The man came out of the chemist’s with blood on his cuff and saw Quinn before she could turn away. For half a second, neither of them moved. Rain ticked against the plastic awning above him. His right hand tightened around the strap of a canvas medical bag. Under the streetlight, she caught the dull flash of a medallion at his throat. “Tomás Herrera?” He ran. Quinn went after him, her shoes slipping once on the wet pavement before finding purchase. A taxi sounded its horn as Herrera cut across Camden High Street. She followed through the gap behind it, close enough to smell hot rubber and diesel. “Police. Stop.” He did not look back. He was younger by twelve years and carrying less weight. She had a radio, cuffs, baton, phone, and eighteen years of knowing what happened when you followed a frightened man around a blind corner. None of it made her faster. Herrera cleared a low railing, landed badly, and kept going. The canvas bag struck his hip with every stride. Quinn pressed the transmit button on her radio. “Quinn. Foot pursuit, male suspect, northbound off Camden High Street. Dark jacket, medical bag. Request assistance.” A burst of static broke across the reply. She had watched him leave the Raven’s Nest forty minutes earlier. He had stepped out beneath its green neon sign and stood in the rain, reading a message on his phone. Through the bar’s open door, Quinn had seen old maps, black-and-white photographs, and a bookshelf swinging shut against the back wall. Herrera had caught the next northbound bus. She had followed in a cab. Now he was running with two refrigerated packets stolen from a chemist and blood that had not been there in Soho. He turned into an alley beside a shuttered food shop. Quinn slowed at the mouth, drew her torch, and took the corner wide. Empty bins. A broken pallet. Rainwater spilling from a downpipe. At the far end, Herrera shoved through a gate and vanished. She heard the gate bang against brick. “Control, suspect heading east through service passage. Possible knife injury. Confirm units.” “Detective Quinn, your last location—” The voice shredded. She moved. Beyond the gate, the passage narrowed between the backs of buildings. Restaurant extractors rattled overhead. The air smelled of old oil and wet cardboard. Herrera was twenty yards ahead, bent over now, one hand pressed against his side. Injured, then. That should have reassured her. Instead, she noticed he was not trying doors, not searching for a way out. He knew exactly where he was going. He turned left. Quinn reached the corner in time to see him at a steel door set into a wall streaked with rust. There was no handle, only a circular plate at shoulder height. Herrera pulled something pale from beneath his collar and pressed it against the plate. A small white disc. Not his medallion. The door opened inward. “Don’t.” He looked back. His face was slick with rain, short curls plastered to his forehead. She had expected calculation, the quick inventory of a man deciding whether he could fight. What she saw was fear. “Please,” he said. “Go back.” Then he stepped inside. Quinn caught the door before it closed. Its weight jarred her shoulder. A staircase descended into darkness. For a moment she stood with rain running down her neck and the door pressing against her palm. Below, footsteps struck concrete, then metal. A warm draught rose from the stairwell, bringing a smell she could not place: antiseptic under spices, with something sweet and rotten beneath both. Her radio crackled. “Quinn, do you require—” “Suspect entered underground premises. Steel service door, east side of—” She turned enough to search the alley for a street sign. There was none. She gave the last junction she could name and described the route from it. Then she wedged the broken end of a brick beneath the door. “Going below. Send units to the entrance.” “Wait for assistance.” The reply came clearly enough. Quinn looked down the stairs. Three years earlier, Morris had said those same four words. Not here. A basement in Wapping. A missing woman, a landlord with a clean record, a smell of spoiled flowers coming up through the floor. Quinn had been outside arranging a cordon when Morris went in ahead of the firearms team. They found him at the bottom of fourteen steps. No wound. No poison the laboratory could identify. His radio still working. The recording contained nineteen seconds of breathing, a noise like someone dragging a chair across stone, and Morris saying, very quietly, “That isn’t her.” Quinn had listened to it until she knew where every breath began. Below her, Herrera’s footsteps stopped. A door shut. She could wait. Let uniforms secure the exit. Get plans, establish another way in, do it properly. But Herrera had blood on his sleeve, refrigerated medicine in his bag, and the look of a man running towards someone who could not wait. She checked the time on the worn leather watch at her left wrist. Twelve minutes past midnight. Then she went down. The stairs were older than the door. Cream tiles appeared beneath layers of soot, their edges cracked and stained. Halfway down, she found a strip of faded advertising fixed to the wall: a smiling woman holding a cigarette. At the bottom stood an iron gate. Herrera was gone. Beyond the bars, light moved. Quinn gripped the gate and pulled. It opened without a sound. She stepped onto a disused Tube platform. For several seconds, the place refused to resolve into anything she understood. Canvas awnings stretched between iron pillars. Lamps hung from cables overhead, some electric, some burning with low blue flames. Stalls crowded the platform, leaving a passage down the middle. Beyond them, more stalls stood on boards laid across the tracks. People moved through the narrow aisles in raincoats and evening dress, boiler suits and clothes she could not classify. Someone was cooking meat over a brazier. Someone else stood behind a table of sealed glass jars, each full of pale objects suspended in amber liquid. The tiled station name had been chipped away. A woman beside the gate held out her hand. “Token.” Quinn turned towards her. The woman sat on a high stool, knitting something red with needles made of dark wood. Her hair was pinned tightly beneath a scarf. “Police.” “Token,” the woman repeated. Quinn showed her warrant card. The woman glanced at it. “That won’t get you back out.” “Where did the man with the medical bag go?” A few nearby conversations stopped. The woman put down her