The tape across the service entrance read POLICE — KEEP OUT in three languages, and in a fourth, scrawled in marker: REALLY. Quinn ducked under it and took the stairs into the dark under Camden. Forty-one steps down, the twenty-first century gave out. Green and cream tiles wept along the arches, and a generator thudded somewhere behind her, feeding work lamps strung the length of a platform no train had served in living memory. The dead man lay at its centre, pale against the black floor, and the smell reached her before the body did — struck matches and something sweet underneath, burnt sugar with a wire of ozone in it. DS Okafor waited at the bottom of the stairs, gum working, notebook already open. "Boss. Martin Hale, thirty-four, known face, no fixed address. Survey crew for the new extension tripped over him at three this morning." "Cause of death." "Doc's provisional is cardiac arrest secondary to burns. Working theory is he cooked up, the cooker flashed, caught his shirt, and that was that. Scavengers stripped his kit before the crew arrived — no foil, no spoons, nothing." Quinn's thumb found the worn strap of her watch. 4:47. She gave the platform a long look before she gave the dead man one. Dust lay over everything, thick as felt — except for a clean oval, six feet by three, dead centre, with Hale lying in the middle of it. "Who swept the floor?" "Nobody swept—" "Someone did. Then he lay down in the middle of it and burned without a cooker, without matches, without scorching a single tile nine inches from his shirt." She crouched, gloved, lifted the hem. The burn spiralled out from his sternum, flesh charred to the ribs — and the outer face of the cotton above it sat pristine, a band logo still crisp on the chest. She turned the collar. Singed on the underside. Clean on top. "Flash fires do strange things." "Flash fires leave soot. There's none on him, none on the tiles, no accelerant, no wick, no tin." She sat back on her heels. "The fire climbed out of him, Okafor. Not onto him." Okafor's gum stopped. He wrote nothing. She rose and walked the platform edge. A line of salt, poured in one pass, ran six feet along the lip, half of it clumped where the damp had got at it. At the far end of the platform, a woman crouched at the wall with a torch between her teeth — small, round glasses fogged, red curls crushed under a hood, a leather satchel sagging with books. Chalk marks covered the tiles around her, spirals and bars, the same geometry as the burn on the dead man's chest. "The Museum sent her," Okafor said, following her look. "Kowalski. Restricted collections. We ring them about marks like these, they ring her. I'd take it as an insult to common sense if the marks weren't so strange." Quinn crossed to her. "You chalked nothing here yourself?" "Cross my heart." The woman stood, wiping her glasses on her sleeve. "These are wards. Door grammar — the kind you use to hold one side of a threshold shut. Right-handed, pressed hard, cheap chalk. Your man did this himself, and he did it in a hurry." "You've seen this hand before?" "I've seen the grammar before." She tucked a curl behind her left ear. "Not the hand." Quinn held her gaze a beat longer than politeness allowed, then turned back down the platform. "Show me his pockets." "Stripped," Okafor said. "Except—" He nodded at the tarp where the techs had laid out what little they'd found. A stub of tailor's chalk. A gold wedding band, separate. And a brass compass the size of a matchbox, green with age, wrapped in a sock. "Stripped," Quinn said, "but the ring came off his finger and got left behind. Thieves who miss gold don't miss gold." "Fingers swell." "Fingers swell. Socks don't unwrap themselves." She picked up the compass. Verdigris sat in the engraving like moss in brickwork, and around the face ran a ring of sigils — the same spirals, the same bars, chalked sixty feet away on the wall. The needle wasn't pointing north. It turned in a slow corkscrew, wobbled, and lay flat, aimed down the platform at the bricked-in arch of the north tunnel. "Voodoo tat," Okafor said. "Stall junk." The tech popped the dead man's right fist with a spatula, and something small and white rolled into the evidence tray. Bone, polished smooth, a spiral carved into it. "That's not tat." The researcher had come up quietly behind them, satchel hugged to her chest. "That's a ticket. Bone token, price-mark spiral. You don't buy one off a stall. You buy one to get into the market at all." "Which market?" She glanced at Okafor, at the tape, at the survey crew's boots at the top of the stairs. Her voice dropped. "The one that met on this platform until the moon turned Wednesday night. Then it packed and moved. It always moves. You'd need a token to have seen it, and he had one." "A market," Okafor said. "Under Camden. Right." "You'd need a token, Detective Sergeant. He had one." Quinn turned the compass in her hand. "How do you know what it sells?" The woman tucked the same curl behind her ear again. "I read." "How long since death?" "Doc says two nights minimum. Thursday, small hours." Okafor flipped his notebook closed. "Which fits a Thursday overdose." "It fits nothing." Quinn started walking, arm out, compass level. The needle dragged, swung, steadied — not at the body, not at the salt, but at the bricked arch, and it stayed there like a dog at a door. "The market left Wednesday. Hale came back Thursday to an empty station. Chalked his wards, poured his salt line, stood in the middle of the platform with a finder in his pocket, and asked a tunnel that's been bricked up since before the war to open." "Boss—" "Look at the floor." She pointed with the compass. "Every bootprint on this platform belongs to the survey crew, and it stops at the stairs. No prints to the body. No drag marks. And the dust — it's not swept, it's scoured. Pulled toward the middle, same as the air was." She nodded at the far wall, where a grey ribbon of dust drifted along the skirting toward the arch, against the draught, like the room was breathing in. "He didn't walk onto this platform. He arrived on it. The fire didn't come at him. It came through him. Whatever opened on the other side of that door didn't ask him for his token." Okafor looked at the arch, then at her, then at the arch again. "You're saying a wall killed him." "I'm saying a door did, and it hasn't closed." She pressed her bare palm flat to the mortar. Warm. Flask-of-tea warm, in a tunnel that hadn't seen a sunbeam in eighty years. She took her hand back and wiped it on her coat. The researcher had gone very still, glasses pushed up into her curls. "You've felt that before. At another scene." "Once." "Boss." Okafor held out an evidence bag, flat. "The compass goes in the bag. All of it does. This is a crime scene, not a ghost hunt." Quinn wrapped the compass back in its sock and slid it into her coat pocket. "Bag the rest. Nobody files this as an overdose. Nobody drills that wall, leans on it, or takes so much as a photograph of it with a personal phone. And a uniform stands exactly where I'm standing until I say otherwise." "The compass is evidence, Detective." "It's not evidence. It's a pointer." She looked at the arch, where the needle lay flat against the face, patient as a clock. "And it's still pointing."
