The hatch was in the pavement outside a shuttered kebab shop on Ferdinand Street, and it smelled like a mouth. Detective Harlow Quinn went down the ladder with her torch clamped between her teeth, counting rungs out of habit. Thirty-one. At the bottom the air changed — not colder, exactly, but older, the way air gets when nothing has breathed it for eighty years. Her boots came down on grit and something that crackled like sugar. "Ma'am." DS Owen Pryce was waiting at the foot of the ladder with his own torch pointed courteously at the floor and his tie tucked into his shirt like a man who'd read a leaflet about crime scenes. "It's about two hundred metres along. Watch the left-hand side, the drainage grates are gone." "Who called it in?" "Urban explorers. Kids, basically. Three of them, sixth-formers, they came down the same way we did looking for the old wartime posters. One of them's still being sick in the back of a response car." He fell in beside her, matching her stride with a small effort. "It's a disused stretch. Never opened to the public, apparently. Built in '38, shelter in the war, sealed in '52." Quinn said nothing and let her torch do the walking. The tunnel walls were tiled in cream and oxblood, the grout black with a century of coal dust and diesel and human skin. Every twenty feet a poster survived under peeling shellac: a woman in a headscarf holding a finger to her lips. HE'S IN THE ARMY NOW. The ticket hall opened out ahead like the inside of a lung. Two arched exits, one bricked up. A wooden booth with the glass gone. And a staircase — a proper old spiral, iron, with a cage of rust around it — coming down out of the ceiling and ending eight feet above the floor, cut off where the surface works had removed everything above. The body lay at the base of the staircase. Pryce's crime scene officers had rigged two work lamps, and the light they threw was surgical and cruel. Male. Fifties, maybe late forties. Grey overcoat, good wool, worn at the cuffs. Bald crown, the last of his hair in a grey fringe over one ear. He lay on his back with his left arm folded under him and his right hand open, palm up, fingers curled loosely, as though he'd been holding something and had let it go without minding much. The pool of blood under his head had dried to the colour and texture of treacle toffee. "So," Pryce said, and Quinn heard the little intake of breath that meant he'd been rehearsing. "My read is he came down the stairs. There's a section of the cage there, third landing up, where the bolts have gone — you can see the daylight gap from underneath if you get the angle. Rough sleepers use these places. Or he was one of the explorer types himself, older breed, they get obsessive. He misjudges the drop, comes off the end of the staircase, back of the skull on that flagstone." He indicated a corner of stone standing a half-inch proud of its neighbours, a dark smear along the lip of it. "Blunt force, consistent. No defensive injuries. Nothing in his pockets worth killing him for. Toxicology'll come back with something, they usually do down here. Sad, but simple." "Mm," Quinn said. She crouched. Her knees complained; forty-one was doing that now. She set her torch on the ground so the beam raked low and flat across the flagstones, the way you did when you wanted to make the floor confess. Dust. Eighty years of it, fine as talc, undisturbed except where the response officers had trampled a path in from the tunnel and where the paramedics had knelt. She could read those tracks like a paragraph. Boot, boot, boot, knee, knee. And around the body, in a rough circle three feet out from the head— Nothing. "Pryce. Come here. Get low." He crouched. To his credit, he did it without arguing. "Tell me what's missing." He looked for a long moment. "Footprints," he said at last. "There's — hang on. There's no footprints coming from the stairs." "There's no footprints coming from anywhere." Quinn moved her torch a fraction, and the low light picked out the surface of the dust: a plain, level, unbroken grey field, running from the base of the staircase to the bricked-up arch on the far wall. "He didn't walk here. Nobody carried him here. And he didn't fall from that staircase either, because a man who drops eight feet onto stone kicks up dust like a bomb going off. There'd be a crater. There'd be a halo. Look at his coat." Pryce looked. The wool was clean. Not spotless — old stains, a scuff at the elbow — but the nap of it lay flat and grey-free, and the soles of the dead man's shoes, tilted toward them, were dark and slick and clean as a wet road. "His shoes are damp," Pryce said slowly. "His shoes are wet. There is no standing water in this hall. I checked the grates coming in, they're bone dry, and it hasn't rained in London for nine days." She lifted her torch, moved it up. "And look at the flagstone you like so much." The smear on the stone's edge was there, right enough. But she put her light on it side-on and the blood showed as a thin film feathering upward along the corner, in delicate fingers, against gravity. "That's not impact spatter," she said. "That's contact transfer. Somebody pressed his head against that stone, and pressed it the wrong way up." Pryce was quiet. She stood, joints clicking, and walked the perimeter. Two hundred and forty degrees of the ticket hall was ordinary ruin. The last hundred and twenty was not. The bricked arch had a shadow on it. Not a shadow — a stain, an outline, sooty and precise, describing a doorway within the arch: two uprights, a lintel, a threshold, all of them charred into the brickwork as though a door had been there and had burned, and the brick behind had cooled around the memory of it. Quinn put her bare palm flat against the centre of the outline. The brick was cold enough to hurt. And along the base of it, on the flagstones, a rime of frost lay in a neat crescent, already sweating at the edges. In a sealed tunnel in September. Frost. Her stomach did something small and familiar and unwelcome. Three years ago, a lock-up in Peckham, and DS Morris on the floor with his eyes open and no wound on him anywhere, and frost on the concrete in a shape like a doorstep. She had written *condensation, refrigeration unit* in her notebook because there had been no other words available to her, and she had gone on writing versions of that sentence for three years. "Ma'am?" Pryce, at her shoulder. "You all right?" "Get me gloves." He fetched them. She went back to the body and eased the dead man's overcoat open. Inside pocket: empty. Trouser pockets: empty, both of them turned. No wallet, no keys, no phone. Someone had gone through him with method. But the coat had a fourth pocket, a small welt sewn inside the lining under the left arm, the kind a tailor puts in for a pocket watch or a hip flask, and whoever had emptied him had been in a hurry, and hadn't known to look. Quinn's fingers found brass. She drew it out into the light: a compass, no bigger than a communion wafer, its casing crusted with a green-blue bloom of verdigris. The face was scratched all over with markings that were not letters and were not degrees. Under the glass, the needle swung, hunted, hesitated— —and settled, hard, pointing at the burned outline on the bricked-up wall. Quinn turned slowly on the spot, a full circle, watching it. The needle never once looked north. "That'll be a — souvenir, won't it," Pryce said. "Antiques market's just up the road." "Yes," Quinn said. "That'll be it." She palmed it into her jacket pocket, and felt the cold of it settle against her ribs, and looked at the dead man's open right hand, and at the small carved disc of yellowed bone lying six inches from his fingertips where he had let it fall. "Get the photographer over here," she said. "Every stone. And Pryce — nobody touches that wall."
