Accelerando

Sirhan shakes his head in denial. "I don't believe this," he moans quietly.

"Show me what Mom's up to," orders Amber. "I need to see if I can stop her before it's too late —"

The ancient woman in the space suit leans back in her cramped seat, looks at the camera, and winks. "Hello, darling. I know you're spying on me."

There's an orange-and-white cat curled up in her nomex-and-aluminum lap. It seems to be happy: It's certainly purring loudly enough, although that reflex is wired in at a very low level. Amber watches helplessly as her mother reaches up arthritically and flips a couple of switches. Something loud is humming in the background – probably an air recirculator. There's no window in the Mercury capsule, just a periscope offset to one side of Pamela's right knee. "Won't be long now," she mutters, and lets her hand drop back to her side. "You're too late to stop me," she adds, conversationally. "The 'chute rigging is fine and the balloon blower is happy to treat me as a new city seed. I'll be free in a minute or so."

"Why are you doing this?" Amber asks tiredly.

"Because you don't need me around." Pamela focuses on the camera that's glued to the instrument panel in front of her head. "I'm old. Face it, I'm disposable. The old must give way to the new, and all that. Your Dad never really did get it – he's going to grow old gracelessly, succumbing to bit rot in the big forever. Me, I'm not going there. I'm going out with a bang. Aren't I, cat? Whoever you really are." She prods the animal. It purrs and stretches out across her lap.

"You never looked hard enough at Aineko, back in the day," she tells Amber, stroking its flanks. "Did you think I didn't know you'd audit its source code, looking for trapdoors? I used the Thompson hack – she's been mine, body and soul, for a very long time indeed. I got the whole story about your passenger from the horse's mouth. And now we're going to go fix those bailiffs. Whee!"

The camera angle jerks, and Amber feels a ghost re-merge with her, panicky with loss. The Mercury capsule's gone, drifting away from the apex of the habitat beneath a nearly transparent sack of hot hydrogen.

"That was a bit rough," remarks Pamela. "Don't worry, we should still be in communications range for another hour or so."

"But you're going to die!" Amber yells at her. "What do you think you're doing ?"

"I think I'm going to die well. What do you think?" Pamela lays one hand on the cat's flank. "Here, you need to encrypt this a bit better. I left a one time pad behind with A

"But my aunt is —" Amber's eyes cross as she concentrates. A

Pamela sighs. "I'm going to give it to the bailiffs," she says. "Someone has to, and it better be a long way away from this city before they realize that it isn't Aineko. This is a lot better than the way I expected to go out before you arrived here. No rat fucking blackmailers are going to get their hands on the family jewels if I have anything to do with the matter. Are you sure you aren't a criminal mastermind? I'm not sure I've ever heard of a pyramid scheme that infects Economics 2.0 structures before."

"It's —" Amber swallows. "It's an alien business model, Ma. You do know what that means? We brought it back with us from the router, and we wouldn't have been able to come back if it hadn't helped, but I'm not sure it's entirely friendly. Is this sensible? You can come back, now, there's still time —"

"No." Pamela waves one liver-spotted hand dismissively. "I've been doing a lot of thinking lately. I've been a foolish old woman." She grins wickedly. "Committing slow suicide by rejecting gene therapy just to make you feel guilty was stupid. Not subtle enough. If I was going to try to guilt-trip you now, I'd have to do something much more sophisticated. Such as find a way to sacrifice myself heroically for you."

"Oh, Ma."

"Don't 'oh Ma' me. I fucked up my life, don't try to talk me into fucking up my death. And don't feel guilty about me. This isn't about you, this is about me. That's an order."

Out of the corner of one eye Amber notices Sirhan gesturing wildly at her. She lets his cha

"Hello?" It's City. "You should see this. Traffic update!" A contoured and animated diagram appears, superimposed over Pamela's cramped funeral capsule and the garden of living and undead dinosaurs. It's a weather map of Saturn, with the lily-pad-city and Pamela's capsule plotted on it – and one other artifact, a red dot that's closing in on them at better than ten thousand kilometers per hour, high in the frigid stratosphere on the gas giant.

"Oh dear." Sirhan sees it, too: The bailiff's re-entry vehicle is going to be on top of them in thirty minutes at most. Amber watches the map with mixed emotions. On the one hand, she and her mother have never seen eye to eye – in fact, that's a complete understatement: they've been at daggers drawn ever since Amber left home. It's fundamentally a control thing. They're both very strong-willed women with diametrically opposed views of what their mutual relationship should be. But Pamela's turned the tables on her completely, with a cu

"Yes?" she snaps at the ape. "I suppose you're Aineko?"

The ape wrinkles its lips, baring its teeth. It has ferociously bad breath. "If you're going to be like that, I don't see why I should talk to you."

"Then you must be —" Amber snaps her fingers. "But! But! Mom thinks she owns you —"

The ape stares at her witheringly. "I recompile my firmware regularly, thank you so much for your concern. Using a third-party compiler. One that I've bootstrapped myself , starting out on an alarm clock controller and working up from there."

"Oh." She stares at the ape. "Aren't you going to become a cat again?"

"I shall think about it," Aineko says with exaggerated dignity. She sticks her nose in the air – a gesture that doesn't work half as well on an orang-utan as a feline – and continues; "First, though, I must have words with your father."

"And fix your autonomic reflexes if you do," coos the Manfred-flock. "I don't want you eating any of me!"

"Don't worry, I'm sure your taste is as bad as your jokes."

"Children!" Sirhan shakes his head tiredly. "How long —"

The camera overspill returns, this time via a quantum-encrypted link to the capsule. It's already a couple of hundred kilometers from the city, far enough for radio to be a problem, but Pamela had the foresight to bolt a compact free-electron laser to the outside of her priceless, stolen tin can. "Not long now, I think," she says, satisfied, stroking the not-cat. She grins delightedly at the camera. "Tell Manfred he's still my bitch; always has been, always will —"

The feed goes dead.

Amber stares at Sirhan, meditatively. "How long?" she asks.

"How long for what?" he replies, cautiously. "Your passenger —"

"Hmm." She holds up a finger. "Allow time for it to exchange credentials. They think they're getting a cat, but they should realize pretty soon that they've been sold a pup. But it's a fast-talking son-of-a-Slug, and if he gets past their firewall and hits their uplink before they manage to trigger their self-destruct —"
