The man came out of the Raven’s Nest with blood on his cuff and a white disc clenched in his fist. Detective Harlow Quinn pushed away from the wall opposite the bar. Rain had soaked through the shoulders of her coat. Above the entrance, green neon turned every puddle the colour of old glass. “Herrera.” Tomás Herrera stopped. For half a second he looked straight at her, and she saw that the blood was fresh. Then he ran. Quinn crossed the road behind a taxi, close enough to feel its tyres throw water across her shins. Herrera cut left into the stream of late-night drinkers on Wardour Street. He was fast, but he kept his right hand pressed to his jacket pocket. Whatever he’d taken out of the Nest mattered more to him than balance. “Police. Stop!” A woman stepped aside. Herrera slipped past her and disappeared around the corner. Quinn followed, boots striking wet pavement. Eighteen years on the job had taught her not to sprint blind after a man who knew where he was going. She took the corner wide, checked his hands, checked the alley mouth beyond him. No weapon she could see. He vaulted a low chain at the far end of the lane. Quinn went around the post without slowing. Her radio crackled against her shoulder. “Control, this is Quinn. In foot pursuit of Tomás Herrera, heading north from the Raven’s Nest. Blood on his clothing. Request units to—” Static swallowed her. She tried again. The transmission light blinked red, then went dark. Ahead, Herrera looked back. His short curls were plastered to his forehead. Even from twenty yards, Quinn could see the fear in his face. That bothered her more than the running. For six weeks she’d watched people go in and out of the Nest. Herrera had been among the regulars: a former paramedic with no licence, a talent for arriving shortly before injured people vanished from hospital records. He’d smiled politely when she questioned him. He’d told her he worked nights because some people couldn’t afford to be seen. Tonight, a young man had gone into the bar under his own power. Twenty minutes later Herrera had emerged with blood on his cuff. He reached a bus stop, changed direction sharply and darted across the road in front of a cyclist. Quinn caught a glimpse of silver at his throat: the Saint Christopher medallion he always wore. The cyclist shouted. Quinn raised a hand in apology and followed. She got within arm’s reach outside a shuttered pharmacy. Herrera glanced back at the movement and swung an elbow. She caught his sleeve. The fabric tore between her fingers, and her grip slid down his left forearm. He hissed in pain. A long pale scar ran beneath her thumb. Then he twisted free. “I need to get this there,” he said. “Get what where?” He kept running. A night bus pulled up ahead. Herrera cut behind it, and Quinn lost him for three seconds in a wall of red metal and spray. By the time she cleared the bus, he was climbing into a black cab. “Camden,” she heard him tell the driver. Quinn slapped her palm against the rear window. Herrera ducked his head. The cab surged into traffic, leaving her standing in its exhaust. She got the registration. Her phone had one bar of signal. She sent the number and destination to the night desk, then flagged down the next cab. “Follow that one,” she said. The driver glanced at her warrant card and pulled out without a word. Through the smeared windscreen, Herrera’s cab drifted in and out of view. Quinn held her phone by the window, trying to make a call. No connection. She looked at the time on the dash. Well past midnight. The white disc troubled her. She had seen one like it on Morris’s desk three years ago, the morning before he died. Bone, he’d said, though she’d thought he was joking. It had a small hole bored near one edge and a notch that looked cut by hand. Morris had been tracing missing people through addresses that didn’t stay occupied. He’d gone to meet a source alone. They’d found him beneath a railway arch with no wound anyone could explain and rainwater in his lungs, though the street had been dry. Quinn had kept his case file when they told her to close it. The cab ahead turned north. She leaned forward. “Don’t lose him.” At Camden, Herrera paid and ran before the driver had stopped counting change. Quinn shoved a note at her own driver and got out into harder rain. Herrera crossed an empty street market, ducking between chained stalls and bins stacked for collection. Quinn followed at a measured run, close enough to hear his shoes slap through standing water. He didn’t look back now. He passed a locked service gate beneath the railway line and headed for a tiled entrance between two boarded shopfronts. No station name remained above it. Someone had painted over the sign in black, but the rain picked out the raised outlines of old letters. Herrera reached a steel door inside the entrance. He knocked three times, paused, then twice. A slot opened at eye level. Quinn stopped behind a pillar, breathing through her nose. A hand extended through the slot. Herrera placed the white disc in its palm. The door opened just wide enough to admit him. Light spilled over the tiles: warm yellow, moving shadows. She heard voices from below, too many for an abandoned station. The door shut. Quinn drew her phone. No signal. Her radio gave one sharp burst of static when she keyed it. She was alone under the old station canopy, with traffic a muffled wash behind her and Herrera on the other side of a locked door. She could wait for backup. That was the sensible choice. Whoever guarded the door might refuse her, but a team could cover the exits, obtain a warrant, make the place answer to a name and an address. Going in alone gave her no such advantage. A thin line of red appeared at the bottom of the door. For an instant she thought it was light. Then it lengthened across the tile and settled into a grout line. Blood. Herrera had not been bleeding when he left the Nest. Not enough for that. Quinn walked to the door and tried the handle. Locked. She struck the panel with the heel of her hand. The slot opened. A narrow face appeared behind it, one grey eye fixed on her. “Closed,” the man said. She held up her warrant card. “Metropolitan