«And biotechnology habitats are also autonomous,» I observed. «You don't need spare parts for them either.»
   «True. But it's not quite that simple. For all its size and cost and technology, the JSKP operation here is still very much a pioneering venture; roughly equivalent to the aircraft industry between the last century's two World Wars. We're at the propeller-driven monoplane stage.»
   «That's hard to credit.»
   «You've talked to Pieter Zernov, I believe. He's full of dreams of what the habitats can eventually evolve into. We need money for that, money and time. Admittedly not much in comparison to the cost of a cloudscoop; but nor is it a trivial sum. Then there's Callisto. At this moment I've got a team there surveying the equator for a suitable mass driver site. JSKP is planning to start construction in 2094, and use it to fire tanks of He3 at Earth's L3 point. There will be a whole string of tanks stretching right across the solar system. It'll take three years for them to arrive at L3, but once they start, delivery will be continuous. A mass driver will eliminate the need for ships like the Ithilien to make powered runs every month.»
   «So what are you worried about? That Earth won't supply the parts for a mass driver? They'll be acting against their own interest. Besides, you'll always find one company willing to oblige.»
   «It's not the availability of technology. It's the cost. The next decade is going to see JSKP investment in Jupiter triple if not quadruple. And it's only after that, when there are several cloudscoops operational, and the mass driver is flinging He3 at Earth on a regular basis, when you'll start to see the cash flow reversing. Once we've established a He3 delivery operation sophisticated enough to function with minimum maintenance and minimum intervention, the real profits are going to start rolling in. And that's when we can start thinking about buying out the existing shareholders.»
   «I see what you mean. If you try and buy them out now, you won't have the money for expansion you need.»
   He nodded, pleased I was seeing his viewpoint. «That's right. All this talk of independence is really most impulsive and premature. It can happen, it should happen, but only when the moment is right to assure success.»
   Company line, that's what it sounded like to me. Which left me thinking: would a JSKP vice-president really be an unswervingly committed member of a rebellion against the board? Whatever the outcome, independence or otherwise, Bob Parkinson would keep the same job, probably for the same pay. Christ, but he'd manoeuvred himself into a superb position to play both ends against the middle. Just how shrewd was he?
   «From what you've just told me, Boston actually benefited from Penny Maowkavitz's death.»
   «That's way out of line, Chief, and you know it.»
   «Yeah. Sorry. Thinking out loud; it's a bad habit. But I have to run through the process of elimination.»
   «Well, I'd say you can eliminate any Boston members. Pieter told you what kind of ideals drive us. If it had come to a vote, Penny would have abided by the majority decision, as would I.»
   «You mean you haven't decided yet?»
   «There is a line, Chief Parfitt, and you are not on our side of it. I've put myself in a most dangerous position confiding in you. One word to the board from you, and my role out here is finished, along with my career and my pension and my future. But I talked to you anyway, honestly and openly, because I can see you genuinely want to find Penny's murderer, and I believe you're capable of doing so. But informing you of anything more than our general intentions, things which you could pick up in any bar in the habitat, that's out of the question. You see, you've been making some very ingratiating sounds towards us, words we like to hear, words we're flattered to hear, especially from your lips. But we don't know if they're real, or if they're just an excellent interview technique. So why don't you tell me; will the Eden police try to prevent Boston from achieving independence?»
   I looked into his hooded eyes, searching for the depth which must surely come from being augmented by other minds. There was a great deal of resolution, but nothing much else. Bob Parkinson was a man alone.
   So I had to ask myself, did he really think the board didn't know of his membership? Or if they did, and he was their provocateur, why wouldn't he tell me?
   «It's like this,» I said. «I would never fight a battle, unless I knew I'd already won.»
 
   • • •
 
   My third day started with a dream. I was completely naked, standing on Jupiter's delicate ring. Clouds swirled eternal below me, perfectly textured mountains of frozen crystals glittering in every shade of red, from deep magenta to a near-dazzling scarlet. Close enough that I could reach out and touch them, fingertips stirring the interlocking whorls, bathing my skin in a sensation of powder-fine snow. It tingled. The planet was crooning plaintively, a bass whalesong emerging from depths beyond perception. I watched, entranced, as its energy shroud was revealed to me, the magnetosphere and particle wind, embracing it like the milk-white folds of an embryo membrane. They palpitated slowly, long fronds streaming out behind the umbra.
