  ‘You did your best,’ I said, a hand on Dieterling’s shoulder.

  Cahuella looked down at the body of Vicuna with unconcealed fury. ‘Typical of that bastard to die on us before we could use him properly. How the hell are any of us going to be able to put those implants into a snake?’

  ‘Maybe catching the snake isn’t our absolute top priority now,’ I said.

  ‘You think I don’t know that, Tanner?’

  ‘Then try acting like it.’ He glared at me for my insubordination, but I continued anyway, ‘I didn’t like Vicuna, but he risked his life for you.’

  ‘And whose fucking fault was it that Rodriguez was an impostor? I thought you screened your recruits, Mirabel.’

  ‘I did screen him,’ I said.

  ‘Meaning what?’

  ‘The man I killed couldn’t have been Rodriguez. Vicuna seemed to agree with me, too.’

  Cahuella looked at me as if I was something he had found stuck to the bottom of his shoe, then stormed out, leaving me alone with Dieterling.

  ‘Well?’ he said. ‘I hope you have some idea what happened out there, Tanner.’ He pulled a sheet over the dead Vicuna, then began to gather up the neatly glistening surgical tools.

  ‘I don’t. Not yet. It was Rodriguez . . . at least it looked like him.’

  ‘Try calling the Reptile House again.’

  He was right; it was an hour since I had last tried, and I had not been able to get a call through then. As always, the girdle of comsats around Sky’s Edge was patchy and subject to constant military interference, elements mysteriously breaking down and coming back online for the nefarious purposes of other factions.

  This time, however, the link worked.

  ‘Tanner? You’re all okay?’

  ‘More or less.’ I would elaborate on our loss later; for now I needed to know what Doctor Vicuna had been told. ‘What was the warning you relayed to us about Rodriguez?’

  The man I was dealing with was called Southey; someone I had known for years. But I had never seen him look as disconcerted as he did now. ‘Tanner, I hope to God . . . we got a warning ourselves, from one of Cahuella’s allies. A tip-off about Rodriguez.’

  ‘Go on.’

  ‘Rodriguez is dead! They found his body in Nueva Santiago. He’d been murdered, then dumped.’

  ‘You’re sure it was him?’

  ‘We have his DNA on file. Our contact in Santiago ran an analysis on the body - it was a one-to-one match.’

  ‘Then the Rodriguez who came back from Santiago must have been someone else, is that what you’re saying?’

  ‘Yes. Not a clone, we think, but an assassin. He would have been surgically modified to look like Rodriguez; even his voice and smell must have been altered.’

  I thought about that for a few moments before replying, ‘There’s no one on Sky’s Edge with the skill to do something like that. Especially not in the few days that Rodriguez was away from the Reptile House.’

  ‘No, I agree. But the Ultras could have done it.’

  That much I knew, Orcagna having practically rubbed our faces in his superior science. ‘It would have to be more than just cosmetic,’ I said.

  ‘What do you mean?’

  ‘Rodriguez - the impostor - still behaved like himself. He knew things only Rodriguez really knew. I know - I talked to him often in the last few days.’ Now that I considered those conversations, there had at times been something evasive about Rodriguez, but obviously nothing serious enough to rouse my suspicions at the time. There had been much that he had been perfectly willing to discuss.

  ‘So they used his memories as well.’

  ‘You think they trawled Rodriguez?’

  Southey nodded. ‘It must have been done by experts, because there was no sign that it was the trawl itself that killed him. But again, they were Ultras.’

  ‘And you think they have the means to implant the memories into their assassin?’

  ‘I’ve heard of such things,’ Southey said. ‘Tiny machines which swarm through the subject’s mind, laying down new neural connections. Eidetic imprinting, they call it. The NCs tried it for training purposes, but they never got it to work really well. But if Ultras were involved . . .’

  ‘It would have been child’s play. It wasn’t just that the man had access to Rodriguez’s memories, though - it went deeper than that. Like he had almost become Rodriguez in the process.’

