That was one mystery solved, but it begged more questions than it answered. Why had Delphine alighted on this subject matter, so many decades after Lascaille's return? And why had her decision to portray Lascaille resulted in a work of such striking emotional resonance, when her creations had been so affectless before?
On this, the compad had nothing to say.
Sparver continued with his meal, wondering how far ahead of him Dreyfus's enquiries had reached.
He could still feel the eyes on his neck.
'Back from whatever busy errand called you away last time, Prefect Dreyfus?' asked the beta-level invocation of Delphine Ruskin-Sartorious.
âI'm sorry about that,' Dreyfus said. âSomething came up.'
âConnected with the Bubble?'
âI suppose so.' His instincts told him that Delphine didn't need to know all the details concerning Captain Dravidian. âBut the case isn't closed just yet. I'd like to talk to you in some detail concerning the way the deal collapsed.'
Delphine reached up and pushed a stray strand of hair back under the rag-like band she wore around her head. She was dressed in the same clothes she'd been wearing during the last invocation: white smock and trousers, sleeves rolled to the elbow, trousers tucked up to the knee. Once again Dreyfus was struck by the paleness of her eyes and the doll-like simplicity of her features.
âHow much did Vernon tell you?' she asked.
âEnough to know that someone called through and that was enough to remove Dravidian's offer from consideration. I'd really like to know who that mystery caller was.'
âA representative of some other group of Ultras, intent on undermining Dravidian. Does it really matter now?'
âPlay along with me,' Dreyfus said. âAssume for a minute that Dravidian was set up to make it look as if he intentionally fired on you. What reason might there have been for someone to want to hurt your family?'
Her face became suspicious. âBut it
was
revenge, Prefect. What else could it have been?'
âI'm simply keeping an open mind. Did you or your family have enemies?'
âYou'd have to ask someone else.'
âI'm asking you. What about Anthony Theobald? Had he crossed swords with anyone?'
âAnthony Theobald had friends and rivals, like anyone. But actual enemies? I wasn't aware of any.'
âDid he leave the habitat often?'
âNow and then, to visit another state or go down to Chasm City. But there was never anything sinister about his movements.'
âWhat about visitors - get many of those?'
âWe kept ourselves to ourselves, by and large.'
âSo no visitors.'
âI didn't say that. Yes, of course people came by. We weren't hermits. Anthony Theobald had his usual guests; I had the occasional fellow artist or critic.'
âNone of whom would have had any pressing reason to see you dead?'
âSpeaking for myself, no.'
âAnd Anthony Theobald - what were his guests like?'
He caught it then: the tiniest flicker of hesitation in her answer. âNothing out of the ordinary, Prefect.'
Dreyfus nodded, allowing her to think he was content to let the matter stand. He knew he'd touched on something, however peripheral it might prove, but his years of experience had taught him that it would be counterproductive to dig away at it now. Delphine would be conflicted between her blood loyalty to Anthony Theobald and her desire to see justice served, and too much probing from him now might cause her to clam up irrevocably.
He would have to earn her trust.
âThe point is,' she went on, âI really wasn't interested in family or Glitter Band politics. I had - have - my art. That was all that interested me.'
âLet's talk about your art, then. Could someone have been jealous of your success?'
She looked stunned. âEnough to kill nine hundred and sixty people?'
âCrimes aren't always proportionate to motive.'
âI can't think of anyone. If I'd been the talk of Stoner society, we wouldn't have been dealing with a second-rate trader like Dravidian.'
Dreyfus bit his tongue, keeping his policeman's poker face fixed firmly in place. âAll the same, someone wanted you all dead, and I'll sleep easier when I know the reason.'
âI wish I could help.'
âYou still can. I want you to tell me when that call came through.'
âWhile Dravidian was visiting us.'
âIf you could narrow it down, that would help.'
The beta-level closed her eyes momentarily. âThe call came in at fourteen hours, twenty-three minutes, fifty-one seconds, Yellowstone Standard Time.'
