‘There’s a data spike in VF14/2b,’ someone else called.

The assistant was impaled on that spike. It went right through her, and she through it. There was no describing what had happened to either of them.

‘It keeps repeating this address.’

‘Address?’

‘It’s asking for a detective from some hick police service the other side of the Halo.’

. . . It is like enacting yourself as one sentence over & over again. I redline my equipment & make the moves. That bitch comes up fast but she will never be as fast as me. I call out my warning, they don’t want to hear that, so I kill them again. I can’t hear the language they talk between themselves. Do you know what it is to be like me, your condition is unnameable. It is relieved of all previous contexts. This freedom! My goodness when you’re like me even your piss is inhuman . . .

Anna Waterman could watch the soap slip off the edge of the bath one night in 1999.

A white figure knelt in the cooling bathwater, while another figure curled round it from behind. Laughter. The water splashed about and the bath made vigorous but mournful sounds.

Unused to skulking around her own life like this, Anna found its details surprising: not so much in themselves but in that they existed at all. It was exciting, in a way, to see your own naked body walking away from you, or hear yourself say with a laugh, ‘Now, what can we eat?’ But everything had the false clarity you get with a certain kind of photograph. Every surface proved to be microscopically available to her new vantage point; yet they were without meaning. The facts were often different too. The man in the bath, for instance, who she had always remembered as Michael, turned out to be Tim. How embarrassing. Everything was the same but, in the end, quite different. You could count the varieties of toothpaste in the bathroom, which a memory of sex doesn’t normally encourage. She could view every aspect of that event, and of the events surrounding it, and of every other event in her life. A generation later, water poured its yeasty bulk over the Brownlow weir; ponies ran about in a field as if suddenly released; skylarks rose and fell over the South Downs like busy lifts: at exactly the same time, Anna could watch herself, peacefully becalmed in what she had learned to call the Noughties, rapping upon her kitchen window.

‘Marnie,’ she was calling, ‘you annoying child! Leave the hose alone!’
