Harry Poole said, ‘You know our business, Jovik. Our wormhole engineering is laying down rapid-transit routes through the System, which will open up a whole family of worlds to colonisation and development. But we have grander ambitions than that.’

I asked, ‘What ambitions? Starships? I read about that.’

‘That and more,’ Michael Poole said. ‘For the last few decades we’ve been working on an experimental ship being built in the orbit of Jupiter . . .’

And he told me about his precious
Cauchy
project
. By dragging a wormhole portal around a circuit light years across, the GUTship
Cauchy
would establish a wormhole bridge – not across space – but across fifteen centuries, to the future. So, having already connected the worlds of humanity with his wormhole subway, Michael Poole now hoped to short-circuit past and future themselves. That, at least, seemed to be the idea. I looked at Poole with new respect, and some fear. The man was a genius, or mad.

‘But,’ I said, ‘to fund such dreams you need money.’

Harry said, ‘Jovik, you need to understand that a mega-engineering business like ours is a ferocious devourer of cash. It’s like the days of the pioneering railway builders back in the nineteenth century. We fund each new project with the profit of our previous ventures and with fresh investment – but that investment depends on the success of earlier schemes.’

‘Ah. And now you’re stumbling. Yes? And this is all to do with Saturn.’

Harry sighed. ‘The Saturn transit was a logical development. The trouble is, nobody needs to go there. Saturn pales beside Jupiter! Saturn has ice moons; well, there are plenty in orbit around Jupiter. Saturn’s atmosphere could be mined, but so can Jupiter’s, at half the distance from Earth.’

Miriam said, ‘Saturn also lacks Jupiter’s ferociously energetic external environment, which we’re tapping ourselves in the manufacture of the
Cauchy
.’

‘Fascinating,’ I lied. ‘You’re an engineer too, then?’

‘A physicist,’ she replied, awkward. She sat next to Michael Poole but apart from him. I wondered if there was anything deeper between them.

‘The point,’ said Harry, ‘is that there’s nothing at Saturn you’d want to go there for – no reason for our expensive wormhole link to be used. Nothing except—’

‘Titan,’ I said.

‘If we can’t go in legally, we need somebody to break us through the security protocols and
get
us down there.’

‘So you turned to me.’

‘The last resort,’ said Bill Dzik with disgust in his voice.

‘We tried your colleagues,’ Miriam said. ‘They all said no.’

‘Well, that’s typical of that bunch of prigs.’

Harry, always a diplomat, smiled at me. ‘So we’re having to bend a few pettifogging rules, but you have to see the vision, man, you have to see the greater good.’

‘Have I? Actually the question is, what’s in it for me? You know I’ve come close to the editing suites before. Why should I take the risk of helping you now?’

‘Because,’ Harry said, ‘if you don’t you’ll
certainly
face a reboot.’ So now we came to the dirty stuff, and Harry took over; he was clearly the key operator in this little cabal, with the engineer types uncomfortably out of their depth. ‘We know about your sideline.’

With a sinking feeling I asked, ‘What sideline?’

And he used his Virtual display to show me. There went one of my doctored probes arrowing into Titan’s thick air, a silver needle that stood out against the murky organic backdrop, supposedly on a routine monitoring mission – but in fact with a quite different objective.

There are pockets of liquid water to be found just under Titan’s surface – frozen-over crater lakes, kept warm for a few thousand years by the residual heat of the impacts that created them. My probe now shot straight through the icy carapace of one of those crater lakes, and into the liquid water beneath. Harry fast-forwarded and we watched the probe’s ascent module push its way out of the lake and up into the air, on its way to my colleagues’ base on Enceladus.

‘You’re sampling the subsurface life from the lakes,’ Harry said sternly. ‘And selling the results.’

I shrugged; there was no point denying it. ‘I guess you know the background. The creatures down there are related to Earth life, but very distantly. Different numbers of amino acids, or something –
I
don’t know. The tiniest samples are gold dust to the biochemists, a whole new toolkit for designer drugs and genetic manipulation . . .’ I had one get-out. ‘You’ll have trouble proving this. By now there won’t be a trace of our probes left on the surface.’ Which was true; one of the many ill-understood aspects of Titan was that probes sent down to its surface quickly failed and disappeared, perhaps as a result of some kind of geological resurfacing.

Harry treated that with the contempt it deserved. ‘We have full records. Samples of the material you stole from Titan. Even a sworn statement by one of your partners.’

I flared at that. ‘Who?’ But, of course, it didn’t matter.

Harry said sweetly, ‘The point is the sheer illegality – and committed by you, a curator, whose job is precisely to guard against such things. If this gets to your bosses, it’s back to the editing suite for you, my friend, and this time even Papa won’t be able to bail you out.’

