It was easily the most unsettling thing Vasko had ever seen in his life.

They circled closer.

Of all of them, only Clavain seemed unimpressed by the utter strangeness of what lay before them. ‘The smart maps were accurate,’ he said. ‘The size of this thing . . . by my reckoning, you could easily hide a moray-class corvette inside it.’

Vasko raised his voice. ‘You still think there might be a ship inside that thing, sir?’

‘Ask yourself a question, son. Do you really think Mother Nature had anything to do with this?’

‘But why would Skade surround her ship with all this strange ice?’ Vasko persisted. ‘I wouldn’t have thought it was much use as armour, and all it’s done so far is make her ship more visible on the maps.’

‘What makes you so sure she had any choice, son?’

‘I don’t follow, sir.’

Scorpio said, ‘He’s suggesting that all this might mean there’s something wrong with Skade’s ship. Isn’t that right?’

‘That’s my working hypothesis,’ Clavain said.

‘But what . . .’ Vasko abandoned his question before he got himself into even deeper water.

‘Whatever’s inside,’ Clavain said, ‘we still have to reach it. We don’t have tunnelling equipment or anything that can blast through thick ice. But if we’re careful, we won’t have to. We just have to locate a route through to the middle.’

‘What if Skade spots us, sir?’ Vasko asked.

‘I’m hoping she does. The last thing I want is to have to knock on her front door. Now take us closer. Nice and slowly does it.’

Bright Sun rose. In the early minutes of dawn, the iceberg took on an entirely different character. Against the soft violet of the sky the whole structure seemed magical, as delicate as some aristocrat’s confection. The briar spikes and icy spars were shot through with gold and azure, the colours refracted with the untainted dazzle of cut diamond. There were glorious halos, shards and jangles of chromatic purity, colours Vasko had never seen in his life. Instead of shadows, the interior shone turquoise and opal with a radiance that groped and fingered its way to the surface through twisting corridors and canyons of ice. And yet within that shining interior there was a shadowy kernel, a hint of something cocooned.

The two boats had come within fifty metres of the outer edge of the island’s fringe. The water had been calm for much of their journey, but here in the immediate vicinity of the iceberg it moved with the languor of some huge sedated animal, as if every ripple cost the sea great effort. Closer to the edge of the fringe, the sea was already beginning to freeze. It had the slick blue-grey texture of animal hide. Vasko touched his fingers just beneath the surface of the water by the boat and then pulled them back out immediately. Even here, this far from the fringe, the water was much colder than it had been when they had left the shuttle.

‘Look at this,’ Scorpio said. He had one of the smart maps rolled out before him. Khouri was studying it, too, obviously agreeing with something Scorpio was saying to her as he pointed out features with the blunt-trottered stub of one hand.

Clavain opened his own map. ‘What is it, Scorp?’

‘An update just came through from Blood. Take a look at the iceberg: it’s larger.’

Clavain made his map display the same coordinates. The iceberg leapt into view. Vasko peered over the old man’s shoulder, searching for the pair of boats. There was no sign of them. He assumed that the update had taken place before sunset the previous evening.

‘You’re right,’ Clavain said. ‘What would you say . . . thirty, forty per cent larger, by volume?’

‘Easily,’ Scorpio said. ‘And this
isn’t
real-time. If it’s growing this rapidly, it could be ten or twenty per cent larger again by now.’

Clavain folded his map: he had seen enough. ‘It certainly seems to be refrigerating the surrounding water. Before very long, where we’re sitting will be frozen as well. We’re lucky we arrived when we did. If we’d left it a few more days, we’d never have stood a chance. We’d be looking at a mountain.’

‘Sir,’ Vasko said, ‘I don’t understand how it can be getting larger. Surely it should be shrinking. Icebergs don’t last at these latitudes.’

‘I thought you said you didn’t know much about them,’ Clavain replied.

‘I said we don’t see many in the bay, sir.’

