[It might. If nothing else, the Americans are now more scared of us than we are of them.]

“But they don’t learn, do they? They keep trying to slap us down, and we have to be quick every time. I’m afraid, Michael, that when it really matters, we’re going to be a fraction of a second too slow. Too slow for Lucy.”

[Then we must be ready for every eventuality, no matter how unlikely. I can calculate layer on layer of possibilities.]

“And still something might come out of nowhere and knock us off course.” Petrovitch stood up and put everything back in his pockets. “History’s not going to repeat itself, is it, Sonja? We’re too smart for that, right?”

She had no opinion to offer, one way or the other, so Petrovitch left her with the candle guttering in the fading daylight and made his way to the car, and the waiting Newcomen.

He unlocked the doors when he was still a good distance away, making the American jump. Newcomen’s phone was built into his tie: tucked down beside his now-sweat-stained collar was the earpiece. If it had been put together better, it would have been a poor imitation of Freezone tech. As it was, it was just a phone.

Petrovitch tagged it and made it ring.

“Hello?”

“Get in the car. You’ll catch a cold, and I’m not having you sneezing on me all the way across the Atlantic tomorrow.”

Newcomen crawled in, next to his luggage. “Doctor?”

“Yeah, we’re going to have to sort this out now. I only use the title when I want something, or you’ve pissed me off so much I won’t answer to anything else. Call me Petrovitch and have done with it.”

“That would be disrespectful, si… Doc… I can’t call you just ‘Petrovitch’. What would people think?”

“Oh, fuck off, Newcomen. Call me whatever you want. I don’t care. We’re going to find some dinner.”

It was getting dark, and the less salubrious side of the Metrozone was asserting itself. The authorities had reverted to the municipal model of government after the years’ hiatus of the Freezone. Petrovitch thought that his way of doing things was demonstrably better – an AI-administered co-operative had its own particular problems, but scaring off three desperate-looking men from robbing him wasn’t one of them.

He got closer to the car as they circled it. One of them had a half-brick, which wasn’t a surprise as they weren’t exactly in short supply. Knives, too. Perhaps they hadn’t spotted him, or maybe they had and thought that they could take this slight, short guy as well as the one crouched on the back seat. Petrovitch wasn’t armed, except for his weed-cutter, and Newcomen wouldn’t be allowed to carry outside his jurisdiction – unless Auden had slipped him a piece. Which would be typical of the man.

All three would-be thieves had phones. He tagged them and chased down their numbers, call histories, came up with a few houses over Wembley way where most of the calls geolocated. From there it was a short step to dragging identities off a database, bundling it all up with video footage of the current scene and posting it to the police.

They’d all be gone by the time anyone turned up, but he had an affection for the Metrozone that never went away. It was still his city, mean streets and all.

One of the men hefted the brick, circling the car with its terrified occupant.

“Don’t throw that,” Petrovitch called when he was within earshot. “Because then I’ll get pissed with you and you wouldn’t like it.”

There were no street lights outside the cemetery, and he switched to active infrared. Everything became so much clearer. He could see their hot bodies swaddled in thick clothes against the cold, could see their blood run bright. Meatsacks. So easily damaged.

He kept on walking: not a moment of falter or hesitation. Even when the brick was thrown at his head. He’d calculated the entire trajectory of the missile almost before it had left the man’s hand, and he didn’t need to so much as duck.

Petrovitch was beside the car. He rested his palm on its dusty roof and started it up, though he deliberately kept the headlights off. It was tempting to try the “don’t you know who I am?” line, but it was clear that in their in-between state of drugged joy and dragging withdrawal, they had no idea. The dull red glow coming from his eyes didn’t appear to jog their memories either.

“I’m happy to run you over. I’m equally happy for you to disappear. Your call.”

The one who came for him had obscured his face with a scarf and pulled his hood tight around his head. Petrovitch knew enough about him already to know he wasn’t a kid doing something stupid for the first time, but a really not-very-nice man who hurt people and made their lives a misery.

After the first missed swing and before the second milling arm could reach him, Petrovitch casually pushed out his left hand against the bigger man’s sternum. He used enough force to crack ribs, momentarily stop the heart and send the body hurtling to the far side of the road.

“You can go home if you want,” he said to the other two, then ignored them. He opened the door and got behind the wheel. “You okay, Newcomen?”

“How…?”

“This file on me the FBI gave you: what did it actually say?” The car’s engine whined, and they drove off. After a while, another car passed theirs, and he remembered to put the lights on.

“I can’t tell you. It’s classified.”

“Yeah, course it is, though to be honest, I think so little of it I haven’t bothered hacking it. But judging from your reaction, I’m guessing it didn’t mention either the automatic car thing, or that I’ve got extensive cybernetic replacements.” He turned off the infrared before looking directly at Newcomen. “I can do these things because I’m a yebani cyborg. Vrubatsa?”

Newcomen wasn’t confirming or denying whether he understood. He was busy trying to push himself backwards through the upholstery, intent on putting as much distance as possible between him and the aberration before him.

Petrovitch faced the windscreen again and watched the Metrozone glide by. “We’ve fallen right into Uncanny Valley there, haven’t we? Don’t worry, Newcomen. You’ll get used to me.”

Petrovitch put his shoulder to an anonymous door on Brixton High Street, and led the way up a set of bare wooden stairs. Cooking smells grew stronger the further he climbed – signature smells he recognised from earlier days when he was new in town.

“Hungry yet, Newcomen?”

“No, not really,” said the agent. He looked like he was already eating some particularly sour lemons. Particularly he wasn’t enjoying trying to squeeze his suitcase up the narrow staircase.

“I’ve ordered for both of us. It’s probably safer that way.” He got to the top of the stairs, where a massive slab of a man blocked entry to the dining room. Infoshades hid his oriental eyes, but the wireless earpiece was clearly visible: no hair at all on the man’s shaved, scarred head. “Wong’s expecting us,” said Petrovitch.

The bouncer sneered down at him, and on seeing Newcomen half-hidden behind his luggage, spat on the floor.

“Yeah, I get to choose the company I keep, not some neckless svinya.” Petrovitch flexed his fingers. “I could throw you down the stairs and the nerve impulses won’t have travelled to your walnut-sized brain by the time you hit the bottom. You can choose that, or get the huy out of the way.”

The man started chuckling to himself, and his great belly shuddered in waves. “You’re him.” He had a grin of black and silver teeth. “You’re Petrovitch all right. Go right in.”

“Thanks.” The door opened with a burst of noise and steam. “Mudak.”

A dozen tables were already full of diners, talking, laughing, shouting and singing. C-pop cranked tinnily through inadequate speakers in the ceiling, and the air was almost opaquely blue with burnt cooking oil.
