'Jesus,' she said. 'They bumped him. Uncle Zip bumped his own guy.'

'I don't think it was Uncle Zip,' the mathematics said. 'The command came from somewhere else in the ship.' A dry laugh. 'It's like the bicameral mind in there.'

Seria Mau felt weepy when she heard this.

'It was the commander,'she said. 'He always liked me. And I always liked him.'

'You don't like anyone,' the mathematics pointed out.

'Usually I don't,' said Seria Mau. 'But I'm very up and down today. I can't work out what's the matter with me.' Then she said: 'Where's that bastard Moire?'

'He's down in the outer layers of the gas giant. He got out by surfing the expansion wave of the bump. He's taken damage, but his engines still work. Do you want to go in after him?'

'No. Cook it up.'

'Pardon?'

'Cook the fucker up.'

'?'

'If you want something done,' sighed Seria Man, 'do it yourself. There.' Ordnance disengaged from one of the complex outer structures of the White Cat, hung for the blink of an eye while its engine fired, then streaked down into the gas giant's atmosphere. Gravity tried to crush it out of existence, but between here and there it had turned itself into the voice of God. Something like lightning flared across the face of the gas giant, as it began to torch itself up. Uncle Zip opened a line to the White Cat. He was puffing out his cheeks angrily. 'Hey,' he said, all that was unnecessary. You know? I paid good money for those guys. In the end I wouldn't of let them hurt you.'

Seria Mau ignored him.

'Better light out,' she advised her mathematics. She yawned. 'This is where we're going,' she said. And finally: 'I really didn't want to be bothered with that fucker again. I was just too tired.'

As they left the system, a new star had begun to burn behind them.

Seria Mau slept for a long time, dreamlessly at first. Then she began to see images. She saw the New Pearl River. She saw the garden, gloomy under rain. She saw herself from a great distance, very small but clear. She was thirteen. She had gone to sign up for the K-ships. She was saying goodbye to herbrother and her father. The scene was this: the station at Saulsignon, still pretty under its wartime skies, which were just like the wartime skies of Antique European Earth, blue, turbulent, vapour-trailed but full of hope. She saw herself wave, and she saw the father raise his hand. The brother refused to wave. He didn't want her to go, so he refused even to look at her. This scene faded slowly. After that, she glimpsed herself when she was last human, sitting on the edge of a bed shivering, vomiting into a plastic bowl while she tried to hold around her a cotton robe that fell open constantly at the back. You sign up for the K-ships in sterile white rooms at even temperatures: nevertheless, whatever you do you can't get warm. You mustn't have eaten. They give you the emetics anyway. They give you the injection. They give you the tests, but to be honest that is only to pass the two or three days it takes the injection to work. By then your bloodstream is teaming with selected pathogens, artificial parasites and tailored enzymes. You present with the symptoms of MS, lupus and schizophrenia. They strap you down and give you a rubber gag, to bite on. The way is cleared for the shadow operators, running on a nanomech substrate at the submicrometre level, which soon begin to take your sympathetic nervous system to pieces. They flush the rubbish out continually through the colon. They pump you with a white paste of ten-micrometre-range factories which will farm exotic proteins and monitor your internal indicators. They core you at four points down the spine. You are conscious all the way through this process, except for the brief moment when they introduce you to the K-code itself. Many recruits, even now, don't make it past that point. If you do, they seal you in the tank. By then they have broken most of your bones, and taken some of your organs out: you are blind and deaf, and all you are aware of is a kind of nauseous surf rolling through you forever. They have cut into your neocortex so that it will accept the software bridge known ironically as 'the Einstein Cross' from the shape you see the first time you use it. You are no longer alone. You will soon be able to consciously process billions of billions of bits per second; but you will never walk again. You will never laugh or touch someone or be touched, fuck or be fucked. You will never do anything for yourself again. You will never even shit for yourself again. You have signed up. It comes to you for an instant that you were able to choose this but that you will never, ever, ever be able to unchoose it.

In the dream, Seria Mau saw herself from above. All these years on, she wept at what she had done to herself back then. Her skin was like a fish's skin. She was trembling in the tank like a damaged experimental animal. But her brother would not even wave her goodbye that day. That in itself was reason enough. Who wanted a world like that, where you had to be the mother all the time, and your brother wouldn't even wave goodbye?

Abruptly Seria Mau was looking at a picture of a blank interior wall covered with ruched grey silk. After some time, the upper body of a man- he was tall, thin, dressed in a black tailcoat and starched white shirt; he held in one white-gloved hand a top hat, in the other an ebony cane-bent itself slowly into the frame of the picture. Seria Mau trusted him immediately. He had laughter in his eyes- they were a penetrating light blue-and a black pencil moustache, and his jet-black hair was brilliantined close to his head. It occurred to her that he was bowing. After a long while, when he had bent as much of his body into her field of vision as he could without actually stepping into it, he smiled at her, and in a quiet, friendly voice said:

'You must forgive yourself all this.'

'But -' Seria Mau heard herself reply.

At this, the ruched silk background was replaced by a group of three arched windows opening on to the blunt glare of the Kefahuchi Tract. This made the room itself appear to be toppling through space at a measured, subrelativistic pace.

'You must forgive yourself for everything,' the conjuror said.

Slowly, he tipped his hat to her, and bowed himself back out of the picture. Before he had quite gone, he beckoned her to follow him. She woke up suddenly.

'Send the shadow operators to me,' she told her ship.

TWENTY-SEVEN

The Alcubiere Break

Ed's fishtank movie showed him his sister leaving again.

'But will you come back?' the father begged her. There was no answer to that. 'But will you?'

Ed wrenched his head around on his neck as far as it would go, stared at anything-the flower tubs, the white cumulus clouds, the tabby cat -so as not to look at either of them. He wouldn't have a kiss from her. He wouldn't wave goodbye. She bit her bottom lip and turned away. Ed knew this was a memory. He wished he could piece it together with the other stuff he remembered, make sense of the shitty retrospective project of his life. But her face wavered as if behind water, decoherent and strange, and suddenly he was right through it and out the other side.

Everything lurched as hewent through, and there was nothing but blackness and a sense of enormous speed. A few dim points of light. A chaotic attractor churning and boiling in the cheap iridescent colours of 400-year-old computer art. Like a wound in the firmament.

'You believe this shit?' Ed said.

His voice echoed. Then he was out the other side of that too, and toppling in empty space forever, where he could hear the precise roaring surf of the songs of the universe, nested inside each other like fractal dimensions-and then woke and found he was still on stage. It was unusual for that to happen, and maybe what had wakened him was this unlooked-for noise he had heard, swelling up to penetrate his prophetic coma like the sound of the waves as they fall on Monster Beach. He opened his eyes. The audience, still on its feet, was applauding him for the third solid minute. Of them all, Sandra Shen was the only one still seated. Eyeing him from the front row with an ironic smile, she tapped her little oriental paws slowly together. Ed leaned forward to try and hear the sound they made. Fainted.
