The man came out of the alley with blood on his sleeve and collided with a cyclist outside Camden Town station. The bicycle hit the kerb. Its rider went over the handlebars. By the time the man had found his footing, Detective Harlow Quinn had crossed the road. “Tomás Herrera. Stop.” Herrera looked back. Rain flattened his dark curls against his forehead. His hand went to the Saint Christopher medallion at his throat, then dropped to the front of his jacket. He ran. Quinn stepped around the fallen bicycle and gave chase. A bus swung between them, its tyres throwing gutter water across her trousers. She caught a glimpse of Herrera through the windows, weaving past a knot of people under the station awning. When the bus cleared, he had turned into Camden High Street. “Police. Make room.” Two men carrying takeaway boxes pressed themselves against a shutter. Quinn drove through the gap. Her shoes struck wet pavement and skidded on a crushed paper cup. Ahead, Herrera crossed against the lights. A taxi braked hard enough to sound its horn in one long blast. Quinn took a narrower crossing behind him, close enough to see the strip of pale skin along his left forearm. She knew that scar from the photographs pinned to her office wall. Former paramedic. Lost his licence. Treated people who refused hospitals and, if her source at the Raven’s Nest had told the truth, charged nothing when they came in close to death. Tonight he had come out of the bar’s hidden room carrying a canvas satchel. He had left without it. At the next junction, Herrera glanced over his shoulder. Quinn held up her warrant card. “I need to speak to you about the man at the Nest.” Herrera’s face changed. He knocked into a woman’s umbrella, caught its handle before it fell, and pushed on. “He was alive when I left,” he called. “Then help me find him.” A motorbike cut across Quinn’s path. She stopped short, let it pass and reached for her radio. “Control, Detective Quinn. Pursuing Tomás Herrera on foot, northbound Camden High Street. Olive skin, dark jacket, thirty. Possible connection to an assault in Soho.” Static broke across the reply. She caught her name, then nothing. The display showed a signal. She tried again. Herrera had left the crowded frontage. He cut through a side street where the shop lights gave way to brick walls, locked gates and overflowing bins. Quinn followed the sound of his shoes slapping through puddles. A chain-link fence ran along one side of the road, screening a strip of derelict railway land. At the far end, a work lamp shone above a boarded service entrance. Herrera reached it first. He leaned against the boards, breathing hard. “Don’t come down here.” Quinn slowed. Ten yards separated them. Water dripped off the end of his nose. Blood had soaked the cuff of his jacket and run over the old knife scar. “Show me your hands.” He raised one. In it lay a small white disc with a hole through its centre. Bone, Quinn thought. His other hand stayed pressed against his ribs. “You’re hurt. I can get you an ambulance.” “Send one to the Nest. The man upstairs needs it more.” “The man upstairs gave me your name.” Herrera shut his eyes for a beat. Behind him, a thin line of darkness appeared between two boards. Quinn heard metal scrape against metal. “What did he tell you?” “He told me you could explain what happened to him.” “He could still talk?” “He could when I left.” Herrera looked at the opening behind him. For the first time since the chase began, he seemed less concerned with Quinn than with reaching whatever lay below. “Go back and keep him talking. Ask what he bought.” “Bought where?” The gap widened. A slab of plywood swung inward on concealed hinges, revealing concrete steps under an old railway sign. The lettering had peeled away, but Quinn could make out the edge of a station roundel. Herrera slipped through. Quinn ran the last few yards. A figure stood beyond the opening, wrapped in a long oilskin coat. One hand caught Herrera’s elbow; the other took the white disc. The figure turned its head towards Quinn. Strips of cloth covered its nose and mouth. “Two of you?” it asked. “One,” Herrera answered. “Close it.” Quinn planted her palm against the plywood. The figure shoved from the other side. For a second the opening narrowed around Quinn’s arm, trapping the sleeve of her coat. She twisted free and forced her shoulder through. The board struck the wall behind her. The figure retreated down the stairs. Herrera stumbled after it. “Police,” Quinn called. “Stay where you are.” The figure stopped at the next landing. Quinn took two steps down, then saw three more shapes below it, standing in the dark between the railings. One carried a hooked pole. Another held a glass jar against its chest. Pale things moved inside the jar, striking the sides with small dry taps. Quinn kept her right hand near her cuffed holster. She had come in without a partner. Control had her last street-level position, if