A metallic clunk.
   I'm twisting fast. Nerves still hyped. Locking into a karate stance, ready for anything. No use. No fucking use at all.

Jupiter, 2090
A Second Chance at Eden

   The Ithilien decelerated into Jupiter orbit at a constant twentieth of a gee, giving us a spectacular view of the gas giant's battling storm bands as we curved round towards the dark side. Even that's a misnomer, there is no such thing as true darkness down there. Lightning forks whose size could put the Amazon tributary network to shame slashed between oceanic spirals of frozen ammonia. It was awesome, beautiful, and terrifyingly large.
   I had to leave the twins by themselves in the observation blister once Ithilien circularized its orbit five hundred and fifty thousand kilometres out. It took us another five hours to rendezvous with Eden; not only did we have to match orbits, but we were approaching the habitat from a high inclination as well. Captain Saldana was competent, but it was still five hours of thruster nudges, low-frequency oscillations, and transient bursts of low-gee acceleration. I spent the time strapped into my bunk, popping nausea suppressors, and trying not to analogize between Ithilien 's jockeying and a choppy sea. It wouldn't look good arriving at a new posting unable to retain my lunch. Security men are supposed to be unflappable, carved from granite, or some such nonsense anyway.
   Our cabin's screen flicked through camera inputs for me. As we were still in the penumbra I got a better view of the approach via electronically amplified images than eyeballing it from the blister.
   Eden was a rust-brown cylinder with hemispherical endcaps, eight kilometres long, twenty-eight hundred metres in diameter. But it had only been germinated in 2075, fifteen years ago. I talked to Pieter Zernov during the flight from Earth's O'Neill Halo, he was one of the genetics team who designed the habitats for the Jovian Sky Power corporation, and he said they expected Eden to grow out to a length of eleven kilometres eventually.
   It was orientated with the endcaps pointing north/south, so it rolled along its orbit. The polyp shell was smooth, looking more like a manufactured product than anything organic. Biology could never be that neat in nature. The only break in Eden's symmetry I could see were two rings of onion-shaped nodules spaced around the rim of each endcap. Specialist extrusion glands, which spun out organic conductor cables. There were hundreds of them, eighty kilometres long, radiating out from the habitat like the spokes of a bicycle wheel, rotation keeping them perfectly straight. It was an induction system; the cables sliced through Jupiter's titanic magnetosphere to produce all the power Eden needed to run its organs, as well as providing light and heat for the interior.
   «Quite something, isn't it?» I said as the habitat expanded to fill the screen.
   Jocelyn grunted noncommittally, and shifted round under her bunk's webbing. We hadn't exchanged a hundred words in the last twenty-four hours. Not good. I had hoped the actual sight of the habitat might have lightened the atmosphere a little, raised a spark of interest. Twenty years ago, when we got married, she would have treated this appointment with boundless excitement and enthusiasm. That was a big part of her attraction, a delighted curiosity with the world and all it offered. A lot can happen in twenty years, most of it so gradual you don't notice until it's too late.
   I sometimes wonder what traits and foibles I've lost, what attitude I've woven into my own personality. I like to think I'm the same man, wiser but still good-humoured. Who doesn't?
   Eden had a long silver-white counter-rotating docking spindle protruding out from the hub of its northern endcap. Ithilien was too large to dock directly; the ship was basically a grid structure, resembling the Eiffel Tower, wrapped round the long cone of the fusion drive, with tanks and cargo-pods clinging to the structure as if they were silver barnacles. The life-support capsule was a sixty-metre globe at the prow, sprouting thermal radiator panels like the wings of some robotic dragonfly. In front of that, resting on a custom-built cradle, was the seed for another habitat, Ararat, Jupiter's third; a solid teardrop of biotechnology one hundred metres long, swathed in thermal/particle impact protection foam. Its mass was the reason Ithilien was manoeuvring so sluggishly.
   Captain Saldana positioned us two kilometres out from the spindle tip, and locked the ship's attitude. A squadron of commuter shuttles and cargo tug craft swarmed over the gulf towards the Ithilien . I began pulling our flight bags from the storage lockers; after a minute Jocelyn stirred herself and started helping me.
   «It won't be so bad,» I said. «These are good people.»
   Her lips tightened grimly. «They're ungodly people. We should never have come.»
   «Well, we're here now, let's try and make the most of it, OK? It's only for five years. And you shouldn't prejudge like that.»
   «The word of the Pope is good enough for me.»
   Implying it was me at fault, as always. I opened my mouth to reply. But thankfully the twins swam into the cabin, chattering away about the approach phase. As always the façade clicked into place. Nothing wrong. No argument. Mum and Dad are quite happy.
   Christ, why do we bother?

