Yes, sir.

Shannon, how are you doing on accessing Maowkavitz's computer files?

Some progress, boss.she gave me a thumbs-up from behind her terminal, then ducked her head down again. I've recovered about twenty per cent of the files stored in her home system. It's all been genetic work so far, beyond me. Rolf said to turn it over to Pacific Nugene for assessment. I haven't heard anything back from them yet. Those files were fairly easy to crack. But there's a whole series of files which use a much higher level of entry encryption techniques; stuff she didn't leave any keys for, not even in her will. That's real strange, because the files are quite large. They obviously contain a lot of work.

OK, prioritize that, please, I want to know what's in them. Today if possible.

Her head came up again, giving me a martyred look. I'm organizing some decryption architecture now.

Good grief, an officer with initiative. Whatever next?

An officer with decent pay, she shot back.

I gave up. Any luck with the bag which the pistol was left in?i asked rolf.

No. It's a standard issue flight bag, made in Australia, been in production for six years. JSKP distributes them to every family which is given an assignment here, they're automatically included with the cargo pods we're sent to pack everything in. Ninety per cent of the habitat population have one sitting at home somewhere. Impossible to trace. The medical lab at the hospital ran some forensic tests on it for us. No fingerprints, naturally. It had been wiped with a paper tissue; they found traces of the fibre, identified as a domestic kitchen towel. They also found some hair which they confirm came from the chimp. But nothing to tell us who put it there.

Nobody said it was going to be easy, Rolf.i made an effort not to show how worried i was becoming. two days of solid investigation, with a fairly dedicated team putting in a lot of effort, and we were still no nearer to solving it than we were the minute maowkavitz was killed. that wasn't good. a worldlet where surveillance is total, an effective organization for collecting and correlating data. and nothing . Nobody was that good. There is no such thing as a professional murderer. Sure, you get assassins, snipers, contract killers; but like I told Nathaniel, I didn't believe this was a paid hit. This was an act of vengeance, or revenge, or—remote possibilities—passion and jealousy. A one-off, planned in isolation.

That means a mistake was made. You cannot cover everything, every angle, because at the very heart of the crime lies your reason to murder. Once the police have that, they have you, no matter how well you camouflage your tracks with regards to the method.

And with all I knew, I couldn't think of a reason why anyone in Eden would want to kill Penny Maowkavitz. Nobody I'd spoken to had actually admitted to liking her, but everyone respected her, it was like one of those universal constants.

The only person left who could conceivably cast any light on the problem was Davis Caldarola. I'd held off interviewing him out of an old-fashioned sense of sympathy; according to Zimmels's ubiquitous files he and Penny had been together for seven years, her death would have hit him hard. He had certainly looked pretty shaken up when I glimpsed him at the funeral.

Sorry, Davis.

Rolf drove the jeep down to the southern endcap, taking one of the five equidistantly spaced roads which ran the length of the habitat. A tram monorail ran down the outside of each lane. Two of the automatic vehicles passed us, coming in the opposite direction; bullet-nosed aluminium cylinders painted a bright yellow. They had seats for forty passengers, although I only saw five or six people using them. I couldn't work out why they'd been streamlined, either; their top speed was only forty-five kilometres an hour. Something Victorian would have been more appropriate, more pleasing to the eye as well. But that's modern designers for you, image junkies.

We were halfway to the cyberfactory when the Governor called me. It was like a sixth sense made real; I knew someone wanted to talk to me, swiftly followed by a subliminal image of Fashol

Yes, Governor?

About time you became affinity capable, he said. his mind-tone was as grumpy as his voice. How is the investigation going?

I sent you a progress update file last night, sir.

Yes, I accessed it. It's not what I'd call progress. You haven't found shit so far.

It's only been two days, sir.

Look, Harvey, I've got the board breathing acid fire down my neck. The newscable reporters are jamming half the uplinks from Earth demanding statements. Even the Secretary General's office is pressing for a result; they want to show how efficient and relevant the UN's administration of Eden is. I've got to have something to tell them all.

What can I say, enquiries are continuing.

Damn it, Harvey, I've given you time without any pressure; now I want results. Have you even got a suspect yet?

No, sir, I haven't. Perhaps you'd care to take charge of the investigation yourself if you're that dissatisfied with my progress.

Don't try pulling that smartarse routine on me, Harvey, it doesn't work. Come on, man, you should have some kind of lead by now. Nobody can hide in Eden.

Really? Somebody is making a pretty good job of it.

Harvey!

