The man looked back once, saw Quinn, and ran. He left his takeaway coffee spinning on the pavement outside the chemist. It burst under Quinn’s heel as she accelerated, hot liquid splashing her trouser leg. Ahead, Tomás Herrera slipped between two pedestrians and cut into the road without checking the traffic. A taxi braked hard. Its horn flattened every other sound. “Police! Stop!” Herrera didn’t stop. He vaulted the low rail beside a shuttered shop, his medical bag striking the metal with a hollow clang, and vanished down an alley. Quinn reached the rail three seconds later. She planted a hand, swung her legs across, and landed badly on her right foot. Pain shot up her ankle. She kept moving. Rain thickened in the alley, pouring from a broken gutter. Herrera’s trainers slapped through standing water twenty yards ahead. Short dark curls, blue jacket, black bag. She had watched him leave the Raven’s Nest forty minutes earlier, beneath its green neon sign. Before that, she had watched him disappear through a bookshelf at the back of the bar. Not into a corridor. Through a bookshelf. She could deal with the architecture later. “Control, Quinn.” She pressed her radio as she ran. “Foot pursuit. Male suspect, blue jacket, carrying a black medical bag. Heading north off Camden High Street.” Static scraped her ear. Herrera reached the alley’s end and turned left. Quinn followed into a narrow service road. A delivery van stood across half of it, engine running. Herrera squeezed between its rear bumper and a bollard. Quinn took the same gap, catching her coat on something sharp. Fabric tore. She dragged free without slowing. He was fast, but he was frightened. Frightened men wasted motion. They looked back. They chose bad ground. Herrera looked back again. “Tomás,” she shouted. “I know who you are.” That checked him more than the command had. His head twisted farther, and for an instant she saw his face clearly under a security light: olive skin slick with rain, mouth open, warm brown eyes sharpened by alarm. Then he turned into an enclosed yard. Dead end. Quinn slowed just enough to keep her footing. Brick walls rose on three sides. Two overflowing bins stood beneath a rusted fire escape. At the far end, a corrugated steel door sat under a faded warning about electrical equipment. Herrera was at the door. “Put the bag down.” He fumbled inside his jacket. “Hands where I can see them.” “It’s not a weapon.” “Then show me.” He withdrew something pale and small. Not a knife. A piece of bone, roughly the size of a large coin, with a hole bored through its centre. He pressed it against the steel. A bolt withdrew on the other side. Quinn stopped. There was no reader. No keypad. Nothing but wet metal and the ruin of an old padlock hanging from a hasp. Herrera pulled the door open. Warm air rolled into the yard, carrying the smell of frying oil, damp wool and something medicinal. “Don’t come after me,” he said. “Then don’t run.” “You don’t understand.” “People keep telling me that.” He hesitated. His Saint Christopher medallion had slipped from his collar and lay against his shirt, catching the light. The scar along his left forearm showed where his sleeve had ridden up. Quinn knew the scar from his file. Knife assault, four years ago. Former NHS paramedic. Registration lost after a series of unauthorised treatments and a disciplinary hearing in which half the clinical notes had disappeared. The bag mattered more than the disciplinary hearing. Three nights earlier, a courier had been found dead in a locked flat, his blood almost entirely gone. Security footage showed Herrera entering the building with that same black bag. “You were at Mercer House,” Quinn said. His expression changed. “I tried to help him.” “What was his name?” Herrera said nothing. “If you treated him, you know his name.” From somewhere beyond the door came a bell. Two low notes. Herrera glanced down into the darkness. “I’m sorry,” he said, and slipped inside. Quinn lunged. She caught the door before it closed, steel biting into her palm. A flight of steps descended beyond it. Old tiled walls. An iron handrail. Yellow light glowed far below. At the first landing stood a woman in a heavy black coat, holding out an open hand. “Token.” “Police.” “Token.” Quinn showed her warrant card. The woman didn’t even look at it. Behind Quinn, a car passed the mouth of the service road. Normal traffic, normal streetlight. She could step back into the yard, call for assistance, put officers