   The tubular corridor which ran down the centre of Eden's docking spindle ended in a large chamber just past the rotating pressure seal. It was a large bubble inside the polyp with six mechanical airlock hatches spaced equidistantly around the equator. A screen above one was signalling for Ithilien arrivals; and we all glided through it obediently. The tunnel beyond sloped down at quite a steep angle. I floated along it for nearly thirty metres before centrifugal force began to take hold. About a fifteenth of a gee, just enough to allow me a kind of skating walk.
   An immigration desk waited for us at the far end. Two Eden police officers in smart green uniforms stood behind it. And I do mean smart: spotless, pressed, fitting perfectly. I held in a smile as the first took my passport and scanned it with her palm-sized PNC wafer. She stiffened slightly, and summoned up a blankly courteous smile. «Chief Parfitt, welcome to Eden, sir.»
   «Thank you,» I glanced at her name disk, «Officer Nyberg.»
   Jocelyn glared at her, which caused a small frown. That would be all round the division in an hour. The new boss's wife is a pain. Great start.
   A funicular railway car was waiting for us once we'd passed the immigration desk. The twins rushed in impatiently. And, finally, I got to see Eden's interior. We sank down below the platform and into a white glare. Nicolette's face hosted a beautiful, incredulous smile as she pressed herself against the glass. For a moment I remembered how her mother had looked, back in the days when she used to smile—I must stop these comparisons.
   «Dad, it's supreme,» she said.
   I put my arm around her and Nathaniel, savouring the moment. Believe me, sharing anything with your teenage children is a rare event. «Yes. Quite something.» The twins were fifteen, and they hadn't been too keen on coming to Eden either. Nathaniel didn't want to leave his school back in the Delph company's London arcology. Nicolette had a boy she was under the impression she was destined to marry. But just for that instant the habitat overwhelmed them. Me too.
   The cyclorama was tropical parkland, lush emerald grass crinkled with random patches of trees. Silver streams meandered along shallow dales, all of them leading down to the massive circumfluous lake which ringed the base of the southern endcap. Every plant appeared to be in flower. Birds flashed through the air, tiny darts of primary colour.
   A town was spread out around the rim of the northern endcap, mostly single-storey houses of metal and plastic moated by elaborately manicured gardens; a few larger civic buildings were dotted among them. I could see plenty of open-top jeeps driving around, and hundreds of bicycles.
   The way the landscape rose up like two green tidal waves heading for imminent collision was incredibly disorientating. Unnerving too. Fortunately the axial light-tube blocked the apex, a captured sunbeam threaded between the endcap hubs. Lord knows what seeing people walking around directly above me would have done to my already reeling sense of balance. I was still desperately trying to work out a viable visual reference frame.
   Gravity was eighty per cent standard when we reached the foot of the endcap, the funicular car sliding down into a plaza. A welcoming committee was waiting for us on the platform; three people and five servitor chimps.
   Michael Zimmels, the man I was replacing, stepped forward and shook my hand. «Glad to meet you, Harvey. I've scheduled a two-hour briefing to bring you up to date. Sorry to rush you, but I'm leaving on the Ithilien as soon as it's been loaded with He3 . The tug crews here, they don't waste time.» He turned to Jocelyn and the twins. «Mrs Parfitt, hope you don't mind me stealing your husband away like this, but I've arranged for Officer Coogan to show you to your quarters. It's a nice little house. Sally Ann should have finished packing our stuff by now, so you can move in straight away. She'll show you where everything is and how it works.» He beckoned one of the officers standing behind him.
   Officer Coogan was in his late twenties, wearing another of those immaculate green uniforms. «Mrs Parfitt, if you'd like to give your flight bags to the chimps, they'll carry them for you.»
   Nicolette and Nathaniel were giggling as they handed their flight bags over. The servitor chimps were obviously genetically adapted; they stood nearly one metre fifty, without any of the rubber sack paunchiness of the pure genotype primates cowering in what was left of Earth's rain forests. And the quiet, attentive way they stood waiting made it seem almost as though they had achieved sentience.
   Jocelyn clutched her flight bag closer to her as one of the chimps extended an arm. Coogan gave her a slightly condescending smile. «It's quite all right, Mrs Parfitt, they're completely under control.»
   «Come on, Mum,» Nathaniel said. «They look dead cute.» He was stroking the one which had taken his flight bag, even though it never showed the slightest awareness of his touch.
   «I'll carry my own bag, thank you,» Jocelyn said.
   Coogan gathered himself, obviously ready to launch into a reassurance speech, then decided chiding his new boss's wife the minute she arrived wasn't good policy. «Of course. Er, the house is this way.» He started off across the plaza, the twins plying him with questions. After a moment Jocelyn followed.
   «Not used to servitors, your wife?» Michael Zimmels asked pleasantly.
