‘A few days won’t make much difference. No, that definitely wasn’t it. There was something else. You two were hiding something, or hoping I wouldn’t notice something. I just can’t work out exactly what it was.’
‘You have to trust us, Thorn.’
‘You make it difficult, Ana.’
‘What else could we do? We showed you the ship, didn’t we? You saw that it was real. It has enough capacity to evacuate the planet. We even showed you the shuttle hangar.’
‘Yes,’ he said. ‘But it’s everything that you didn’t show me that makes me wonder.’
The rumbling had increased. The ship felt as if it was tobogganning down an ice-slope, hitting the occasional buried rock. The hull creaked and reshaped itself again and again, struggling to smooth out the transition. Thorn found himself excited and terrified at the same time. He had entered a planet’s atmosphere only once before in his life, when his parents had brought him as a child to Resurgam. He had been frozen and unconscious at the time, and had no more recollection of it than he did of his birth in Chasm City.
‘We didn’t show you everything because we don’t know that the whole of the ship is safe,’ Vuilleumier said. ‘We don’t know what sorts of traps Volyova’s crew left behind.’
‘You didn’t even let me see it from outside, Ana.’
‘It wasn’t convenient. Our approach—’
‘Had nothing to do with it. There’s something about that ship that you can’t let me see, isn’t there?’
‘Why are you asking me this now, Thorn?’
He smiled. ‘I thought the gravity of the situation would focus your attention.’
She said nothing.
Presently, the ride became smoother. The airframe creaked and reshaped one last time. Vuilleumier waited another few minutes and then raised the armoured eyelids. Thorn blinked against the sudden intrusion of daylight. They were inside the atmosphere of Roc.
‘How do you feel?’ she asked. ‘Your weight has doubled since we were aboard the ship.’
‘I’ll manage.’ He was fine provided he did not have to move around. ‘How deep did you take us?’
‘Not far. Pressure’s about half an atmosphere. Wait . . .’ At that moment she frowned at something on one of her displays, tapping controls below it so that the image shifted through pastel-coloured bands. Thorn saw a simplified silhouette of the ship they were in, surrounded by pulsing, concentric circles. He suspected it was some form of radar, and saw a small smudge of light wink in and out of existence on the limit of the display. She tapped another control and the concentric circles tightened, bringing the smudge closer. Now it was there, now it was gone, now it was there again.
‘What’s that?’ Thorn asked.
‘I don’t know. Passive radar says there’s something following us, about thirty thousand klicks astern. I didn’t see anything on our approach. It’s small and it doesn’t seem to be getting any closer, but I don’t like it.’
‘Could it be a mistake, an error that the ship’s making?’
‘I’m not sure. I suppose the radar might be confused, picking up a false return from our wake vortex. I could switch to a focused active sweep, but I really don’t want to provoke anything I don’t have to. I suggest we get away from here while we still can. I’m a firm believer in listening to warnings.’
Thorn tapped the console. ‘And how do I know that you didn’t arrange for that bogey to appear?’
She laughed the sudden, nervous laugh of a person caught completely unawares. ‘I didn’t, believe me.’
Thorn nodded, sensing that she was telling the truth - or at least lying very well indeed. ‘Perhaps not. But I still want you to steer us towards the impact site, Ana. I’m not leaving until I see what’s happening here.’
‘You’re serious, aren’t you?’ She waited for him to answer, but Thorn said nothing, looking at her unflinchingly. ‘All right,’ Vuilleumier said finally. ‘We’ll get close enough that you can see things for yourself. But no closer than that. And if that other thing shows any signs of coming nearer, we’re out of here. Got that?’
‘Of course,’ he said mildly. ‘What do you think I am, suicidal?’
Vuilleumier plotted an approach. The impact point was moving at thirty kilometres per second relative to Roc’s atmosphere, its pace determined by the orbital motion of the moon that was extruding the tube. They came in from the rear, shadowing the impact point, increasing their speed. The hull contorted itself again, dealing with the increasing Mach numbers; all the while the smudge on the passive radar lingered behind them, shifting in and out of clarity, sometimes vanishing entirely, but never moving relative to their own position.
