The stairs down to the old Camden passage had been sealed since before Quinn made detective, and the padlock on the grille still wore its rust like a scab. Somebody had cut the chain with bolt croppers and left the links curled on the concrete like shed skins. Quinn ducked under the blue-and-white tape and felt the temperature drop with every step, though July pressed hot against the city above. "Watch your head, ma'am. Cable's down on the left." The constable at the bottom held his torch low. Beyond him the platform stretched into darkness, tiles the colour of old teeth, posters for films nobody remembered peeling off the walls in long tongues. A knot of scene-of-crime officers worked at the far end, their lamps throwing hard shadows against the tunnel mouth. DS Ferreira met her halfway, notebook already open, tie loosened. He had that look he wore when he'd solved something before breakfast and wanted credit for it. "White male, mid-thirties, no identification. Found by a graffiti crew around four this morning — they did a runner, but one of them had a conscience and phoned it in from a call box, if you can believe it. Best guess: drug deal gone wrong. Place has been a squat on and off for years." "Best guess," Quinn said. She crouched beside the body. The man lay on his back between the platform edge and the tiled wall, arms arranged at his sides, legs straight. Too straight. His face held an expression she'd seen once before and had spent three years trying to forget — eyes wide, mouth open, the whole architecture of terror frozen mid-scream. Morris had worn that face. She pressed the thought down where it belonged. "Frost on his collar," she said. "July." "Fridges," Ferreira said. "Some of these old stations had cooling plant. Could be a pocket of cold air. SOCO's noted it." "There's no cooling plant in this station. It was a lift shaft station, lifts long gone." She moved her torch over the dead man's hands. No defensive wounds. Fingernails clean — no, not clean. Something grey under them, like ash. "Time of death?" "Doc says sometime between midnight and two. Though he keeps muttering about the core temperature being all wrong. Body's colder than it should be. Wants to run it again at the mortuary." Quinn stood and walked the scene in a slow circle, the way Morris had taught her — body first, then the space around it, then the space around that. Her leather watch ticked against her wrist. The platform dust lay thick and undisturbed, a grey felt over everything, except for a clean corridor where the graffiti crew had walked and where the body lay. No drag marks. No scuffle. No footprints approaching from the tunnel. "How did he get here?" she asked. "Same way the vandals did. Grille was cut." "The dust on the stairs is unbroken. I checked on the way down. One set of prints going up — the crew leaving. Nothing coming down. Nobody's used that entrance in weeks." Ferreira frowned into his notebook as if it had betrayed him. "Tunnel, then. Walked up the line from the running station." "In a three-piece suit?" She turned the torch on the dead man's clothes. Good wool, bespoke cut, handmade shoes with leather soles. Leather soles, on a man supposedly picking his way down a live rail tunnel in the dark. "And look at his shoes. Not a scuff. Not a fleck of track grease." "So he was carried. Dumped." "By ghosts?" She swept the beam across the floor. "One exit trail, no entry trail. The body appeared here, Danny. That's the problem you should be chewing on." She went back to the corpse and worked through his pockets with gloved hands. Wallet gone — Ferreira raised an eyebrow at that, mugging written all over his face — but the left breast pocket held something wrapped in a square of black cloth. Quinn unfolded it on her palm. A compass. Small, brass, green with verdigris, its face etched with marks that made her eyes slide sideways if she looked at them too long. The needle didn't point north. It trembled, then swung, and held steady toward the tiled wall behind the body. "Broken," Ferreira said. "Junk. Probably nicked it off a market stall." "There's a battery of these in a cabinet at the Museum." The voice came from the shadows beyond the lamps, and every head turned. A young woman sat on a crate by the wall, red curls escaping a clip, round glasses catching the light, a worn leather satchel clutched on her lap. A uniformed officer stood over her looking apologetic. "Sorry. I wasn't supposed to say anything. But it isn't junk, and it isn't broken." "Who is this?" Quinn asked the constable. "Found her on the platform when we arrived, ma'am. Says she's a researcher. She's been sitting quiet as you like, hasn't touched anything." "Eva Kowalski," the woman said. She tucked a curl behind her left ear. "British Museum, restricted archives. I study... older systems of navigation, among other things. That compass was made to point at something specific. Not north. If the needle's holding on that wall, then there's something in that wall it's pointing at." Ferreira laughed once, without humour. "Right. And I suppose the victim was navigating to Narnia when he overdosed." "Show me a needle mark," the woman said. "Show me paraphernalia. There isn't any. You're building a drug deal because it's the shape you recognise." Quinn watched her for a long moment. The girl's hands shook on the satchel strap, but her voice didn't. People who shook and still spoke were worth listening to. "You said there's a battery of these in a cabinet," Quinn said. "Meaning you've seen them before. Meaning you knew what this place was before we arrived." Eva's throat moved. "I knew what it used to be." "Which was?" "A market. It moves. It isn't here any more — not properly. But the door it used is still in the wall, and doors like that don't always close all the way." She nodded at the corpse. "He came through it. That's why there are no footprints. That's why he's cold. Wherever he came from, it's cold." Ferreira shut his notebook with a snap. "Ma'am, with respect—" "Get photographs of the wall," Quinn said. "Every tile. Full spectrum." She crossed to the tiles and ran her light across them. Advertising hoarding, blank cream glaze, grime. Then the beam caught something — a seam where no seam should be, a hairline of darker dark running in an arch from floor to apex, eight feet tall. She put her palm flat against the tile inside the arch and felt it through the latex. Cold. A deep, patient cold, like a river moving on the far side. In the dust at the arch's base lay a scatter of small white objects. She crouched. Bones — finger bones, bird bones, she couldn't tell — each one drilled through and strung on a thread of red that had rotted or been cut. Tokens of some kind. Dozens of them, dropped, scattered, trampled. "Payment," Eva said from behind her, quiet now. "You don't get through a door like that for free. He came through with a pocketful and dropped them when—" She stopped. "When whatever frightened him to death got close enough," Quinn finished. The doctor said fright, later, leaning over the body for the second time with his thermometer and his deepening frown. Massive cardiac event, no underlying disease, adrenaline off the scale, core temperature that made no sense at all. He said the word "anomalous" four times and looked at Quinn the way Morris used to look at her, right at the end, when he'd started keeping a second notebook he wouldn't let her read. Ferreira stood apart, rewriting his theory out loud to anyone who'd take it. Laced drugs. A hallucinogen. A prank that killed a man. The words got thinner each time he said them. Quinn closed her hand around the compass. The needle hadn't wavered from the wall in twenty minutes. Behind her the forensic lights hummed, the cameras flashed, and the hairline arch in the tiles held its patient cold against the warm London night. "Log the bone pieces separately," she said. "And I want Ms Kowalski's statement taken at the Yard. Full statement. Everything she knows about this market." "You're not seriously—" Ferreira started. "I'm seriously noting that your drug deal has no drugs, no entry, no exit, and a compass that disagrees with every other compass in London." She held his gaze until he looked away first. "Write down what you can prove, Danny. I'll handle what I can see."