   «I'm afraid she took the Pope's decree about affinity to heart,» I told him.
   «I thought that just referred to humans who had the affinity gene splice?»
   I shrugged.

   The Chief of Police's office occupied a corner of the two-storey station building. For all that it was a government-issue room with government-issue furniture, it gave me an excellent view down the habitat.
   «You got lucky with this assignment,» Michael Zimmels told me as soon as the door closed behind us. «It's every policeman's dream posting. There's virtually nothing to do.»
   Strictly speaking I'm corporate security these days, not a policeman. But the Delph company is one of the major partners in the Jovian Sky Power corporation which founded Eden. Basically the habitat is a dormitory town for the He3 mining operation and its associated manufacturing support stations. But even JSKP workers are entitled to a degree of civilian government; so Eden is legally a UN protectorate state, with an elected town council and independent judiciary. On paper, anyway. The reality is that it's a corporate state right down the line; all the appointees for principal civil posts tend to be JSKP personnel on sabbaticals. Like me.
   «There has to be a catch.»
   Zimmels grinned. «Depends how you look at it. The habitat personality can observe ninety-nine per cent of the interior. The interior polyp surface is suffused with clusters of specialized sensitive cells; they can pick up electromagnetic waves, the full optical spectrum along with infrared and ultraviolet; they can sense temperature and magnetic fields, there are olfactory cells, even pressure-sensitive cells to pick up anything you say. All of which means nobody does or says anything that the habitat doesn't know about; not cheating on your partner, stealing supplies, or beating up your boss after you get stinking drunk. It sees all, it knows all. No need for police on the beat, or worrying about gathering sufficient evidence.»
   «Ye gods,» I glanced about, instinctively guilty. «You said ninety-nine per cent? Where is the missing one per cent?»
   «Offices like this, on buildings which have a second floor, where there's no polyp and no servitors. But even so the habitat can see in through the windows. Effectively, the coverage is total. Besides which, this is a company town, we don't have unemployment or a criminal underclass. Making sure the end-of-shift drunks get home OK is this department's prime activity.»
   «Wonderful,» I grunted. «Can I talk to this personality?»
   Zimmels gave his desktop terminal a code. «It's fully interfaced with the datanet, but you can communicate via affinity. In fact, given your status, you'll have to use affinity. That way you don't just talk, you can hook into its sensorium as well, the greatest virtual-reality trip you'll ever experience. And of course, all the other senior executives have affinity symbiont implants—hell, ninety per cent of the population is affinity capable. We use it to confer the whole time, it's a heck of a lot simpler than teleconferencing. And it's the main reason the habitat administration operates so smoothly. I'm surprised the company didn't give you a neuron symbiont implant before you left Earth, you just can't function effectively without one up here.»
   «I told them I'd wait until I got here,» I said, which was almost the truth.
   The terminal chimed melodically, then spoke in a rich male euphonic. «Good afternoon, Chief Parfitt, welcome to Jupiter. I am looking forward to working with you, and hope our relationship will be a rewarding one.»
   «You're the habitat personality?» I asked.
   «I am Eden, yes.»
   «Chief Zimmels tells me you can perceive the entire interior.»
   «That is correct. Both interior and exterior environments are accessible to me on a permanent basis.»
   «What are my family doing?»
   «Your children are examining a tortoise they have found in the garden of your new house. Your wife is talking to Mrs Zimmels, they are in the kitchen.»
   Michael Zimmels raised his eyebrows in amusement. «Sally Ann's cutting her in on the local gossip.»
   «You can see them, too?»
   «Hear and see. Hell, it's boring; Sally Ann's a sponge for that kind of thing. She thinks I don't look after my advancement prospects, so she plays the corporate social ladder game on my behalf.»
   «Do you show anybody anything they ask for?» I asked.
   «No,» Eden replied. «The population are entitled to their privacy. However, legitimate Police Department observation requests override individual rights.»
   «It sounds infallible,» I said. «I can't go wrong.»
   «Don't you believe it,» Zimmels retorted knowingly. «I've just given you the good news so far. You're not just responsible for Eden, the entire JSKP operation in Jupiter orbit comes under your jurisdiction. That means a lot of external work for your squads; the industrial stations, the refineries, inter-orbit ships; we even have a large survey team on Callisto right now.»
   «I see.»
   «But your biggest headache is going to be Boston.»
   «I don't remember that name in any of my preliminary briefings.»
   «You wouldn't.» He produced a bubble cube, and handed it over to me. «This contains my report, and most of it's unofficial. Supposition, plus what I've managed to pick up from various sources. Boston is a group of enthusiasts—radicals, revolutionaries, whatever you want to call them—who want Eden to declare independence, hence the name. They're quite well organized, too; several of their leading lights are JSKP executives, mostly those on the technical and scientific side.»
