Out of the transparent plastic came a smell which certainly was very like roast chicken. But Victoria didn't fancy it somehow.

'Thank you,' she said politely. 'I'm not so hungry now,' she said primly. 'I would like something to drink.'

Kaftan reached into the aluminium box and took out a vacuum flask.

'Perhaps you will pa.s.s me the other rucksack,' she said.

Then, as Victoria walked over to fetch it, Kaftan quickly poured out a cup of coffee, took a small tube out of her pocket and tipped a white tablet into the cup. Victoria returned hugging the rucksack.

'You are cold-yes?' said Kaftan kindly as Victoria shivered and nodded. 'This will warm us both up,' said Kaftan, handing her a cup of coffee. Everything about the lovely Arab woman was now warm, friendly and even motherly towards Victoria. She took the coffee and cupped her hands round its comforting warmth.

'Here is to success in their search,' said Kaftan, raising her own cup and drinking it like a toast.

If the two women had not been so preoccupied with their drinks they might have noticed that Victoria's handbag had moved two inches from its position on the bench.

Inside, the long dormant Cybermat was beginning to come to life.

The men meanwhile had climbed down the long ladder and were a.s.sembled at the foot of the wall. Ahead, the pa.s.sageway, a.s.sembled in sections like a subway tunnel, sloping down into the interior of the planet.

As the Professor shone his flashlight ahead of them, the walls reflected back a million tiny diamond-like particles of frost rime. He stamped his feet impatiently as the Doctor and Toberman climbed down beside him.

'Hurry up,' he said, 'we've no time to linger. It's extremely cold here. Even with these anoraks.'

Jamie looked over at Klieg who was wearing his own expensive fleece-lined jacket. ' You You obviously knew what to expect,' obviously knew what to expect,'

he said.

Klieg gave a half-smile that was more like a sneer. 'I always come prepared,' he said insultingly, glancing at the Scot's bare knees below his kilt.

'Which way do we go?' asked Viner vaguely, looking along the tunnel both ways.

'Hardly back upwards,' said Parry, indicating the upward sloping tunnel. 'Let's try this one.' And decisively he strode along the downward pa.s.sage. The others followed, their boots crunching on the powdered ice on the floor. The corridor was cut as straight as a Roman road, no difficulties such as hard rocks or underground streams could stand in the way of a race as efficient and ruthless as the Cybermen.

'Ah! It seems we are arriving,' said the Professor.

As the men followed the Professor out of the tunnel, they found themselves inside a huge, cathedral-like cavern.

As the Professor's flashlight beam crept upwards they could see that, built against the rock surface, was a huge edifice that, at first sight, resembled a vast honeycomb.

The far wall was covered with a structure composed of hexagonal units, one neatly fitting into the other like the cells in a beehive. The surface of each cell was covered with a thin membrane, heavily coated with h.o.a.r-frost.

The Professor shone the torch downwards and around the cavern. Beside the entrance there was a control desk, similar to the ones in the surface rooms, but there seemed to be no further extension of the tunnel beyond the room.

'It seems we've reached a dead end.' The Professor was tired and disappointed. 'There are no Cybertombs here. We shall have to try the other tunnel.'

The rest of the party, except for the impa.s.sive Toberman, Klieg, who was examining the control board with his torch, and the Doctor, also voiced their disappointment.

'This will be our tomb, if we don't get back up to the surface,'

Viner snorted.

'Wait,' said the Doctor, 'if I may borrow your flashlight.' He turned to the Professor and walked over to the lower row of hexagonal cells.

'Here,' he called. Viner, Jamie and the Professor, struck by the note of excitement in his voice, walked over to him, as he put the torch against the side of the thin, white membrane.

The light illuminated the inside of the cell. Clearly visible inside was a hunched, humanoid figure curled up in an embryonic posture with its head on its knees.

'I think you've found your tombs, Professor.' The Doctor handed his torch to Parry and stepped back as the others cl.u.s.tered around, amazed.

'It is-the Cybermen!'

The large silver helmet was plainly visible now, as the Professor shone his torch to and fro, around the surface of the cell.

'Here's another.' Viner pointed to the next cell where a similar figure was crouched. The. huge cavern seemed to be taking power from their torches and, as in the tunnel, the metal held the light and reflected, it back, gradually illuminating the whole vast honeycomb.

Klieg left the control board and strolled over to join them- apparently as unaffected by the general excitement as the stolid Toberman.

'You don't seem surprised, Mr Klieg,' said the Doctors 'You obviously knew what to expect.'

'Perhaps,' said Klieg. His eyes seemed to hold a different kind of excitement to the others, inner, triumphant.

The Professor, almost in tears, was shaking hands with Viner as the other congratulated him.

'Forgive me,' he said to the Doctor and Klieg. 'But, after so many years of work... and such. a long search...'

Jamie had been examining one of the Cybermen through the membrane. He turned to the Doctor.' 'They didna' look dead, or even damaged.'

'They're not,' said the Doctor. 'They are in a state of hibernation. All their power for evil is locked up in this ice. And so they must remain,' he added, almost to himself.

'Like bees. in a gigantic honeycomb waiting for the signal to arise from their winter sleep,' said Klieg.

'A signal they are never going to get,' said the Doctor sharply.'

But Klieg merely smiled his superior closed smile, and walked back to study the control board.

Viner, his fears returning as the euphoria of the great discovery wore off, blew into his hands to warm them. 'We had better get busy, Professor. Everything must be recorded.' He took a notebook from his pocket.

