The grate on Kentish Town Road had been padlocked since before Quinn was born, and someone had cut it clean through. She ducked under the cordon tape and went down. The stairs swallowed the street noise by the second flight. Below, the work lights of the crime scene unit threw hard shadows across tiles the colour of old teeth, and the air carried wet brick, ozone, and something sweet underneath — a church after a wedding, frankincense gone stale. A uniform met her at the bottom, breath fogging. "British Transport Police want it, guv. Their station, technically." "Their station's been closed a hundred years. They can want." The dead man lay on his stomach along the platform edge, arms arranged at his sides, cheek pressed to the tile as though listening for a train. Good coat. Bespoke, if Quinn knew stitching, and she did. No labels. A woman crouched beyond the body — small, red hair twisted up and escaping, round glasses gone white with reflected lamplight, a leather satchel brimming with paper at her hip. "Who let a civilian past my tape?" "She's on the list." The uniform checked his board. "Consultant. The symbols." "Dr Kowalski." The woman didn't rise. A pencil hovered over her notebook. "British Museum. I work the restricted archive." "Quinn. Detective." She pulled on gloves and stepped to the body. "Talk to me about the symbols, Doctor. Then talk to me about why you got here before I did." "Your people rang the Museum at six. I rang a cab at six-oh-four." The pencil pointed, eraser-first, at the chalk marks ringing the corpse — interlocking figures, angular, nothing like the pentagrams teenagers sprayed on lock-ups. "These are binding marks. Pre-Christian, probably older than the city. Whoever wrote them believed they were keeping something from leaving." "Whoever wrote them wanted us to think so." Quinn crouched. "Look at his left arm. The line passes underneath the elbow. Unbroken." Kowalski leaned in. A freckled hand rose, tucked a curl behind her left ear. "Chalk on tile, chalk under body. He was laid down first. The ritual came second." Quinn stood. "Your occult killer staged his own occult. Keep going, though. I like a story with my evidence." "Staging a ritual is still a ritual." Kowalski closed her notebook. "London's folklore is full of gatherings that appear and vanish. Cheapside. Goblin markets. Every city tells it. A market where you buy what can't be bought." "Goblins didn't move this man." Quinn lifted the edge of the coat. Purple-black discoloration banded the corpse's shoulder blades, the backs of the arms. "Lividity's on his back. He died supine and stayed that way for hours. Somebody turned him over and delivered him here like a parcel. Patel — confirm for the record." The SOCO glanced up from his camera. "She's right. Post-mortem staining's posterior. He's been moved, guv." "Moved from where?" Kowalski asked. "That's the bit nobody's going to enjoy." Quinn walked the platform slowly, torch low. Decades of dust lay over everything, undisturbed — except a clean circle around the body, two metres across, and beyond it two thin scored lines. Heel marks. Drag marks. She traced them with the beam. They began two metres from the corpse and ran to the far wall. They started nowhere. No footprints fed into them. The dust on either side sat thick and grey and untouched, as if the dead man had been dragged out of the brick itself. "Guv." Patel had the victim's wrist turned to the light. "Watch is cracked but running. Second hand's going backwards." "Cheap movement." Quinn took the wrist herself. The crystal was starred, the hands fine gold, the case worth more than her car. The second hand swept anticlockwise, steady as a heartbeat. "Cheap movements don't come in eighteen carat," she said. "Bag it." The right fist was closed. She eased the fingers open — rigor fought her, then gave. Inside sat a small brass compass, its casing furred green with verdigris, the face etched with marks that matched the chalk on the tiles. The needle didn't point north. It pointed at the wall. Quinn lifted it on the end of a pen. The needle swung, settled, held on the bricked archway at the platform's end. She stepped left. The needle tracked her, then slid past her to the arch again. "Broken," Patel said. "Compasses don't break toward architecture." She lowered it into an evidence bag and the needle pressed flat against the plastic, straining for the wall like a dog on a lead. In the coat pockets: no wallet, no phone, no keys. A single disc of carved bone, holed through the centre, worn smooth as a river stone. Quinn held it up to Kowalski. "Georgian gaming counter." The curl went behind the ear again. "You're lying, Doctor." "I'm guessing. There's a difference." "There's a difference between guessing and going pale, too." Kowalski's mouth opened. Quinn was already moving, torch raking the floor at a shallow angle, and there it was — what the SOCOs' overhead lights had flattened into shadow. Four parallel gouges in the grime, repeated down the platform at intervals. Trestle legs. Dozens of them. Wax drips in colours no candle came in — green, black, a red too dark. Iron hooks screwed into the ceiling in rows, their threads bright where rust should have been. And the smell, stronger here: frankincense, copper, crushed herbs. She pulled a dead enamel lamp from its bracket and found a scrap of paper folded inside the shade. Unfolded it against her palm. "Two years," she read. "One name. Six teeth. A voice, unbroken." She looked up. "It's a price list." The platform went quiet. Even Patel's camera stopped. "This wasn't a murder scene," Quinn said. "It was a market. Stalls along here, goods on hooks, chalk circle for the — for whatever the circle was for. It ran last night, it cleared out in hours, and they left him behind." She glanced at the body. "A message. Or the change from a transaction." "That's—" Kowalski stopped. Freckles stood out against milk. "Detective, if I told you what a market like that would mean, you'd have me removed." "Try me." "I'd rather show you. Somewhere with fewer cameras." Quinn held her gaze a long moment, then walked to the bricked arch. Up close, the mortar lines weren't uniform. Along one edge, the pointing was fresh — pale, damp, weeks old at most. The arch wasn't bricked up. It was a door, and someone had disguised it as a wall. On the iron hinge at its base, scraped clean of a century's rust, sat a single fingerprint in verdigris green. She took out her notebook and unfolded the photocopy she kept inside the cover, the paper gone soft from three years of her pocket. A chalk mark, photographed at another scene, in another part of the city, on the night DS Morris died and nobody could tell her how. She held it beside the nearest symbol on the tile. The same hand. The same mark. "Dr Kowalski." Quinn folded the copy away and checked her watch — Morris's watch, the leather strap cracked dark at the buckle. "You're going to tell me what that token buys. Patel, photograph the hinge, then get me a warrant for the wall." "A warrant, guv?" "Whatever sold here paid in bone." The compass needle lay flat against the bag in her palm, pointing through the brick. "I want it opened before the moon's full."