   «Independence from the UN?»
   «The UN and the JSKP, they want to take over the whole Jupiter enterprise; they think they can create some kind of technological paradise out here, free of interference from Earth's grubby politicians and conservative companies. The old High Frontier dream. Your problem is that engaging in free political debate isn't a crime. Technically, as a UN policeman, you have to uphold their right to do so. But as a JSKP employee, just imagine how the board back on Earth will feel if Eden, Pallas, and Ararat make that declaration of independence, and the new citizens assume control of the He3 mining operation while you're here charged with looking after the corporation's interests.»

   The PNC wafer's bleeping woke me. I struggled to orientate myself. Strange bedroom. Grey geometric shadows at all angles. A motion which nagged away just below conscious awareness.
   Jocelyn shifted around beside me, twisting the duvet. Also unusual, but the Zimmels had used a double bed. Apparently it would take a couple of days to requisition two singles.
   My questing hand found the PNC wafer on the bedside dresser. I prayed I'd programmed it for no visual pick-up before I went to bed. «Call acknowledged. Chief Parfitt here,» I said blearily.
   The wafer hazed over with a moiré rainbow which shivered until a face came into focus. «Rolf Kümmel, sir. Sorry to wake you so early.»
   Detective Lieutenant Kümmel was my deputy, we'd been introduced briefly yesterday. Thirty-two and already well up the seniority ladder. A conscientious careerist, was my first impression. «What is it, Rolf?»
   «We have a major crime incident inside the habitat, sir.»
   «What incident?»
   «Somebody's been killed. Penny Maowkavitz, the JSKP Genetics Division director.»
   «Killed by what?»
   «A bullet, sir. She was shot through the head.»
   «Fuck. Where?»
   «The north end of the Lincoln lake.»
   «Doesn't mean anything. Send a driver to pick me up, I'll be there as soon as I can.»
   «Driver's on her way, sir.»
   «Good man. Wafer off.»

   It was Shannon Kershaw who drove the jeep which picked me up, one of the station staff I'd met the previous afternoon on my lightning familiarization tour, a programming expert. A twenty-eight-year-old with flaming red hair pleated in elaborate spirals; grinning challengingly as Zimmels introduced us. Someone who knew her speciality made her invaluable, giving her a degree of immunity from the usual sharpshooting of office politics. This morning she was subdued, uniform tunic undone, hair wound into a simple tight bun.
   The axial light-tube was a silver strand glimpsed through frail cloud braids high above, slightly brighter than a full Earth moon. Its light was sufficient for her to steer the jeep down a track through a small forest without using the headlights. «Not good,» she muttered. «This is really going to stir people up. We all sort of regarded Eden as . . . I don't know. Pure.»
   I was studying the display my PNC wafer was running, a program correlating previous crime incident files with Penny Maowkavitz, looking for any connection. So far a complete blank. «There's never been a murder up here before, has there?»
   «No. There couldn't be, really; not with the habitat personality watching us the whole time. You know, it's pretty shaken up by this.»
   «The personality is upset?» I enquired sceptically.
   She shot me a glance. «Of course it is. It's sentient, and Penny Maowkavitz was about the closest thing to a parent it could ever have.»
   «Feelings,» I said wonderingly. «That must be one very sophisticated Turing AI program.»
   «The habitat isn't an AI. It's alive, it's conscious. A living entity. You'll understand once you receive your neuron symbiont implant.»
   Great, now I was driving round inside a piece of neurotic coral. «I'm sure I will.»
   The trees gave way to a swath of meadowland surrounding a small lake. A rank of jeeps were drawn up near the shoreline; several had red and blue strobes flashing on top, casting transient stipples across the black water. Shannon parked next to an ambulance, and we walked over to the group of people clustered round the body.
   Penny Maowkavitz was sprawled on the grey shingle four metres from the water. She was wearing a long dark-beige suede jacket over a sky-blue blouse, heavy black cotton trousers, and sturdy ankle boots. Her limbs were askew, the skin of her hands very pale. I couldn't tell how old she was, principally because half of her head was missing. What was left of the skull sprouted a few wisps of fine silver hair. A wig of short-cropped dark-blonde hair lay a couple of metres away, stained almost completely crimson. A wide ribbon of gore and blood was splashed over the shingle between it and the corpse. In the jejune light it looked virtually black.
   Shannon grunted, and turned away fast.
   I'd seen worse in my time, a lot worse. But Shannon was right about one thing, it didn't belong here, not amongst the habitat's tranquillity.
   «When did it happen?» I asked.
   «Just over half an hour ago,» Rolf Kümmel said. «I got out here with a couple of officers as soon as Eden told us.»