'Eh,' said the Professor, jolted out of his reverie. 'Yes, of course. Inconsiderate of me. We must get busy. It's far too cold to stay here for long.'

'Unless we can find a way of warming things up,' Klieg called over his shoulder.

The Doctor, looking suspiciously over at him, saw that he was laughing quietly to himself; as though he had made a joke. The Doctor wondered again about the secret motives of Klieg and Kaftan in financing and coming on this trip. Neither seemed really interested in the pleasures and satisfactions of archaeology. With a slight stab of apprehension, he wondered how Victoria was coping, left alone with Kaftan. He had trusted to the girl's quick intelligence, but had he failed to put her on her guard with the woman?

Victoria was not feeling either quick or intelligent. She was overpowered with sleepiness. Whenever she opened her eyes, the room seemed too bright for her, so it was easier to shut them. Why was she so sleepy, she wondered drowsily. All the strain, she supposed. But she'd stayed up here because the Doctor was worried about something. There was something she should be on her guard against... something... her head fell forward on to her chest.

'You have hardly touched your coffee,' said Kaftan's concerned voice. 'It must be cold by now. Here, I will give you some more.'

Why does she keep on about the coffee, wondered Victoria, half inside the place of sleep.

'No thanks,' said Victoria. 'I feel much warmer now.'

'That is good.'

'I just feel sleepy,' murmured Victoria and then gave in. Her head settled back against the table and she relaxed into a full sleep.

Kaftan waited a moment, then went over to look at her. Yes, the girl was breathing the deep slow breaths of sleep, her head on her arms, her hair flowing on the table. Without wasting a moment more, she went straight to the control console, looked at it for a moment, pressed the levers and b.u.t.tons, and taking a notebook from her pocket, pressed a sequence of b.u.t.tons.

Below the gears of the hatch were engaged, and as she watched, the great metal lid creaked slowly down from its upright position, until it slammed shut with a clang that echoed down the icy blackness of the shaft.

What was that?'

Viner, whose fear made his ears sharp as a bat's, lifted his head as the distant sound of the slamming hatch echoed as a m.u.f.fled thump, along the metal corridor.

'It sounded like...'

The Doctor, Jamie, Viner and the Professor turned and listened with dread as the vibrations trembled into silence.

'It's the hatch,' said Jamie.

Only Klieg and Toberman seemed unworried. They exchanged quick glances. The Professor, his camera busy at the far end of the vault, seemed unconscious of the situation. Jamie, followed by Viner, turned and rushed along the frozen tunnel towards the entrance well, slipping and sc.r.a.ping on the ice-covered metal floor. It seemed longer now, an unrelenting climb. They got to the shaft, gasping for breath, their lungs hurting with the cold, and gazed up. Above them there was no friendly circle of light, only the faint phosph.o.r.escence of the shaft walls.

'It's closed!' shouted Jamie, his voice cracking.

He started up the ladder, his fear making the larger-than-man-sized gaps between each rung hardly noticeable. He must get it open.

But as he climbed he remembered the heavy sound of the gears. No one with human strength could open that great metal hatch and he knew it.

Viner had started on the bottom rung of the ladder, but halfway up its icy gaps filled him with the fear of falling. He gazed upwards, panicking.

'What's the use?' he called to Jamie, who was still climbing.

'We're trapped down here, now. We'll never survive in this cold.'

Jamie ignored him and climbed on. 'Better get back,' Viner added to himself. Let Jamie look after himself, he thought.

He climbed down the ladder and ran back along the tunnel.

'Well?' said the Doctor, as Viner re-entered the vast cavern.

'It's closed,' said Viner gasping for breath. 'What have they done that for?' he added shakily. 'What are they playing at?'

'Perhaps it wasn't them,' said the Doctor. Viner looked at him with growing horror.

'Where's Jamie?' asked the Doctor.

'He went up the ladder to try it.'

Viner rushed over to the Professor who was still calmly photographing the glittering tiers of Cybertombs. 'Professor-' he began.

The Professor waved him to silence as he crouched for the perfect shot. These pictures, he could see them already, beamed on to the viewing screens of half the universe-'Professor Parry Discovers the Lost Tombs of the Cybermen'...

'Professor, listen to me, for Heaven's sake!' squawked Viner, jabbing him in the shoulder and spoiling his angled close-up shot of a tomb. 'The hatch is down. The hatch hatch is is down down, Professor. We're trapped down here.'

Realising the situation at last, the Professor straightened up.

'Eh? Trapped ? Are you sure ?' He looked at the little scientist. 'But there are some of my party up there.'

'Of course I'm sure,' snapped Viner. 'You know how heavy that thing is. It's down now.'

He looked round him and as he looked, the ice seemed to creep closer.

'We must do something. I'll give us a couple of hours in here at the most!'

Professor Parry looked confused. He looked around uncertainly. Klieg was still standing at the control console, not bothering to join in the conversation, and Toberman stood next to him, as if waiting for a command.

'Mr Klieg doesn't seem too worried,' said the Doctor.

'No,' said Klieg over his shoulder. 'No, Doctor. I'm not.'

Jamie ran back in. 'It's nae good,' he said. 'Stuck fast! I can't make anyone hear.'

'You see,' said Viner, in an I-told-you-so voice.

But the others were looking at Klieg. He alone seemed unshaken by their plight-filled with a new a.s.surance. He turned.