on every exit she could find. Do it properly. She checked her radio. “Control, do you receive?” Only static. Herrera’s footsteps were fading below. The woman’s gaze moved to the door in Quinn’s hand. “You can wait outside,” she said. “You can’t wait there.” Quinn looked down at the steps. A wet white object lay against the wall where Herrera had turned too quickly. The bone token. She picked it up. It was warmer than it should have been. The woman examined it, then closed Quinn’s fingers around it with a dry, firm grip. “Leave when the bell rings three times.” “What’s down there?” “Things you should leave alone.” Three years ago, Morris had stood at the mouth of a warehouse and told her to wait for backup. She had obeyed. She had watched his torch move between the boarded windows, then go out. They never found his body. Quinn put the token in her pocket and descended. The stairs bent sharply twice. With each turn, street noise diminished until she could hear only water dripping from her coat and the faint rasp of her breathing. Her watch strap had loosened in the rain. She pushed it higher on her left wrist. At the bottom, the passage opened onto a disused station platform. Stalls stood beneath the curved roof, wedged between tiled pillars. Lamps burned in glass jars. Canvas awnings hid sections of the ceiling. The track bed had been boarded over to make a central aisle, and people moved along it carrying parcels, cages and bundles wrapped in oilcloth. Quinn smelled coffee, hot copper and the sweet rot of flowers left too long in a vase. A hand-lettered sign hung from a pillar. VEIL MARKET. NO CREDIT. NO CLAIMS AFTER THE MOVE. Beneath it, someone had chalked a date and a full moon. She had seen the name in statements. Always second-hand, always quickly withdrawn. A market that moved around London. A market you couldn’t enter without paying something other than money. She had assumed it was a way of keeping frightened witnesses quiet. Herrera pushed through a knot of customers halfway down the platform. Quinn followed. At the nearest stall, little bottles stood in ranks inside a locked cabinet. Several contained liquids that climbed the glass instead of settling at the bottom. A vendor shut the cabinet as she passed. She kept her eyes on the blue jacket. “Excuse me.” A broad man carrying a covered birdcage stepped into her path. She shifted around him, and something inside the cage hit the bars with enough force to dent the brass. The man murmured to it. Quinn increased her pace. Herrera disappeared behind a canvas screen at the far end of the platform. She reached it and pulled the cloth aside. He stood beside a folding table. His bag was open, revealing bandages, syringes and a compact oxygen cylinder. On the table lay a young woman in a grey sweatshirt, one sleeve soaked dark. A man in a butcher’s apron held her wrist down. Herrera looked up. “Not now.” “Step away from her.” “She’s bleeding.” The young woman’s face was waxy. Blood pooled beneath her upper arm and dripped steadily off the table. Quinn moved closer. She saw the wound then: a deep slash just above the elbow, with something narrow and black embedded in it. The man in the apron released the patient’s wrist and reached beneath his workbench. “Don’t,” Quinn said. He froze. She unfastened her baton. “Hands on the bench.” Herrera pressed a pad against the wound. “That won’t help.” “Then tell him to keep his hands where I can see them.” “I meant her.” The young woman jerked. Her heels struck the table. Herrera leaned his weight onto the dressing. “Hold this,” he told Quinn. She looked at the apron, the bench, the man’s concealed hand. “Now.” Quinn caught the man by the wrist, dragged his hand into view and found it empty. She shoved him back from the table, then took Herrera’s place on the dressing. Warm blood soaked her palm almost immediately. Herrera pulled scissors from his bag and cut the sleeve away. His movements changed. The flight, the panic, the clumsy scramble at the door—all gone. He worked quickly and without hesitation. “Who did this?” Quinn asked. “Someone she couldn’t pay.” The man in the apron edged towards the screen. “Stay there.” He stayed. Quinn pressed harder. Beneath the torn fabric, the black sliver seemed to move. She blinked. Herrera took a pair of forceps and a glass vial from his kit. “Keep your hand steady.” “What is that?” “Something that should never have been sold.” He gripped the sliver. The young woman arched off the table, teeth snapping