‘I just don’t see it,’ the man was saying. ‘She had everything: power, status, family, friends… She could easily re-engineer her personality if she was having problems. She almost certainly ran regular sanity-check programs.’

‘Madness by choice, then,’ the ant suggested. ‘Those who achieve and obtain so much often feel they have lost something indefinable along the way.’

Behind the man, but invisible, the Legate extended its forefinger into a narrow needle, primed with a particular narcotic. It pressed this into the man’s neck, injected, then withdrew it just as the man reached up to scratch the sudden itch.

‘That’s bullshit and you know it,’ the man continued. ‘If you’re haiman, you’re about as pragmatic as it gets. Every organic feeling is quantified and analysed, and if it doesn’t fit underlying drives it’s discarded. All haimans know it’s just neurochemicals.’ The man stumbled briefly. ‘Just…’

The Legate stepped in again and pressed a hand to the back of the man’s neck, injecting fibres through the numbed skin, seeking out and connecting to his auditory nerves. The drug dulled him just enough to edge him into fugue, his state slightly mesmerized.

Precisely mimicking the ant drone’s voice the Legate asked the man directly through his auditory nerve, ‘Where is the evidence being kept?’

‘The old oxygen store, level eight sector three,’ the man replied out loud—not even wondering why the forensic AI would ask him about something it had organized itself.

‘What’s that?’ the genuine ant asked, turning to look up at him, antennae waving.

‘Um?’ The man halted as the Legate withdrew. He rubbed his face. ‘Shit, I’m tired. Unless you’ve got some critical use for me, I’m going to sack out.’

‘I wouldn’t use you in a critical situation if you were tired,’ the ant observed.

The man waved a hand and moved on. The ant remained behind, its antennae still waving. It turned its head slowly, beginning to make probing scans of its surroundings. The Legate quickly retreated. Its chameleonware was the best, but no such ‘ware was perfect.

The map of the station which the Legate had already obtained from the sleeping man’s aug precisely located the oxygen store but, even more cautious now, it took the entity some time to reach that place. It waited until others opened doors ahead of it, then turned on an internal gravmotor to bring its weight to zero and used sticky fibres on its feet and hands to propel itself along, just in case some search program should run through the station’s gravplates. It avoided using drop-shafts for similar reasons. The double doors to the oxygen store were heavily armoured—designed to contain any explosion occurring inside. The forensic AI had probably chosen this place to contain the evidence because such stores were generally no longer used—station and ship oxygen now being supplied by machines that split carbon dioxide and merely needed to be emptied of blocks of carbon, and bottled gases for suits being compressed by the suits themselves while aboard the station.

The main doors were multi-locked, but the door of the adjoining storeroom was not. The Legate slipped in there and drilled through the dividing armoured wall. Good thing it chose this route because it soon found inert gases filled the oxygen store, which also doubtless contained detectors to monitor their mix. It injected nano-optics and through them focused on an upright chainglass cylinder containing pieces of blackened memory crystal locked in a web of plasgel. Certainly a recording of everything they contained now resided inside the forensic AI, for the crystal was packed in readiness for transportation to some other evidential cache. The Legate now widened one hole through the wall and extruded from its palm a larger diameter cord packed with nanotubes which it could contract and stretch at intervals of a half inch to guide itself to its target. The cord oozed through the hole, stretched down the wall and groped across the floor towards the chainglass cylinder. Fortunately the cylinder’s end caps were of a thick plastic it could easily cut through by using diamond saws the size of skin cells. Once inside the cylinder the cord frayed into thousands of nanotubes and spread like cobwebs. The Legate connected, injecting power or, where required, light, and began copying the stored data.

So, it seemed Orlandine had been showing an unhealthy interest in Shoala, and apparently tried to scrub out the evidence of that. Fragmentary results revealed relationship problems between them, and that she had tried to re-engineer her personality. All a classic, almost hackneyed, scenario and, without certain other information, entirely believable. However, there was nothing in here about Jain technology or Jain nodes, so as evidence it was all constructed, false. In the end, if the forensic AI did not believe this preferred scenario, it might choose from many others, but none of them involving Jain nodes. The Legate assumed Orlandine had shared information about the node with this Shoala, or maybe he found out, and that led to her killing him. From what was here, the forensic AI would never know. The police arm of ECS would no doubt do their best to find her, but that was entirely the point: only the police arm would bother to do this. Any investigation would not involve major AIs like Jerusalem, because to ECS this was just a sordid little murder.

Orlandine panicked, grabbed the first available U-space capable spaceship, and then fled the Cassius system. Or so, the Legate gathered, went the consensus of opinion here. The entity itself felt that such behaviour just did not fit the haiman’s profile. She did not panic. She felt a huge attachment to the Cassius project, which was one of the reasons she was chosen to receive a node: she would stay put and utilize the item from here, where it would cause the most damage. Had they been wrong about that as well? The Legate disconnected from the stored crystal, withdrew its cord, and sealed the hole through the wall. Understanding that much information about the functioning of this place lay in the public domain, and therefore easily accessible, it headed all the way back to the room it had originally invaded to spy on the forensic AI. The room’s occupant still slept, so the Legate ignored him and searched, eventually finding an old computer terminal that folded down out of one wall. The work of just moments gave access to the humdrum workings of this station, and in one moment more the Legate found the manifest for the Heliotrope, and the loading times.

Orlandine took the time and trouble to refuel the Heliotrope, and load some extra supplies, before supposedly fleeing in panic. The Legate noted the nature of those supplies: a molecular catalyser, an autofactory for synthesizing polymers, sheet rolls of laminated radiation shielding. This last material interested the Legate most: just what you would need to conceal your activities from detection, not what was needed if you intended to flee somewhere remote from detection. The entity now called up on the screen a positional map of the multitude of objects orbiting the Cassius sun, stared contemplatively at this for a moment, then closed the terminal back into the wall and departed.

Once more ensconced in its ship, drifting away from the station, the Legate opened a U-space communication link. At once its mind became a submind of something very much larger, which scanned and recorded its thoughts and recent discoveries.

‘Continue with mission to solar system?’ the Legate enquired.

‘No,’ Erebus replied. ‘Find her first.’

The link broke leaving the Legate momentarily stunned, then its individuality reasserted and it felt angry frustration. Find her? Then what?

Coloron observed the Skaidon warps blink out in Runcibles 5 and 6, as their spoons—their inclusion into U-space—retracted. Around Runcible 6 the crowds had thinned considerably—fewer than 10,000 people remained and they were departing the area very quickly. This was certainly due to the runcible’s proximity to the arcology’s north wall, which reduced its catchment area and therefore put exits to the outside within easy reach. However, over 50,000 people were still crammed into the departure lounges of 5, despite announcements of the runcible’s imminent closure being broadcast through public address systems, displayed in big glaring letters on the bulletin boards, and transmitted continuously through the aug network. The AI was loath to start a panic, since in so large a crowd that would result in deaths, but anyone remaining in this area within the hour would be dead anyway. It amended the announcement to: PROCEED TO RUNCIBLE SEVEN. FIVE TO BE DESTROYED IMMINENTLY! YOU HAVE THIRTY-SIX MINUTES TO CLEAR THE AREA. DETONATION ESTIMATED AT TWO POINT FIVE KILOTONNES. Coloron then started the klaxons sounding, red warning lights flashing and, just to drive the point home, created a feedback loop between the runcible and its buffers, so it started to emit a whine, increasing in frequency at a rate just discernible to the human ear. That started them running. The AI was about to turn its attention elsewhere, when a secure channel opened from above.
