Quinn ducked under the tape at the bottom of the service stairs. Condensation beaded on the tiled walls of the old Camden platform, and the air carried damp brick, burnt sage, and a copper tang that sat on her tongue. Emergency lamps the Met had strung from the tunnel ribs threw hard white pools across a row of stalls that had no business existing on a line closed since the seventies. Canvas awnings sagged between iron pillars. Wooden crates stood open. Glass jars lined a trestle, their contents shifting even without a draught. A bone token the size of a shilling lay in a brass dish by the nearest stall, its surface scored with marks she did not recognise. She checked the worn leather watch on her left wrist. 03:47. The second hand swept past twelve. Her shoulders stayed square. A uniformed constable straightened from a crate of dried roots. “Detective Quinn. Body’s at the far end. Stall eighteen. SOCO’s waiting on you before they bag anything.” “Who found him?” “Anonymous call to the Camden desk. Female. Accent they couldn’t place. Said we’d want a look before the market packed up.” Quinn moved down the platform. Her boots found the old Northern Line tiles, cracked and slick. Stalls flickered past: a rack of knives with handles of yellowed horn, a cage of moths the size of a palm, a ledger bound in something that was not leather. She kept her hands at her sides. Stall eighteen sat under a patched green awning. A man lay on his back between the counter and a stack of crates, one arm flung toward a spilled tray of brass fittings. Grey at the temples. Wool coat still buttoned. No visible wound from ten feet out. A small brass compass rested in his open right palm, its casing mottled with verdigris, the face etched with sigils that caught the lamp light. Sergeant Hale crouched by an empty cash box, latex already on. He looked up as her shadow crossed the tiles. “Robbery. Cash gone. Phone gone. Watch gone off his left wrist—see the tan line. Looks like a smash and grab that went pear-shaped when the poor sod put up a fight.” Quinn stood over the body. The man’s eyes were open, filmed, fixed on the tunnel roof. No blood on the coat. No blood on the tiles beneath him. The compass needle trembled, then settled, pointing not north but at a blank stretch of brick behind the stall. “Where’s the blood, Hale?” “That’s the bit I don’t like. No spatter. No pooling. Pathologist’s on the way, but if this bloke fought, he did it without bleeding.” Hale rocked back on his heels. “Could’ve been poisoned. Could’ve been a heart. Could’ve been anything. Market like this, half these stalls are selling powders I wouldn’t put in a rat. My money’s still on a deal gone wrong. These people don’t call us. Someone wanted this one found.” Footsteps clicked on the tiles behind them. A woman in a navy coat stopped at the edge of the awning, round glasses catching the lamp, a worn leather satchel heavy against her hip. Curly red hair. Freckles across the bridge of her nose. She tucked a strand behind her left ear and kept her hands visible. “Detective Quinn? Eva Kowalski. British Museum. Restricted archives. Your superintendent rang my department an hour ago. Said you had markings that weren’t in the database.” Hale’s mouth tightened. “Civilians off the platform, miss. This is a crime scene.” “She’s cleared.” Quinn did not look away from the compass. “What do you see?” Eva stepped under the awning. She knelt without touching the body, satchel settling against her knee, and studied the sigils on the compass face. Green eyes moved from the needle to the brick wall it indicated, then to the bone token still sitting in its dish two stalls down. “This isn’t a robbery.” She adjusted her glasses with one knuckle. “The compass is a Veil piece. Shade work. It points at rifts, not north. It’s pointing at that wall because there’s a seam there, or there was. And the token at stall three is an entry mark. This market doesn’t let you in without one. Whoever killed him had a token or he let them through.” Hale snorted. “Or he got jumped by someone who nicked a token off a punter. Occult doesn’t pay the rent, Miss Kowalski. Empty till does.” “The till was empty when the market opened.” Eva’s voice stayed level. She opened the satchel, drew out a thin notebook, and flipped to a sketch of the same sigils. “I catalogued a piece like this last month. The artisan who made them works this circuit. Moves with the market every full moon. If this is him, he doesn’t keep cash in a box. He keeps it in a hollow under the third crate from the left.” Quinn crossed to the crates. She lifted the third from the left. A panel in the wood gave under her palm. Inside: a roll of notes bound with twine, untouched. She let the crate settle back. Hale stood. “So not a robbery. Poison, then. One of his own powders. Rival trader. We’ve got a whole tunnel of suspects who don’t exist on any electoral roll.” Quinn returned to the body. She crouched. The wool of the coat was dry. The man’s fingernails