Yeah, all right. Sorry. Tell them we expect to make an arrest in the near future. Usual crap; they know it is and we know it is, but it should satisfy the press for the moment. In any case, it's almost true; my team have eliminated quite a few possibilities, we're narrowing the field. But we have to have more time to correlate the information we've acquired. Nobody ever issued a set schedule for solving murder inquiries.

Two days. I want a positive result which I can announce in two days, Harvey. Someone under arrest or in custody. Understand?

Yes, sir.

The contact ended.

Who was that?rolf asked.

The Governor. He's graciously given me two days to find the murderer.

«Arsehole,» Rolf grunted. He pressed his toe down on the accelerator, and sent the jeep racing over the causeway that traversed the circumfluous lake.

Eden's cyberfactories were installed in giant caverns inside the base of the southern endcap. Apart from the curving walls, they didn't look any different from the industrial halls back in the Delph arcology: row after row of injection moulders, machine tools, and automated assembly bays with waldo arms moving in spider-like jerks. Small robot trolleys trundled silently down the alleys, delivering and collecting components. Flares of red and green laserlight strobed at random, casting looming shadows.

We found Wallace Steinbauer in a glass-walled office on one side of the cavern. The JSKP Cybernetic Manufacturing Division's manager was in his late thirties; someone else I suspected had been gene-adapted. Above-average height, with a trim build, and a handsome, if angular, face that seemed to radiate competence. You just knew he was the right man for the job—any job.

He shook my hand warmly, and hurriedly cleared some carbon-composite cartons from the chairs. His whole office was littered with intricate mechanical components, as though someone had broken open half a dozen turbines and not known how to reassemble them.

Don't get many visitors here, he said in apology.

I let my gaze return to the energetic rows of machinery beyond the glass. This is quite an operation you've got here.

I like to think so. JSKP only posted me here a couple of years ago to troubleshoot. My predecessor couldn't hack it, which the company simply couldn't afford. Cybernetics is the most important division in Eden, it has to function perfectly. I helped get it back on stream.

What do you make here?

The smart answer is everything and anything. But basically we're supposed to provide all the habitat's internal mechanical equipment; we're also licensed by the UN Civil Spaceflight Authority to provide grade-D maintenance and refurbishment on spacecraft components and the industrial stations' life-support equipment; and on top of that lot we furnish the town with all its domestic fundamentals. Anything from your jeep to the water-pumping station to the cutlery on your kitchen table. We've got detailed templates for over a million different items in our computer's memory cores. Anything you need for your home or office, you just punch it in and it'll be fabricated automatically. The system is that sophisticated. In theory there's no human intervention required, although in practice we spend sixty per cent of our time troubleshooting. It's taken eighteen months to refine, but I've finally got us up to self-replication level. Any piece of machinery you see out in that cavern can now be made here. Except for the electronics, which are put together in one of the external industrial stations.

Doesn't Eden import anything?i asked.

Only luxury items. JSKP decided it would be cheaper for us to produce all our own requirements. And that includes all the everyday consumables like fabrics, plastics, and paper. My division also includes recycling plants, which are connected to the habitat's waste tubules. Eden's organs consume all the organic chemicals, but we reclaim the rest.

What about the initial raw materials? Surely you can't make everything from recycled waste. Suppose I needed a dozen new jeeps for my officers?

No problem. Eden digests over two hundred thousand tonnes of asteroid rock each year in its maw; it is still growing, after all.his mind relayed a mental image of the southern endcap, supplied directly from the integral sensitive cells. right at the hub was the maw; a circular crater lined with tall red-raw spines resembling cilia. the largest spines were arrayed round the rim, pointing inwards and rippling in hour-long undulations, giving the impression that some giant sea anemone was clinging to the shell. the arrangement was an organic version of a lobster pot; chunks of ice and rubble, delivered from jupiter's rings by tugs, were trapped inside. they were being broken down into pebble-sized granules by the slow, unrelenting movement of the spines, and ingested through mouth pores in the polyp.

That was when the process became complex. Sandwiched between the endcap's inner and outer layers were titanic organs; first, enzyme filtration glands which distilled and separated minerals and ores into their constituent compounds. Anything dangerously toxic was vented back out into space through porous sections of the shell. Organic chemicals were fed into a second series of organs where they were combined into nutrient fluids and delivered to the mitosis layer to sustain Eden's growth. Inorganic elements were diverted into deep storage silos buried in the polyp behind the cyberfactory caverns, glittery dry powders filling the cavities like metallic grain.

We have huge surpluses of metals and a host of other minerals, wallace steinbauer said. And they're all available in their purest form. We send the metal powder out to a furnace station to get usable ingots and tubing. The minerals we shove through a small chemical-processing plant.

