The sole of Quinn’s right shoe skidded on Camden High Street. She caught a shop shutter, took the impact through her palm and kept Marr’s grey coat in sight. He had twenty metres on her, a canvas satchel clamped under one arm and no concern for the traffic he forced to brake. Rain had turned the road into a smear of brake lights. Water ran from Quinn’s cropped salt-and-pepper hair and gathered beneath her collar. She lowered her shoulders and ran. “Police! Out of the road!” A man filming from beneath a shop awning lifted his phone higher. Quinn put a hand on the lens as she passed and shoved it down. Marr dodged between two buses. A black cab struck its horn and slid towards the kerb. Quinn slapped its bonnet, crossed in front of it and caught the sulphurous stink of wet brakes through the open window. Four hours earlier, she had watched Marr leave the Raven’s Nest beneath its green neon sign. Her source had placed him in the room behind the bookshelf, the room that appeared on no licensing plan. He had entered empty-handed and emerged with the satchel. Six minutes with the clique had given him a shape to carry and a reason to look over his shoulder. He had made her at Camden Lock. He had walked one circuit of the food stalls to confirm it, bought nothing, then run. Marr hooked an arm around a stack of delivery crates and dragged them into her path. Quinn planted one foot on the bottom crate, vaulted as the stack folded and landed in a stream of packaging foam. Something burst beneath her heel. She kept moving. She pulled her radio from inside her coat. “Control, Detective Quinn. Foot pursuit, male suspect, south from Camden High Street. Grey coat, canvas satchel. He’s armed.” Static worried at the speaker. “Say again, Quinn. Your location’s breaking up.” Marr turned into an alley between a shuttered pharmacy and a chicken shop. Quinn followed him into the smell of grease and rain-filled cardboard. “Units to the service roads behind the high street. I need a containment, not a convoy.” “Units are two minutes out.” Marr glanced back. She had gained three metres. He kicked a wheelie bin at her shins. Quinn twisted past it, clipped the wall and lost the ground she had made up. Beyond the alley, a hoarding carried a demolition notice softened by old rain. Marr ducked through a gap where the plywood had been prised away. Quinn went through after him. An abandoned station entrance sat behind the hoarding, its tiled front squeezed between newer buildings. The old roundel had been painted black. A torn shutter exposed a stairwell descending below street level, and the handrail shone where countless palms had polished away the rust. Her intelligence file had given this place three lines and a warning. The Veil Market. Entry by token. A location that changed with every full moon. The rest had consisted of statements from people her superintendent no longer considered reliable. Marr took the stairs two at a time. Quinn caught the satchel strap on the sixth step and hauled him backwards. He struck the tiles with one shoulder. She trapped his arm, reached for her cuffs and saw the knife come out of his sleeve. The blade opened her coat from elbow to wrist. Cold air touched her skin before the blood did. She seized his knife wrist and drove it against the wall. “You’re under arrest.” “For running?” “We’ll start with the knife.” Marr slammed his forehead into her cheek. Light jumped across Quinn’s vision. Her grip loosened. He slashed through the satchel strap, tore himself free and stumbled down the remaining steps. A white disc on a black cord dropped from his ripped coat pocket and bounced off the tiles. Marr did not stop for it. Quinn scooped it up as she passed. Bone, not ivory. A groove had been cut through its centre and filled with something black. The cord was still warm from his pocket. At the bottom, an iron door blocked the passage. Marr pressed a second disc into a brass slot. A shutter snapped open behind it, and an eye examined him through the gap. “Business?” “Buying.” The door opened on warm air and the murmur of a crowd. Marr looked back at Quinn. Blood ran along her wrist and dripped from her fingertips. “Your badge won’t open this.” “Neither will a satchel full of stolen names.” “It’s not names I’m selling.” He slipped through. The door closed behind him. Quinn reached it before the echo of his footsteps died. She struck the iron with the heel of her hand. “Metropolitan Police. Open the door.” The shutter moved aside. The eye reappeared, pale and heavily lidded. “Token.” She held her warrant card to the gap. “That man assaulted a police officer.” “Then don’t buy from him.” “There are units on their way. You can open this door or explain an obstruction charge from the back of a van.” The eye dropped to her card, then rose to her face. “Not currency.” The shutter closed. Quinn keyed her radio. “Control, Quinn. Suspect has entered a structure below the disused station entrance. I need units behind the hoarding, service alley off—” The speaker produced a long, empty hiss. She tried again and gave the full location. No answer came. Her phone had one bar when she pulled it out; by the time she opened a message to her sergeant, the bar had gone. Rain hissed on the steps above her. Beyond the iron door came a restrained percussion, too even for footsteps, and a woman laughing close to