‘No; I wouldn’t expect you to. It was nothing he told you, either . . . but I think he did find a way to tell you the truth.’ The memory process she had suppressed a moment earlier had indeed dredged something. She thought back to the time of Khouri’s recruitment; to the examination she had given the woman after she had been brought aboard. ‘I can’t be sure yet, of course . . .’

  Khouri looked at her. ‘You found something on me, didn’t you? Something Manoukhian planted?’

  ‘Yes. It seemed quite innocent, at first. Fortunately, I have an odd character defect, common amongst those of us who indulge in the sciences . . . I never, ever throw anything away.’ It was true; disposing of the thing she had found would have demanded a greater expenditure of effort than simply leaving it in her lab. It had seemed pointless at the time - the thing was just a shard, after all - but now she could run a compositional analysis on the metal splinter she had pulled from Khouri. ‘If I’m right, and this was Manoukhian’s doing, it may tell us something about the Mademoiselle. Perhaps even her identity. But you still need to tell me what exactly she wanted you to do for her. We already know it involves Sylveste in some way or another.’

  Khouri nodded. ‘It does. And I’m afraid this is the part you’re really not going to like.’

  ‘We’ve completed a more detailed inspection of the surface of Cerberus from our present orbit,’ Alicia’s projection said. ‘And there’s still no evidence of the cometary impact point. Plenty of cratering, yes - but none of it recent. Which just doesn’t make any sense.’ She elaborated the one plausible theory they had, which was that the comet had been destroyed just before impact. Even that explanation implied the use of some form of defensive technology, but at least it avoided the paradox of the unchanged surface features. ‘But we saw no sign of anything like that, and there’s certainly no evidence of any technological structures on the surface. We’ve decided to launch a squadron of probes down to the surface. They’ll be able to hunt for anything we might have missed - machines buried in caves, or sunk in canyons below our viewing angle - and they might provoke some kind of response, if there are automated systems down there.’

  Yes, Sylveste thought acidly. They had indeed provoked some kind of response. But it was almost certainly not the kind Alicia had anticipated.

  Volyova located the next segment in Alicia’s narrative. The probes had been deployed; tiny automated spacecraft as fragile and nimble as dragonflies. They had fallen towards the surface of Cerberus - there was no atmosphere to retard them - only arresting their descent at the last moment, with quick spurts of fusion flame. For a while, seen from the vantage point of the Lorean, they had been sparks of brightness against the unremitting grey of Cerberus. But as the sparks had become tiny, they were a reminder that even this tiny, dead world was orders of magnitude larger than most human creations.

  ‘Log entry,’ said Alicia, after a gap in the narrative. ‘The probes are reporting something unusual - it’s just coming in now.’ She looked to one side, consulting a display beyond the projection volume. ‘Seismic activity on the surface. We were expecting to see it already, but until now the crust hasn’t moved at all, even though the planet’s orbit isn’t quite circularised and there should be tidal stresses. It’s almost as if the probes have triggered it, but that’s quite ridiculous.’

  ‘No more so than a planet that erases all evidence of a cometary impact on its surface,’ Pascale said. Then she looked at Sylveste. ‘I didn’t mean that as a criticism of Alicia, by the way.’

  ‘Perhaps you didn’t,’ he said. ‘But it would have been valid.’ Then he turned to Volyova. ‘Did you recover anything other than Alicia’s log entries? There must have been telemetered data from her probes . . .’

  ‘We have it,’ Volyova said cautiously. ‘I haven’t cleaned it up. It’s a little on the raw side.’

  ‘Patch me in.’

  Volyova breathed a string of commands into the bracelet she always wore and the bridge burned away, a barrage of synaesthesia jumbling Sylveste’s senses. He was being immersed in the data from one of Alicia’s probes - the surveyor’s sensorium fully as raw as Volyova had warned. But Sylveste had known more or less what to expect; the transition was merely jarring rather than - as could easily have been the case - agonising.

  He floated above a landscape. Altitude was difficult to judge, since the fractal surface features - craters, clefts and rivers of frozen grey lava - would have looked very similar at any distance. But the surveyor told him he was only half a kilometre above Cerberus. He looked down at the plain, hunting for some sign of the seismic activity Alicia had mentioned. Cerberus looked eternally old and unchanging, as if nothing had happened to it for billions of years. The only hint of motion came from the fusion jets, casting radial shadows away from his position as the machine loitered.

