?’
      Ryan told him, and the Doctor hurried away.

      In corridor six, Flanagan stood stiffly before a
Cyberman. ‘The Doctor will come here, to corridor six.’
      ‘Excellent. You will return to the control room. Once
they have admitted you, you must destroy the machinery that
sets up the force field.’
      Flanagan turned and moved away.

        It was dark and eerie in the deserted power room. A
grille moved in the wall, and the cover was lifted off from
inside. The Doctor clambered down into the room and looked
around. Following Ryan’s directions, he located a shelf of
spares above a workbench, and filled his pockets with the vital
equipment. On a nearby shelf he found a phial of mercury.
Beaming delightedly he stowed it away in a separate pocket.
On his way out, the Doctor paused by the main work bench,
still cluttered with odds and ends after the repair of the laser
capacitator. Some Bernalium rods, coils of wire, connectors
and plugs - and a handy power point nearby...
      ‘Yes, I think so,’ said the Doctor. ‘Worth a try!’ Picking
up a coil of wire he set to work...

      Zoe and Jamie had a much calmer journey from the
rocket to the Wheel. They reached the airlock without
incident, and returned to the oxygen room through the same
hatchway by which they’d left it. They slipped out of the door
and moved off down the corridor. Suddenly a massive figure
stepped out of a side corridor.
      Zoe looked up at him. ‘Flanagan!’
      ‘And what are you doing wandering about? Don’t you
know them creatures is everywhere? You two come with me
now, this way’s quicker.’
      He led them off down the side corridor.

      Not far away, in corridor six the Cyberman turned to
Valiance. ‘The Doctor has not come.’
      ‘He must have gone another way. There’s an air tunnel
leading to the power room.’
      ‘Show me,’ ordered the Cyberman.
      They moved away.
      The Planner’s orders had to be obeyed - the Doctor
must be found and destroyed.

     In the control room, Ryan and Casali were waiting, one
each side of the door. Tanya stood waiting too, a blaster in her
hand. They were waiting for Flanagan.
     Just as the Doctor predicted, Flanagan had called in on
a communicator and asked them to let down the force field so
that he could come into the control room. He was bringing
Jamie and Zoe with him.
      The door opened, and Flanagan came in.
      Ryan and Casali jumped him. They wrestled him to the
ground, face down, and Tanya passed Leo one of the Doctor’s
improvised metal plates to clamp on his neck.
      Jamie and Zoe, who had followed Flanagan in, looked
on appalled.
      ‘What are you doing?’ demanded Zoe. ‘He helped us, he
guided us back here.’
      ‘He’s controlled by the Cybermen,’ said Tanya.
      Ryan finally managed to get the metal plate fixed to the
back of Flanagan’s head. He bucked and reared wildly for a
few moments, and then lay still. After a moment he groaned,
clutching his head.
      Ryan got to his feet, still panting. ‘He’ll be all right now.
Let’s get him sat down, Enrico.’ Between them they got
Flanagan into a chair.

     Jamie looked round. ‘Where’s the Doctor? We
overheard the Cybermen planning to lure him into a trap.’
     Tanya said, ‘But he’s already -’ She was interrupted by
the buzz of the communicator.
     The Doctor’s face appeared on screen. ‘I’ve got the
spares.’
     Jamie hurried over. ‘Doctor!’
     ‘Jamie! Are you and Zoe all right?’
     ‘Aye, we’re fine. Listen, Doctor, the Cybermen know
you’re on the Wheel. They’re planning to trap you.’
     ‘Yes, I thought they might. Jamie, did you find the Time
Vector Generator?’
     ‘I have it right here, Doctor.’
      ‘Just bring it to me, would you Jamie? Get someone to
show you the way through the air tunnels. I’m afraid I’m
expecting visitors.’
      The screen went blank.
      ‘Visitors?’ Jamie frowned. ‘What does he mean -
visitors?’