   Then the palpitations began to grow, becoming more frenzied. Long tears opened up, spilling out a precious golden haze. A ripping sound grew into thunder, and the ring quaked below my feet.
   I knifed up on the bed. Clean sober awake. Heart racing, sweaty. And for some reason, expectant. I glanced round the darkened room. Jocelyn was stirring fitfully. But someone was watching me.
   A faint mirage of a man sitting up in bed, staring round wildly.
   «What is this?»
   Please relax, Chief Parfitt, there is nothing to worry about. You are experiencing a mild bout of disorientation as your symbiont implants achieve synchronization with my neural strata. It is a common phenomenon.
   It wasn't a spoken voice, the room was completely silent. The hairs along my spine prickled sharply as though someone was running an electric charge over my skin. It was the memory of a voice, but not my memory. And it was happening in real-time.
   «Who?» I asked. But my throat just sort of gagged.
   I am Eden.
   «Oh, Christ.» I flopped back on the mattress, every muscle knotted solid. «Do you know what I'm thinking?» The first thing which leapt into my mind was that last row with Jocelyn. I felt my ears burning.
   There is some random overspill from your mind, just as you perceived some of my autonomic thought routines. It is a situation similar to a slightly mistuned radio receiver. I apologize for any upset you are experiencing. The effect will swiftly fade as you grow accustomed to affinity.
   Jupiter again; a bright vision of the kind which might have been granted to a prehistory prophet. Jupiter floated passively below me. And space was awash with pinpricks of microwaves, like emerald stars. Behind each one was the solid bulk of a spacecraft or industrial station.
   «That's what you see?»
   I register all the energy which falls upon my shell, yes.
   I risked taking a breath, the first for what seemed like hours. «The inside. I want to see the inside. All of it.»
   Very well. I suggest you close your eyes, it makes perception easier when your brain doesn't have two sets of images to interpret.
   And abruptly the habitat parkland materialized around me. Dawn was coming, washing the rumpled green landscape with cold pink-gold radiance. I was seeing all of it, all at once. Feeling it stir as the light awoke the insects and birds, its rhythm quickening. I knew the axial light-tube, a slim cylindrical mesh of organic conductors, their magnetic field containing the fluorescent plasma. I sensed the energy surging into it, flowing directly from the induction pick-off cables spread wide outside. Water surged along the gentle valleys, a cool pleasing trickle across my skin. And always in the background was the mind-murmur of people waking, querying the habitat personality with thousands of mundane requests and simple greetings. Warmth. Unity. Satisfaction. They were organic to the visualization.
   «My God.» I blinked in delighted confusion at the thin planes of light stealing round the sides of the curtains beyond the end of the bed. And Jocelyn was staring at me suspiciously.
   «It's started, hasn't it?»
   I hadn't heard her sound so wretched since the last miscarriage. Guilt rose from a core of darkness at the centre of my mind, staining every thought. How would I react if she ever went ahead and did something I considered the antithesis of all I believed in?
   «Yes.»
   She nodded mutely. There wasn't any anger in her. She was lost, totally rejected.
   «Please, Jocelyn. It's really just a sophisticated form of virtual reality. I'm not letting anyone tinker with my genes.»
   «Why do you do that? Why do you treat me as though my opinions don't matter, or they're bound to be wrong? Why must you talk as if I'm a child who will understand and thank you once you've explained in the simplest possible terms? I lost our children, not my mind. I gave up my life for you, Harvey.»
   Right then, if I could have pulled the symbionts out, I think I would have done it. I really do. Christ, how do I land myself into these situations?
   «All right.» I reached out tentatively, and put my hand on her shoulder. She didn't flinch away, which was something, I suppose. «I'm sorry I did that, it was stupid. And if you've been hurt by coming here, by me having the symbiont implant, then I want you to know it was never deliberate. Christ, I don't know, Jocelyn; my life is so straightforward, all mapped out by the personnel computer at Delph's headquarters. I just do what they tell me, it's all I can do. Maybe I don't take the time to think like I should.»