shut on a scream. Quinn held her shoulder with her free hand. For a second, the thing resisted. Then Herrera pulled it clear. It writhed between the forceps, thin as a broken needle, and struck the metal with a sharp clicking sound. He dropped it into the vial and screwed on the lid. The bleeding slowed. Quinn stared at the vial. “Look at me,” Herrera said. She did. “Keep pressure there. Whatever you’re thinking, do it later.” He threaded a needle. Beyond the screen, the market continued around them. Coins clinked. Somebody laughed. A vendor called out a price. Quinn watched Herrera close the wound. “The man at Mercer House,” she said. “Was it one of those?” “No.” “Then what happened to him?” “I got there too late.” “Who sent you?” He didn’t answer. The man in the apron made a sudden movement. Quinn turned, baton half drawn, but he wasn’t coming towards her. He was gathering objects from the bench into a cloth sack. A ring. A silver lighter. A leather wallet. A police badge. She saw the number before his hand closed around it. For eighteen years she had worked beside men and women whose numbers she could barely remember. Morris’s she had put on missing-person notices, internal reports, appeals. She knew every digit. “Put that down.” The man stopped. Quinn left the dressing. Herrera immediately took over. “The badge,” she said. “On the table.” “Everything here has a price.” She caught his apron in her fist and drove him against the tiled wall. “Where did you get it?” His head struck a tile. He winced but kept hold of the sack. “Bought it.” “From whom?” “You won’t find him up there.” Quinn tightened her grip. Herrera said her name. She ignored him. “Where?” The trader looked past her. A bell sounded. Once. Conversations outside broke off. Quinn heard canvas tearing down, crates scraping across boards. The trader smiled without showing his teeth. “You should have stayed outside.” A second note rolled through the station. Herrera stripped off his gloves. “We need to move.” Quinn pulled the sack from the trader’s hand. He tried to catch her wrist. She drove the heel of her hand into his chest, and he folded against the wall. She tipped the sack onto the bench and picked up the badge. Morris’s warrant card was tucked beneath it. The photograph had faded. His grin hadn’t. For a moment she could smell the inside of his car: old coffee, peppermint, the wet dog he insisted he didn’t own. Herrera caught her arm. “Quinn. Listen to me. She can’t walk.” The patient had opened her eyes. She was looking at Quinn without understanding where she was. Outside, lamps were going out. Quinn pocketed the badge and card. “Take her legs.” They lifted the young woman off the table. She cried out as her injured arm fell sideways; Quinn caught it against her chest. The trader slipped past them through the screen. Quinn could have dropped the woman. She could have followed him. Instead she backed into the aisle. The station had changed in less than a minute. Half the stalls were bare. People streamed towards doors she hadn’t noticed on the way in. At the far end, beyond the stairs, something heavy struck the boards from underneath. “Don’t stop,” Herrera said. They carried the woman between them, Quinn walking backwards, watching the dark gaps beneath the dismantled stalls. Her ankle burned. Blood made her grip slippery. The stairway seemed impossibly far away. “Who’s moving the market?” she asked. “Not now.” “Then when?” “When we’re out.” They reached the passage as the third bell began. Quinn hauled the woman higher. Herrera stumbled on the first step, recovered, and kept climbing. Behind them, the boards split. She didn’t look back. At the top, the woman in the black coat held the steel door open. Rain shone beyond her. “Quickly.” They crossed the threshold together. The door slammed, cutting off a sound Quinn could not have put in a report. Herrera lowered the patient onto the wet pavement. Quinn shrugged off her coat and tucked it beneath the woman’s head. Her radio crackled. “Quinn, confirm location. Quinn?” She pressed the button with a bloody thumb and gave the address. “Ambulance required. Female, severe blood loss. And send units to cover the surrounding streets.” Herrera sat back on his heels. Rain ran down his face. “Am I under arrest?” Quinn took out Morris’s warrant card. The rain struck the plastic. She shielded it with her hand. “You’re coming with me,” she said. Herrera looked at the closed steel door. “Yes,” he said. “I think I am.”