  What had the drones seen? Certainly nothing in the visual band. Feeling his way into the sensorium - it was like slipping on an unfamiliar glove - Sylveste found the neural commands which accessed different data channels. He turned to thermal sensors, but the plain’s temperature showed no signs of variation. Across the complete EM spectrum there was nothing anomalous. Neutrino and exotic particle fluxes remained steadfastly within expectation. Yet when he switched to the gravitational imagers, he knew that something was very wrong with Cerberus. His visual field was overlaid with coloured, translucent contours of gravitational force. The contours were moving.

  Things - huge enough to register via the mass sensors - were travelling underground, converging in a pincer movement directly below the point where he was hovering. For a moment, he allowed himself to believe that these moving forms were only vast, buried flows of lava - but that comforting delusion lasted no more than a second.

  This was nothing natural.

  Lines appeared on the plain, forming a starlike mandala centred on the same focus. Dimly, on the limits of his perception, he was aware that similar starlike patterns were opening below the other probes. The cracks widened, opening into monstrous black fissures. Through the fissures, Sylveste had a glimpse into what seemed to be kilometres of luminous depth. Coiled mechanical shapes writhed, sliding blue-grey tendrils wider than canyons. The motion was busy; orchestrated, purposeful, machinelike. He felt a special kind of revulsion. It was the feeling of biting an apple and exposing a colony of wrigglingly industrious maggots. He knew now. Cerberus was not a planet.

  It was a mechanism.

  Then the coiled things erupted through the star-shaped hole in the plain, rushing dreamily towards him, as if reaching to snatch him out of the sky. There was a horrible moment of whiteness - a whiteness in every sense he had - before Volyova’s sensorium-feed ended with screaming suddenness, Sylveste almost shrieking with existential shock as his sense of self crashed back into his body in the bridge.

  He had time enough, after he had gathered his faculties, to observe Alicia mouthing something soundlessly, her face carved in what might have been fear, and what might equally have been the dismay at learning - in the instant prior to her death - that she had been wrong all along.

  Then her image dissolved into static.

  ‘Now at least we know he’s mad,’ Khouri said, hours later. ‘If that didn’t persuade him against going any closer to Cerberus, I don’t think anything will.’

  ‘It may well have had the opposite effect,’ Volyova said, voice low despite the relative security furnished by the spider-room. ‘Now Sylveste knows there is something worth investigating, rather than merely suspecting so.’

  ‘Alien machinery?’

  ‘Evidently. And perhaps we can even guess at the purpose, too. Cerberus clearly isn’t a real world. At the very least, it’s a real world surrounded by a shell of machines, with an artificial crust. That explains why the cometary impact-point was never found - the crust, presumably, repaired itself before Alicia’s crew could get close enough.’

  ‘Some kind of camouflage?’

  ‘So it would seem.’

  ‘So why draw at
tention by attacking those probes?’

  Volyova had evidently given the matter some prior thought. ‘The illusion of verisimilitude obviously can’t be foolproof at distances less than a kilometre or so. My guess is the probes were about to learn the truth just before they were destroyed, so the world lost nothing and gained some additional raw material in the bargain.’

  ‘Why, though? Why surround a planet with a false crust?’

  ‘I have no idea, and neither, I suspect, does Sylveste. That’s why he’s now even more likely to insist on going closer.’ She lowered her voice. ‘He’s already asked me to devise a strategy, in fact.’

  ‘A strategy for what?’

  ‘For getting him inside Cerberus.’ She paused. ‘He knows about the cache-weapons, of course. He presumes they’ll be sufficient to achieve his aims, by weakening the crustal machinery in one area of the planet. More than that will be needed, of course . . .’ Her tone of voice shifted. ‘Do you think this Mademoiselle of yours always knew this would be his objective?’

  ‘She was pretty damn clear he shouldn’t be allowed aboard the ship.’

  ‘The Mademoiselle told you that before you joined us?’