   «Your career is straightforward,» she said softly. «Not your life. We're your life, Harvey, me and the twins.»
   «Yes.»
   A faint resigned smile registered on her lips. «They like it here.»
   «I really didn't know the other kids in the arcology were tough on them.»
   «Me neither.»
   «Look, Jocelyn . . . I saw Father Cooke yesterday.»
   «What about him?»
   «He's a smart old boy; that's what. Perhaps I should go and see him again. I'm not too proud to ask for help.»
   «You'd do that?» she asked, uncertainty gave her voice a waver.
   «Yes, I'd do that.»
   «I don't want us to be like this, Harvey. It was good before.»
   «Yeah. Which means it can be again, I suppose. I'll go and see Cooke, then, find out what he's got to say about us. Uh, I'm not sure if I can do it today.»
   «I know. The Maowkavitz case.»
   «Her and Boston. Everything always comes at once, doesn't it?»
   «And at the worst time. But that's something I knew even before I married you.»
 
   • • •
 
   It was Eden which guided me to Wing-Tsit Chong's residence, that echo of a voice whispering directions into my brain. I drove myself there right after breakfast, it was too early for Nyberg to be on duty. I didn't feel like her company anyway. But I had a rising sense of satisfaction as I steered the jeep along a track through the parkland; at least Jocelyn and I were talking again.
   The old geneticist lived some way out of the town itself, a privilege not many people were granted. The Agronomy and Domestic Maintenance divisions wanted to keep all the buildings in one neat and tidy strip. If everyone was allowed a rustic cottage in the woodlands the whole place would have been crisscrossed with roads and power cables and utility pipes. But for Wing-Tsit Chong they made an exception. I expect even administration types held him in the same kind of reverence that I did. Whether you approved of it or not, affinity was such a radical discovery.
   His residence was a simple bungalow with a high, steeply curved blue slate roof which overhung the walls to form an all-round veranda. Very Eastern in appearance, to my untutored eye it resembled a single-storey pagoda. There was none of the metal and composite panelling which was used in most of the habitat's buildings, this was made from stone and wood. It had been sited right on the edge of a small lake, with the overlooking veranda standing on stilts above the vitreous water. Black swans glided imperiously across the surface, keeping just outside the thick band of large pink and white water lilies which skirted the entire lake. The whole area seemed to siphon away every sound.
   Wing-Tsit Chong and Hoi Yin were waiting for me on the wooden lakeside veranda. She was dressed in a simple sleeveless white-cotton robe, standing behind her mentor, as stern and uncompromising as ever. Wing-Tsit Chong however smiled welcomingly as I came up the short flight of steps from the lawn. He was sitting in his ancient wheelchair, dressed in a navy-blue silk jacket, with a tartan rug wrapped round his legs. His face had the porcelain delicacy of the very old; my file said he was in his early nineties. Almost all of his hair had gone, leaving a fringe of silver strands at the back of his head, long enough to come down over his collar.
   It is most gratifying to meet you, Chief Parfitt. The habitat rumour band has talked of no one else for days.he chuckled softly, small green eyes alight with a child's mischief.
   «It was very good of you to agree to tutor me. As you can see, I still haven't got a clue about affinity.»
   This we shall change together. Come, sit here. Hoi Yin, some tea for our guest.
   She flashed me a warning glance as she went inside. I sat in a wicker chair opposite Wing-Tsit Chong. Dulled copper wind chimes hanging along the edge of the eaves tinkled quietly. I really could imagine myself attending some spiritual guru back in Tibet.
   A good girl. But somewhat overprotective of me. I ought to be grateful to have anyone so attentive at this time in my life.
   «She thinks I'm wasting your time.»
   The chance to offer guidance towards understanding is not one I can lightly refuse. Even an understanding as simple as this one. All life is a steady progression towards truth and purity. Some achieve great steps in their quest to achieving spiritual clarity. Others are doomed to remain less fortunate.
