The rain had beaten Camden into a dark metal sheet. Gutters ran full. Neon from a late chemist shop broke apart in the standing water and reassembled under Detective Harlow Quinn's boots each time she landed. Ahead, the suspect's charcoal coat cut between a shuttered record shop and a row of chained cafe chairs. He ran light on his feet, head down, one hand tucked to his ribs, fist closed on a shape that did not swing. Quinn took the corner on the outside line. A taxi threw a wall of spray off the kerb. It struck her from hip to shoulder, cold as a sluice. She shook it out of her eyes and kept the coat in view. Salt-and-pepper hair, cropped close, shed the water in a short fan. The leather watch on her left wrist knocked the cuff of her coat with each swing of her arm. "Police. Stop where you are." He hooked into an alley that smelled of wet cardboard and hot oil. "You left Silas' bar at nine. I've had you since the lock. Plant your feet." Crates toppled. Limes scattered, hard and bright under the security lamp. Quinn's boot found one and she rode the skid, knee bent, weight forward, the way a parade-ground instructor had demanded of her on worse ground than this. The lime shot away. She did not go down. "You're not built for this stair, Quinn." His voice came back off the brick, thin with breath. The sound of her name struck past the cold on her skin. She drove on. "Then stop and tell me how you know it." A chain gate. He hit it with his shoulder. The mesh belled and sprang. Quinn caught the frame with both hands and wrenched it past her body before it could bite shut on her hip. The alley kinked towards the canal, then towards a brick arch furred with buddleia, the kind of mouth the city left when it retired a station and hoped no one would notice the teeth. A man in a doorway lifted a phone. "Oi. He went for the old stair. Under the bridge." "Stay there. Don't follow." Quinn thumbed her radio. Rain ticked the grille. "Quinn to Control. Foot pursuit, west of the lock. Suspect is male, charcoal overcoat, heading for the disused entrance beneath the bridge. I want a car on the road and another on the towpath." The reply came in pieces. Engine noise. The weather chopped the desk sergeant's vowel into scraps. "Quinn... losing you. Repeat... do not enter any—" She lost the rest when the suspect dropped onto the stair and the brick took his shape out of the lamplight. The stair was slick with moss and pigeon grit. Quinn took it on the balls of her feet, one hand on the rail, torch in its loop. Below, the suspect stopped at a landing that should have ended in a bricked vent. His palm came up. A disc the colour of old bone caught the wet light. He pressed it to a slot cut into the mortar, a slot no Transport for London plan would admit. Stone answered stone. A seam opened in the wall with the grind of a heavy door on old iron. Heat rolled out. Incense. Hot copper. Orange peel scorched in a pan. Under all of it, the iron breath of a tunnel that no longer carried trains. He slid through. The seam began to forget it had opened. Quinn hit the landing and set her palm to the moving brick. Rain tracked the sharp line of her jaw. Lantern-light from the gap caught the brown of her eyes. Not the flat white of a platform beyond that gap. A market. Stalls. Hanging lamps. Voices trading prices in languages she could name and two she could not. The charcoal coat shrank between racks of maps whose coastlines refused every atlas on her desk. Her radio spat. "Control to Quinn. Hold the street. Do not go below ground. Confirm." A man stepped out of the shadow under the buddleia. Olive skin. Short curls gone dark with rain. Tomás Herrera, the Saint Christopher medallion stuck to the hollow of his throat. Sleeves shoved to the elbow. The scar along his left forearm showed pale against the wet. A canvas roll hung from his fist, the sort a paramedic kept when the work had to travel. "You don't want that door." Quinn kept her palm on the brick. The seam chewed another inch towards shut. "I watched you leave the Raven's Nest with a woman who couldn't keep her feet. Silas poured. You collected. Now you're on this stair. That's a pattern, Herrera." "She kept her feet when I was done. That's the job left to me." "Your licence says otherwise." "My licence is a piece of paper in a drawer in Seville and another drawer in London. The people down there don't survive on paper." He nodded at the gap. Lamplight put a warm edge on his brown eyes and left the rest of his face in rain. "The Market sits under Camden until the moon turns. Then the stair leads somewhere else, or nowhere. Your suspect paid the door with a bone token. You bring a badge. The door can tell the difference." Below the gap, glass broke. A vendor cursed. The charcoal coat shouldered between a stall of stoppered jars and a cage of moths with wings like torn paper. In one jar a dark liquid climbed the glass and drew a circle no hand had stirred. "Control. I'm at the bridge stair. Suspect is inside the lower market. I do not have a token. I'm going in after him." "Quinn, negative. Hold. Wait for—" She let the coil take the handset back against her chest. Tomás set two fingers on the medallion. "Morris told you to hold a stair. You held it. They brought you his coat." Her thumb found the worn leather of the watch strap and pressed until the buckle bit. She kept her eyes on the gap. "If I hand you my token, I can't get back to a man whose fever your hospital will rename until he's gone. Don't ask me for it." "I'm not taking your token." "Then hear the rest before that brick finishes its thought. No car follows you through. The stalls trade goods with no honest name and answers that don't belong in a statement. I stitch people on the pavement. I can't do it from the wrong side of a shut seam." The brick shivered under her hand. Another inch. The coat flashed at the end of a tiled aisle and slipped behind a curtain of dark beads. Quinn looked at the watch. Fog on the glass. The second hand marched. "Stay on the stair, Herrera. If I miss the twenty-minute check, you tell Control I went through of my own choice. You tell them the suspect used a bone token. You do not follow me." "Harlow." She put her shoulder to the seam and drove. The wall resisted, then gave a hand's width of heat and spice and old electrified air. Her torch came out of the loop. The beam cut a path between stalls hung with photographs. None of the faces matched a file she could swear to, though one frame carried the green wash of a Soho bar sign, the Raven's neon bled into paper. "Metropolitan Police. Stop." The charcoal coat broke into a run between the lamps. A stallholder yanked a tray of vials clear of her boots and jabbed a finger past the beads. "Left. Lower platform." A draught from the dead tunnel pushed clove smoke into her face. Tile took the place of moss under her soles. Quinn followed the shout and the hem of the coat between signal posts stripped of paint. The suspect's shoulder clipped a hanging map. The map spun. She went through the gap it left, torch beam fixed on the charcoal cloth.
