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?