âThank you,' Dreyfus said. âFreeze-' he began.
âAre we done?' Delphine asked, cutting him off before he had finished issuing the command.
âFor now. If there's anything else I need from you, you'll be the first to hear about it.'
âAnd now you're going to put me back in the box?'
âThat's the idea.'
âI thought you wanted to talk about art.'
âWe did.'
âNo, we discussed the possibility of my art being a motivating factor in the crime. We didn't discuss the art itself.'
Dreyfus shrugged easily. âWe can, if you think it's relevant.'
âYou don't?'
âThe art appears to be a peripheral detail, unless you think otherwise. You yourself expressed doubt that jealousy could have been a motivating factor.' Dreyfus paused and reconsidered. âThat said, your reputation was building, wasn't it?'
Delphine looked at him sourly. âYou make it sound as if my life story's already written, down to the last footnote.'
âFrom where I'm standing ...' But then Dreyfus remembered what Vernon had told him concerning Delphine's belief in the validity of beta-level simulation.
âWhat?' Delphine said.
âThings will be different. Won't they?'
âDifferent. Not necessarily worse. You still don't believe in me, do you?'
âI'm trying my best,' Dreyfus replied.
âThe last time we spoke, I asked you a question.'
âDid you?'
âI asked you if you'd ever lost a loved one.'
âI answered you.'
âEvasively.' She fixed him with a long, searching stare. âYou have lost someone, haven't you? Not just a colleague or friend. Someone closer than that.'
âWe've all lost people.'
âWho was it, Prefect Dreyfus? Who did you lose?'
âTell me why you chose to work on the Lascaille series. Why did you care about what happened to a man you never knew?'
âThose are personal questions for an artist.'
âI'm wondering if you made any enemies when you picked that theme.'
âAnd I'm wondering why you find it so difficult to acknowledge my conscious existence. This person who died - did something happen that made you turn against beta-levels?' Her eyes flashed an insistent sea-green, daring him to look away. âWho was it, Prefect? Quid pro quo. Answer my question and I'll answer yours.'
âI've got a job to do, Delphine. Empathising with software isn't part of it.'
âI'm sorry you feel that way.'
âNo,' Dreyfus said, something inside him snapping, âyou aren't “sorry. âSorry” would imply the presence of a thinking mind, a sentient will capable of experiencing the emotion called regret“. You're saying that you are sorry because that's what the living Delphine would have said under similar circumstances. But it doesn't mean you feel it.'
âYou really don't think I'm alive, in any sense of the word?'
âI'm afraid not.'
Delphine nodded coolly. âIn which case: why are you arguing with me?'
Dreyfus reached for an automatic answer, but nothing came. The moment dragged, Delphine regarding him with something between amusement and pity. He froze the invocation and stood staring at the empty space where she had been standing.
Not a she, he told himself. An it.
'Hello?' Thalia called into an echoing, dank darkness. âThis is Deputy Field Prefect Ng. Is anyone there?'
There was no answer. Thalia stopped and put down the heavy cylinder she'd been carrying in her left hand. She touched her right hand to the haft of her whiphound, and then chided herself for her unease. Letting go of the weapon, she extracted her glasses, slipped them on and keyed image-amplification. The darkness of the chamber abated, revealing a doorway in one wall. Thalia touched the glasses again, but the entoptic overlay changed nothing. If a habitat citizen had been standing in Thalia's place with a skullful of sense-modifying implants, they'd still have seen only the same drab walls.
âMoving deeper into the hab,' Thalia said, reporting back to her cutter. âSo far I'm not exactly overwhelmed by the welcoming committee.'
She picked up the equipment cylinder in her left hand. Caution prevailed, and this time she chose to release the whiphound. âProceed ahead of me at defence posture one,' she instructed, before letting go. Red eye bright, the whiphound nodded its haft once to indicate that it had understood her order and was now in compliance. Then it turned the haft away from her and slunk forward, gliding across the ground on the coiled tip of its filament, like a sketch of a cobra.