knitting. “He paid his way. You haven’t.” Quinn had heard enough variations of that in gambling rooms and unlicensed clubs. She let the card hang where the woman could still see it. “I’m not here for you. Don’t make that change.” The woman studied her, then leaned aside and opened a narrow wooden drawer. Inside lay a dozen discs like the one Herrera had used. Off-white, polished smooth, drilled at the centre. Quinn knew bone when she saw it. “Take one,” the woman said. “What is this place?” “The Veil Market.” “Who’s in charge?” That earned a laugh from somewhere behind Quinn. The woman took a disc from the drawer and pressed it into Quinn’s hand. “Keep it on you. And when someone asks what you’re buying, give them an answer.” Quinn closed her fingers around the token. It felt warm. She moved into the aisle. On the first stall stood bottles bearing handwritten labels: tinctures, salts, names that sounded like specialist drugs. Beneath them, packed in a tray of ice, lay three human fingers wearing gold rings. She stopped. The stallholder lowered a cloth over the tray. “Private collection,” he said. Quinn looked at his face, fixing it in memory. Her radio emitted a thin electronic whine. She turned the volume down and tried her phone. No signal. Along the nearest pillar, a notice announced that the market would leave Camden at the next full moon. Below that, another offered information for sale, payment in blood, coin, or recollection. A performance. An elaborate illegal market with a performance laid over it. She could work with that. Then one of the covered fingers began to tap against the metal tray. Quinn walked faster. She found a smear of fresh blood on a pillar at the platform’s far end. Beyond it, an archway led into a service tunnel. Light showed beneath a patched curtain hanging across its entrance. She heard Herrera’s voice. “Hold her shoulders. Not her wrists.” Quinn drew her baton and pushed through. The room beyond had once housed electrical equipment. Dead switchboards covered one wall. A surgical lamp had been bolted to the ceiling, and beneath it a young woman lay on a trestle table. Her shirt had been cut open along the ribs. Herrera stood beside her, pressing gauze to a wound. His jacket lay on the floor. A long scar ran along his left forearm, and his Saint Christopher medallion swung above the patient each time he leaned forward. An older man held the woman’s shoulders down. “Move away from her,” Quinn said. Herrera looked up. “You followed me.” “Hands where I can see them.” “If I take this hand away, she dies.” The patient’s eyes opened. She made a thin, breathless sound. Quinn stepped to the side for a clear view of the table. There was no obvious weapon. Scissors. Forceps. A syringe. Two silver packets torn open beside a steel bowl. The stolen medicine. “Who stabbed her?” “No one.” Herrera glanced at the older man. “Keep holding.” The man’s hands were shaking. Quinn kept her baton raised. “I can get an ambulance.” “No, you can’t.” “You were a paramedic. You know what happens if—” “I know exactly what happens.” His voice cracked across the room. Then he lowered it. “Look at the wound.” Quinn did not move closer. “Detective. Look.” Something shifted beneath the gauze. Herrera lifted its edge. The wound opened between two ribs. Within it, a black filament drew itself across the exposed flesh, jointed like an insect’s leg. It caught the light, recoiled, and disappeared beneath the skin. Quinn’s mouth went dry. The older man whispered, “It’s reaching her heart.” She forced herself to examine what she had actually seen. A parasite. Something imported, something rare. There would be a name for it. Herrera picked up the syringe. “Put that down,” she said. He met her eyes. “Arrest me afterwards.” From the market came the crash of a falling stall. The older man jerked his head towards the curtain. Herrera swore softly. Quinn heard footsteps. Slow, evenly spaced. Conversations stopped as they approached. “Who is that?” she asked. “The man who sold it to her,” Herrera said. “What?” “He promised it would cure her.” The patient began to convulse. Herrera braced a forearm across her hips and pushed the needle into the flesh below her ribs. Quinn caught his wrist. He went still. Under her hand, his pulse battered against the skin. “If you stop me,” he said, “you’d better be able to save her.” The footsteps stopped outside the curtain. A shadow divided the light beneath it. Two shoes, planted neatly side by side. Quinn heard a scrape from the other side. Wood across stone. Her grip loosened. Morris’s voice came back with terrible clarity. That isn’t her. The curtain stirred. “Tomás,” a man said. “You’ve taken something that belongs to me.” Herrera depressed the syringe. The woman arched off the table, mouth open in a soundless scream. The older man lost his grip. Quinn caught her shoulder before she could roll, feeling skin cold enough to hurt. Under the woman’s ribs, something thrashed. “Keep her down,” Herrera said. Quinn leaned her weight onto the shoulder. With his free hand, Herrera reached for the forceps. The curtain began to lift. “Metropolitan Police,” Quinn said. “Stay where you are.” The curtain stopped. For one heartbeat there was only the lamp’s electrical hum and the soft click of the forceps closing. Then the man outside laughed. “Of course,” he said. “Morris’s partner.” Quinn looked towards the curtain. Herrera pulled. A black strand emerged from the wound, twisting around the steel. It was longer than it should have been, wet and shining, tightening into knots as he drew it out. The patient gagged. Quinn held her down while Herrera dropped the thing into the bowl and clamped a lid over it. The lid rattled. Outside, the man sighed. “You could have left, Detective.” Quinn released the woman’s shoulder. Herrera immediately pressed fresh gauze into place. She took out her phone, opened the recorder, and set it beside the lamp. Then she picked up her baton. “What’s your name?” she asked. “You won’t remember it.” “We’ll see.” The bone token pressed against her thigh through the pocket lining. Behind her, Herrera tore open another packet. The patient drew a ragged breath, then another. Quinn stepped between the table and the doorway. She had come down without backup. She had no signal, no reliable exit, and no explanation for what was moving inside the covered bowl. But this time she was at the bottom of the stairs herself. “Tell me about Morris,” she said. The curtain lifted.