So you're totally self-sufficient now?i said. my admiration for penny maowkavitz had returned with a vengeance after i viewed the maw and its associated organs. that woman had ingenuity in abundance.

I like to think so. Certainly we'll be able to provide Pallas and Ararat with their own cyberfactories. That's our next big project. Right now we're just ticking over with maintenance and spares for our existing systems.

So a simple pistol is no trouble.

That's right.wallace steinbauer rifled through some boxes at the side of his desk, and pulled out the colt with a triumphant grin. No major problem in putting it together, he said. But then I never thought it would be. We could build you some weapons far more powerful than this if you asked.

I took it from him, testing the weight. It struck me as appallingly primitive; looking from the side the grip jutted almost as though it was an afterthought. There was an eagle emblem on the silicon, its wings stretched wide. Interesting point. If you could build any gun you wanted, why choose a weapon like this, why not something more modern?

I'd suggest your murderer chose it precisely because of its simplicity, wallace steinbauer said. The Colt .45 has been around since the late eighteen-hundreds. Don't let its age fool you, it's an effective weapon, especially for close-range work. And from a strictly mechanical point of view it's a very basic piece of machinery, which means it's easy to fabricate, and highly reliable, especially when made out of these materials. I'd say it was an excellent choice.

But why an exact replica?rolf asked. Surely you can come up with something better using the kind of CAD programs we have these days? My kid designs stuff more complicated than this at school, and he's only nine. In fact why bother with a revolver at all? The chimp was only ever going to be able to fire a single shot.

I can give you a one-word answer, wallace steinbauer said. Testing. The Colt is tried and tested, with two hundred years of successful operation behind it. The murderer knew the components worked. If he had designed his own gun he would need to test it to make absolutely sure it was going to fire when the chimp pulled the trigger. And you can hardly test a gun in Eden.

I handed the pistol over to Rolf. Everyone keeps talking about templates, and original components, i said. Where did they come from? I know any reference library memory core would have video images of a Colt. But where did actual templates come from? How did you make this one?

Wallace Steinbauer scratched the back of his head, looking faintly embarrassed. My division has the templates for quite a few weapons. It's the potential, you see. If the police or the Governor ever really needed heavy duty firepower, like if those Boston bastards turn violent, I could provide you with the relevant hardware within a few hours. Those stun guns and lasers you're issued with are only adequate providing you don't come up against anything more powerful.

And the Colt is one of the templates?i said wearily.

Yes, I'm afraid so. I didn't know myself until your department came to me with this request. It looks like someone back on Earth just downloaded an entire History of Armaments almanac for our reference source.

Who else has accessed the Colt's file?

Wallace Steinbauer grimaced apologetically. There's no record of any access prior to my request. Sorry.

Has your computer been compromised?

I thought it was a secure system, but I suppose it must have been. There are only five people in the division including me who have the authority to access the weapons files anyway. So the murderer must have hacked in; if they have the skill for that, erasing access records wouldn't pose any problem.

I used singular-engagement mode to tell Rolf: We'll need alibis for Steinbauer and the other four who can access the weapons file. Also check to see if any of them ever had any contact with Maowkavitz.

Yes, sir.

What about records for machine time?i asked steinbauer. Do you know when the original pistol's components were fabricated?

Again, nothing, he said, cheerlessly. We're going to have to strengthen our whole computer system after this. I didn't realize it was quite so open to abuse. It worries me.

So there won't be any record of the materials being taken out of storage either, i concluded glumly.

No. Hiding a kilogram loss would be absurdly easy. We're used to dealing in ten-tonne units here. Unless it's larger than that we wouldn't even notice it's gone.

Great. OK, Rolf, I want Shannon over here to examine the computer system. See if she can find any signs of tampering.

He pulled a sardonic face. We'll be popular. Do you want her to do that before she tries to crack the rest of Maowkavitz's files?

I winced as I tried to sort out a priority list in my mind. No, Maowkavitz's files must come first. The Cybernetics Division computer is a long shot, but I would like it covered today. Do we have someone else who could run through it?

I could try, if you like. I took software management as my second subject at university.

OK, see what you can come up with. And also run a check through any other memory cores you can think of, see if the Colt's template was on file anywhere else.i gave wallace steinbauer a tight smile. I'd like you to install some stronger safeguards in your computer procedures as soon as possible, please. The idea of people being able to walk in here any time they like and load a template for an artillery piece isn't one I enjoy. I am responsible for Eden's overall security, and this seems like a gaping flaw.

Sure, I'll ask Quantumsoft if they can supply us with a more secure access authority program.

Good. Did you know Penny Maowkavitz?

