Part 17 (1/2)

The others started awake.

'Eh-' said Jamie.

'What... what is it?' said Victoria.

Callum was still sleeping heavily, a difficult person to wake.

The Cybermat, its antennae tense with the proximity of human flesh, nudged cold against his foot, crawled nearer, and like a spider, ran up his body to his chest, its antennae pointing straight at his skull- homing in on his brain waves..

'Callum! Callum!' shouted the Doctor.

Callum grunted and started to wake up.

'Those terrible things again!' said Victoria.

Callum was awake now, staring down at the silver machine p.r.i.c.kling up across his chest..

'DON'T MOVE!' said the Doctor, willing Callum to obey.

Callum froze as the creature swarmed up his chest, he could feel the antennae buzzing towards his head, the red eyes flas.h.i.+ng in his face, already he felt a dizziness...

The Doctor edged nearer and nearer... Callum. didn't move.

With a sudden jerk the Doctor whipped the Cybermat off Callum's shoulder.

The creature fell on its silver segmented back and like a fallen hedgehog, couldn't get its balance for a moment, its side legs trying to get purchase on the ground.

'Quick,' said the Doctor. 'All of you. Get over this side of the room. Don't make any sudden movements.'

They backed away slowly. Parry was still drowsy: he stumbled and fell over one of the rucksacks.

'Steady, steady,' said the Doctor, and Parry, seeing the Cybermats, pulled his body away, got up carefully and crept with the others to the controls side of the room. 'Now, don't panic,' said the Doctor in a firm quiet voice. 'We'll go to the Cyber-recharging room and shut them out.'

They backed away towards the door of the recharging room.

Victoria was first, the nearest to the door. Suddenly she turned and screamed.

The others looked back: there were three more Cybermats, silver, segmented, squirming, progressing towards them with a faint buzzing, their antennae pointed at the humans' brains.

'Let's get out to the surface,' said Callum. 'Main doors-'

They took two steps, three steps, they were nearly there, when in through the pa.s.sage to the main door came three more creeping Cybermats.

'Doctor!' cried Victoria.. 'We're trapped!'

The nine Cybermats now communicated with each other, in a series of small high-pitched bleeps. Their antennae moved towards each other as if they were co-ordinating some plan.

'Back there to the controls, everyone,' said the Doctor.

The Doctor and Parry backed to the control panel, and for a moment, the forward movement of the Cybermats stopped. They seemed undecided about which direction their victims had taken. The Doctor, pressed back against the control panel, looked around, thinking what he could do with the available weapons, control panel, lever, b.u.t.tons, metal bars, stool, electrical cables...

'Quick, give me a hand,' he said to the Professor. He looked at the control board for a moment-and turned off a power switch.

Then whipping a pair of clippers out of his roomy pocket, he grabbed a length of the stout cable running between the two parts of the control console.

He cut the cable free of the wall and started laying it down on the ground between them and the Cybermats, like a magic circle.

Parry caught on fast, yanked down more cable and helped him.

The Doctor cut the other end of the cable free and jammed the two ends into two power sockets on the underside of the console.

'Stand back!' shouted the Doctor.

But Callum had drawn his gun and was outside the cable.

'Let's blast the filthy things,' he shouted, still shaken from the feel of the creature on his chest. He fired three times.

One of the Cybermats, knocked over on to its side, curled up like. a leaf in a fire, crackled, burst into smoke and the red eyes'

lights went out. But the others crawled on, their antennae like missiles pointing with deadly accuracy.

'You're wasting your time,' said the Doctor. 'You can't kill them all with that. Do as I say. Come back here. Keep close to us.'

Callum turned and stepped back into the half circle of the cable. Towards the cable advanced the Cybermats, bleeping to each other, their antennae pointed, slowly and relentlessly.

The Doctor turned on the power. A spark seemed to arc along the cable from the tremendous voltage. The first three Cybermats swerved and skittered erratically around, travelling in circles, until they crashed into one another.

'There we are!' shouted the Doctor. 'The current will destroy them.'

The bleeping rose to a new high as if the small dynamos of the Cybermats were burning themselves out.

'What are those creatures?'.asked Professor Parry, scientific curiosity again uppermost.

They looked at the metal crustaceans, now completely disorientated, running in repeated circles, and, one by one, curling up, their segments crackling apart with the current.

The last Cybermat turned over, smoke rising from its casing, its silver legs stiffening, as the machine burnt out: 'How did you do it, Doctor?' Jamie said. It was all beyond his comprehension.
