I felt a vague pang of guilt as I thought of the AI thrashing like a man in an acid vat as its systems dissolved around it, consciousness shrivelling down a tunnel of closing perspectives into nothing. The feeling passed rapidly. We’d chosen Jack It Up for a variety of reasons: it was in a roofed-over area that meant there would be no satellite coverage to dispute the lies we’d planted in the mall surveillance system, it operated in a criminal environment so that no one would have a problem believing an illicit virus had somehow got loose inside it, but most of all it ran a series of software options so distasteful that it was unlikely the police would ever bother to investigate the wreckage of the murdered machine more than cursorily. Under its heading on Ortega’s list, there were at least a dozen copycat sex crimes which the Organic Damage department had traced to software packages available from Jack It Up. I could imagine the curl of Ortega’s lip as she read the software listings, the studied indifference with which she would handle the case.

I missed Ortega.

“What about Kadmin?”

“It’s hard to know, but I’m betting whoever infected Jack It Up in the first place probably hired Kadmin to silence me and make sure the whole thing stayed covered up. After all, without me stirring things up, how long would it have been before anyone realised Jack had been iced? Can’t see any of its potential clients calling the police when they got refused entry, can you?”

Bancroft gave me a hard look, but I knew from his next words that the battle was almost over. The balance of belief was tipping towards me. Bancroft was going to buy the package. “You’re saying the virus was introduced deliberately. That someone murdered this machine?”

I shrugged. “It seems likely. Jack It Up operated on the margins of local law. A lot of its software appears to have been impounded by the Felony Transmission department at one time or another, which suggests that it had regular dealings with the criminal world in one form or another. It is possible that it made some enemies. On Harlan’s World the yakuza have been known to perform viral execution on machines judged to have betrayed them. I don’t know if that happens here, or who’d have the stack muscle to do it. But I do know that whoever hired Kadmin used an AI to pull him out of police storage. You can verify that with Fell Street, if you like.”

Bancroft was silent. I watched him for a moment, seeing the belief sink in. Watching the process as he convinced himself. I could almost see what he was seeing. Himself, hunched over in an autocab as the sordid guilt over what he had been doing at Jack It Up merged sickeningly with the horror of the contamination warnings sirening in his head. Infected! Himself, Laurens Bancroft, stumbling through the dark towards the lights of Suntouch House and the only surgery that could save him. Why had he left the cab so far from home? Why had he not wakened anybody for help? These were questions I no longer needed to answer for him. Bancroft believed. His guilt and self-disgust made him believe, and he would find his own answers to reinforce the horrific images in his head.

And by the time Transmission Felony cut a safe path through to Jack It Up’s core processors, Rawling 4851 would have eaten out every scrap of coherent intellect the machine ever had. There would be nothing left to dispute the carefully constructed lie I’d told for Kawahara.

I got up and went back to the balcony, wondering if I should allow myself a cigarette. It had been tough to lock down the need the last couple of days. Watching Irene Elliott at work had been nerve-racking. I forced my hand to relinquish the packet in my breast pocket, and gazed down at Miriam Bancroft, who by now was well on the way to completing her glider. When she looked up, I glanced away along the balcony rail and saw Bancroft’s telescope, still pointed seaward at the same shallow angle. Idle curiosity made me lean across and look at the figures for angle of elevation. The finger marks in the dust were still there.

Dust?

Bancroft’s unconsciously arrogant words came back to me. It was an enthusiasm I had. Back when the stars were still something to stare at. You wouldn’t remember how that felt. Last time I looked through that lens was nearly two centuries ago.

I stared at the finger marks, mesmerised by my own thoughts. Someone had been looking through this lens a lot more recently than two hundred years ago, but they hadn’t kept at it very long. From the minimal displacement of dust it looked as if the programming keys had only been used once. On a sudden impulse, I moved up to the telescope and followed the line of its barrel out over the sea to where visibility blurred in the haze. That far out the angle of elevation would give you a view of empty air a couple of kilometres up. I bent to the eye-piece as if in a dream. A grey speck showed up in the centre of my field of vision, blurring in and out of focus as my eyes struggled with the surrounding expanses of blue. Lifting my head and checking the control pad again, I found a max amp key and thumbed it impatiently. When I looked again, the grey speck had sprung into hard focus, filling most of the lens. I breathed out slowly, feeling as if I’d had the cigarette after all.

The airship hung like a bottleback, gorged after feeding frenzy. It must have been several hundred metres long, with swellings along the lower half of the hull and protruding sections that looked like landing pads. I knew what I was looking at even before Ryker’s neurachem reeled in the last increments of magnification I needed to make out the sun-burnished lettering on the side that spelled it out; Head in the Clouds.

I stepped back from the telescope, breathing deeply, and as my eyes slid back to normal focus I saw Miriam Bancroft again. She was standing amidst the parts of her glider, staring up at me. I almost flinched as our eyes met. Dropping a hand to the telescope programme pad, I did what Bancroft should have done before he blew his own head off. I hit memory-wipe, and the digits that had held the airship available for viewing for the last seven weeks blinked out.

I had felt like many kinds of fool in my life, but never quite as completely as I did at that moment. A first-order clue had been waiting there in the lens for anyone to come along and pick it up. Missed by the police in their haste, disinterest and lack of close knowledge, missed by Bancroft because the telescope was so much a part of his world view it was too close to give a second glance to, but I had no such excuses. I had stood here a week ago and seen the two mismatched pieces of reality clash against each other. Bancroft claiming not to have used the telescope in centuries almost at the same moment that I saw the evidence of recent use in the disturbed dust. And Miriam Bancroft had hammered it home less than an hour later when she said, While Laurens was staring at the stars, some of us kept our eyes on the ground. I’d thought of the telescope then, my mind had rebelled at the downloading-induced sluggishness and tried to tell me. Shaky and off balance, new to the planet and the flesh I was wearing, I had ignored it. The download dues had taken their toll.

Below on the lawn, Miriam Bancroft was still watching me. I backed away from the telescope, composed my features and returned to my seat. Absorbed by the images I had faked into his head, Bancroft seemed scarcely to know that I had moved.

But now my own mind was in overdrive, ripping along avenues of thought that had opened with Ortega’s list and the Resolution 653 T-shirt. The quiet resignation I had felt in Ember two days ago, the impatience to sell my lies to Bancroft, get Sarah out and be finished were all gone. Everything tied in to Head in the Clouds, ultimately even Bancroft. It was almost axiomatic that he had gone there the night he died. Whatever had happened to him there was the key to his reasons for dying here at Suntouch House a few hours later. And to the truth that Reileen Kawahara was so desperate to hide.