   «The personality saw it happen?»
   «Yes, sir.»
   «Who did it?»
   Rolf grimaced, and pointed at a servitor chimp standing passively a little way off. A couple of uniformed officers stood on either side of it. «That did, sir.»
   «Christ. Are you sure?»
   «We've all accessed the personality's local visual memory to confirm it, sir,» he said in a slightly aggrieved tone. «But the chimp was still holding the pistol when we arrived. Eden locked its muscles as soon as the shot was fired.»
   «So who ordered it to fire the pistol?»
   «We don't know.»
   «You mean the chimp doesn't remember?»
   «No.»
   «So who gave it the pistol?»
   «It was in a flight bag, which was left on a polystone outcrop just along the shore from here.»
   «And what about Eden, does it remember who left the bag there?»
   Rolf and some of the others were beginning to look resentful. Lumbered with a dunderhead primitive for a boss, blundering about asking the obvious and not understanding a word spoken. I was beginning to feel isolated, wondering what they were saying to each other via affinity. One or two of them had facial expressions which were changing minutely, visible signs of silent conversation. Did they know they were giving themselves away like that?
   My PNC wafer bleeped, and I pulled it out of my jacket pocket. «Chief Parfitt, this is Eden. I'm sorry, but I have no recollection of who placed the bag on the stone. It has been there for three days, which exceeds the extent of my short-term memory.»
   «OK, thanks.» I glanced round the expectant faces. «First thing, do we know for sure this is Penny Maowkavitz?»
   «Absolutely,» a woman said. She was in her late forties, half a head shorter than everyone else, with dark cinnamon skin. I got the impression she was more weary than alarmed by the murder. «That's Penny, all right.»
   «And you are?»
   «Corrine Arburry, I'm Penny's doctor.» She nudged the corpse with her toe. «But if you want proof, turn her over.»
   I looked at Rolf. «Have you taken the in situ videos?»
   «Yes, sir.»
   «OK, turn her over.»
   After a moment of silence, my police officers gallantly shuffled to one side and let the two ambulance paramedics ease the corpse onto its back. I realized the light was changing, the mock-silver moonlight deepening to a flaming tangerine. Dr Arburry knelt down as the artificial dawn blossomed all around. She tugged the blue blouse out of the waistband. Penny Maowkavitz was wearing a broad green nylon strap around her abdomen, it held a couple of white plastic boxes tight against her belly.
   «These are the vector regulators I supplied,» Corrine Arburry said. «I was treating Penny for cancer. It's her all right.»
   «Video her like this, then take her to the morgue, please,» I said. «I don't suppose we'll need an autopsy for cause of death.»
   «Hardly,» Corrine Arburry said flatly as she rose up.
   «Fine, but I would like some tests run to establish she was alive up until the moment she was shot. I would also like the bullet itself. Eden, do you know where that is?»
   «No, I'm sorry, it must be buried in the soil. But I can give you a rough estimate based on the trajectory and velocity.»
   «Rolf, seal off the area, we need to do that anyway, but I want it searched thoroughly. Have you taken the pistol from the chimp?»
   «Yes, sir.»
   «Do we have a Ballistics Division?»
   «Not really. But some of the company engineering labs should be able to run the appropriate tests for us.»
   «OK, get it organized.» I glanced at the chimp. It hadn't moved, big black eyes staring mournfully. «And I want that thing locked up in the station's jail.»
   Rolf turned a snort into a cough. «Yes, sir.»
   «Presumably we do have an expert on servitor neurology and psychology in Eden?» I asked patiently.
   «Yes.»
   «Good. Then I'd like him to examine the chimp, and maybe try and recover the memory of who gave it the order to shoot Maowkavitz. Until then, the chimp is to be isolated, understood?»
   He nodded grimly.
   Corrine Arburry was smiling at Rolf's discomfort. A sly expression which I thought contained a hint of approval, too.
   «You ought to consider how the gun was brought inside the habitat in the first place,» she said. «And where it's been stored since. If it had ever been taken out of that flight bag the personality should have perceived it and alerted the police straight away. It ought to know who the bag belonged to, as well. But it doesn't.»
   «Was the pistol a police weapon?» I asked.
   «No,» Rolf said. «It's some kind of revolver, very primitive.»
   «OK, run a make, track down the serial number. You know the procedure, whatever you can find on it.»

   The start of the working day found me in the Governor's office. Our official introductory meeting, what should have been a cheery getting-to-know-you session, and I had to report the habitat's first ever murder to him. I tried to tell myself the day couldn't get worse. But I lacked faith.
   The axial light-tube had resumed its usual blaze, turning the habitat cavern into a solid fantasy ideal of tropical wilderness. I did my best to ignore the view as Fasholé Nocord waved me into a seat before his antique wooden desk.