the other side. Quinn climbed two stairs towards the street. Her training offered a clean sequence. Hold the entrance. Preserve the token. Wait for uniform. Seal both ends of the alley and obtain a warrant for premises whose ownership would occupy someone in legal services for a week. She looked at her worn leather watch. The second hand crossed twelve. Marr had been inside for forty-eight seconds. In fifty more, the satchel could pass to another buyer. In two minutes, he could leave through an exit that did not appear on any plan. The file said the Market moved at the full moon. Tonight was the last reliable intelligence they had. Her thumb found the groove in the bone disc. Three years ago, DS Morris had gone through a service door while Quinn held a stairwell and waited for instructions. They had found him in a dry room with water in his lungs. At the inquest, she had answered every question with the precision expected of her and supplied nothing that explained the wet footprints stopping beside his body. She descended the two steps. The cut on her arm had started to throb. She folded her coat sleeve over it, pressed the cloth hard against the skin and knocked again. The eye returned. Quinn opened her palm. “One entry?” “If it’s valid.” “And if it isn’t?” “You get to keep it.” A brass tray slid out beneath the slot. She laid the disc on it. The tray withdrew. Something clicked behind the door, followed by a wet crunch. The gatekeeper gave a small grunt. “First visit?” “That obvious?” “You’re still standing like you expect a camera.” Quinn lowered her hand from the place where her warrant card usually sat. “Rules?” “No blood on the tiles. No handling stock without an invitation. No drawn weapons.” “I’m bleeding.” “Then mind the tiles.” The iron door opened. Quinn stepped through. A narrow stair carried her down between tiled walls. Old adverts had been scraped away, leaving pale rectangles and fragments of smiling faces. With each step, the rain lost definition. By the final turn, she could hear only the Market: coins on glass, low bargaining, a violin being tuned, something knocking from inside a closed box. The passage opened onto a disused Tube platform. Stalls covered the platform and continued along the track bed, their roofs stitched from tarpaulin, velvet and sections of police incident tape. Lamps hung from the old electrical cables. Their bulbs burned white, amber and a chemical green that stained the tiles beneath them. Quinn stopped at the edge and counted exits. The passage behind her. A service staircase choked with merchandise. Two tunnel mouths, one curtained, the other open. On her left, a vendor weighed red crystals on a set of brass scales. Each measurement made the flame above his burner bend away from the pan. Across the tracks, keys turned themselves inside a glass case while a customer read their teeth through a magnifying lens. A woman in a post office uniform sold envelopes from a suitcase, naming no prices until her buyers whispered into her ear. Quinn put her phone away. No service. No photograph would focus on the vendor with the scales; the screen showed only a bright smear where his hands should have been. She wiped her bleeding fingers on the inside of her coat and moved into the crowd. People gave her room without appearing to notice her. A man with mirrors sewn into his lapels stepped aside. Two teenagers sharing a paper cone of blue powder stopped talking until she passed. Quinn kept her gaze on coats, satchels and hands. Tomás Herrera worked beneath a surgical lamp at the far end of the platform. A St Christopher medallion hung against his shirt, swinging as he leaned over his patient. His short dark curls were damp with sweat. The scar along his left forearm disappeared beneath a rolled sleeve and emerged again near his wrist, white against his olive skin. His patient lay across a camp bed with a wound below the ribs. Black threads moved under the skin around it. Herrera held a clamp in one hand and a curved needle in the other. “Herrera.” “You’re standing in my light.” Quinn shifted one pace. “Marr. Grey coat. Canvas satchel, cut strap.” “Does he need treatment?” “He needs a cell.” “Then you’ve both had a disappointing night.” The black threads around the wound drew tight. Herrera adjusted the clamp without looking at her. “I can come back with a warrant for every stall on this platform.” “You can come back with an orchestra. Keep your voice down.” His patient’s eyes opened. The pupils had narrowed to vertical cuts. Quinn looked away first. She scanned the track side and found a flash of grey beside the open tunnel. Herrera’s needle paused. “If I point, will you stop blocking my lamp?” “Yes.” He lifted his chin towards the tracks. “He went through the chemists’ row. Keep your badge covered. You’ll empty my clinic.” Quinn was already moving. She passed bottles bearing broken prohibition seals, a table of passports whose photographs changed when tilted, and a man selling revolvers wrapped in altar cloth. At the platform edge, she saw Marr push a fold of banknotes into a vendor’s hand. The satchel was gone. In its place he carried a narrow metal case. Marr glanced back and saw her. He vaulted onto the track bed, scattering gravel, and ran for the open tunnel. Quinn jumped down after him. Her shoes struck beside the rail. She found her footing and ran.