   «That's Buddhist philosophy, isn't it?»
   Indeed. I was raised in that fashion. However, I diverged from the training of Patimokkha traditions many years ago. But then arrogance is my vanity, I acknowledge this with great sadness. But still I persist. Now then; the task in hand. I wish you to talk to me without using your voice. Subvocalization is the talent you must master. The focus, Chief Parfitt, that is the key to affinity, the focusing of your mind. Now, a simple greeting: Good morning. Look at me. Nothing else, only me. Form the words, and deliver.
 
   • • •
 
   I sat on that veranda for two hours. For all his smiling frailty, Wing-Tsit Chong was unrelenting in pursuing my education. The whole session put me in mind of those adolescent martial arts series on the entertainment cables, stumbling pupil and wise old master.
   I did indeed learn how to focus my thoughts. How to flick a mental switch that allowed me to use affinity when I wanted rather than that initial erratic perception which I'd experienced. How to recognize individual mental signatures and use singular engagement. I eavesdropped on the general bands which filled the habitat's ether, the gossips who discussed every subject under the sun; not so dissimilar from the net bulletins on Earth. Communion with Eden was the most fascinating, having its entire mental and sensory facilities available at a whim—using them time and again until the commands became instinctive. Instructing servitors. Sending my own optical images, receiving other people's.
   Only then did I realize how restricted I had been until that moment. Earth was the kingdom of the blind, and Eden the one-eyed man.
 
   • • •
 
   This is a priceless gift, i told wing-tsit chong. I thank you.
   I am pleased you think it useful.
   Whatever gave you the original idea for affinity?
   A fusion of disciplines. My spiritual precepts told me that all life is in harmony. As a scientist I was fascinated by the concept of nonlocal interaction, a mathematical explanation for atomic entanglement. Quantum theory permits us to consider a particle as a wave, so the wave function of one particle may overlap another even though they are at distance. An effect once described as atomic telepathy. The original neural symbionts I developed allowed me to exploit this loophole and produce instantaneous communication. Identical cloned cells are able to sense the energy state in their twin. They are in harmony.
   But if affinity confirmed your Buddhist principles, why have you rejected it?i asked.
   I have not rejected the Buddha's basic tenets; rather I seek a different road to dhamma, or the law of the mind, which is the goal of the Buddhist path.
   How?
   I consider the nature of thought itself to be spiritual. Human thought is our mystery, it is our soul. All states of existence are contained within our own minds. Buddhists believe that thoughts should be cleansed and simplified to bring about progress along the path. For myself, I consider every thought to be sacred, they should all be treasured and revered, no matter what they are; only the wealth of experience can bring about enrichment of the soul. You cannot achieve this by meditation alone. By purifying your mind, you become nothing more than a machine for thinking, a biological computer. We are meant for more than that.
   Hoi Yin was rocking her head in agreement with everything he said. She had sat in on the whole affinity training session, helping Wing-Tsit Chong to drill me in the essentials. Her attitude towards me hadn't changed; and affinity showed me her thoughts were as hard and cold as her expression. But she remained quite devoted to the old man. I was becoming very curious about the underlying nature of their relationship. At first I'd thought she might be a relative, a granddaughter or a niece, but now I could see it wasn't that sort of attachment. She called herself his student. I'd say it was more like his acolyte.
   Is this what you believe, as well?i asked her.
   Alert tawny eyes regarded me for a full second, searching for treachery in the question. Of course. I have learnt to order my thoughts rationally. To accept what I am, and be thankful for it. I savour the essence of life.
   So why do you never smile? I asked myself.
   Hoi Yin has accomplished much in the time she has been with me, wing-tsit chong said. But it is Eden itself which is my greatest pupil, and my greatest challenge.
   I couldn't stop the amazed grin from spreading over my face. You're teaching Eden to be a Buddhist?the image that brought up was ridiculous; i hoped to hell that i genuinely had learnt how to internalize my flights of fantasy.