   Eden's governor was in his mid-fifties, with a frame and vigour which suggested considerable genetic adaptation. I've grown adept at recognizing the signs over the years; for a start they all tend to be well educated, because even now it's really only the wealthy who can afford such treatments for their offspring. And health is paramount for them, the treatments always focus on boosting their immunology system, improving organ efficiency, dozens of subtle metabolic enhancements. They possess a presence, almost like a witch's glamour ; I suppose knowing they're not going to fall prey to disease and illness, that they'll almost certainly see out a century, gives them an impeccable self-confidence. Given their bearing, cosmetic adaptation is almost an irrelevance, certainly it's not as widespread. But in Fasholé Nocord's case I suspected an exception. His skin was just too black, the classically noble face too chiselled.
   «Any progress?» he asked straight away.
   «It's only been a couple of hours. I've got my officers working on various aspects; but they aren't used to this type of investigation. Come to that, there's never been a large-scale police investigation in Eden before. With the habitat's all-over sensory perception there's been no need until today.»
   «How could it happen?»
   «You tell me. I'm not an expert on this place yet.»
   «Get a symbiont implant. Today. I don't know what the company was thinking of, sending you out here without one.»
   «Yes, sir.»
   His lips twitched into a rueful grin. «All right, Harvey, don't go all formal on me. If ever I needed anyone on my side, then it's you. The timing of this whole thing stinks.»
   «Sir?»
   He leant forward over the desk, hands clasped earnestly. «I suppose you realize ninety per cent of the population suspect I have something to do with Penny's murder?»
   «No,» I said cautiously. «Nobody's told me that.»
   «Figures,» he muttered. «Did Michael brief you on Boston?»
   «Yes, the salient points; I have a bubble cube full of files which he compiled, but I haven't got round to accessing any of them yet.»
   «Well, when you do, you'll find that Penny Maowkavitz was Boston's principal organizer.»
   «Oh, Christ.»
   «Yeah. And I'm the man responsible for ensuring Eden stays firmly locked in to the JSKP's domain.»
   I remembered his file; Nocord was a vice-president (on sabbatical) from McDonnell Electric, one of the JSKP's parent companies. Strictly managerial and administration track, not one of the aspiring dreamers, someone the board could trust implicitly.
   «If we can confirm where you were prior to the murder, you should be in the clear,» I said. «I'll have one of my officers take a statement and correlate it with Eden's memory of your movements. Shouldn't be a problem.»
   «It would never be me personally, anyway, not even as part of a planning team. JSKP would use a covert agent.»
   «But clearing your name quickly would help quell any rumours.» I paused. «Are you telling me JSKP takes Boston seriously enough to bring covert operatives into this situation?»
   «I don't know. I mean that, I'm not holding out on you. As far as I know the board is relying on you and me to prevent things from getting out of control up here. We know you're dependable,» he added, almost in apology.
   I guess he'd studied my file as closely as I'd gone over his. It didn't particularly bother me. Anyone who does access my history isn't going to find any earthshaker revelations. I used to be a policeman, I went into the London force straight from university. With thirty-five million people crammed together in the Greater London area, and four million of them unemployed, policing is a very secure career, we were in permanent demand. I was good at it, I made detective in eight years. Then my third case was working as part of a team investigating corruption charges in the London Regional Federal Commission. We ran down over a dozen senior politicians and civil servants receiving payola for awarding contracts to various companies. Some of the companies were large and well known, and two of the politicians were sitting in the Greater Federal Europe congress. Quite a sensation, we were given hours of prime facetime on the newscable bulletins.
   The judge and the Metropolitan Police Commander congratulated us in front of the cameras, handshakes and smiles all round. But in the months which followed none of my colleagues who went up before promotion boards ever seemed successful. We got crappy assignments. We pulled the night shifts for weeks at a time. Overtime was denied. Expenses were queried. Call me cynical, I quit and went into corporate security. Companies regard employee loyalty and honesty as commendable traits—below board level anyway.
   «I like to think I am, yes,» I told the Governor. «But if you're expecting trouble soon, just remember I haven't had time to build any personal loyalties with my officers. What did you mean that the murder's timing stinks?»
   «It looks suspicious, that's all. The company sends a new police chief who isn't even affinity capable; and, wham , Penny is murdered the day after you arrive. Then there's the cloudscoop lowering operation in two days' time. If it's successful, He3 extraction will become simpler by orders of magnitude, decreasing Jupiter's technological dependence on Earth. And the Ithilien delivered the Ararat seed; another habitat, safeguarding the population if we do ever have a major environmental failure in Eden or Pallas. It's a good time for Boston to try and break free. Ergo, killing the leader is an obvious option.»
