Tomás Herrera came out of the chemist’s side door with blood on his cuff and a black medical bag under his arm. He saw Quinn across the road and stopped so abruptly that the woman behind him nearly walked into his back. Then he ran. Quinn stepped off the kerb. A bus shouldered past, throwing rainwater over her shoes, and for three seconds she lost him behind its windows. When it cleared, Herrera was already halfway down the next block. “Police! Stop!” He glanced back. He had warm brown eyes and a Saint Christopher medallion that flashed at his throat as he turned. She had watched him for six nights, long enough to know he could slip a crowd without seeming to hurry. Tonight he was hurrying. Quinn ran. The rain made the pavement shine like black glass. Herrera cut between two men outside a kebab shop, vaulted a low chain, and knocked a stack of plastic crates into her path. Quinn clipped one with her shin. It spun away, and she kept going. In her coat pocket, her phone vibrated. Dispatch, probably. She had called in her location before following Herrera into the chemist. She let it ring. By the time someone else reached Camden, he would be gone. The chemist’s owner had reported missing morphine twice in the last month. Herrera had lost his paramedic licence years ago, but people still came to him for treatment. That had been enough to interest Quinn. The photograph on his phone, taken tonight through the chemist’s back window, had made her follow him: a young man lying on the dispensary floor while Herrera pressed a blood-soaked towel to his chest. The man had got up and walked away before Quinn could reach the door. She had watched him go. The blood had remained on the floor. Herrera crossed at the lights against a red signal. A taxi braked hard and sounded its horn. Quinn followed, one hand raised to stop the driver climbing out after them. Beyond the crossing, Herrera turned down a narrow street lined with shuttered shops. Her watch showed eleven forty-eight. He had taken the same route two nights ago, though then he had carried no bag and Quinn had lost him near the canal. She knew where this street ended: a brick wall beneath a railway viaduct. No through road, no entrance to the station. He was running into a trap. Herrera looked over his shoulder once more. He was younger than her by more than a decade, but his face had the drawn, sleepless look she knew from hospital waiting rooms. He saw that she was still coming and reached into his jacket. Quinn slowed and brought her hand to her holster. He pulled out something small and pale. It slipped from his fingers, struck the pavement, and skittered under a parked van. Herrera kept running. Quinn could have left it. Instead she crouched and reached beneath the van’s dripping chassis. Her fingertips found a disc no larger than a pound coin. Bone, polished smooth on one face and scratched on the other. She pocketed it and ran on. At the wall, Herrera had vanished. Quinn stopped beside a boarded-up entrance marked with the faded roundel of a Tube station. The stairs beyond the boards had been closed for decades; she had checked the maps after losing him here the first time. Rain pattered on the plywood. A train rolled somewhere overhead, shaking dust from the viaduct. She caught a scrape from inside. Quinn drew her torch and pushed against the boards. One moved inward. Behind it stood a heavy steel door, open a hand’s width. She slipped through and found stairs descending into darkness. Her phone rang again. She answered. “Quinn.” She kept her voice low. “Where are you?” Sergeant Iqbal asked. “Uniform’s five minutes out.” “Old station entrance off Hawley Street. Herrera’s gone inside.” “Wait for them.” Quinn aimed her torch down the steps. Water trickled along one edge. Halfway down lay a fresh red print, the shape of fingers dragged across a tile. “He may have someone hurt down here.” “Quinn—” The line crackled. From below came a woman’s voice, sharp with anger, then a sound like a shutter slamming. “Send them to the entrance,” Quinn said. “Tell them not to seal it.” She ended the call before Iqbal could answer. The stairwell smelled of wet concrete and hot metal. Quinn descended with her torch in one hand and her other free. At the bottom, a passage opened onto a disused ticket hall. Grimy white tiles reflected a light that had no business being there: amber, blue, a thin violent green. Voices filled the space beyond an archway. A man stood beneath it in a dark wool coat. He was broad enough to block most of the opening. When Quinn approached, he looked at her hand rather than her face. “Token,” he said. Quinn stopped. Through the gap beside him she saw stalls crowded along an old platform. Lamps burned over tables covered in bottles and folded cloth. People moved between them, their heads bent close as they talked. She glimpsed Herrera’s dark curls disappearing into the crowd. She took the bone disc from her pocket. The man held out his palm. “What is this place?” she asked. “Token.” She showed him her warrant card instead. “Metropolitan Police. Move aside.” His