       The Doctor made a final connection to the power box
and straightened up. He had built up a structure of
Bernalium rods on either side of the door, and both were
connected by cables to the power box. His work was finished,
just in time.
       A Cyberman was standing in the doorway.
       ‘Oh, are you waiting for me?’ asked the Doctor politely.
       ‘You are the Doctor? You know our ways.’
       ‘Yes, I thought you’d realise that someone did, sooner
or later,’ said the Doctor modestly. ‘I imagine you have orders
to destroy me?’
       ‘Yes,’ said the Cyberman.
       The Second Cyberman appeared beside the first.
       ‘Tell me,’ said the Doctor conversationally. ‘Why did you
make Duggan destroy the radio communication beam to
Earth. That is why you want the Wheel, isn’t it? As a way to
reach Earth?’
       ‘He was instructed to destroy only the transmitting
complex.’
       ‘Of course,’ said the Doctor. ‘How interesting. I suppose
your giant Cyber-ship holds your invasion fleet, and the
smaller ships inside need the guidance of a radio beam from
Earth?’
       ‘You know our ways,’ repeated the Cyberman. ‘You are
to be destroyed.’
      ‘Yes, I thought we’d get back to that sooner or later. Do
come in!’
      The Cyberman stepped into the doorway.
      The Doctor stooped down and threw the power switch.
Electricity crackled between the two sets of Bernalium rods.
Caught in the powerful force field the Cyberman writhed and
twisted in a sort of grotesque dance - a dance of death. Smoke
poured from its helmet and chest unit and suddenly the
Cyberman went rigid and crashed to the ground like a felled
tree. The second Cyberman’s chest unit glowed - but the
Doctor’s electric force-field repelled the deadly ray.
      ‘It’s no good you know,’ said the Doctor calmly. ‘You
can’t break through the field.’
      ‘Others are coming, Doctor,’ said the Cyberman
threateningly. ‘You will be destroyed.’ It backed slowly away,
disappearing down the corridor.
      The Doctor heard a sound and spun round. The grille
was being lifted away from inside. A moment later, Jamie
appeared, followed by Flanagan.
      ‘Ah, Jamie,’ said the Doctor happily. He looked
suspiciously at Flanagan. ‘Is he all right now?’
      ‘Aye, he’s fine,’ said Jamie. ‘Aren’t you, Mr Flanagan?’
      ‘Except for a head like a big base drum I am,’ growled
Flanagan. ‘And somebody’s going to pay for it.’
      Jamie looked down at the dead Cyberman. ‘Looks as if
you’ve made one pay already, Doctor.’
      ‘Yes, but they’re sending in re-inforcements, Jamie.
Probably through the loading bay. Just give me the Time
Vector Generator, will you?’
      Jamie handed it over.
      ‘I’m going to try to fix this into the laser gun circuitry,’
explained the Doctor. ‘With luck it’ll boost the power energy
to destroy the Cyber-ship. You’ll have to hold them off at the
loading bay for me - I need time!’
      ‘Leave it to me,’ said Flanagan.
      ‘There’s still one Cyberman left on the Wheel,’ warned
the Doctor. ‘You’ll have to deal with him first.’ He fished in
his pocket. ‘Oh, and here’s a protective plate for Vallance
when you find him.’
      ‘Right, sir,’ said Flanagan taking it. He grabbed a can of
spray plastic from a shelf. ‘Let’s see how them creatures like
this! Well, come on Jamie, let’s be at them!’
      Flanagan and Jamie hurried off, and the Doctor headed
for the laser gun capacitator bank.
      The final stage of the Cyberman invasion was about to
begin.
                     18
            An End and a Beginning
       Casali looked up from the radar scanner. ‘That ship’s
moving closer. It’s colossal!’
       Ryan was talking to the Doctor over the intercom.
       ‘I’m trying to put more power into your laser,’ said the
Doctor. ‘Line the cannon on the Cyberman space ship and I’ll
tell you when I’m ready.’
       ‘You’d better be ready soon,’ said Ryan. ‘That ship’s on
the move.’
       ‘I know,’ said the Doctor. ‘They’re planning to invade
the Wheel.’