  ‘No; afterwards.’ She told Volyova about the implant in her head; how the Mademoiselle had downloaded an aspect of herself into Khouri’s skull for the purposes of the mission. ‘She was a pain,’ she said. ‘But she made me immune to your loyalty therapies, which I suppose was something to be grateful for.’

  ‘The therapies worked as intended,’ Volyova said.

  ‘No, I just pretended. The Mademoiselle told me what to say and when, and I guess she didn’t do too bad a job, or else we wouldn’t be having this discussion.’

  ‘She can’t rule out the possibility that the therapies worked partially, can she?’

  Khouri shrugged again. ‘Does it matter? What kind of loyalty would make any sense now? You’ve as good as told me you’re waiting for Sajaki to make the wrong move. The only thing holding this crew together is Sylveste’s threat to kill us all if we don’t do what he wants. Sajaki’s a megalomaniac - maybe he should have double-checked the therapies he was running on you.’

  ‘You resisted Sudjic when she tried to kill me.’

  ‘Yeah, I did. But if she’d told me she was going after Sajaki - or even that prick Hegazi - I don’t know what I would have said.’

  Volyova spent a moment in consultation with herself.

  ‘All right,’ she said finally. ‘I suppose the loyalty issue is moot. What else did the implant do for you?’

  ‘When you hooked me into the weapons,’ Khouri said, ‘she used the interface to inject herself - or a copy of herself - into the gunnery. To begin with I think she just wanted to assume control of as much of the ship as possible, and the gunnery was her only point of entry.’

  ‘The architecture wouldn’t have allowed her to reach beyond it.’

  ‘It didn’t. To the best of my knowledge, she never gained control of any part of the ship other than the weapons.’

  ‘You mean the cache?’

  ‘She was controlling the rogue weapon, Ilia. I couldn’t tell you at the time, but I knew what was happening. She wanted to use the weapon to kill Sylveste at long-range, before we’d ever arrived at Resurgam.’

  ‘I suppose,’ Volyova said, heavy with resignation, ‘that it makes a kind of twisted sense. But to use that weapon just to kill a man . . . I told you, you’re going to have to tell me why she wanted him dead so badly.’

  ‘You won’t like it. Especially not now, with what Sylveste wants to do.’

  ‘Just tell me.’

  ‘I will, I will,’ Khouri said. ‘But there’s one other thing - one other complicating factor. It’s called Sun Stealer, and I think you may already be acquainted with it.’

  Volyova looked as if some recently healed internal injury had just relapsed; as if some painful seam had opened in her like ripping cloth. ‘Ah,’ she said eventually. ‘That name again.’

  TWENTY-ONE

  Approaching Cerberus/Hades, 2566

  Sylveste had always known this point would come. But until now he had managed to keep it quarantined from his thoughts, acknowledging its existence without focusing his attention on what it actually entailed, the way a mathematician might ignore an invalidated part of a proof until the rest was rigorously tested and found to be free not just of glaring contradictions but of the least hint of error.

  Sajaki had insisted that they journey alone to the Captain’s level, forbidding Pascale or any of the crew to accompany them. Sylveste did not argue the point, although he would have preferred his wife to be with him. It was the first time that Sylveste had been alone with Sajaki since arriving on the Infinity, and as they took the elevator downship, Sylveste ransacked his mind for something to talk about; anything except the atrocity that lay ahead of them.

  ‘Ilia says her machines aboard the Lorean will need another three or four days,’ Sajaki said. ‘You’re quite certain you wish her work to continue?’

  ‘I have no second thoughts,’ Sylveste said.

  ‘Then I have no choice but to comply with your wishes. I’ve weighed the evidence and decided to believe your threat.’

  ‘You imagine I hadn’t worked that out for myself already? I know you too well, Sajaki. If you didn’t believe me, you’d have forced me into helping the Captain while we were still around Resurgam, and then quietly disposed of me.’

  ‘Not true, not true.’ Sajaki’s voice had an amused quality to it. ‘You underestimate my sheer curiosity. I think I’d have indulged you this far just to see how much of your story was true.’

  Sylveste was incapable of believing that for a moment, but equally, he saw no point in debating it. ‘Just how much of it don’t you believe, now that you’ve seen Alicia’s message?’

  ‘But that could so easily have been faked. The damage to her ship could have been inflicted by her own crew. I shan’t believe things entirely until something jumps out of Cerberus and starts attacking us.’