‘I feel lighter,’ Thorn said.
‘You will. We’re nearly orbiting again. If we went much faster I’d have to apply thrust to hold us down.’
In the wake of the impact the atmosphere was curdled and turbulent, rare chemistries staining cloud layers with sooty reds and vermilions. Lightning flickered from horizon to horizon, arcing across the sky in stuttering silver bridges as transient charge differentials were smoothed out. Furious eddies whirled like dervishes. The ship’s manifold passive sensors probed ahead, groping for a trajectory between the worst of the storms.
‘I don’t see the tube yet,’ Thorn said.
‘You won’t, not until we’re much closer. It’s only thirteen kilometres across, and I doubt that we could see more than a hundred kilometres in any direction even without the storm.’
‘Do you have any idea what they’re doing?’
‘I wish I did.’
‘Planetary engineering, obviously. They ripped apart three worlds for this, Ana. They must mean business.’
They continued their approach, the ride becoming rougher. Vuilleumier dipped them up and down by tens of kilometres, until she decided not to risk any further use of the Doppler radar. Thereafter she held a steady altitude, the ship bucking and shaking as it slammed through vortices and shear walls. Alarms went off every other minute, and now and again Vuilleumier would swear and tap a rapid sequence of commands into the control panel. The air around them was growing pitch-dark. Mighty black clouds billowed and surged, contorted into looming visceral shapes. Thunderheads larger than cities whipped past in an instant. Ahead, the air pulsed and blazed with constant electrical discharges: blinding forked white branches and twisting sheets of baby blue. They were flying into a small pocket of hell.
‘Doesn’t seem like quite such a good idea now, does it?’ Vuilleumier commented.
‘Never mind,’ Thorn said. ‘Just keep us on this heading. The bogey hasn’t come any closer, has it? Maybe it was just a reflection from our wake.’ As he spoke, something else snared Vuilleumier’s attention on the console. An alarm started whooping, a chorus of multilingual voices shouting incomprehensible warning messages.
‘Mass sensor says there’s something up ahead, seventy-odd kilometres distant,’ she said. ‘Elongated, I think - the field geometry’s cylindrical, with an inverse “r” attenuation. That’s got to be our baby.’
‘How long until we see it?’
‘We’ll be there in five minutes. I’m slowing our rate of approach. Hold on.’
Thorn pitched forwards in his seat restraints as Vuilleumier killed the speed. He counted out five minutes, then another five. The smudge on the passive radar display held its relative position, slowing as they did. Strangely, the ride became even smoother. The clouds began to thin out; the savage electrical activity became little more than a constant distant strobing on either side of them. There was a horrible sense of unreality about it.
‘Air pressure’s dropping,’ Vuilleumier said. ‘I think there must be a low-pressure wake behind the tube. It’s slicing through the atmosphere supersonically, so that the air can’t immediately rush around and close the gap. We’re inside the Mach cone of the tube, as if we were flying right behind a supersonic aircraft.’
‘You sound like you know what you’re talking about - for an Inquisitor, anyway.’
‘I’ve had to learn, Thorn. And I’ve had a good teacher.’
‘Irina?’ he asked, amusedly.
‘We make a pretty good team. But it wasn’t always the case.’ Then she looked ahead and pointed. ‘Look. I can see something, I think. Let’s try some magnification and then get the hell back out into space.’ On the main console display appeared an image of the tube. It plunged down into the atmosphere from above them, angled to the horizontal by forty or forty-five degrees. Against the slate background of the atmosphere it was a line of shining silver, like the funnel of a twister. They could see perhaps eighty kilometres of its length; above and below it vanished into haze or roiling clouds. There was no sense of motion along the tube, even though it was flowing into the depths at a rate of a kilometre every four seconds. It appeared to be suspended, even unmoving.