   No. I simply teach Eden to think. That is why I am here. This technophile conquest of Jupiter holds no interest for me, other than a purely academic admiration for the accomplishments of the JSKP's engineering teams. It is the habitat's intellectual nurturing which I consider important enough to devote my last days to. My final work.
   I developed affinity symbionts for the Soyana corporation back in 2058, and they made a great deal of money from selling bonded servitors before the worsening social and religious situation on Earth virtually closed down the market. It was on my insistence that they joined the JSKP consortium. I pointed out to the Soyana board that with a single modification to the proposed design of the habitats they could develop a whole new market here in Jupiter orbit where the population was uniformly educated, and largely immune to popular prejudice. I could see how the most effective utilization of servitors could be brought about, and advocated incorporating what is now termed the neural strata into Eden. Prior to this, it was envisaged the habitat would have only a small cluster of neural cells, possessing a limited sentience to regulate its functions. Penny Maowkavitz and I collaborated to design the cells and structure of the neural strata. And afterwards, while she devoted her energies to refining the design of new habitats, I assisted with the birth of Eden's consciousness.
   You mean it wasn't sentient to start with?i asked. How could something this smart not be self-aware?
   Wing-Tsit Chong smiled fondly out over the lake. The consciousness which is every human's birthright is a gift often overlooked. It is brought about over many years by responding to stimuli, by parental devotion in imparting language and example. Now consider a habitat seed; already its neural kernel is orders of magnitude larger than a human brain. Hoi Yin has explained to you how the neural strata is a homogeneous presence operating innumerable thought routines simultaneously. Well, those principal thought routines were all designed by me, and entered into the seed as growth was initiated. I have remained here almost ever since, guiding Eden through the inevitable confusion which awakening engenders in any living entity, and assisting it in refining those routines as required. There was, after all, so much I could not possibly foresee.
   Penny Maowkavitz was the creator of my physical structure,eden said, Wing-Tsit Chong is the father of my mind. I love them both.
   Hoi Yin was watching me closely, waiting for my reaction.
   You can love?i asked.
   I believe so.
   Any entity with a soul can love, wing-tsit chong said. It is only the fault of our flawed society that not all are given the chance to love. For only by showing love can you receive love in return. This is what I consider to be the most fundamental act of dana, the Buddhist practice of giving. In its purest state, dana is a sacrifice of self which will allow you complete understanding of the needs of others. And in doing so you transform yourself. A supreme state of Nibbana achievable only with unselfish love. Sadly so few are capable of such munificence.
   I expect you're right.i was getting out into waters way beyond my depth. philosophy doesn't figure very heavily on the hendon police college's training courses. i wondered what father cooke would have to say on the subject of eden having a soul.
   You worked with Penny Maowkavitz?i asked.
   For many years,wing-tsit chong said. As a geneticist she was peerless. So many fine ideas. So much energy and single-minded determination. Given the diversity of our respective cultural backgrounds our temperaments were not conjunctive, but even so we achieved much together. Eden alone is testament to that. I await with some eagerness to see what it is that will bloom from her grave. To experience eagerness at my age is remarkable. Only she could bring about such a thing.
   Did she confide in you at all?
   Alas no. Our union was conducted on a professional level. I was filled with sorrow at her radiation accident, and I grieve her death. To suffer so is a tragedy. But both of these incidents can only be understood in the greater nature of Kamma; our past actions create our present life.
   You mean she deserved it?i asked, surprised.
   You misunderstand; there is no cruelty involved with the law of Kamma, which is given as: knowledge of the ownership of deeds. The nearest Western interpretation of this would be controlling your own destiny. Only you are responsible for your own future. And the future is determined by the past.
   Reap as ye shall sow, i said.
   Again this is too literal, it demonstrates a Western inclination towards belief in preordained fate. You are rooted in the physical world. The determinative actions to which Kamma refer are acts of will.
   Right.i could see myself developing another headache if this went on much longer. now that's fate, action and reaction. So you don't know of anyone who would wish to harm her?
   No, I regret I can shed no light on the perpetrator for you.
   What about Boston?i asked. You're not listed as a member in the files I have been given. Do you support its aims?
   You asked to come here to learn about affinity, hoi yin interjected sharply. You outstay your welcome, Chief Parfitt.