‘So that’s it. Blackmail.’ I did my best to inject some moralistic contempt into my voice. And it worked; Michael, Miriam, Bill wouldn’t meet my eyes.

But it didn’t wash with Harry. ‘Not the word I’d use. But that’s pretty much it, yes. So what’s it to be? Are you with us? Will you lead us to Titan?’

I wasn’t about to give in yet. I got to my feet. ‘At least let me think about it. You haven’t even offered me that coffee.’

Michael glanced at Harry, who pointed at a dispenser on a stand near my couch. ‘Use that one.’

There were other dispensers in the cabin – why that particular one? I filed away the question and walked over to the dispenser. At a command it produced a mug of what smelled like coffee. I sipped it gratefully and took a step across the floor towards the transparent dome.

‘Hold it,’ Michael snapped.

‘I just want to take in the view.’

Miriam said, ‘
OK
, but don’t touch anything. Follow that yellow path.’

I grinned at her. ‘Don’t
touch
anything? What am I, contagious?’ I wasn’t sure what was going on, but probing away at these little mysteries had to help. ‘Please. Walk with me. Show me what you intend to do here.’

Miriam hesitated for a heartbeat. Then, with an expression of deep distaste, she got to her feet. She was taller than I was, and lithe, strong-looking.

We walked together across the lifedome, a half-sphere a hundred metres wide. Couches, control panels and data entry and retrieval ports were clustered around the geometric centre of the dome; the rest of the transparent floor area was divided up by shoulder-high partitions into lab areas, a galley, a gym, a sleeping area and shower. The layout looked obsessively plain and functional to me. This was the vessel of a man who lived for work, and only that; if this was Michael Poole’s ship, it was a bleak portrait of him.

We reached the curving hull. Glancing down I could see the ship’s spine, a complex column a couple of kilometres long leading to the lode of asteroid ice used for reaction mass by the GUTdrive module within. And all around us wormhole Interfaces drifted like snowflakes, while intra-System traffic passed endlessly through the great gateways.

‘All this is a manifestation of your lover’s vision,’ I said to Miriam, who stood by me.

‘Michael’s not my lover,’ she shot back, irritated. The electric-blue light of the exotic-matter frames shone on her cheekbones.

‘I don’t even know your full name,’ I said.

‘Berg,’ she said reluctantly. ‘Miriam Berg.’

‘Believe it or not, I’m not a criminal. I’m no hero, and I don’t pretend to be. I just want to get through my life, and have a little fun on the way. I shouldn’t be here, and nor should you.’ Deliberately I reached for her shoulder. A bit of physical contact might break through that reserve.

But my fingers
passed through
her flesh, breaking up into a mist of pixels until they were clear of her flesh, and then reformed. I felt a distant ache in my head.

I stared at Miriam Berg. ‘What have you done to me?’

‘I’m sorry,’ she said gravely.

I sat on my couch once more –
my
couch, a Virtual projection like me, the only one in the dome I wouldn’t have fallen through, and sipped a coffee from my Virtual dispenser, the only one that I could touch.

It was, predictably, Harry Poole’s scheme. ‘Just in case the arm-twisting over the sample-stealing from Titan wasn’t enough.’

‘I’m a Virtual copy,’ I said.

‘Strictly speaking, an identity backup . . .’

I had heard of identity backups, but could never afford one myself, nor indeed fancied it much. Before undertaking some hazardous jaunt you could download a copy of yourself into a secure memory store. If you were severely injured or killed, the backup could be loaded into a restored body, or a vat-grown cloned copy, or even allowed to live on in some Virtual environment. You would lose the memories you had acquired after the backup was made, but that was better than non-existence . . . That was the theory. In my opinion it was an indulgence of the rich; you saw backup Virtuals appearing like ghosts at the funerals of their originals, distastefully lapping up the sentiment.

And besides, the backup could never be
you
, the you who had died; only a copy could survive. That was the idea that started to terrify me now. I am no fool, and imaginative to a fault.

Harry watched me taking this in.

I could barely ask the question: ‘What about me? The original. Did I die?’

‘No,’ Harry said. ‘The real you is in the hold, suspended. We took the backup after you were already unconscious.’

So that explained the ache at the back of my neck: that was where they had jacked into my nervous system. I got up and paced around. ‘And if I refuse to help? You’re a pack of crooks and hypocrites, but I can’t believe you’re deliberate killers.’

Michael would have answered, but Harry held up his hand, unperturbed. ‘Look, it needn’t be that way. If you agree to work with us,
you
, the Virtual you, will be loaded back into the prime version. You’ll have full memories of the whole episode.’

‘But I won’t be
me
.’ I felt rage building. ‘I mean, the copy sitting here.
I
won’t exist any more – any more than I existed a couple of hours ago, when you activated me.’ That was another strange and terrifying thought. ‘
I
will have to die! And that’s even if I cooperate. Great deal you’re offering. Well, into Lethe with you. If you’re going to kill
me
anyway I’ll find a way to hurt you. I’ll get into your systems like a virus.
You can’t control me
.’