  ‘Maybe that’s why he was so convincing. Those new memory structures would have been fragile, though - the assassin’s own personality would have begun to emerge sooner or later. But by then Rodriguez would have gained your confidence.’

  Southey was right: it was only in the last day or so that Rodriguez had seemed more than usually evasive. Was that the point when the assassin’s buried mind began to shine through the veil of camouflaging memories?

  ‘He gained it pretty well,’ I said. ‘If it wasn’t for Vicuna warning us . . .’ I told him about what had happened around the tree.

  ‘Bring the bodies back,’ Southey said. ‘I want to see how well they really disguised their man - whether it was cosmetic, or whether they tried to change his DNA as well.’

  ‘You think they went to that much trouble?’

  ‘That’s the point, Tanner. If they went to the right kind of people, it wouldn’t have been much trouble at all.’

  ‘To the best of my knowledge, there’s only one group of Ultras in orbit around the planet at the moment.’

  ‘Yes. I’m fairly sure that Orcagna’s people must have been involved in this. You met them, didn’t you? Did you think they could be trusted?’

  ‘They were Ultras,’ I said, as if that were answer enough. ‘I couldn’t read them like one of Cahuella’s usual contacts. That doesn’t mean they’d automatically betray us, though.’

  ‘What would they have to gain by not betraying us?’

  That, I realised, was the one question I had never really asked. I had made the error of treating Orcagna like any other of Cahuella’s business contacts - someone who would not want to exclude dealing with Cahuella again in the future. But what if Orcagna’s crew had no intention of returning to Sky’s Edge for decades, even centuries? They could burn all their bridges with impunity.

  ‘Orcagna might not have known that the assassin was aimed at us,’ I said. ‘Someone affiliated to Reivich just presented them with a man who needed his appearance changed; another man who needed his memories transferred into the first . . .’

  ‘And you think it didn’t even occur to Orcagna to ask questions? ’

  ‘I don’t know,’ I said, even my own argument sounding weak.

  Southey sighed. I knew what he was thinking. It was what I was thinking myself. ‘Tanner, I think we need to play it very carefully from here on in.’

  ‘At least one good thing’s come out of it,’ I said. ‘Now that the doctor’s dead, Cahuella’s had to abandon his snake quest. He just hasn’t realised it yet.’

  Southey forced a thin smile. ‘We’ve already dug half the new pit.’

  ‘I wouldn’t worry about finishing the rest by the time we get back.’ I paused and checked the map again, the blinking dot which represented Reivich’s progress. ‘We’ll camp again tonight, about sixty klicks north of here. Tomorrow we’ll be on our way home.’

  ‘Tonight’s the night?’

  With Rodriguez and the doctor dead, we would be undermanned when it came to the ambush. But there would be still be enough of us to make victory a near-mathematical certainty.

  ‘Tomorrow morning. Reivich should enter our trap two hours before noon, if he maintains his progress.’

  ‘Good luck, Tanner.’

  I nodded and closed the connection with the Reptile House. Outside, I found Cahuella and told him what I had learned from Southey. Cahuella had calmed down a little since our last conversation, while his men worked around us packing up the rest of the camp. He was strapping a black leather bandolier from waist to shoulder, with numerous little
leather pockets for cartridges, clips, ammo-cells and other paraphernalia.

  ‘They can do that kind of shit as well? Memory transfer?’

  ‘I’m not sure how permanent it would have been, but - yes - I’m reasonably sure they could have trawled Rodriguez so that Reivich’s man had enough of his knowledge not to arouse our suspicions. You’re less surprised that they could change his shape so convincingly?’

  He seemed unwilling to answer me immediately. ‘I know they can . . . change things, Tanner.’