   Patience.wing-tsit chong held up a hand, still smiling softly. Chief Parfitt has a job to do. We will assist in any way we can, and in doing so honour the memory of Penny Maowkavitz.
   Hoi Yin slouched down further in her chair. For someone who claimed to embrace rational thought, she could be amazingly petulant.
   I have taken no active role in the Boston group's activities, wing-tsit chong said. As you see, Chief Parfitt, I am no longer as robust as I once was. I chose to devote my remaining time to Eden, Pallas, and now Ararat. They still need nurturing; intellectually they remain children. I have been asked to endorse the Boston group, of course, several times. My name, they feel, will add weight to their campaign. I declined because I do not wish the indignity of becoming a meaningless symbol. Boston conducts its campaigns in what I see as very much a materialistic arena, who owns what, who has the right to issue orders. I do not condemn economics nor their ideological pursuit of national self-determination; but these causes must be seen in the context of the greater reality. The people of Eden already build and control the industrial facilities in Jupiter orbit. What is, is. Everything else is book-keeping, the chosen field of contest for those who lead the movement. JSKP and Boston are two armies of accountants, waging war in boardrooms.
   A storm in a teacup, i said.
   Wing-Tsit Chong gave a thin laugh. You are an interesting man, Chief Parfitt. You see more than you admit. If there is any other question arising from your investigation, please do not hesitate to contact me. You have the skill to do this, now.
   I do. And again I thank you for it.
   Hoi Yin and I stood up together. She fussed round Wing-Tsit Chong for a moment, tucking his blanket under his knees, straightening his silk jacket. I looked out over the lake. There was a small waterfall at the far end, its spray acting as a cage for rippling rainbows. The swans had all vanished. When I turned back, Hoi Yin was already pushing the wheelchair through a door into the house. I just couldn't work that girl out.
 
   • • •
 
   I drove the jeep halfway back towards the town, then pulled off the track and stopped. A subliminal query, and I knew that no one else was using the track, nor was there anyone walking through the surrounding parkland. I shook my head in bemusement when I realized what I'd done.
   I closed my eyes and settled back comfortably on the seat. This was something I'd known I would have to do right from the moment I got the call saying Maowkavitz had been murdered.
   Eden?
   Yes, Chief Parfitt.
   Show me your memory of Penny Maowkavitz's death.
   It was a composite of memories, taken from the various sensitive cells around Lincoln lake—mock-rock outcrops along the shore, small polyp-sided gullies, affinity-bonded birds and field mice, even smooth stones apparently jutting from the soil at random were polyp. Eden blended the viewpoints together, making it seem as though I was an invisible ghost floating beside Penny Maowkavitz as she took her morning walk.
   Just by looking at her I knew that had we ever met we would never have got on. There was no sympathy in the way her face was set; she had a core of anger that burned far darker than Hoi Yin's inner demon. The way she walked, legs striding on purposefully through the thick grass, belayed any impression of a casual stroll. She didn't drink down the view on her inspections; the wild flowers and the tangled trees had no intrinsic aesthetic value, they were simply aspects of design, she was hunting for faults and flaws.
   She came to the side of the lake, and made her way along the fine shingle around the edge. Beads of sweat were appearing on her face, glinting softly in the silver glimmer of the axial light-tube. I could smell their muskiness in the air. She undid the front of her long jacket, a spasm of irritation crossing her face as her hand touched the vector regulators strapped to her belly.
   Ten metres away the servitor chimp was walking across the grass, heading at a slight angle towards the lake. It had a dark utility bag to carry its gardening implements, the fabric stained and fraying, bulging with odd shapes. Penny Maowkavitz never paid it the slightest attention.
   I focused on her face. The wig wasn't on quite straight. Her lips were twitching, the way they do when people are lost in thought. What I'm sure was a frown had just started to crease her forehead when the chimp put its hand in the bag. Whatever problem Penny Maowkavitz was working on, its solution was eluding her. The chimp pulled out the pistol, its arm swinging round to point at her. Surprise flamed in her eyes, and her mouth started to open. Below her feet, Eden's general observation routines registered the object in the chimp's hand. Pattern recognition procedures were enacted immediately. Penny Maowkavitz's first flare of alarm impinged upon the neural strata. It ended abruptly as the chimp pulled the trigger.