‘But I can.’ Harry clicked his fingers.

And in an instant everything changed. The four of them had gathered by Harry’s couch, the furthest from me. I had been standing; now I was sitting. And beyond the curved wall of the transparent dome, I saw that we had drifted into Earth’s night.

‘How long?’ I whispered.

‘Twenty minutes,’ Harry said carelessly. ‘You have an off switch. Of course I can control you. So which is it to be? Permanent extinction for all your copies, or survival as a trace memory in your host?’ His grin hardened, and his young-old face was cold.

So the
Hermit Crab
wheeled in space, seeking out the wormhole Interface that led to Saturn. And I, or rather
he
who had briefly believed he was me, submitted to a downloading back into his primary, myself. How ironic that this was a violation of the very sentience protection laws it was my duty to uphold.

He, the identity copy, died to save my life. I salute him.

Released from my cell of suspended animation, embittered, angry, I chose to be alone.

I walked to the very rim of the lifedome, where the transparent carapace met the solid floor. Looking down I could see the flaring of superheated, ionised steam pouring from the GUTdrive nozzles. The engine, as you would expect, was one of Poole’s own designs. ‘
GUT
’ stands for ‘Grand Unified Theory’, which describes the fundamental forces of nature as aspects of a single superforce. This is creation physics. Thus men like Michael Poole use the energies which once drove the expansion of the universe itself for the triviality of pushing forward their steam rockets.

Soon the
Hermit Crab
drove us into the mouth of the wormhole that led to the Saturn system.

We flew lifedome first at the wormhole Interface, so that it was as if the electric-blue tetrahedral frame came down on us from the zenith. Those electric-blue struts were beams of exotic matter, a manifestation of a kind of antigravity field that kept this throat in space and time from collapsing. Every so often you would see the glimmer of a triangular face, a sheen of golden light filtering through from Saturn’s dim halls. It was quite beautiful, a sculpture of light.

The frame bore down, widening in my view, and fell around us, obscuring the view of Earth and Earthport.

Now I was looking up into a kind of tunnel, picked out by flaring sheets of light. This was a flaw in spacetime itself; the flashing I saw was the resolution of that tremendous strain into exotic particles and radiations. As the ship thrust deeper into the wormhole, fragments of blue-white light swam from a vanishing point directly above my head and swarmed down the spacetime walls. There was a genuine sensation of speed, of limitless, uncontrollable velocity. The lifedome creaked like a tin shack, and I thought I could hear that elderly GUTdrive screaming with the strain. I gripped a rail and tried not to cower.

The passage was at least mercifully short. Amid a shower of exotic particles we ascended out of another electric-blue Interface – and I found myself back in the Saturn system, for the first time in years.

I could see immediately that we were close to the orbit of Titan about its primary, for the planet itself, suspended in the scuffed sky of the lifedome, was about the size I remembered it: a flattened globe a good bit larger than the Moon seen from Earth. Other moons hung around the sky, points of light. The sun was off to the right, with its close cluster of inner planets, so Saturn was half-full. Saturn’s only attractive feature, the rings, were invisible, for Titan’s orbit is in the same equatorial plane as the ring system and the rings are edge-on. But the shadow of the rings cast by the sun lay across the planet’s face, sharp and unexpected.

There was nothing romantic in the view, nothing beautiful about it, not to me. The light was flat and pale. Saturn is about ten times as far from the sun as Earth is, and the sun is reduced to an eerie pinpoint, its radiance only a hundredth that at Earth: Saturn is misty and murky, an autumnal place. And you never forgot you were far from home when a human hand, held out at arm’s length towards the sun, could have covered all of the orbit of Earth.

The
Crab
swung about and Titan itself was revealed, a globe choked by murky brown cloud from pole to pole, even more dismal and uninviting than its primary. Evidently Michael Poole had placed his wormhole Interface close to the moon in anticipation that Titan would someday serve his purposes.

Titan was looming larger, swelling visibly. Our destination was obvious.

Harry Poole took charge. He had us put on heavy, thick-layered exosuits of a kind I’d never seen before. We sat on our couches like fat pupae; my suit was so thick my legs wouldn’t bend properly.

‘Here’s the deal,’ Harry said, evidently for my benefit. ‘The
Crab
came out of the wormhole barrelling straight for Titan. That way we hope to get you down there before any of the automated surveillance systems up here can spot us, or do anything about it. In a while the
Crab
will brake into orbit around Titan. But before then you four in the gondola will be thrown straight into an atmospheric entry.’ He snapped his fingers, and a hatch opened up in the floor beneath us to reveal the interior of another craft, mated to the base of the lifedome. This was evidently the ‘gondola’, some kind of landing shuttle. It was like a cave, brightly lit and with its walls crusted with data displays.