   «I'll bear it in mind. Do you have any ideas who might have killed her?»
   Fasholé Nocord sat back in his chair and grinned broadly. «Real police are never off the case, eh?»
   I returned a blank smile. «You have been emphasizing your own innocence with a great deal of eloquence.»
   It wasn't quite the response he was looking for. The professional grin faltered. «No, I don't have any idea. But I will tell you Penny Maowkavitz was not an easy person to work with; if pushed I'd describe her as stereotypically brash. She was always convinced everything she did was right. People who didn't agree with her were more or less ignored. Her brilliance allowed her to get away with it, of course; she was vital to the initial design concept of the habitats.»
   «She had her own biotechnology company, didn't she?»
   «That's right, she founded Pacific Nugene; it's basically a softsplice house, specializing in research and design work rather than production. Penny preferred to deal in concepts; she refined the organisms until they were viable, then licensed out the genome to the big boys for actual manufacture and distribution. She was the first geneticist JSKP approached when it became obvious we needed a large dormitory station in Jupiter orbit. Pacific Nugene was pioneering a microbe which could digest asteroid rock; initially the board wanted to use those microbes to hollow out a biosphere cavern in one of the larger ring particles. It would be a lot cheaper than shipping mining teams and all their equipment out here. Penny proposed they use a living polyp habitat instead, and Pacific Nugene became a minor partner in JSKP. She was a board member herself up until five years ago; even after she gave up her seat she retained a non-executive position as senior biotechnology adviser.»
   «Five years ago?» I took a guess. «That would be when Boston formed, would it?»
   «Yes,» he sighed. «Let me tell you, the JSKP board went ballistic. They considered Penny's involvement as a total betrayal. Nothing they could do about it, of course, she was essential to develop the next generation of habitats. Eden is really only a prototype.»
   «I see. Well, thanks for filling me in on the basics. And if you do remember anything relevant . . .»
   «Eden will remember anyone she ever argued with.» He shrugged, his hands splaying wide. «You really will have to get a symbiont implant.»
   «Right.»

   I drove myself back to the station, sticking to a steady twenty kilometres an hour. The main road of naked polyp which ran through the centre of the town was clogged with bicycle traffic.
   Rolf Kümmel had set up an incident room on the ground floor. I didn't even have to tell him; like me he'd been a policeman at one time, four years in a Munich arcology. I walked in to a quiet bustle of activity. And I do mean quiet, I could only hear a few excitable murmurs above the whirr of the air conditioning. It was eerie. Uniformed officers moved round constantly between the desks, carrying fat files and cases of bubble cubes; maintenance techs were still installing computer terminals on some desks, their chimps standing to attention beside them, holding toolboxes and various electronic test rigs. Seven shirtsleeved junior detectives were loading data into working terminals under Shannon Kershaw's direction. A big hologram screen on the rear wall displayed a map of Eden's parkland. Two narrow lines—one red, one blue—were snaking across the countryside like newborn neon streams. They both originated at the Lincoln lake, which was about a kilometre south of town.
   Rolf was standing in front of the screen, hands on hips, watching attentively as the lines lengthened.
   «Is that showing Penny Maowkavitz's movements?» I enquired.
   «Yes, sir,» Rolf said. «She's the blue line. And the servitor chimp is red. Eden is interfaced with the computer; this is a raw memory plot downloaded straight from its neural strata. It should be able to tell us everyone who came near the servitor in the last thirty hours.»
   «Why thirty hours?»
   «That's the neural strata's short-term memory capacity.»
   «Right.» I was feeling redundant and unappreciated again. «What was the servitor chimp's assigned task?»
   «It was allotted to habitat botanical maintenance, covering a square area roughly two hundred and fifty metres to a side, with the lake as one border. It pruned trees, tended plants, that kind of thing.»
   I watched the red line lengthening, a child's crayon-squiggle keeping within the boundary of its designated area. «How often does it . . . go back to base?»
   «The servitor chimps are given full physiological checks every six months in the veterinary centre. The ones allotted to domestic duties have a communal wash-house in town where they go to eat, and keep themselves clean. But one like this . . . it wouldn't leave its area unless it was ordered to. They eat the fruit, their crap is good fertilizer. If they get very muddy they'll wash it off in a stream. They even sleep out there.»
   I gave the screen a thoughtful look. «Did Penny Maowkavitz take a walk through the habitat parkland very often?»
   He rewarded me a grudgingly respectful glance. «Yes, sir. Every morning. It was a kind of an unofficial inspection tour, she liked to see how Eden was progressing; and Davis Caldarola said she used the solitude to think about her projects. She spent anything up to a couple of hours rambling round each day.»
   «She walked specifically through this area around Lincoln lake?»