Clavain looked at him shrewdly. ‘It’s not an iceberg. It never was. It’s a shell of ice around Skade’s ship. And it’s growing because the ship is making it grow by cooling the sea around it. Remember what Khouri said? They have ways of making their hulls as cold as the cosmic microwave background.’

‘But you also said you didn’t think Skade had any control over this.’

‘I’m not sure she has.’

‘Sir . . .’

Clavain cut him off. ‘I think something may have gone wrong with the cryo-arithmetic engines that keep the hull cold. What, I don’t know. Perhaps Skade will tell us, when we find her.’

Until a day ago Vasko had never heard of cryo-arithmetic engines. But the phrase had cropped up in Khouri’s testimony - it was one of the technologies that Aura had helped Remontoire and his allies to perfect as they raced away from the ruins of the Delta Pavonis system.

In the hours that followed, Vasko had done his best to ask as many questions as possible, trying to fill in the most embarrassing voids in his knowledge. Not all of his questions had met with ready answers, even from Khouri. But Clavain had told him that the cryo-arithmetic engines were not completely new, that the basic technology had already been developed by the Conjoiners towards the end of their war against the Demarchists. At that time, a single cryo-arithmetic engine had been a clumsy thing the size of a mansion, too large to be carried on anything but a major spacecraft. All efforts to produce a miniaturised version had ended in disaster. Aura, however, had shown them how to make engines as small as apples.

But they were still dangerous.

The cryo-arithmetic principle was based on a controlled violation of thermodynamic law. It was an outgrowth from quantum computation, exploiting a class of algorithms discovered by a Conjoiner theorist named Qafzeh in the early years of the Demarchist war. Qafzeh’s algorithms - if implemented properly on a particular architecture of quantum computer - led to a net heat loss from the local universe. A cryo-arithmetic engine was in essence just a computer, running computational cycles. Unlike ordinary computers, however, it got colder the faster it ran. The trick - the really difficult part - was to prevent the computer from running even faster as it chilled, spiralling into a runaway process. The smaller the engine, the more susceptible it was to that kind of instability.

Perhaps that was what had happened to Skade’s ship. In space, the engines had worked to suck heat away from the corvette’s hull, making the ship vanish into the near-zero background of cosmic radiation. But the ship had sustained damage, perhaps severing the delicate web of control systems monitoring the cryo-arithmetic engines. By the time it hit Ararat’s ocean it had become a howling mouth of interstellar cold. The water had begun to freeze around it, the odd patterns and structures betraying the obscene violation of physical law taking place.

Could anyone still be alive inside it?

Vasko noticed something then. It was possible that he was the first. It was a keening sound at the very limit of his hearing, a sensation so close to ultrasound that he barely registered it as noise at all. It was more like a kind of data arriving by a sensory channel he had never known he possessed.

It was like singing. It was like a million fingers circling the wet rims of a million wine glasses.

He could barely hear it, and yet it threatened to split his skull open.

‘Sir,’ Vasko said, ‘I can hear something. The iceberg, sir, or whatever it is - it’s making a noise.’

‘It’s the sun,’ Clavain said, after a moment. ‘It must be warming the ice, stressing it in different ways, making it creak and shiver.’

‘Can you hear it, sir?’

Clavain looked at him with an odd expression on his face. ‘No, son, I can’t. These days, there are a lot of things I can’t hear. But I’m taking your word for it.’

‘Closer,’ Scorpio said.

Through dark, dank corridors of the great drowned ship, Antoinette Bax walked alone. She held a torch in one hand and the old silver helmet in the other, her fingers tucked through the neck ring. Lolloping ahead of her with the eagerness of a hunting dog, the wandering golden circle of torchlight defined the unsettling sculptural formations that lined the walls: here an archway that appeared to be made from spinal vertebrae, there a mass of curled and knotted intestinal tubes. The crawling shadows made the tubes writhe and contort like copulating snakes.

