The Quantum Thief

couple in Revolutionary white, with a child in tow gives her a strange look. Clumsily, she tries to think at her visitor’s gevulot interface. Private. An odd, stifled sensation tells her that she is now a placeholder to those around her.

Gevulot. Of course. I am an idiot. There is a boundary in her memories, between those which are local and exo. The thief passed her a co-memory of them talking, from seconds before, and her primitive gevulot accepted it. I was talking to a memory.

Mieli’s self-loathing is sudden and sharp. It reminds her of the smartcoral infection she had as a child, sharp spikes growing from her teeth and pressing painfully into the gums. Karhu cured her with a song, but it was impossible not to poke the protrusions with her tongue. She swallows the feeling, and focuses on the biot feed.

It is difficult to work without resorting to the metacortex and revealing it to the sniffers. So she just tries to focus on the part of her mind that is connected to the thief’s. It feels like trying to reconnect with a phantom limb. She closes her eyes and focuses—

‘Lady, have pity,’ says a voice, coarse and ragged. There is a naked man standing in front of her, intimate areas tastefully censored by a grey gevulot blur. His skin is pale, and he has no hair. His eyes are red-rimmed, and he looks like he has been crying. The only object on his body is a Watch, a thick metallic band with a clear crystal disc, dangling from one scrawny arm.

‘Have pity,’ he says. ‘You come from the stars; you will spend a few luxurious moments here and then go back to plenty, to immortality. Have pity on someone who only has a few moments of this life left, before being forced to atone for my sins, before they come and take my soul and cast it into the maw of a tongueless machine so I cannot even cry out in pain—’

Are you okay? Perhonen asks. What is happening?

Mieli tries the same basic gevulot trick as before – complete privacy – to exclude the madman from her horizon and vice versa – but the gevulot layer simply informs her that she has entered into a gevulot contract with another individual guaranteeing mutual superficial observation for the next fifteen minutes.

There is a naked madman in front of me, she tells the ship, helpless.

I thought he escaped.

‘If I could only beg you to share a few worthless seconds, insignificant slivers of your time, I would reveal all my secrets to you. I was a Count in the King’s Court, no less, a Noble, not as you see me now, but with a robotic castle of my own and a million gogols to do my bidding. And in the Revolution, I fought in the troops of the Duke of Tharsis. You should see the true Mars, the old Mars, I will give you all that for only a few seconds—’ Tears are streaming down the long, pale face now. ‘I have only dekaseconds, have pity—’ Cursing, Mieli gets up and starts walking, just to get away from the man, and notices a sudden hush. She is standing right in the middle of the agora.

Here, the Martians walk with exaggerated care. No one acknowledges anyone else. Tourists – a few Quick Ones, like fireflies, a delicate-limbed polymorph from Ganymede-zoku, and a few others, turn from inspecting the engraved names on the Revolution monument through floating smartmatter lenses to look at her.

The man is clinging to the hem of her toga. ‘One minute, even, a few seconds, for all the secrets of old Mars—’ He is completely naked now, unprotected by gevulot in the agora. She brushes his arm aside, with mere human strength instead of tearing it from its socket. But he lets out a high-pitched yelp, and collapses to the ground at her feet, still clinging to her garment and moaning. Suddenly, she is certain that everybody is looking at them, although it seems that no one is.

‘All right,’ she says, lifting her Watch, a crystalline model she chose because it looked like Oortian jewellery. ‘Ten minutes. It will take me longer than that to get rid of you.’ She thinks at the device, and the golden dial moves a fraction. The beggar leaps up, licking his lips.

‘The ghost of the King bless you, lady,’ he says. ‘The stranger said you were generous.’

‘The stranger?’ asks Mieli, even though she already knows the answer.

‘The stranger in the blue-tinted glasses, bless him, and bless you.’ A wide grin spreads across his face. ‘A word of warning,’ he says in a businesslike tone. ‘I would get out of this agora right now.’ Around Mieli, everybody, except the tourists are leaving. ‘Blood, water. I’m sure you understand.’ Then he springs into a naked run, scrawny legs carrying him away from the agora.

I am going to torture the thief, Mieli says. Blood and water? What did he mean by that?

On Earth, says Perhonen, there was this type of fish called sharks. I think the time beggars watch the public exomemory feeds, like from the agoras, no privacy there, so they would have seen you giving Time to a—

Suddenly, the agora is full of the sound of running bare feet, and Mieli finds herself face to face with an army of beggars.

I chase the boy through the Avenue crowd. He stays ahead of me, navigating the forest of legs with ease, his bare feet a blur, like the needle of a fabber. I elbow people aside, shouting apologies, leaving a trail of angry grey gevulot blurs in my wake.

I almost catch him at a spidercab stop, where the Avenue breaks into a hundred different alleys into the Maze. He stands in front of the long-legged machines, ornate horseless carriages with brass legs, curled up beneath them as they wait for passengers, looking at them in fascination.

I approach him slowly, in the crowd. He has different texture from everything else around me, sharper. Maybe it is the dirt on his face or the ragged brown garment he is wearing, or the dark brown eyes so different from those of the Martians. Only metres away—

But he is just taunting me. He lets out a faint peal of laughter as I lunge forward and slips under the long- legged cab carriages. I’m too big to follow and am left negotiating the crowd to get around the vehicles and their waiting passengers.

The boy is me. I remember being him, in my dream. The memories are pressed flat like a butterfly beneath the centuries, fragile, and fall apart when I touch them. There was a desert, and a soldier. And a woman in a tent. Maybe the boy is in my head. Maybe he is some construct that my old self left behind. Either way, I need to know. I shout his name, not Jean le Flambeur, but the older one.

A part of me is counting seconds to when Mieli manages to deal with her little distraction and shuts me down, or sends me to some new hell. I may only have minutes to find out what he has to tell me, without my minder looking over my shoulder. I catch a glimpse of him vanishing down an alley, into the Maze. I curse and keep running.

The Maze is where the larger platforms and components of the city collide, leaving spaces in between for hundreds of smaller jigsaw pieces that constantly move, forming occasional hills and winding alleyways that can slowly shift direction as you walk down them, so smoothly that the only way to tell is to see the horizon moving. There are no maps of the place, just firefly guides that brave tourists follow around.

I run a rough-cobbled steep slope downwards, lengthening my steps. Running on Mars is an art that I’ve never properly mastered, and as the street beneath lurches, I land badly after a particularly high leap, skidding down several metres.

‘Are you all right?’ There is a woman on a balcony above, leaning over the railing, clutching a newspaper.

‘I’m fine,’ I groan, fairly certain that the Sobornost body Mieli gave me is not going to break easily. But the simulated pain from the bruised tailbone is still pain. ‘Did you see a little boy go past?’

‘Do you mean that little boy?’

The rascal is less than a hundred metres away, doubled over with laughter. I scramble up and keep running.

Deep, deep into the Maze we go, the boy always ahead, always rounding a corner, never getting too far ahead, running across cobblestones and marble and smartgrass and wood.

We run through little Chinese squares with their elongated Buddhist temples, red and gold dragons flashing in their facades; through temporary marketplaces full of a synthfish smell, past a group of black-robed Resurrection Men with newly born Quiet in tow.

We race down whole streets – red lights districts, perhaps – blurred with gevulot, and empty streets where
