He caught the battery wire with his fingertip. It bit him and he jerked away, growling. He reached farther up and took hold of the insulated part.

“Out of gear?” she asked.

He nodded, and she reached across the passenger seat to waggle the gear stick. He used touch to guide the wires together, flashes of blue worrying at his skin.

The engine coughed. He moved the wire back and forward and finally found the right point. The car wound itself into life again.

“Desperation plus East European engineering equals result,” he crowed. “Not pretty, but it works.”

“We’re still not going to make it in time, are we?” She clambered over the bonnet, and put her hand under Petrovitch’s shoulder to help him up.

“Not that one. Broken.”

“Sorry.” She swapped her grip to the other side. “But we’re taking too long. They must be at the tower by now.”

Petrovitch shook himself out. “You’d be forgiven for thinking so. But since the Jihad’s monsters are still crashing around, I can only conclude that Chain either hasn’t access to the secret room yet, or that it’s less use than he thought it was. Which means, we still have some wiggle room.”

“Get in the car and shut up, Sam.”

“Yes, babochka.”

She drove slowly down the road, moving this way and that to avoid the larger obstacles, rolling over the smaller ones. There were signs of the Jihad everywhere: gaps in the architecture where there ought to be none, straight furrows plowed across the fabric of the city, marked by fluttering yellow flames.

There seemed no reason for the pattern—one building left, another destroyed—but Petrovitch rather fancied that, come daybreak, a passing satellite might notice the similarity between the new face of the London Metrozone and the Tokyo rail network.

It hadn’t occurred to him that there might be people buried beneath the drifts of rubble, and that some of them might still be alive, until he saw a man bent over one of the mounds of rubble, picking at it piece by piece.

They rolled past, Petrovitch transfixed by the man’s lonely labor. He never looked up, just went on flinging bricks behind him one after another, digging down.

“Are you Okay?” Madeleine asked.

“I’m getting worried, that’s all.” He gnawed at the back of his hand. “You. Me. Especially me. We’re the weak link in the chain. If we get killed trying to stop the Jihad, no one else knows what’s going on. If there was a way of getting a message to Marchenkho…”

The Skoda scraped its already battered side against an abandoned fridge, lying in the street. There was more debris; boxes, clothes, shop fittings, loose packaging. Madeleine slowed to a crawl and peered out through the hole where the windscreen used to be.

“Don’t these things normally come with lights?”