     Flanagan marched Jamie into the loading bay, both of
them now wearing space suits. Vallance, also space suited
stood waiting, and beside him was the waiting Cyberman.
     ‘I couldn’t get into the power room for the force field,’
explained Flanagan. ‘I caught this feller on the way back.’
     ‘He is not important,’ said the Cyberman. ‘Guard him.
He may be useful later.’
     Luckily the Cyberman had a lot to worry about, thought
Jamie. They all stood, waiting.

      The Doctor was working rapidly on the laser bank,
trying to find a way of building in the Time Vector Generator
without blowing the whole installation.
      Ryan was watching him on the intercom. ‘Hurry,
Doctor. That ship’s still moving in!’
      In the loading bay the Cyberman moved towards the
door controls.
      ‘Now,’ yelled Flanagan.
      Jamie leaped on Valiance, bearing him to the ground,
trying to clamp the metal plate Flanagan had given him onto
the man’s neck. Valiance stuggled furiously...
      As the Cyberman turned, Flanagan brought up the
plastic gun and emptied it into the Cyberman’s chest unit.
The Cyberman staggered back choking. Smoke began
pouring from its helmet. It reeled back, collapsing - but
before it fell, it managed to press the button that opened the
loading bay doors. The doors slid back onto the blackness of
space.
      Jamie managed to clamp the metal plate to the back of
Vallance’s neck - and the man went limp. Struggling to his
feet, Jamie looked out through the opening doors and
gasped.
      The horizon was filled by the colossal bulk of the Cyber-
ship, now incredibly close. And from the ship there was
streaming an army of Cybermen, jetting towards them
through space.
      Flanagan ran to the control, and the doors began to
close. But not quickly enough. The leading Cybermen were
almost on them now, and the first managed to jam itself in the
doors before they were quite closed. Incredibly, its strength
was such that it could stop the doors from closing.
      With limitless others to help, the Cybermen would be
able to wrench the doors open again, Jamie realised. ‘Use the
plastic!’ he yelled.
      He heard Flanagan’s frantic voice inside his helmet.
‘Can’t... emptied it onto the other one...’
      Through the gap, Jamie could see more Cybermen
arriving to aid the first.

      In the control room, the laser-cannon was aligned on
the colossal Cyber-ship - the ship that held the invasion fleet
destined for Earth. They were waiting for the Doctor now.
      His voice came over the intercom. ‘Right, everything’s
ready here!’
      ‘Fire,’ yelled Leo Ryan.

     A beam of extraordinarily intense light shot from the
Wheel’s boosted laser cannon, striking the Cyber-ship at point
blank range. The ship was bathed in a fierce glow of light -
and exploded in smoke and flame.

       The glare lit up the loading bay like lightning.
       The Cyber-ship might be gone, thought Jamie - but they
still had swarms of angry Cybermen, clustering around like
wasps - and any moment now they’d be inside.
       Flanagan had opened up a panel in the wall, and was
throwing switches. ‘I’m going to operate the neutron field
barrier. Hold on!’ He threw the last switch and the loading
bay, and indeed the whole of the exterior of the Wheel
hummed with power.
       The force field was designed to repel the smaller
meteorites - but it repelled Cybermen as well.
       Shot off from the Wheel, they spun away into the
blackness of space, cartwheeling away into infinity.
       The door closed and Flanagan touched the control that
flooded air back into the loading bay.
       ‘We’ve done it!’ gasped Jamie, and sank exhausted to
the ground.
      ‘Wheel to Earth control,’ said Casali. ‘Stand by for
emergency report.’ He looked round. ‘Where’s Zoe, by the
way?’
      ‘Taking the Doctor and Jamie back to the rocket,’ said
Tanya.
      A voice from the speaker said, ‘Earth Control standing
by. Report.’
      Leo Ryan drew a deep breath. ‘This is Leo Ryan, Acting
Commander of Station Three. Radio contact with Earth lost at
1252 hours, due to attack by alien force...’
      Leo became aware of Tanya’s cool hand removing the
protective metal plate from his neck.
      He caught one of her hands and held it as he poured
out the incredible story of recent events on the Wheel in
space...