gaze stayed on the disc. “You can walk back up the stairs.” Something shifted behind him. Quinn moved her torch and caught a face between two hanging rugs. Its eyes shone silver in the beam. The person turned away too quickly for her to make sense of what she had seen. Herrera was getting farther away. Quinn put the disc in the man’s palm. He turned it over with his thumb. A shallow notch marked the edge. His thumb stopped on the scratched face, and his expression changed. “Who gave you this?” “He dropped it.” The man looked into the market, then back at her. For the first time, he seemed uncertain. He stepped aside. Quinn went through before he could reconsider. The abandoned platform stretched farther than her torch reached. Somebody had strung electrical cable along the ceiling; bare bulbs hung over traders’ tables. An old station sign read CAMDEN TOWN beneath a newer smear of black paint. The tracks were hidden under wooden decking, leaving only a dark trench along the platform’s far edge. Herrera stood at a stall near the middle. He had opened his bag. A woman with a split lip leaned against the counter while he wrapped something around her wrist. Blood dripped steadily from her sleeve onto the wood. Quinn moved toward him. Conversations faltered as she passed. A man selling sealed glass jars pulled a cloth over them. At another table, rows of teeth lay arranged on black velvet, each tied with red thread. Quinn fixed her eyes on Herrera. “Hands where I can see them,” she called. He looked up, finished fastening the bandage, and said something to the injured woman. She disappeared between the stalls. Herrera closed his bag. “You shouldn’t have come down,” he said. “Then you shouldn’t have run.” He glanced past Quinn, toward the entrance. The man in the wool coat remained under the archway, watching them. Quinn took out the disc. “You dropped this.” Herrera’s face tightened. “I know.” “You wanted me to follow.” “I wanted you to find the door. I thought you’d wait for help before you came in.” She looked at the scratches on the bone. Under the market lamps they resolved into letters and numbers: MORRIS, followed by his warrant number. For an instant she heard rain against a different roof. Three years ago, she and DS Morris had entered a boarded-up house on a missing-person call. He had gone ahead of her down a hall. By the time she reached its end, he was gone. There had been no door, no broken window, nothing for the search team to find. His warrant card had still been in his pocket when she last saw him. Quinn closed her fingers around the token. “Where did you get this?” Herrera’s eyes went to the engraved name. “At the Raven’s Nest. Someone brought it to the back room tonight. They said it would get you here.” Quinn pictured the Soho bar: green neon over the entrance, old maps and black-and-white photographs on the walls. She had followed Herrera there the previous week. He had gone behind a bookshelf with two people carrying a wounded man between them. Quinn had waited outside for them to emerge. They never had. “Who brought it?” “I didn’t get a name.” “Describe them.” Herrera shook his head. “We need to leave. That woman was cut getting out of the lower tunnel. Whatever did it followed her.” A metallic bang rang from the far end of the platform. Every head turned. Beyond the last stall, where the tunnel curved away into blackness, a shutter began to rise. It lifted an inch, stopped, and shuddered against its frame. A trader seized the edge of his tablecloth and swept his wares into a box. Others started toward the exit, pressing around Quinn. Herrera caught his bag and pushed through them toward her. Quinn held her ground. “Morris came here?” “I don’t know. The token has his name.” The shutter struck its frame again, harder. Along the platform, bulbs flickered. Quinn could hear a sound beneath the crowd’s footsteps, a slow dragging noise from inside the tunnel. Her phone showed no signal. Uniform was above, five minutes out when Iqbal called. Perhaps three now. Between them and her stood the man at the archway, who had admitted her on a token bearing a dead man’s name. Herrera reached her. “Detective.” She wanted to seize him by the collar and make him tell her everything he knew. Instead she looked down the platform. The shutter rose another inch. In the gap below it, something pale moved across the tiles. The woman with the injured wrist stumbled out from between the stalls. Her bandage had soaked through. Herrera went to her at once, putting her good arm over his shoulders. Quinn backed toward the archway with them, keeping her torch trained on the shutter. The dragging stopped. For one second the market went quiet enough that Quinn heard rain running down the stairwell behind her. Then the shutter buckled outward. Quinn grabbed Herrera’s bag strap and pulled him and the woman toward the exit. “Move.” They reached the ticket hall as the first bulb burst behind them. Quinn did not look back. She could hear people running on the platform, and beneath them, something coming fast along the tiles.
