But she only had one window of opportunity. He only had one chance to convince her, and she had to act immediately. If she decided to call his bluff or to wait a couple of days, agonising about what to do, he was dead.

He was in her hands. Totally.

Clavain did what he could to extend the suit’s durability. He brought up certain rarely used neural routines that allowed him to slow his own metabolism, so that he would use as little air and power as possible. There was no real point in staying conscious; it gained him nothing except the opportunity to endlessly reflect on whether he was going to live or die.

Drifting alone in space, Clavain prepared to sink into unconsciousness. He thought of Felka, who he did not believe he would ever see again, and wondered about her message. He did not know if he wanted it to be true or not. He hoped also that she would find a way to come to terms with his defection, that she would not hate him for it and that she would not resent the fact that he had continued with it despite her plea.

He had originally defected to the side of the Conjoiners because he had believed it was the right thing to do under the circumstances. There had been almost no time to plan his defection or evaluate the correctness of it. The moment had arisen when he had to make his choice, there and then. He had known that there was no going back.

It was the same now. The moment had presented itself ... and he had seized it, mindful of the consequences, knowing that he might turn out to be wrong, that his fears might turn out to be groundless or the paranoid delusions of an old, old man, but knowing that it must be done.

That, he suspected, was the way it would always be for him.

He remembered a time when he lay under fallen rubble, in a pocket of air beneath a collapsed structure on Mars. It had been about four standard months after the Tharsis Bulge campaign. He remembered the broken-spined cat that he had kept alive, how he had shared his rations with the injured animal even when the thirst had felt like acid etching away his mouth and throat; even when the hunger had been far, far worse than the pain of his own injuries. He remembered that the cat had died shortly after the two of them had been pulled from the rubble, and wondered whether the kindest thing would have been for it to have died earlier, rather than have its own painful existence prolonged for a few more days. And yet he knew that if the same thing were to happen again he would keep the cat alive, no matter how pointless the gesture. It was not just that keeping the cat alive had given him something to focus on other than his own discomfort and fear. There had been something more. What, he couldn’t easily say. But he had a feeling that it was the same impulse that was driving him towards Yellowstone, the same impulse that had made him seek Antoinette Bax’s help.

Alone and fearful, far from any world, Nevil Clavain fell into unconsciousness.

SEVENTEEN

The two women brought Thorn to a room within
Nostalgia for Infinity
. The centrepiece of the room was an enormous spherical display apparatus, poised in the middle of the chamber like a single grotesque eyeball. Thorn had an unshakeable feeling of intense scrutiny, as if not just the eye but also the entire fabric of the ship was studying him with great owl-like interest and not a little malice. Then he began to take in the particulars of what confronted him. There was evidence of damage everywhere. Even the display apparatus itself appeared to have been subjected to recent and crude repairs.

‘What happened here?’ Thorn asked. ‘It looks as if there was a gunfight or something.’

‘We’ll never know for sure,’ Inquisitor Vuilleumier said. ‘Clearly the crew wasn’t as united as we thought during the Sylveste crisis. It looks from the internal evidence as if there was some sort of factional dispute aboard the ship.’

‘We always suspected this was the case,’ the other woman, Irina, added. ‘Evidently there was trouble brewing just below the surface. Seems that whatever happened around Cerberus/Hades was enough to spark off a mutiny. The crew must have killed each other, leaving the ship to take care of itself.’

‘Handy for us,’ Thorn said.

The women exchanged glances. ‘Perhaps we should move on to the item of interest,’ Vuilleumier said.

They played a movie for him. It was holographic, running in the big eye. Thorn assumed that it was a computer synthesis assembled from data that the ship had gathered from a multitude of sensor bands and viewpoints. What it presented was a God’s-eye view, the view of a being able to apprehend entire planets and their orbits.

‘I must ask you to accept something,’ Irina said. ‘It is difficult to accept, but it must be done.’

‘Tell me,’ Thorn said.

‘The entire human species is poised on the brink of sudden and catastrophic extinction.’

‘That’s quite a claim. I hope you can justify it.’

‘I can, and I will. The important thing to grasp is that the extinction, if it is to happen, will begin here, now, around Delta Pavonis. But this is merely the start of something that will become greater and bloodier.’

Thorn could not help but smile. ‘Then Sylveste was right, is that it?’

‘Sylveste knew nothing about the details, or the risks he was taking. But he was correct in one assumption: he believed that the Amarantin had been wiped out by external intervention, and that it had something to do with their sudden emergence as a spacefaring culture.’

‘And the same thing’s going to happen to us?’

Irina nodded. ‘The mechanism will be different this time, it seems. But the agents are the same.’

‘And they are?’

‘Machines,’ Irina told him. ‘Starfaring machines of immense age. For millions of years they’ve hidden between the stars, waiting for another culture to disturb the great galactic silence. All they exist to do is detect the emergence of intelligence and then suppress it. We call them the Inhibitors.’

‘And now they’re here?’

‘The evidence would suggest so.’

They showed him what had happened so far, how a squadron of Inhibitor machines had arrived in the system and set about the dismantling of three worlds. Irina shared with Thorn her suspicion that Sylveste’s activities had probably drawn them, and that there might even be further waves converging on the Resurgam system from further out, alerted by the expanding wavefront of whatever signal had activated the first machines.

He watched the three worlds die. One was a metallic planet; the other two were rocky moons. The machines swarmed and multiplied on the surfaces of the moons, covering them in a plaque of specialised industrial forms. From the equators, plumes of mined matter belched into space. The moons were being cored out like apples. The matter plumes were directed into the maws of three colossal processing engines orbiting the dying bodies. Streams of refined matter, segregated into distinct ores and isotopes and granularities, were then flung into interplanetary space, arcing out along lazy parabolas.