  There were times when I felt I knew Cahuella as well as anyone; that at times we were as close as brothers. I knew him to be capable of a cruelty more imaginative and instinctive than anything I could devise. I had to work at being cruel, like a hard-working musician who lacked the easy, virtuoso flair of the true-born genius. But we saw things similarly, judged people with the same jaundiced eye and were both possessed of an innate skill with weapons. Yet there were times, like now, that it was as if Cahuella and I had never met; that there were infinite secrets he would never share with me. I thought back to what Gitta had told me the night before; her implication that what I knew about him was only the tip of the iceberg.

  An hour later and we were on our way, with the two bodies - Vicuna and the bipartite Rodriguez - in refrigerated coffins, stowed in the last vehicle. The hard-shelled coffins had doubled as rations stores until now. Predictably enough, the hunting trip no longer felt like much of a holiday. I had never seen it like that, of course, but Cahuella certainly had, and I could read the tension in the muscles of his neck as he strained to look forward along the trail. Reivich had been a step ahead of us.

  Later, when we stopped to fix a turbine, he said, ‘I’m sorry I blamed you back there, Tanner.’

  ‘I’d have done the same.’

  ‘That’s not the point, is it? I trust you like a brother. I did and I still do. You saved us all when you killed Rodriguez.’

  Something green and leathery flapped over the road. ‘I prefer not to think of that impostor as Rodriguez. Rodriguez was a good man.’

  ‘Of course . . . it was just verbal shorthand. You - um - don’t think there are likely to be any more of them, do you?’

  I had given the matter some thought. ‘We can’t rule it out, but I don’t think it’s very likely. Rodriguez had come back from a trip, whereas everyone else on the expedition hasn’t left the Reptile House for weeks - apart from you and me, of course, when we visited Orcagna. I think we can remove ourselves from suspicion. Vicuna might have been a possibility, but he’s neatly removed himself as well.’

  ‘All right. One other thing.’ He paused, casting a wary eye over his men as they hammered at something under an engine cowling with what looked like less than professional care. ‘You don’t think that might have actually been Reivich, do you?’

  ‘Disguised as Rodriguez?’

  Cahuella nodded. ‘He did say he was going to get me.’

  ‘Yes . . . but my guess is he’s with the main party. That’s what Orcagna told us. The imposter might even have planned to lie low with us, not compromising his cover until the rest of the party came through.’

  ‘It could have been him, though.’

  ‘I don’t think so; not unless the Ultras are even cleverer than we thought. Reivich and Rodriguez were nowhere near the same size. I can believe they altered his face, but I can’t see them having the time to change his entire skeleton and musculature - not in a few days. Then they’d still have to adjust his body-image so he didn’t keep bumping into ceilings. No; their assassin must have been a man of similar build to Rodriguez.’

  ‘It’s possible he got a warning through to Reivich, though?’

  ‘Possible, yes - but if he did, Reivich isn’t acting on it. The weapons traces are still moving at the normal rate towards us.’

  ‘Then - essentially - nothing’s changed, right?’

  ‘Essentially nothing,’ I said, but we both knew that neither of us felt it.

  Shortly afterwards his men made the turbine sing again and we were on our way. I had always taken the security of the expedition seriously, but now I had redoubled my efforts and rethought all my arrangements. No one was leaving camp unless they were armed, and no one was to leave alone - except, of course, for Cahuella himself, who would still insist on his nocturnal prowls.

  The camp we set tonight would form the basis of our ambush, so I was determined to spend more than the usual amount of time searching for the best place to pitch the bubbletents. The camp had to be nearly invisible from the road, but close enough that we could mount an attack on Reivich’s group. I did not want us to become too separated from our munitions stores, which meant placing the tents no more than fifty or sixty metres into the trees. Before nightfall, we could scythe out strategic lines of fire through the wood and arrange fall-back routes for ourselves in case Reivich’s men laid down a heavy suppressing fire. If time allowed we would set deadfalls or mines along other, more obvious paths.

  I was drawing a map in my mind, crisscrossing it with intersecting lines of death, when the snake began to cross our path.

  My attention had wandered slightly from the route ahead, so it was Cahuella shouting ‘Stop!’ which first alerted me that something was happening.

  Turbines cut; our vehicles bellied down.