   Blood and brain erupted as her skull blew open.
   The chimp froze as Eden's frantic command overrode every nerve impulse. Although even the habitat couldn't stop its teeth from chittering in fright. Primitive emotions whirled through its simple brain: terror, regret, panic, the last remnants of its animal origin fighting for recognition.
   If I had a more developed instinct I would have seized control of the servitor chimp much sooner, eden said sorrowfully. As it was, I took too long to identify the pistol for what it was. Penny Maowkavitz might have been alive today if I had not taken so long.
   Self-recrimination is unhealthy, i told it. christ, nursemaid to a habitat. but its thoughts had a timbre that made me think of a knowing child. i could hardly be angry, or even sarcastic. You have learnt from the incident. That's as much as any intelligent creature can hope for.
   You sound like Wing-Tsit Chong.
   Then I must be right.
   Instinct is a hard concept for me. So much of what I think is logical, precise.
   Finding out the world is neither kind nor well ordered is all part of growing up. Painful but necessary.
   I wish it was different.
   Believe me, we all do. How come you can't remember any further back? This happened more than thirty hours ago.
   I have two memory levels. The first is short term, a thirty-hour storage for every impression gathered by my sensitive cells. If something untoward occurs which I did not initially realize the importance of, such as who placed the bag with the pistol for the chimp to collect, then it can be recovered providing I am informed before the thirty hours are up. Other than that, memory is pointless. Why would I wish to memorize years of parkland in which no activity is occurring? If every sensitive cell impression were to be placed immediately into long-term memory, my total capacity would quickly be filled. So these observation memories dissipate quite naturally. Long-term memory is a conscious act, whereby I transfer over events from the short term for permanent record.
   That makes sense, I suppose. That short-term facility is like a security camera recording they use in the public areas back in the arcologies.i paused, recalling what i had reviewed. I want the memory again, but just the end section this time. After the chimp shoots her.
   The gunshot, shockingly loud to the chimp's unsuspecting ears. Eden's affinity orders slamming into its brain. A moment when the ether reverberated with their thoughts. Then the chimp's mind was engulfed by the habitat's glacial control. I could actually feel every muscle in in its body locked solid; looking through its eyes, seeing the grisly body toppling over.
   Again, please.
   But I already knew. In the instant between firing the shot, and being captured, a single thought-strand of regret had slithered through the chimp's mind. Where the hell had that come from?
 
   • • •
 
   Rolf was rising from his chair to greet me as soon as I walked into the incident room. «We had a positive result from Wallace Steinbauer over at the cyberfactory,» he said. «They've managed to put together a Colt .45 pistol. I said we'll come over and see for ourselves.»
   Excellent.
   The corner of his mouth lifted in sardonic acknowledgement. Welcome aboard, Chief.
   Thanks. By the way, I've been reviewing Eden's memory of the murder. Has anyone noticed the chimp's emotional outburst after it shot Maowkavitz?
   That earned me some blankly puzzled looks from around the room.
   No, sir, rolf said cautiously.
   Another point to the good guys. Then I suggest you all review it again. The chimp experiences quite a degree of regret immediately after pulling the trigger. I'd like some ideas why that should be, please. How are we doing with the other lines of enquiry?
   Still nothing in Maowkavitz's immediate past. No arguments, no disputes. And we've just about finished interviewing all the people she came into contact with. Oh, and the Governor is in the clear. We've more or less confirmed he didn't leave the pistol for the chimp. His schedule's been pretty hectic for weeks, he hasn't had the time to put together the pistol or wander out into the parkland.
   I ignored the jeer from the back of the room. Through Eden's sensitive cells in the polyp floor I knew it was Quinna. I wasn't even aware I'd enquired. This was going to take some getting used to. You do surprise me. Well, that snippet isn't to be considered confidential.
   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 Fasholé Nocord sitting at his desk.
   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?