‘No sign of anything else,’ Thorn said. ‘I don’t know quite what I was expecting, but I thought there’d be something else. Deeper, maybe. Can you take us forwards?’
‘We’ll have to pass through the transonic boundary. It’ll be a lot rougher than anything we’ve gone through so far.’
‘Can we handle it?’
‘We can try.’ Vuilleumier grimaced and worked the controls again. The air in front of the tube was perfectly steady and calm, utterly unaware of the shock wave that was racing towards it. Even the last passage of the tube on the previous swing-round of the moon had been thousands of kilometres to one side of its present trajectory. Air immediately in front of the tube was compressed into a fluid layer only centimetres thick, forming a v-shaped shock wave at each point along the tube’s length. There was no way to get ahead of the tube without passing through that wing of savagely compressed and heated air; not unless Vuilleumier accepted a detour of many thousands of kilometres.
They passed to one side of the tube. It shone cherry-red along the leading edge, evidence of the frictional energies dissipated in its passage. But there was no sign of any harm being done to the alien machinery.
‘It’s being fed downwards,’ Thorn said. ‘But there isn’t anything down there. Just a lot of gas.’
‘Not all the way down,’ said Vuilleumier. ‘The gas turns into liquid hydrogen a few hundred kilometres down. Below that, there’s pure metallic hydrogen. And somewhere below that there’s a rocky core.’
‘Ana, if they wanted to take apart a planet like this to get at that rocky matter, have you any idea how they might go about it?’
‘I don’t know. Maybe we’re about to find out.’
They hit the transonic boundary. For a moment Thorn thought the ship would break up; that they had finally asked too much of it. The hull had creaked before; now - for an instant - he heard it actively scream. The console flared red and flickered out. For a horrible moment all was silent. Then they were through, ghosting in still air. The console stuttered back into life and a chorus of warning voices began to shriek out of the walls.
‘We’re through,’ Vuilleumier said. ‘In one piece, I think. But let’s not push our luck, Thorn ...’
‘I agree. But now that we’ve come all this way . . . well, it would be silly not to look a little deeper, wouldn’t it?’
‘No.’
‘If you want me to help you, I want to know what I’m getting myself into.’
‘The ship can’t take it.’
Thorn smiled. ‘It just took more crap than you said it would ever be able to take. Stop being such a pessimist.’
The Demarchist representative entered the white holding room and looked at him. Behind her stood three Ferrisville police, the ones he had surrendered to in the departure terminal, and four Demarchist soldiers. The latter had surrendered their firearms but still managed to look foreboding in their fiery red power-armour. Clavain felt old and fragile, knowing that he was completely at the mercy of his new hosts.
‘I am Sandra Voi,’ the woman said. ‘You must be Nevil Clavain. Why did you have me come here, Clavain?’
‘I’m in the process of defecting.’
‘That’s not what I mean. I mean why me in particular? According to the Convention officials you specifically asked for me.’
‘I thought you’d give me a fair hearing, Sandra. I used to know one of your relatives, you see. Who would she have been, your greatgrandmother? I can never get the hang of generations these days.’
The woman pulled up the other white chair and stationed herself in it, opposite Clavain. Demarchists pretended that their political system made rank an outmoded concept. Instead of captains they had shipmasters; instead of generals they had strategic planning specialists. Naturally, such specialisations required visual signifiers, but Voi would have frowned at any suggestion that the many bars and bands of colour across the breast of her tunic indicated anything as outmoded as military status.
‘There hasn’t been another Sandra Voi for four hundred years,’ she said.
‘I know. The last one died on Mars, during an attempt to negotiate peace with the Conjoiners.’
‘You’re talking ancient history now.’
‘Which doesn’t mean it isn’t true. Voi and I were part of the same peacekeeping mission. I defected to the Conjoiners shortly after she died, and I’ve been on their side ever since.’
The eyes of the younger Sandra Voi momentarily glazed over. Clavain’s implants sensed the scurry of data traffic in and out of her skull. He was impressed. Since the plague few Demarchists carried very much in the way of neural augmentation.