I said, ‘“Thrown straight in,” Harry? And what about you?’

He smiled with that young-old face. ‘I will be waiting for you in orbit. Somebody has to stay behind to bail you out, in case.’

‘This “gondola” looks small for the four of us.’

Harry said, ‘Well, weight has been a consideration. You’ll mass no more than a tonne, all up.’ He handed me a data slate. ‘Now this is where you come in, Jovik. I want you to send a covering message to the sentience-law compliance control base on Enceladus.’

I stared at the slate. ‘Saying what, exactly?’

Harry said, ‘The entry profile is designed to mimic an unmanned mission. You’re going in hard, high deceleration. I want you to make yourselves look that way in the telemetry – as if this is just another unmanned probe going in for a bit of science, or a curacy inspection, or whatever it is you bureaucrat types do. Attach the appropriate permissions. I’m quite sure you’re capable of that.’

I was sure of it too. I opened the slate with a wave of my hand, quickly mocked up a suitable profile, let Harry’s systems check I hadn’t smuggled in any cries for help, and squirted it over to Enceladus. Then I handed the slate back. ‘There. Done. You’re masked from the curacy. I’ve done what you want.’ I waved at the looming face of Titan. ‘So you can spare me from
that
, can’t you?’

‘We discussed that,’ said Michael Poole, with just a hint of regret in his voice. ‘We decided to take you along as a fall-back, Jovik, in case of problems, any kind of challenge from Enceladus. Even if they’ve discovered the craft is manned, having you aboard will give us some cover.’

I snorted. ‘They’ll see through that.’

Miriam shrugged. ‘It’s worth it if it buys us a bit more time.’

Bill Dzik stared at me, hard. ‘Just don’t get any ideas, desk jockey. I’ll have my eye on you all the way down and all the way back.’

‘And listen,’ Harry said, leaning forward. ‘If this works out, Jovik, you’ll be rewarded. We’ll see to that. We’ll be able to afford it, after all.’ He grinned that youthful grin. ‘And just think. You will be one of the first humans to walk on Titan! So you see, you’ve every incentive to cooperate, haven’t you?’ He checked a clock on his data slate. ‘We’re close to the release checkpoint. Down you go, team.’

They all sneered at that word, ‘team’, and at the cheerful tone of the man who was staying behind. But we filed dutifully enough through the hatch and down into that cave of instrumentation, Miriam first, then me, and Bill Dzik at my back. Michael Poole was last in; I saw him embrace his father, stiffly, evidently not a gesture they were used to.

In the gondola, our four couches sat in a row, so close that my knees touched Miriam’s and Dzik’s when we were all crammed in there in our suits. The hull was all around us, close enough for me to have reached out and touched it in every direction, a tight-fitting shell. Poole pulled the hatch closed, and I heard a hum and whir as the independent systems of this craft came online. There was a rattle of latches, and then a kind of sideways shove that made my stomach churn. We were already cut loose from the
Crab
, and were falling free, and rotating.

Poole touched a panel above his head, and the hull turned transparent. Now it was as if we four in our couches were suspended in space, surrounded by glowing instrument panels, and blocky masses that must be the power supply, life support, supplies. Above me the
Crab
slid across the face of Saturn, GUTdrive flaring, and below me the orange face of Titan loomed large.

I whimpered. I have never pretended to be brave.

Miriam Berg handed me a transparent bubble-helmet. ‘Lethe, put this on before you puke.’

I pulled the helmet over my head; it snuggled into the suit neck and made its own lock.

Bill Dzik was evidently enjoying my discomfort. ‘You feel safer in the suit, right? Well, the entry is the most dangerous time. But you’d better hope we get through the atmosphere’s outer layers before the hull breaches, Emry. These outfits aren’t designed to work as pressure suits.’

‘Then what use are they?’

‘Heat control,’ Michael Poole said, a bit more sympathetic. ‘Titan’s air pressure is fifty per cent higher than Earth’s, at the surface. But that thick cold air just sucks away your heat. Listen up, Emry. The gondola’s small, but it has a pretty robust power supply – a GUTengine, in fact. You’re going to need that power to keep warm. For short periods your suit will protect you; there are power cells built into the fabric. But you won’t last more than a few hours away from the gondola. Got that?’

I was hardly reassured. ‘What about the entry itself? Your father said we’ll follow an unmanned profile. That sounds . . . vigorous.’

Bill Dzik barked a laugh. Nobody else replied.

Poole and the others began to work through pre-entry system checks. Harry murmured in my ear, telling me that fresh identity backups had just been taken of each of us and stored in the gondola’s systems. I was not reassured.

I lay helpless, trussed up and strapped in, as we plummeted into the sunlit face of Titan.