He inflated his cheeks, and let out an awkward breath. Definitely a question he really did not want to be asked. I knew her. We had to keep the Biotechnology Division informed about the raw material produced by the digestive organs, especially if there were any problems. It was strictly an inter-department contact.

Penny was intractable, i suggested.

You've heard.

Yeah.

We didn't get on terribly well. But there was no point in making an issue out of it. I'm due back to Earth in another four months. And there was her illness . . .

I think you're the first person I've met that doesn't like it here.

I do like Eden, he protested lightly. It's interesting work, challenging. But the Snecma company has offered me a vice-presidential post in the New Kong asteroid. Better pay, more responsibility. I couldn't turn that down.

I left Rolf in Wallace Steinbauer's office to review the Cybernetics Division computer, and drove myself over to Penny Maowkavitz's house. By Eden's standards it was lavish, though nothing like as ostentatious as she could afford. She had built herself a U-shaped bungalow, with the wings embracing an oval swimming pool. It was set in a large garden which was shielded by a hedge of tall fuchsia bushes. I guessed Maowkavitz had designed the bushes herself; the topaz and jade flowers were larger than my fist, looking like origami snowflakes. Quite beautiful.

Davis Caldarola was sitting in a chair at the poolside, slouched down almost horizontally. He was in his fifties, just starting to put on weight. A ruby-red sports shirt and baggy shorts showed me limbs with dark tanned skin and a mass of fine greying hair. A tall glass was standing on the table beside him, rapidly melting ice cubes bobbing about near the bottom. I guessed at vodka and tonic. A second guess that it wasn't his first today. I made a conscious effort not to check with Eden.

He gestured roughly at a nearby chair, and I dragged it over to him.

«Ah, Eden's Chief of Police, himself. I'm honoured. I was wondering when you'd come calling,» he said. The voice was furry, not quite slurred, but close. In his state, I don't suppose he wanted to try holding his thoughts steady enough to use the affinity symbionts. «Your people have been barging round in the house for days.»

«I'm sorry if they're getting in your way. They were told to be as quiet as possible.»

«Ha! You're running a murder investigation. You told them to do whatever they have to, and bugger what—« He broke off and pressed his fists to his forehead. «Shit. I sound like the all-time self-pitying bastard.»

«I think you're entitled to feel whatever the hell you like right now.»

«Oh, very good; very clever. Christ Almighty.» He snatched the glass off the table and glared at it. «Too much of this bloody stuff. But what else is there?»

«I need to know what you can tell me about Penny, but I can come back later.»

He gave a loud snort. «I wouldn't if I were you. I'll be even worse then.» The last of the vodka was downed in a swift gulp. «What can I tell you? She was awkward, argumentative, obstinate, she wouldn't tolerate fools at all, let alone gladly. They all knew that, they all tiptoed around her. ‘Making allowances for her brilliance.' Like bollocks. They were jealous, all of them; her colleagues, her company staff, even that yogi master fruitcake Chong. She wasn't brilliant, she was a fucking genius. They don't call this Eden for nothing, you know, and it's her creation.»

«You're saying people resented her?»

«Some of them, yeah.»

«Anyone in particular?»

«God, I don't know. They're all the same, fawning over her in public, then stabbing her in the back once she's out of earshot. Bastards. None of them are sorry she's gone, not really. The only one who was ever honest about hating her guts was Chong's bimbo. The rest of them . . . they ought to hand out Oscars for the acting at that funeral.»

A servitor chimp came out of the house, carrying another tall glass. It put it on the table beside Davis Caldarola, and picked up the empty one. Davis gave the new glass a guilty look, then squinted over at me. «Have you got any idea who did it?»

«Not a specific suspect, no. But we've eliminated a lot of possibles.»

«You haven't got a fucking clue, have you? Jesus, she's murdered in full view, and you don't have one single idea who did it. What kind of policeman are you?»

I steeled my expression, and said: «A persistent one. I'll find the culprit eventually, but I'll do it a lot quicker with your cooperation.»

He wilted under the rebuke, just as I expected. Davis was a grieving drunk prone to tantrums, not an anti-establishment rebel.

«I want to know about her,» I said more gently. «Did she talk to you about her work?»

«Some. We were a stimulus to each other. I listened to her describe her genetics projects; and I explained my own field to her. She was interesting and interested. That's why our relationship worked so well, we were compatible right across the board.»

«You're an astronomer?»

«Astrophysicist.» He grinned savagely. «Get it right. There's some in my profession who'd be badly offended by that. Think yourself lucky I'm so easygoing.»

«Does the JSKP pay for your work?»

«Some of it, my position is part-funded by the University of Paris. I'm supposed to be studying Jupiter's gravitational collapse. Interesting field.»

«You don't sound very enthusiastic.»

