The Quantum Thief

Unruh smiles. ‘Yes. A millennium of Time goes quickly, these days. I’m giving most of it away, and some of it will be managed by my associate – Odette, whom you already met.’

‘I understand it is rare among our generation – not to rail against the injustice of it all – but I’m something of an idealist. I believe in the Oubliette. I have had a rich eight years in this body; I’m ready to do my part as a Quiet. But of course, I want to conclude things with style, before the next time. To seize the day, for one night.’ There is an odd bitterness in his voice.

The Quiet servant hands them both fine porcelain cups of tea: Unruh tastes his with relish. ‘Also, finiteness gives everything such an edge, don’t you think? I think that’s what our founding fathers and mothers had in mind. Experiencing that is all I wanted. Until the note came along.’

‘How did it arrive?’

‘I found it in my library,’ Unruh says. ‘In my library!’ Hard anger lines look strange on his childlike face. His cup rattles when he sets it down. ‘I don’t let anyone in my library, M. Beautrelet. It is my inner sanctum. And no one outside my immediate circle of friends even has the gevulot to come to this castle. As I’m sure you can understand given your recent experiences with the press, I feel … violated.’

Isidore shudders. The thought of someone coming to his personal space, unannounced, without access to his gevulot makes his skin crawl. ‘You don’t think it is possible that this is a prank of some kind?’

Unruh presses his palms together. ‘I have considered the possibility, of course,’ he says. ‘As you can imagine, I went through the castle exomemory thoroughly. I found nothing. Sometime last night, between seven and eight thirty, the letter simply appeared. I don’t recognise the handwriting. The paper is from a stationery shop on the Avenue. There are no obvious DNA traces, apart from mine. That is as far as Odette got. I am convinced that offworld technology is involved. The modus operandi would certainly fit with what we know about this character – announcing a date and time for his crime.

‘In some way, I’m not surprised. The offworlders think that we are a backwater, a playground. And for some reason, this . . . thief has chosen me as his plaything. But if I went to the Voice or the tzaddikim, they would tell me the same thing: it is a prank. And that’s why you are here, M. Beautrelet.’ Unruh smiles. ‘I want you to help me. I want you to find out how the letter got into my library. I want you to figure out what he is going to do, and stop it. Or if he succeeds, recover what is mine.’

Isidore takes a deep breath. ‘I think you may have a somewhat exaggerated view of my abilities,’ he says. ‘I’m not convinced that this is the real le Flambeur by any means. But if it is, why do you think I will be a match for such a creature?’

‘As I said, I’m an idealist,’ Unruh says. ‘I am familiar with your work. Indeed, I consider myself to be something of a fan. And, while I am deeply insulted by the thief’s actions, I do find the thought of having my demise accompanied by a battle of wits amusing. Naturally, we can find a suitable compensation for your efforts, if that is an issue. What do you say?’

To catch a thief, Isidore thinks. Something pure. Something simple. Something clean. Even if it turns out to be a joke.

‘All right,’ he says. ‘I accept.’

Unruh slaps his hands together. ‘Excellent! You know, M. Beautrelet, you are not going to regret your decision.’ He gets up. ‘Now, let’s find Odette and visit the scene of the crime.’

The chateau is built with the same grandeur as the Kingdom simulation at the zoku colony: high ceilings, marble floors, matte black suits of robotic armour lining the corridors along with large landscape paintings of old Mars: red cliffs, Valles Marineris, the grinning visage of the King in white and gold.

Odette – the woman in white – is waiting for them in the library, and gives Isidore a curt nod when they enter.

‘Well done,’ Unruh tells her. ‘It appears that your charms persuaded young M. Beautrelet to assist us with our little dilemma.’

‘I thought he might,’ she says. ‘I think you will find this interesting, M. Beautrelet.’

The library is a high room, well-lit by a skylight, with large windows to the garden. There are comfortable-looking leather couches. And books, both analog and spime, thousands of them in neat rows in dark oak shelves, attended to by a treelike synthbio drone. A large brass orrery – metal casing containing a real-time image of Mars and the surrounding space – sits in the centre of the room on a dark wine-coloured rug.