‘That was just the start,’ Vuilleumier said.

They showed him how the mass streams from the three dismantled moons converged on a single point in space. It was a point in the orbit of the system’s largest gas giant, and the giant planet would arrive at that point at exactly the same time as the three mass streams.

‘That was when our attention switched to the giant,’ Irena said.

The Inhibitor machines were fearfully difficult to detect. It was only with the greatest of effort that she had managed to discern the presence of another smaller swarm of machines around the giant. For a long time they had done nothing but wait, poised for the arrival of the matter streams, the hundred billion billion tonnes of raw material.

‘I don’t understand,’ Thorn said. ‘There are plenty of moons around the gas giant itself. Why did they go to the trouble of dismantling moons elsewhere if they were going to be needed here?’

‘Those aren’t the right sort of moon,’ Irina said. ‘Most of the moons around the giant aren’t much more than ice balls, small rocky cores surrounded by frozen or liquid-state volatiles. They needed to rip apart metallic worlds, and that meant looking further afield.’

‘And now what are they going to do?’

‘Make something else, it seems,’ Irina said. ‘Something bigger still. Something that needs one hundred billion billion tonnes of raw material.’

Thorn returned his attention to the eye. ‘When did this start? When did the matter streams reach Roc?’

‘Three weeks ago. The thing - whatever it is - is beginning to take shape.’ Irena tapped at a bracelet around her wrist, causing the eye to zoom in on the giant’s immediate neighbourhood.

Most of the planet remained in shadow. Above the one limb that was illuminated - an off-white crescent shot through with pale bars of ochre and fawn -
something
was suspended: a filamentary arc that must have been many thousands of kilometres from end to end. Irina zoomed in further, towards the middle of the arc.

‘It’s a solid object, so far as we can tell,’ Vuilleumier said. ‘An arc of a circle one hundred thousand kilometres in radius. It’s in an equatorial orbit around the planet, and the ends are growing.’

Irina zoomed in again, focusing on the precise midpoint of the growing arc. There was a swelling, little more than a lozenge-shaped smudge at the current resolution. She tapped more controls on the bracelet and the smudge bloomed into clarity, expanding to fill the entire display volume.

‘It was a moon in its own right,’ Irina said, ‘a ball of ice a few hundred kilometres from side to side. They circularised its orbit above the equator in a few days, without the moon breaking apart under the dynamic stresses. Then the machines built structures inside it, what we must assume to be additional processing equipment. One of the matter streams falls into the moon
here
, via this maw-shaped structure. We can’t speculate about what goes on inside, I’m afraid. All we know is that two tubular structures are emerging from either end of the moon, fore and aft of its orbital motion. On this scale they appear to be whiskers, but the tubes are actually fully fifteen kilometres in thickness. They currently extend seventy thousand kilometres either side of the moon, and are growing in length by a rate of around two hundred and eighty kilometres every hour.’

Irina nodded, noting Thorn’s evident incredulity. ‘Yes, that’s quite correct. What you see here has been achieved in the last ten standard days. We are dealing with an industrial capacity beyond anything in our experience, Thorn. Our machines can turn a small metal-rich asteroid into a starship in a few days, but even that would seem astonishingly slow by comparison with the Inhibitor processes.’

‘Ten days to form that arc.’ The hairs on the back of Thorn’s neck were standing up, to his embarrassment. ‘Do you think they’ll keep growing it until the ends meet?’

‘It seems likely. If the ends are to form a ring, they’ll meet in a little under ninety days.’

‘Three months! You’re right. We couldn’t do that. We never could; not even during the
Belle Époque
. Why, though? Why throw a ring around the gas giant?’

‘We don’t know. Yet. There’s more, though.’ Irina nodded at the eye. ‘Shall we continue?’

‘Show me,’ Thorn said. ‘I want to see it all.’

‘You won’t like it.’

She showed him the rest, explaining how the three individual mass streams had followed near-ballistic trajectories from their points of origin, like chains of pebbles tossed in precise formation. But near the gas giant they were tightly orchestrated, steered and braked by machines too small to see. They were forced to curve sharply, aimed towards whichever constructional focus was their destination. One stream rained down into the maw of the moon that was extruding out the whiskers. The other two streams plunged into similar mawlike structures on two other moons, both of which had been lowered into orbits just above the cloud layer, well within the radius at which they should have been shattered by tidal forces.

‘What are the other two moons doing?’ Thorn asked.

‘Something else, it seems,’ Irina said. ‘Here, take a look. See if you can make more sense of it than we’ve been able to.’

It was difficult to surmise exactly what was going on. There was a whisker of material emerging from each of the two lower moons, ejected aft, against the direction of orbital motion. The whiskers appeared to be about the same size as the arc that was being built by the higher moon, but they each followed a sinuous snakelike curve that took them from a tangent to the orbital motion into the atmosphere itself, like great telegraph cables being reeled into the sea by a ship. Immediately behind the impact point of each tube was an eyelike wake of roiling and disturbed atmosphere many thousands of kilometres long.

‘They don’t come out again, as far as we can see,’ Vuilleumier said.

‘How fast are they being laid?’

‘We can’t tell. There aren’t any reference points on the tubes themselves, so we can’t calculate how fast they’re emerging from the moons. There’s no way we can get a Doppler measurement, not without revealing our interest. But we know that the flux of matter falling into each of the three moons is about the same, and the tubes are all about the same width.’