«Oh, there's enough to captivate me. But there's a lot else going on up here, more provoking puzzles. Even after all this time observing Jupiter at close range, and dropping robot probes into the atmosphere, there's very little we know about it, certainly what goes on within the deeper levels, below the altitude which the probes can reach. Our solid-state sensor drones implode long before they reach the semisolid layers. All we've got on the interior is pure speculation, we don't understand what happens to matter at those sort of compression factors, not for sure. And Christ alone knows what's actually taking place at the core. There's a hundred theories.»

«And Penny was interested?»

He picked the glass of vodka up, swirled the ice, then put it down without drinking any. «Yeah. Academically, anyway. She could follow the arguments.»

«What did she tell you about her work?»

«Whatever she wanted. What bugged her, what was going well, new ideas. Christ, she would come up with some bizarre concepts at times. Balloon fish that could live in Jupiter's atmosphere, mythological creatures, webs of organic conductors which could fly in the Earth's ionosphere.»

«Anything really radical?»

«What? Those not enough for you? Don't you want to see dragons perching on the mountaintops again?»

«I meant something which could upset national economies, or put companies out of business.»

«No, nothing like that. Penny wasn't an anarchist. Besides, ninety per cent of her time was still tied up with developing the next generation of habitats. She was determined to do as much as she could before . . .» He trailed off helplessly.

«So, no secret projects, no fundamental breakthrough to crown her achievements?»

«No. The habitats were enough for her.»

«Did she ever mention anyone she was having trouble with?»

He gave the glass another covetous look. «No individuals. She was narked with some of the Boston crowd—« He stopped. Flinched. «You know about them?»

«Oh, yes. I know all about you.»

He grunted dismissively. «Big deal.»

«I take it the Boston argument was over the timing of independence?»

«Christ, some secret society we are. Yes. OK. All right, everyone knows it. Penny wanted the declaration as soon as the cloudscoop was operational. She was trying to talk people round, those that supported Parkinson. Which wasn't a good idea, she's not the diplomatic type. I was doing what I could, trying to help. She deserved to see independence.» His eyes narrowed on my uniform's UN insignia. «The old order overthrown.»

«What about you and her, did you ever argue?»

«You shit. You think I'd do that? I'd kill Penny? You fucked-up Gestapo bastard.» He hurled the glass of vodka towards me in an unsteady lurch. I didn't even have to duck, the aim was so wild. It splashed into the pool and sank, leaving just the ice cubes floating about.

I wanted to tell him. That it was just procedure. That he shouldn't take it personally. And that, no, I didn't think he killed her. But his whole face was contorted into abject misery, on the verge of tears.

Instead, I stood up and mumbled something vaguely apologetic. I don't suppose he even heard. Another servitor chimp carrying a fresh glass was already heading over to him when I slid open a patio door and stepped into Penny Maowkavitz's study.

Nice going, boss, shannon said. she was sitting in a luxurious scarlet swivel chair in front of a computer console, registering moderate exasperation.

You know I had to ask.

Yes. And I could have told you what reaction you would get.

Yeah.

But then that's what Davis would do even if he was guilty.

I looked at her in surprise. Do you think he's guilty?

No.

You're a big help.

How did it go at the Cybernetics Division?

Not good. Their computer security is a shambles. How are you making out with this one?i gazed at maowkavitz's computer; it was a powerful hypercube marque, with enough capacity to perform genesplice simulations. shannon had removed three panels from the side of the console, exposing the neat stack of slim processor blocks inside. a rat's nest of fibre-optic ribbons wormed their way through the databuses, plugging the system into several customized electronic modules lying on the carpet.

Shannon shoved some of her loose copper hair back from her forehead, and pointed to her own laptop terminal balanced on the edge of the console. Tough going, but I think I'm making progress.

I frowned round the study; it was almost depersonalized. A white-wall cube with a few framed holograph stills of various animals and plants I suspected where Maowkavitz's own gene-adaptions. How come Eden doesn't know the codes?

It can't see in. The whole room is made of composite, even the floor, and the patio door is silvered.

Funny. Not allowing her own creation to see what she was up to.

You think that's significant?

Insufficient data, which you're going to rectify for me. Today, remember?

If Boston includes police unionization and improved working conditions on its manifesto, they'll get my vote.

After that interview with Caldarola, which I can only describe as badly bungled, I drove back to the police station with the first chill of depression souring my thoughts. Or maybe it was plain honest guilt. I should have gone easier on Davis Caldarola; I knew full well he wasn't in any state to answer difficult personal questions. Then again, Shannon was quite right saying what she had: if he was guilty, that's exactly how he would behave.