A steady damp breeze blew up from the lower decks, and from some unguessable distance Antoinette heard the clanging report of a hesitant, struggling mechanism - a bilge pump, maybe, or perhaps the ship itself remaking a part of its own fabric. Sounds propagated unpredictably through the ship, and the noise could just as easily have originated mere corridors away as from some location kilometres up or down the spire.

Antoinette hitched high the collar of her coat. She would have preferred company - any company - but she knew that this was the way it had to be. On each of the very few occasions in the past when she had elicited anything from the Captain that might be construed as a meaningful response, it had always been when she was alone. She took this as evidence that the Captain was prepared to reveal himself to her, and that there was an element of trust - however small - in their relationship. True or not, Antoinette had always believed that she stood a better chance of communicating with the Captain than her peers did. It was all about history. She had owned a ship herself once, and although that ship had been much smaller than the
Nostalgia for Infinity
, in some sense it, too, had been haunted.

‘Talk to me, John,’ she had said on previous occasions. ‘Talk to me as someone you can trust, as someone who appreciates a little of what you are.’

There had never been an unequivocal answer, but if she looked at all the instances when she had drawn some response, however devoid of content, it appeared to her that the Captain was more likely to do
something
in her presence than not. Taken together, none of these apparitions amounted to any kind of coherent message. But what if the recent spate of manifestations pointed to him emerging from some dormant state?

‘Captain,’ she said now, holding aloft the helmet, ‘you left a calling card, didn’t you? I’ve come to give it back. Now you have to keep your side of the bargain.’

There was no response.

‘I’ll be honest with you,’ she said. ‘I really don’t like it down here. Matter of fact, it scares the hell out of me. I like my ships small and cosy, with décor I chose myself.’ She cast the torch beam around, picking out an overhanging globular mass filling half the corridor. She stooped under the shock-frozen black bubbles, brushing her fingers against their surprising warmth and softness. ‘No, this isn’t me at all. But I guess this is your empire, not mine. All I’m saying is that I hope you realise what it takes to bring me down here. And I hope you’re going to make it worthwhile for me.’

Nothing happened. But she had never expected success at first bite.

‘John,’ she said, deciding to risk familiarity, ‘we think something may be happening in the wider system. My guess is you may have some suspicions about this as well. I’ll tell you what we think, anyway - then you can decide for yourself.’

The character of the breeze changed. It was warmer now, with an irregularity about it that made her think of ragged breathing.

Antoinette said, ‘Khouri came back. She dropped out of the sky a couple of days back. You remember Khouri, don’t you? She spent a lot of time aboard, so I’d be surprised if you didn’t. Well, Khouri says there’s a battle going on around Ararat, something that makes the Demarchist-Conjoiner war look like a snowball fight. If she isn’t lying, we’ve got two squabbling human factions up there, plus a really frightening number of wolf machines. You remember the wolves, don’t you, Captain? You saw Ilia throw the cache weapons at them, and you saw what good it did.’

There it was again. The breeze had become a faint suction.

In Antoinette’s estimation that already made it a class-one apparition. ‘You’re here with me, aren’t you?’

Another shift in the wind. The breeze returned, sharpened to a howl. The howl ripped her hair loose, whipping it in her eyes.

She heard a word whispered in the wind:
Ilia
.

‘Yes, Captain. Ilia. You remember her well, don’t you? You remember the Triumvir. I do, too. I didn’t know her for long, but it was long enough to see that she isn’t the kind of woman you’d forget in a hurry.’

The wind had died down. All that remained was a nagging suction.

A small, sane voice warned Antoinette to stop now. She had achieved a clear result: a class one by anyone’s definition, and almost certainly (if she had not imagined the voice) a class two. That was enough for one day, wasn’t it? The Captain was nothing if not temperamental. According to the records she had left behind, Ilia Volyova had pushed him into a catatonic sulk many times by trying to coax just one more response from him. Often it had taken the Captain weeks to emerge from one of those withdrawals.