  Two or three hundred metres down the trail, just where the trail began to curve out of sight, the hamadryad had poked its head out of the curtain of greenery which marked the edge of the jungle. The head was a pale, sickly green, under the olive folds of its photosensitive cowl, retracted like a cobra’s hood. It was crossing from right to left; towards the sea.

  ‘Near-adult,’ Dieterling said, as if what we were looking at was a bug stuck to the windshield.

  The head was nearly as big as one of our vehicles. Behind it came the first few metres of the creature’s snakelike body. The patterning was the same as I had seen on the helical structure wrapped around the hamadryad tree, very snakelike.

  ‘How big do you think it is?’ I asked.

  ‘Thirty, thirty-five metres. Not the biggest I’ve ever seen - that has to be a sixty-metre snake I saw back in ’71 - but this isn’t any juvenile. If it can find a tree which reaches the canopy and isn’t much higher than its length, it’ll probably begin fusion.’

  The head had reached the other side of the road. It moved slowly, creeping past us.

  ‘Take us closer,’ Cahuella said.

  ‘Wait,’ I said. ‘Are you sure? We’re safe here. It’ll pass soon. I know they don’t have any deeply wired defensive instincts, but it might still decide we look like something worth eating. Are you sure you want to risk that?’

  ‘Take us closer.’

  I fired up the turbine, gunning it to the minimum number of revs sufficient to give us lift, and crept the vehicle forward. Hamadryads were thought to have no sense of sound, but seismic vibrations were another thing entirely. I wondered whether the air-cushion of our car, drumming against the ground, sounded exactly like part of the snake’s diet coming closer.

  The snake had arced itself so that the length of two-metre-thick body spanning the road was always elevated. It continued to move slowly and smoothly, betraying absolutely no sign that it had even registered our presence. Perhaps Dieterling was right. Perhaps all the snake was interested in was finding a nice tall tree to curl itself around, so that it could give up this tedious business of having a brain and having to move around.

  We were fifty metres from it now.

  ‘Stop,’ Cahuella said again.

  This time I obeyed unquestioningly. I turned to look at him, but he was already hopping out of the car. We could hear the snake now: a constant low rumble as it pushed itself through foliage. It was not an animal sound at all. What it sounded like was the continuous crunching progress of a tank.

  Cahuella reappeared at the side of the vehicle. He had gone round the back to where the weapons were stored and had drawn out his crossbow.

  ‘Oh, no
. . .’ I started to say, but it was too late.

  He was already racking a tranquilliser dart into the bow, coded for use against a thirty-metre adult. The weapon, on the face of it, seemed like an affectation, but it made a kind of sense. A huge quantity of tranquilliser would have to be delivered to an adult to dope it as we had the juvenile. Our normal hunting rifles were just not up to the job. A crossbow, on the other hand, could fire a much larger dart - and the apparent drawbacks of limited range and accuracy were hardly relevant when one was dealing with a deaf and blind thirty-metre snake which took a minute to move its body length.

  ‘Shut up, Tanner,’ Cahuella said. ‘I didn’t come out here to see one of these bastards and turn away from it.’

  ‘Vicuna’s dead. That means we have no one to implant those control electrodes.’

  It was as if I had not spoken. He set off down the trail, the crossbow in one hand, the muscles in his muscular back defined against the sweat-sodden shirt he wore under his bandolier.

  ‘Tanner,’ Gitta said. ‘Stop him, before he gets hurt.’

  ‘He’s not in any real danger . . .’ I started to say.

  But it was a lie, and I knew it. He might have been safer than if he had been this close to a juvenile, but the behaviour of near-adults was only poorly understood. Swearing, I opened the door on my side, jogged round to the back of the vehicle and unracked a laser-rifle for myself. I checked the ammo-cell’s charge, then loped after him. Hearing my footfalls against the dirt, Cahuella looked back irritatedly.

  ‘Mirabel! Get the hell back into the car! I don’t want anyone ruining this kill for me!’