The doorway led to a damp tunnel with cracked flooring. Ahead, the tunnel began to curve around. The whiphound slinked forward, the red light of its scanning eye reflecting back from moist surfaces. Thalia followed it into the tunnel, around a gentle curve, until the tunnel widened out into a gloomily lit plaza. The curvature of the habitat was evident in the continuous gentle up-sweep of the floor, rising ahead of her until it was hidden by the similarly curving ceiling. The only illumination came from sunlight creeping through immense slatted windows on either side, their glass panes tinting the light sepia-brown through a thick caking of dust and mould. Rising high above Thalia, interrupted only by the windows, were multi-levelled tiers of what had once been shops, boutiques and restaurants. Bridges and ramps spanned the space between the two walls, some of them sagging or broken. Glass frontages lay shattered, or were covered with various forms of mould or foliage-like infestation. In some of the shops there was even evidence of unsold merchandise, cobwebbed into obscurity.
Thalia didn't like the place at all. She was glad when she found another tunnel leading out of the plaza. The whiphound slinked ahead of her, its coil making a rhythmic hissing sound against the flooring.
Without warning, it vanished.
An instant later Thalia heard a sound like two pieces of scrap metal being smashed against each other. Cautiously she rounded the curve and saw the whiphound wrapped around the immobilised form of a robot, which had toppled over onto its side, its rubber-tyred wheels spinning uselessly. Thalia stepped closer, putting down the cylinder. She appraised the fallen machine for weapons, but there was no sign that it was anything other than a general-purpose servitor of antique design.
âRelease it,' she said.
The whiphound uncoiled itself and pulled back from the robot, while still keeping its eye locked on the machine. Laboriously, the robot extended telescopic limbs to right itself. A slender pillar rose from the wheeled base, with limbs and sensors sprouting at odd, asymmetric angles from the pillar.
âI am Deputy Field Prefect Thalia Ng, of Panoply,' she said. âIdentify your origin.'
The robot's voice was disconcertingly deep and emphatic. âWelcome to Carousel New Seattle-Tacoma, Deputy Field Prefect Ng. I trust your journey was pleasant. I apologise for my lateness. I have been tasked to escort you to the participatory core.'
âI was hoping to talk to Citizen Orson Newkirk.'
âOrson Newkirk is in the participatory core. Shall I assist you with your luggage?'
âI can manage,' Thalia said, shaking her head.
âVery well, Deputy Field Prefect Ng. Please follow me.'
âWhere is everyone? I was expecting a population of one point three million people.'
âThe current population is one million, two hundred and seventy-four thousand, six hundred and eighteen people. All are accounted for in the participatory core.'
âYou keep saying that - what's a participatory core“?'
âPlease follow me.'
The robot spun around, tyres hissing against the wet flooring, and began to amble down the corridor, trailing an electrical burning smell in its wake.
From seven and a half metres away Jane Aumonier smiled tightly. âYou're like a dog with a bone, Tom. Not everything in life is a conspiracy. People do sometimes get mad and do stupid and irrational things.'
âDravidian sounded neither mad nor irrational to me.'
âOne of his crew, then.'
âActing according to plan. Following a script to make the whole attack look like a heat-of-the-moment thing, when in fact it was set up long before Dravidian ever met Delphine.'
âYou really think so?'
Dreyfus had just run the Solid Orrery in his room. He'd backtracked the configuration of the Glitter Band to the time when Delphine Ruskin-Sartorious said the call had come in. The data was now sitting in Thalia's cutter, waiting for her to get to it when she completed her current upgrade.
âYou've always trusted my instincts in the past,' Dreyfus said. âNow they're telling me that there's so mething going on here that we're supposed to overlook.'
âYou've spoken to the betas?'