   His eyelids closed in a long blink. A green circle started flashing over one of the houses on the parkland edge of the town. «That's her house; as you can see it's in the residential zone closest to Lincoln lake. So she would probably walk through this particular chimp's area most mornings.»
   «Definitely not a suicide, then; the chimp was waiting for her.»
   «Looks that way. It wasn't a random killing, either. I did think the murderer might have simply told the chimp to shoot the first person it saw, but that's pretty flimsy. Whoever primed that chimp put a lot of preparation into this. If all you want to do is kill someone, there are much easier ways.»
   «Yes.» I gave an approving nod. «Good thinking. Who's Davis Caldarola?»
   «Maowkavitz's lover.»
   «He knows?»
   «Yes, sir.»
   The «of course» was missing from his voice, but not his tone. «Don't worry, Rolf, I'm getting my symbiont implant this afternoon.»
   He struggled against a grin.
   «So what else have we come up with since this morning?»
   Rolf beckoned Shannon Kershaw over. «The gun,» he said. «We handed it over to a team from the Cybernetics Division's precision engineering laboratory. They say it's a perfect replica of a Colt .45 single-action revolver.»
   «A replica?»
   «It's only the pistol's physical template which matches an original; the materials are wrong,» Shannon said. «Whoever made it used boron-reinforced single-crystal titanium for the barrel, and berylluminium for the mechanism, even the grip was moulded from monomolecule silicon. That was one very expensive pistol.»
   «Monomolecule silicon?» I mused. «That can only be produced in microgee extruders, right?»
   «Yes, sir.» She was becoming animated. «There are a couple of industrial stations outside Eden with the necessary production facilities. I think the pistol was manufactured and assembled in the habitat itself. Our Cybernetics Division factories could produce the individual components without any trouble; and all the exotic materials are available as well. I checked.»
   «It would go a long way to explaining why Eden never saw the pistol before,» Rolf said. «Separately, the components wouldn't register as anything suspicious. Then after manufacture they could have been put together in one of the areas where the habitat personality doesn't have total perception coverage. I'd say that was easier than trying to smuggle one through our customs inspection; we're pretty thorough.»
   I turned to Shannon. «So we need a list of everyone authorized to use the cyberfactories, and out of that we need those qualified or capable of running up the Colt's components without anyone else realizing or querying what they were doing.»
   «I'm on it.»
   «Any other angles?»
   «Nothing yet,» Rolf said.
   «What about a specialist to examine the chimp?»
   «Hoi Yin was recommended by the habitat Servitor Department, she's a neuropsychology expert. She said she'll come in to study it this afternoon. I'll brief her myself.»
   «But you must be very busy, Rolf,» Shannon said silkily. «I can easily spare the time to escort her.»
   «I said I'd do it,» he said stiffly.
   «Are you quite sure?»
   «OK,» I told them. «That'll do.» I clapped my hands, and raised one arm until I had everyone's attention. «Good morning, people. As you ought to know by now, I'm Chief Harvey Parfitt, your new boss. I wish we could have all had a better introduction, Christ knows I didn't want to start with this kind of pep talk. However . . . there are a lot of rumours floating round Eden concerning Penny Maowkavitz's murder. Please remember that they are just that, rumours. More than anyone, we know how few facts have been established. And I expect police officers under my command to concentrate on facts. It's important for the whole community that we solve this murder, preferably with some speed; the habitat residents must have confidence in us, and we simply cannot allow this murderer to walk around free, perhaps to kill again.
   «As to the investigation itself; as Eden's personality seems unable to assist us at this point, our priority is to search back through Penny Maowkavitz's life, both private and professional, to establish some kind of motive for the murder. I want a complete profile assembled on her physical movements going back initially for a week, after that we'll see if it needs extending any further. I want to know where she went, who she met, what she talked about. On top of that I want any long-time antagonisms and enemies listed. Draw up a list of friends and colleagues to interview. Remember, no detail is too trivial. The reason for her death is out there somewhere.» I looked round the dutifully attentive faces. «Can anyone think of a line of inquiry I've missed?»
   One of the uniformed officers raised her hand.
   «Yes, Nyberg.»
   If she was embarrassed that I remembered her name, she didn't show it. «Penny Maowkavitz was rich. Someone must inherit Pacific Nugene.»
   «Good point.» I'd wondered if they'd mention that. Once you can get them questioning together, working as a team in your presence, you've won half the battle for acceptance. «Shannon, get a copy of Maowkavitz's will from her lawyer, please. Anything else? No. Good. I'll leave you to get on with it. Rolf will hand out individual assignments; including someone to take a statement from the Governor about his whereabouts over the last few days. Apparently we have one or two conspiracy theorists to placate.» Several knowing grins flashed round the room. Rolf let out a dismayed groan.