  ‘I rather suspect you’ll get your wish,’ Sylveste said. ‘In four or five days. Unless Cerberus really is dead.’

  They spoke no more until they had reached their destination.

  It was not, of course, the first time he had seen the Captain - not even during this visit. But the totality of what had become of the man was still shocking; each time it was as if Sylveste had never properly set eyes on the scene before. True enough: this was his first visit to the Captain’s level since Calvin had renewed his eyes using the ship’s superior medical capabilities, but there was more to it than that. It was also the case that the Captain had changed since last time; perceptibly now - as if his rate of spread was accelerating, racing towards some unguessable future state even as the ship raced towards Cerberus. Perhaps, Sylveste thought, he had arrived in the nick of time - assuming that any intervention at all could help the Captain now.

  It was tempting to think that this quickening was significant; perhaps even symbolic. The man, after all, had been sick - if one could properly call this state sickness - for many decades, and yet he had chosen this period in which to enter a new phase of his malady. But that was an erroneous view. One had to consider the Captain’s time-frame: relativistic flight had compressed those decades to a mere handful of years. His latest blooming was less unlikely than it seemed; there was nothing ominous about it.

  ‘How does this work?’ Sajaki asked. ‘Do we follow the same procedures as last time?’

  ‘Ask Calvin - he’ll be running things.’

  Sajaki nodded slowly, as if the point had only just occurred to him. ‘You should have a say in things, Dan. It’s you he’ll be working through.’

  ‘Which is exactly why you don’t need to consider my feelings - I won’t even be present.’

  ‘I don’t believe that for one moment. You’ll be there, Dan - fully aware, too, from what I remember last time. Maybe not in control, but you’ll be participating. And you won’t like it - we kno
w that much from last time.’

  ‘You’re an expert all of a sudden.’

  ‘If you didn’t hate this, why would you have kept away from us?’

  ‘I didn’t. I wasn’t in any position to run.’

  ‘I’m not just talking about the time when you were in prison. I’m talking about you coming here in the first place; to this system. What were you doing if you weren’t running from us?’

  ‘Maybe I had reasons for coming here.’

  For a moment Sylveste wondered if Sajaki was going to push the matter further, but the moment passed and the Triumvir seemed to mentally discard that line of enquiry. Perhaps the topic bored him. It struck Sylveste that Sajaki was a man who existed in the present and thought largely about the future, and for whom the past held few enticements. He was not interested in sifting through possible motivations or might-have-beens, perhaps because, on some level, Sajaki was not really capable of grasping these issues.

  Sylveste had heard that Sajaki had visited the Pattern Jugglers, as he himself had done prior to the Shrouder mission. There was only one reason for visiting the Jugglers, which was to submit oneself to their neural transformations, opening the mind to new modes of consciousness unavailable through human science. It was said - rumoured, perhaps - that no Juggler transform was without its deficits; that there was no resculpting of the human mind which did not result in some pre-existing faculty being lost. There were, after all, only a finite number of neurones in the human brain, and a corresponding finite limit to the number of possible interneuronal connections. The Jugglers could rewire that network, but not without destroying prior connectional pathways. Perhaps Sylveste himself had lost something, but if that were the case, he could not locate the absence. In Sajaki’s case, it might be more obvious. The man was missing some instinctive grasp of human nature, almost an autism. There was an aridity in his conversations, but it was only clear if one paid proper attention. In Calvin’s laboratories back on Yellowstone, Sylveste had once spoken to an early, historically preserved computer system which had been created several centuries before the Transenlightenment, during the first flourishing of artificial intelligence research. The system purported to mimic natural human language, and initially it did, answering inputted questions with apparent cognisance. But the illusion lasted for no more than a few exchanges; eventually one realised that the machine was steering the conversation away from itself, deflecting questions with a sphinxlike impassiveness. It was far less extreme with Sajaki, but the same sense of evasion was present. It was not even particularly artful. Sajaki made no effort to disguise his indifference to these matters; there was no sociopathic gloss of superficial humanity. And why should Sajaki even bother to deny his nature? He had nothing to lose, and in his own way, he was no more or less alien than any of the other crew.