the radio transmission had reached anyone. Behind her, rain struck the pavement; ahead, the stairs dropped past the reach of the work lamp. Herrera gripped the railing. Blood ran between his fingers. He looked up at Quinn. “You can arrest me when I come back.” “What’s down there?” “A place where I can get something to keep him alive.” “Name it.” Herrera opened his mouth. The figure in oilskin lifted the bone token into the light. It showed a pattern of tiny punched holes. Its knuckles bent where knuckles did not belong. “The Veil Market,” Herrera told her. “Under the old station.” Quinn glanced at the figure’s hand. The cloth over its face rose and fell with a slow breath. Far below, voices travelled up the stairwell: a man calling prices, someone arguing in a language Quinn did not know, a woman laughing once before a gate crashed shut. Light flickered across the concrete walls, green, then amber. An old rail map hung at the landing, its glass painted over in black. Three years earlier, DS Morris had vanished at a sealed station entrance during a case that should have ended with a search warrant and two arrests. Quinn had stood on the other side of a steel door while he struck it from within. By the time the fire crew cut through, the room had been empty. She had kept the recording of his last radio call on a drive in her desk. Every review had given her the same burst of static and one breath. The figure in oilskin lowered the token towards a brass slot in the wall. “Is she coming?” it asked. “No,” Herrera answered. Quinn took another step down. “I’ll answer for myself.” Herrera swore under his breath. “You don’t have a token.” “I’m not buying anything.” “That won’t matter to the gate.” The oilskin figure pressed the token into the slot. Somewhere below, machinery clanked into motion. A barred gate at the foot of the flight began to rise, inch by inch. Quinn studied the three waiting figures. None had moved towards her. Herrera had reached the landing but stopped there, one arm folded tight across his ribs. Beneath his jacket, the wound must have opened during the run. He had enough strength to make it to the gate. She could turn back, call for officers and an ambulance, and put a car on every exit she could find. The man at the Nest might die before Herrera returned. The gate might shut with Herrera on the other side. Her radio crackled. “Quinn? Repeat your location.” She pulled it free. “Abandoned station access off the service road east of Camden High Street. Need medical response at the Raven’s Nest, Soho. Male victim with serious injuries. Send officers to my location.” “Received. Are you with the suspect?” Quinn looked at Herrera. He watched the gate rise. “Yes. I’m following him.” She clipped the radio back to her coat and descended. The figure with the jar stepped aside. As Quinn passed, one of the pale things inside opened a mouth against the glass. She kept her eyes on Herrera. At the bottom, the gate stood high enough for a person to duck beneath. Beyond it stretched a disused platform packed with stalls. Bare bulbs hung from pipes above tables covered in jars, knives, folded clothing and bundles of paper tied with red string. Rainwater ran down the tiled wall and collected along the platform edge. Across the tracks, a train carriage sat without wheels, its windows lit from inside. A woman at the nearest stall pulled a tarpaulin over her goods when she spotted Quinn’s warrant card. Two customers moved away from the gate. Neither wore a coat, though water dripped from the ceiling onto their bare shoulders. Herrera took three steps onto the platform and caught himself against a pillar. Quinn reached him before he slid down it. Blood covered her hand when she gripped his jacket. “You’re going to sit.” “Not here.” He pointed along the platform. “Blue awning. Woman with a silver tooth. Ask her for black salt and a sterile needle.” “For you?” “For the man in Soho. I’ve got what I need for this.” He pulled a packet of gauze from his pocket and pressed it into Quinn’s bloody hand. She looked down at it, then at the open wound beneath his sleeve. “Hold your arm out.” The figure in oilskin remained at the gate, watching them. Quinn tore the packet open with her teeth. Herrera braced his hand against the pillar while she pressed the gauze to his forearm. His jaw locked. “Tell me what happened at the Nest.” “He opened a bottle he bought down here. I told him not to break the seal.” “What was in it?” Herrera watched a thin trail of blood slip past Quinn’s thumb. “I didn’t see it. He dropped the bottle when it bit him.” From somewhere under the platform came the rumble of a train, though the tracks in front of Quinn lay rusted and broken. She kept pressure on the gauze. Herrera pointed again, past a row of hanging lamps to a patch of blue canvas. “Silver tooth,” he repeated. “You’ll see her behind the scales.” Quinn adjusted her grip and walked with him along the platform.