were clean, no trace of the powders from his own jars. The tan line on his left wrist was sharp, but the skin there was paler than a week’s absence of a watch would account for. She turned the wrist with two gloved fingers. A faint circular impression sat below the tan line, smaller than a watch face, ridged. “He wore something else under the watch.” Eva leaned in. The satchel strap creaked. “A second token. Some of the older traders stitch them to the skin. If it’s gone, whoever took it knew where to look.” “Or it was never stitched. Impression’s too shallow.” Quinn let the wrist rest. She studied the compass again. The needle held on the brick. Verdigris crusted the hinge, old, not staged. She opened the casing with a thumbnail. Inside, beneath the glass, a hairline crack ran across the face, and a flake of something dark had caught in the crack. Not rust. Not verdigris. She held it to the lamp. “Hale. Light.” He angled a torch. The flake was reddish-black, dry, smaller than a pinhead. It sat in the crack as if pressed there. “Blood?” Hale’s torch beam steadied. “From the fight you say didn’t happen?” “Wrong colour for fresh. And it’s under the glass. The case was shut when we got here.” Quinn closed it. The needle twitched toward the wall, then past it, toward Eva’s satchel, then back. “Miss Kowalski. Your books. Anything in them about a compass that tracks more than rifts?” Eva tucked hair behind her ear again. She pulled a cloth-bound volume from the satchel, pages marked with ribbon, and found a plate of an identical instrument. “Attuned to supernatural energy. Nearest rift or portal. That’s the standard function. Some of the Shade pieces were dual-keyed. If the owner dies holding it, the needle can hold the last living signature it registered. Not the killer. The last person the dead man touched.” Hale rubbed his jaw. “So we’re chasing a ghost signature. Brilliant. I’ll put that in the report.” Quinn stood. She walked the three paces to the brick wall the needle had favoured. The mortar was damp, same as the rest of the tunnel, but a section the width of a door showed a hairline where the pointing had been raked out and packed again, paler than the surrounding joints. She pressed. The brick did not give. No draught. No seam she could see. She turned back. The spilled tray of brass fittings lay where the dead man’s arm had thrown it. Among the hinges and clasps sat a single bone disc, same size as the token in the dish, but this one was snapped clean across. The break was new. No dirt in the fracture. “Hale. The anonymous call. Female. You said the accent couldn’t be placed.” “Desk sergeant’s notes. Not local. Not anything he recognised. Call lasted twelve seconds. She gave the station name and stall number and hung up.” “Stall number. She knew the layout.” Quinn picked up the broken disc with tweezers from her pocket and held it to the light. The scored marks on it matched the intact token, except one line that continued over the break, cut after the snap. “This was broken here. After he was down. Someone wanted it unusable.” Eva closed the book. “A voided token. Standard if you’re cutting someone out of the circuit. The market moves on the full moon. That’s three nights off. If they voided him, they didn’t want him following to the next site.” “Or they didn’t want us following.” Quinn set the disc on the counter. She looked at the man’s clean nails, the dry coat, the money still in the crate, the compass with its trapped flake, the packed mortar, the tan line and the smaller impression beneath it. Hale’s robbery sat on none of it. Eva’s voiding sat on some of it and missed the rest. She went back to the body. The compass needle had shifted again, a degree off the wall, toward the service stairs she had come down. She watched it. It held. The lamps hummed. Water ticked in a pipe overhead. Hale waited with his torch. Eva’s fingers rested on the satchel flap. Quinn lifted the dead man’s left hand a second time. The shallow circular impression on the wrist was not from a token. The ridges were too even, too mechanical. She knew that pattern. She wore a version of it. A watch. Not his missing one. A different case, pressed there hard enough and long enough to leave a mark after the first watch was already gone. Someone had held him down by the wrist. Someone who wore a timepiece on the left. She looked at her own leather strap, then at Hale’s bare wrists, then at Eva’s. Eva’s left wrist was bare. A pale band showed where a strap had sat until recently. Quinn’s gaze travelled from that band to the satchel, to the notebook with its sketch of the sigils, to the volume with the plate, to the way Eva had known the hollow in the third crate without looking. The compass needle held on the stairs. Quinn straightened. The platform stretched behind her, stalls and shadows and a market that was not supposed to be here. She kept her voice even. “Miss Kowalski. When the superintendent rang your department. What time was that.”
