fastest ship here, and probably the one with the smallest sensor footprint. Light armour, though, and the weapons are more for show than anything else. You want something better armoured, we’ll take it — just don’t complain if it’s slow and easily tracked.’ ‘I’ll let you be the judge.’ ‘This is very foolish, Thorn. There’s still time to chicken out.’ ‘It isn’t a question of foolishness or otherwise, Inquisitor.’ He could not snap out of the habit of calling her that. ‘I simply won’t co-operate until I know that this threat is real. Until I can verify that for myself — with my own eyes, and not through a screen –1 won’t be able to trust you.’ ‘Why would we lie to you?’ ‘I don’t know, but you are, I think.’ He had studied her carefully, their eyes meeting, he holding her gaze for a moment longer than was comfortable. ‘About something. I’m not sure what, but neither of you are being totally honest with me. Yet some of the time you are, and that’s the part I don’t fully understand.’ ‘All we want to do is save the people of Resurgam.’ ‘I know. I believe that part, I really do.’ They had taken the snake-headed ship, leaving Irina back aboard the larger vessel. The departure had been rapid, and though he had done his best, Thorn had not been able to sneak a look backwards. He had still not seen Nostalgia for Infinity from the outside, not even on the approach from Resurgam. Why, he wondered, would the two of them go to such lengths to hide the outside of their ship? Perhaps he was just imagining it, and he would get that view on the way back. ‘You can take the ship yourself,’ Irina had told him. ‘It doesn’t need flying. We can program a trajectory into it and let the autonomics handle any contingency. Just tell us how close you want to get to the Inhibitors.’ ‘It doesn’t have to be close. A few tens of thousands of kilometres should be good enough. I’ll be able to see that arc, if it’s bright enough, and probably the tubes that are being dropped into the atmosphere. But I’m not going out there on my own. If you want me badly enough, one of you can come with me. That way I’ll know it really isn’t a trap, won’t I?’ ‘I’ll go with him,’ Vuilleumier had offered. Irina had shrugged. ‘It’s been nice knowing you.’ The trip out had been uneventful. As on the journey from Resurgam, they had spent the boring part of it asleep — not in reefersleep, but in a dreamless drug-induced coma. Vuilleumier did not wake them until they were within half a light-second of the giant. Thorn awoke with a vague sense of irritation, a bad taste in his mouth and various aches and pains where there had been none before. ‘Well, the good news is that we’re still alive, Thorn. The Inhibitors either don’t know we’re here, or they just don’t care.’ ‘Why wouldn’t they care?’ ‘They must know from experience that we can’t offer them any real trouble. In a little while we’ll all be dead, so why worry about one or two of us now?’ He frowned. ‘Experience?’ ‘It’s in their collective memory, Thorn. We’re not the first species they’ve done this to. The success rate must be pretty high, or else they’d revise the strategy.’ They were in free-fall. Thorn unhitched from his seat, tugging aside the acceleration webbing, and kicked over to one of the slitlike windows. He felt a little better now. He could see the gas giant very clearly, and it did not look like a well planet. The first things that he noticed were the three great matter streams curving in from elsewhere in the system. They twinkled palely in the light from Delta Pavonis, thin ribbons of translucent grey like great ghostly brushstrokes daubed across the sky, flat to the ecliptic and sweeping away to infinity. The flow of matter along the streams was just tangible, as one boulder or another caught the sun for an instant; it was a fine-grained creep that reminded Thorn of the sluggish currents in a river on the point of freezing. The matter was travelling at hundreds of kilometres per second, but the sheer immensity of the scene rendered even that speed glacial. The streams themselves were many, many kilometres wide. They were, he supposed, like planetary rings that had been unwound. His gaze followed the streams to their conclusions. Near the gas giant, the smooth mathematical curves — arcs describing orbital trajectories — were curtailed by abrupt hairpins or doglegs as the streams were routed to particular moons. It was as if the artist painting the elegant swathes had been jolted at the last instant. The orientation of the moons with respect to the arriving streams was changing by the hour, of course, so the stream geometries were themselves subject to constant revision. Now and then a stream would have to be dammed back, the flow stopped while another intersected it. Or perhaps it was done with astonishingly tight timing, so that the streams passed through each other without any of the constituent masses actually colliding. ‘We don’t know how they steer them like that,’ Vuilleumier told him, her voice low and confidential. ‘There’s a lot of momentum in those streams, mass fluxes of billions of tonnes a second. Yet they change direction easily. Maybe they’ve got tiny little black holes positioned up there, so they can slingshot the streams around them. That’s what Irina thinks, anyway. Scares the hell out of me, I can tell you. Although she thinks they might also be able to turn off inertia when they need to, so they can make the streams swerve like that.’ ‘That doesn’t sound much more encouraging.’ ‘No, it doesn’t. But even if they can do that to inertia, or make black holes to order, they obviously can’t do it on a huge scale or we’d be dead already. They have their limitations. We have to believe that.’ The moons, a few dozen kilometres wide, were visible as tight knots of light, barbs on the ends of the infailing streams. The matter plunged into each moon through a mouthlike aperture, perpendicular to the plane of orbital motion. By rights, the unbalanced mass flux should have been forcing each moon into a new orbit. Nothing like that was happening, which suggested that, again, the normal laws of momentum conservation were being suppressed, or ignored, or put on hold until some later reckoning. The outermost moon was laying the arc that would eventually enclose the gas giant. When Thorn had seen it from Nostalgia for Infinity it had been possible to believe that it was never destined for closure. No such assurance was possible now. The ends had continued moving outwards from the moon, the tube being extruded at a rate of a thousand kilometres every four hours. It was emerging as quickly as an express train, an avalanche of super-organised matter. It was not magic, just industry. Thorn reminded himself of that, difficult as it was to believe it. Within the moon, mechanisms hidden beneath its icy crust were processing the incoming matter stream at demonic speed, forging the unguessable components that formed the thirteen-kilometre-wide tube. The two women had not speculated in his presence about whether the tube was solid or hollow or crammed with twinkling alien clockwork. But it was not magic. Physical laws as Thorn understood them might be melting like toffee in the vicinity of the Inhibitor engines, but that was only because they were not the ultimate laws they appeared to be, rather mere statutes or regulations to be adhered to most of the time but broken under duress. Yet even the Inhibitors were constrained to some degree. They could work wonders, but not the impossible. They needed matter, for instance. They could work it with astonishing speed, but