      Jamie and Zoe were standing in the control room of the
rocket.
      ‘So you’ve really got to go back?’ said Zoe.
      Jamie nodded awkwardly. ‘I’m afraid so.’
      ‘You won’t tell me anything about this TARDIS of yours
- Time and Relative Dimensions in Space—that’s what the
Doctor said it meant. But you won’t explain it?’
      ‘Look, it’s like... well, like two different worlds. You have
yours, and we have ours.’ Jamie thought of the shock it had
been for him to leave his own place and time, and of how
sometimes his heart still ached for his native highlands. He
heard the Doctor calling him.
      ‘Look, Zoe,’ he said, ‘You’ve been - well, we won’t forget
you.’ He turned and hurried away, leaving Zoe staring after
him.
       The Doctor meanwhile had been having a very busy
time. He had replaced the Time Vector Generator, restoring
the TARDIS to its normal size. Normal, for the TARDIS that
is, since it was once again bigger on the inside than the
outside. Now he was topping up the mercury level once again,
pouring the mercury he’d found on the Wheel into the
TARDIS console by means of an old tin kitchen funnel. He
looked up as Jamie came in.
       ‘All set, Doctor?’ asked Jamie.
       ‘Yes, I’ve even got a little mercury left over.’
       ‘Then we can go?’ Jamie seemed to be in a hurry - as if
leaving was a wrench and he wanted to get it over with.
       Over Jamie’s shoulder, the Doctor watched amusedly as
Zoe crawled into the TARDIS on her hands and knees, and
climbed inside an ornate wooden chest he kept in the control
room for its decorative value.
       ‘There’s just one little matter to settle first, Jamie,’ said
the Doctor gently. He went over to the chest and opened the
lid. Zoe climbed shamefacedly out.
       ‘Hey, I told you -’ began Jamie.
       Zoe said firmly. ‘I want to go with you!’
       ‘Well, ye canna’. It’s impossible.’
       ‘Not impossible, Jamie,’ said the Doctor. ‘What we have
to decide is - is it wise? You might be sorry one day, Zoe, wish
you’d changed your mind.’
       ‘I won’t.’
       The Doctor smiled. ‘I wonder.’ He opened a panel in
the TARDIS console, and took out a kind of headset. He fitted
it on and settled himself in a chair. ‘Look at that screen up
there...’
       Jamie was baffled. ‘What are you going to do, Doctor?’
       ‘I’m going to show Zoe the sort of thing she might be in
for, if she stays.’
       Zoe looked at the headset and at the screen. ‘Thought
patterns, Doctor?’
       ‘Yes. I shall make them into a complete story... Have
you ever heard of the Daleks, Zoe?’
       ‘No.’
       ‘Then watch,’ said the Doctor impressively.
       Shapes began to appear on the screen, squat menacing
metallic shapes.
       The Daleks...
       Jamie realised that the Doctor was telling Zoe the story
of one of their recent adventures, the one in which they’d first
met poor Victoria.
       Jamie wondered if she was happy in her new life. He
hoped so. Curiously, he was finding it hard to remember her
face - especially with Zoe’s vivid little face gazing enthralled at
the screen. Jamie noticed something else.
       Consciously or unconsciously, the Doctor must have
operated the controls before sitting down. The TARDIS doors
were closed and the centre column was rising and falling. The
TARDIS was already in flight.
       Jamie hoped Zoe wouldn’t be too scared by the Doctor’s
Dalek story. Because now, like it or not, she was on her way.
