Luchov shook his head. 'That still won't get them back,' he said.

'Not yet, not now,' Khuv grated, losing his patience. 'But if there is a way back we'll find it. Even if it means building another Perchorsk!'

Luchov took a pace backwards, was brought up short when the small of his back met the handrail. 'Another Per - ?' His jaw fell open. 'Why, I hadn't even considered - '

'I didn't think you had, Direktor.' Now Khuv grinned, his face a grim, emotionless mask. 'So now consider it. And stop worrying about these men. If you must worry, then worry for yourself, and for your staff. You'll find that in those orders, too. Once the bridgehead is established - you're next!'

Luchov tottered where he stood grasping the rail. He was furious, but shock had made him impotent as Khuv turned away. Then he found his voice, called out: 'But oh how neatly you've escaped the net yourself, eh, Major?'

Khuv paused, slowly turned to face him. He was as pale as Luchov had ever seen him. 'No,' he shook his head, and Luchov saw his Adam's apple working, 'for that, too, is in the orders. You'll be happy to know that in just ten days' time we part company, Viktor. For when they go through, I go with them!'

At the other end of the shaft to the magmass levels, out of sight round the corner, Vasily Agursky had been privy to all their conversation. Now, as Khuv's footsteps sounded on the boards, he turned and ran silently for the upper levels. He wore rubber-soled shoes, moved with the litheness of a cat. No, like a wolf! He loped, and revelled in the strength of his thighs as they effortlessly propelled him. Strong? Even in his youth he'd never known such strength! Nor such passions, desires, hungers...

But for all Agursky's speed and stealth, still Khuv caught a glimpse of him before he could pass out of sight. It was only that, a glimpse, but it caused the KGB Major to frown. On top of all his other worries, now there was this thing with Agursky - whatever it was. Khuv hadn't seen much of him lately, but whenever he had ... he couldn't put his finger on it but something was wrong. And there he went, swift as a deer, head forward, silent as a ghost and just as weird.

Khuv shook his head and wondered what was ailing the strange little scientist. Wondered what had got into him ...

The next morning, early, Khuv jerked awake to the clamour of alarms. In the moment of waking his heart almost stopped - tried to tear itself free and leap up into his throat - until he realized that these were only the general alert alarms, not Luchov's damned failsafe. Thank God - whom Khuv didn't really have any faith in, anyway -for that!

A moment later, as he hurriedly dressed, came the hammering on his door. He opened it to let in the unctuous Paul Savinkov; except that apart from the sweat on his fat, shining, frightened face, there was nothing at all slimy about him now. He smelled now not of grease but fear!

'Major!' he gasped. 'Comrade! My God, my God.r

Khuv shook him. 'What is it, man?' he snarled. 'Here, sit down before you fall down.' He shoved Savinkov into a chair.

The fat esper was trembling, wobbling like a jelly. 'I... I'm sorry,' he said. 'It's just... just...'

Khuv slapped him, backhanded him, deliberately slapped him again. 'Now perhaps you'll tell me what's wrong!' he growled.

The white burn of Khuv's slim fingers came up like long blisters on Savinkov's face. His eyes lost their glaze and he shook his head, as if he was the one who had just woken up and not Khuv. Then - Khuv thought the man was about to burst into tears. If he did, Khuv knew he would hit him right in the teeth! 'Well?' he rasped.

'It's Roborov and Rublev,' Savinkov gasped. 'Dead, both of them!'

'What?' Khuv knew he must be imagining this; it had to be some crazy dream. 'Dead? How, for the love of - ? An accident?' He finished dressing, slipped into his shoes.

'Accident?' Savinkov grinned like an idiot, but his features quickly melted into a sob. 'Oh, no - no, it wasn't an accident. When it happened, their thoughts woke me up. Their thoughts were - awful!'

Thoughts?' Khuv's mind, still not fully awake, sought for an explanation. Of course: Savinkov was a telepath. 'What about their thoughts?' -v

'Something... something was attacking them. In Roborov's room. I think they'd been playing cards, gambling, and that Roborov was a heavy loser. He'd been to the toilet. When he came out... Rublev was nearly dead! Something had him by the throat! Roborov tried to pull it off, and ... it turned on him! Oh, God - 1 felt him die! Huh... huh... he...'

'Go on, man!' Khuv gasped.

'He grabbed the thing and turned it around, and he saw it. He was thinking: "I don't believe this! Oh, mother, help me! Sweet God, you know I've always loved you! Don't let this happen!"'

'Those were his thoughts?'

'Yes,' Savinkov sobbed. 'The rest of it was just background stuff, but it was Roborov's thoughts that really woke me up. And as he died - I saw it too.r

'What did you see?' Khuv took Savinkov's face between the flats of his palms.

'God, I don't know! It wasn't human - or maybe it was? It was a nightmare. It was ... its shape was all wrong! It was like... like that thing in the glass tank!'

Khuv's blood ran cold. He gulped air into his lungs, released Savinkov's face. He grabbed his lapels and dragged him to his feet. 'Take me there,' he snapped. 'Roborov's room? I know it. Were you there? No? Then who is there? You don't know? Fool! Well, we're going there right now!'

On their way, the alarms stopped clamouring. 'Well, let's be thankful for that, anyway,' Khuv grunted. He jostled Savinkov ahead of him. 'At least I can hear myself think! Now, are you sure you can't remember who you told? I mean, did you simply forget all the procedures and come running straight to me? God, but if this is a wild-goose chase I'll -!'

But it wasn't.

Outside the door of Roborov's room a sleepy, nervous soldier stood on guard. He saluted sloppily as Khuv and Savinkov came into view. They rushed by him. Inside were two more espers, and a KGB man named Gustav Litve. All were whey-faced, shaken to their roots. Crumpled on the floor, there lay the reason. Or reasons.

Nikolai Rublev could be Savinkov's twin! thought Khuv, grimacing at what he saw. They were, or had been, much of a kind. But now there were differences, the main one being that Savinkov was still alive. And he was also intact.

Whatever it was that had killed Rublev, it had taken half his face from him. The fleshy part of the left side of his face was missing, flensed from the bone, from his ear to his nose and down to his chin. But it wasn't the work of a scalpel or knife. The flesh had been ripped off. In addition his throat was torn - torn, as by an animal - with the main arteries severed and exposed. Khuv thought: where's all the blood?

Perhaps he'd said something out loud, for his underling Litve said: 'Sir?'

'Eh?' Khuv looked up. 'Oh, nothing. Fetch Vasily Agursky, will you, Gustav? Bring him here. I want to know what kind of an animal could do this, and he might be able to tell me.'

Litve gratefully made for the door, called back: 'The other's not much better, sir.'

'Other?' Khuv's mind still wasn't on business.

'Roborov.'

Khuv realized he'd been wandering. To make up for it he snapped, 'He was your colleague, wasn't he?'

'Was, sir, yes,' Litve answered. He went out.

Behind an overturned table, amidst a litter of bloodied paper money and cards, lay 'the other', Andrei Roborov. The two espers were standing looking down on him. Khuv shoved them aside, took a look for himself. Roborov's face was a mask of sheer horror. His dead eyes bulged; his jaws gaped in a frozen rictus of terror; his tongue projected, blue and glistening. Mainly cadaverous in life, he was totally grotesque in death. His thin head from the ears up looked like it had been trapped in a toothed vise and crushed. The skull had caved in, and blood and brain fluid seeped from the cracks and the deep punctures of... teeth marks?