Police. Open the door.” The eye dropped to her badge, then to her empty hand. “Token.” “I need to speak to the man who just went in.” “Token.” Behind him someone cried out. The sound was cut short, though not before Quinn heard the raw strain in it. She pictured Herrera’s bloody cuff and the young man entering the Nest. “There’s an injured person in there.” “Then leave us to help them.” The slot shut. Quinn considered forcing the lock. Metal door, frame set into masonry. She had neither the tools nor the time. At her feet, the blood continued its slow passage through the grout. She stepped back into the rain and studied the entrance. To the right, a rusted railing bordered a stairwell choked with rubbish. On the other side of the rail, behind an old advertisement board, she found a maintenance gate held shut with wire. The knot was new. She pulled it loose. The gate gave enough for her to squeeze through sideways. Dark stairs fell away beneath her. Quinn used her phone’s torch and descended, keeping one hand free. Water dripped somewhere below. After twenty steps, the smell changed from wet brick to hot oil, smoke and something medicinally sweet. At the bottom, the passage opened onto a platform bright with lamps. She stopped in the shadow of an arch. Stalls filled the length of the abandoned station. Tarpaulins hung between tiled pillars. Glass bottles, bundles of dried roots and rows of small sealed boxes crowded tabletops. People moved through the aisles in raincoats, evening clothes, hospital scrubs. A woman with silver pins in her hair argued over a jar whose contents struck the glass from inside. Farther along, an old man sold maps from a suitcase, each sheet weighted at the corners with coins. A black sign above a ticket booth read THE VEIL MARKET in flaking gold letters. Beneath it, a board listed prices Quinn couldn’t make sense of. Some were in pounds. Others named favours. The place had electricity, security and customers. It had been operating beneath Camden while her missing-person inquiries sent her through empty buildings all over London. Quinn saw Herrera halfway down the platform. He pushed through a curtain beside a stall stacked with enamel basins. A heavyset woman followed him carrying a canvas medical bag. Quinn moved. She kept to the outer edge of the platform, where the stalls cast deeper shadows. Several people watched her. One man turned his face to the wall as she passed. She wanted to stop him, ask his name, demand to know how long the market had been here. Instead she followed the spot of fresh blood at the base of a pillar. A voice spoke close to her ear. “You have come down without paying.” Quinn turned. The grey-eyed man from the door stood behind a table of bone discs. Each had the same bored hole and hand-cut notch. He was taller than she’d thought, with a leather apron over a dark suit. “Then you know who I am,” she said. “I know what you showed me.” “I’m here for Herrera.” “He came to work.” A shout rose behind the curtain. Herrera’s voice, low and urgent. “Hold him still.” Quinn pushed past the man. He caught her wrist. His fingers closed over the worn leather strap of her watch. “You’ll frighten the sellers,” he said. She looked at his hand until he let go. Beyond the curtain, an alcove had been turned into a treatment room. A young man lay on a table under a bright work lamp. His shirt was cut open. Blood soaked the towels packed against his ribs. Herrera stood beside him with both hands inside the wound, pressing hard, while the woman from the platform worked a needle through torn skin. The patient’s eyes opened. They were dark and frightened. He tried to sit up. “Don’t,” Herrera said. He glanced at Quinn. Surprise crossed his face, then irritation. “If you’re going to arrest me, wait.” Quinn stepped closer. “Is he the man from the bar?” “Yes.” Herrera took a breath. “His name’s Ellis. He was attacked on the way out.” “By whom?” “I didn’t see.” The woman tied off a stitch. “Pressure, Tomás.” Herrera obeyed. His own cuff was soaked because he had held the wound. Quinn could see that now. The patient had a pulse beating visibly in his throat, much too fast. “Why bring him here?” she asked. “There’s an A&E ten minutes from the Nest.” “Because the last one we took to hospital disappeared before morning.” Quinn looked at him. His warm brown eyes held hers. She had heard him give evasive answers before; this wasn’t one. The woman cut another length of thread. Ellis made a broken sound through his teeth. “He needs blood,” Quinn said. “We have it.” Herrera nodded towards a cooler under the table. “He needs me to finish.” Quinn moved aside. Outside the curtain, feet hurried past. The market’s noise had changed. Traders were calling to one another in short, clipped phrases. Metal shutters rattled down somewhere along the platform. The grey-eyed man appeared at the entrance to the alcove. “Herrera. How long?” “Ten minutes.” “You have five.” Quinn stepped into his path. “What’s happening?” He looked beyond her at Ellis, then down the tunnel. “Someone followed you.” “I followed him.” “No,” he said. “Someone followed you.” The lights along the platform went out one by one. In the last spill of yellow, Quinn saw figures running for the stairwells. A shutter crashed between the treatment room and the market. She drew her phone again and hit the emergency call button. The screen showed no service. From the dark tunnel came a sound like a train taking a bend. The rails were brown with rust. Dust trembled on the platform edge. Herrera looked up from the table. “Quinn.” She turned towards him. “Help me move him.” The noise in the tunnel grew louder. Quinn put her phone away, stripped off her coat and took hold of the table’s far end. Ellis cried out when they lifted it. Herrera kept one hand pressed to his ribs as they carried him towards a narrow door at the back of the alcove. Quinn glanced over her shoulder. At the end of the platform, past the falling shutters, two lights appeared in the tunnel. They rode at the height of a train’s headlamps, growing brighter on rails that had not carried a train in years. She tightened her grip and helped Herrera get Ellis through the door.
