Rain ran down the back of Detective Harlow Quinn’s collar as Tomás Herrera burst out of the side door of a Camden pharmacy. He struck the pavement with one hand, caught himself and ran. Quinn followed. “Tomás. Stop.” He glanced over his shoulder. The pharmacy’s security light caught his face, then the black medical bag banging against his hip. Blood marked the cuff of his jacket. His left hand clamped the bag shut. A cab cut across Quinn’s path. She slapped its bonnet, vaulted the kerb and landed in the road behind Herrera. The driver leaned on his horn. Herrera had already slipped between two buses waiting at the lights. Quinn had watched him leave the Raven’s Nest twenty minutes earlier. He had come out beneath its green neon sign carrying the same bag, his head down against the rain. She had followed his bus north from Soho in an unmarked car. Outside the pharmacy, a man in a hood had handed Herrera a parcel and run when Quinn showed her warrant card. Herrera had run too. She pressed the button on her radio. “Quinn. Suspect on foot, northbound towards Camden High Street. Dark jacket, medical bag.” A burst of interference swallowed the reply. She clipped the radio back onto her belt and pushed through a knot of people outside a late-night takeaway. Herrera cut into an alley beside a shuttered record shop. Quinn followed him past bins that smelled of sour beer. At the far end, a chain-link gate stood open by the width of a shoulder. He turned sideways and slipped through. “Save yourself the trouble,” she called. “I saw the handover.” He stopped beyond the gate. For a moment she thought he meant to answer. Then he looked past her, towards the street, and pulled the gate shut. The latch caught before Quinn reached it. Herrera turned away. She drove her shoulder into the mesh, found the latch with two fingers and forced it up. By the time she got through, he had crossed a small service yard and vanished behind a pair of iron doors. One door struck the wall as she reached it. Beyond lay a stairwell tiled in grimy cream, its steps falling out of sight. A faded Underground roundel hung above them. Someone had painted over the station name, though the letters beneath still read CAMDEN. Herrera’s footsteps rang below. Quinn took the stairs three at a time. The city noise thinned behind her. Halfway down, she caught the smell of hot metal and incense. Voices rose from below, too many for an abandoned station. At the bottom of the first flight, Herrera struggled with a narrow door set into a security grille. A large woman stood on the other side, her hand resting on a steel bolt. “Herrera.” Her voice carried up the stairwell. “You brought company.” “She’s police. Let me through.” The woman looked up at Quinn. Her eyes rested on the warrant card Quinn held out. “Then you can wait with her.” Herrera pulled something pale from his jacket pocket. Quinn saw a small disc strung on red cord. As he thrust it towards the grille, she caught his wrist. The old scar along his left forearm showed white beneath his soaked sleeve. “Bag on the floor.” “Get off me.” He drove his elbow into her ribs. Quinn kept hold of his wrist and struck the grille with her shoulder. The disc fell between them, hit a step and rolled. Herrera twisted free. The woman threw back the bolt, hauled him inside and slammed the door against Quinn’s outstretched hand. It caught her fingertips. She pulled them clear before the bolt dropped. “Herrera!” Through the grille, she saw him hurry down another flight. Light spilled up from below: red, amber and a green that shifted across the tiles. The woman stayed beside the door. “Open it.” Quinn held up her warrant card. “Metropolitan Police.” “You can read the sign at the top, then.” “This station’s closed.” “Looks busy from here.” Quinn bent and picked up the disc. It was bone, worn smooth at its edges, with a hole drilled through its centre. A shallow groove divided one face into four unequal parts. Herrera’s wet thumbprint marked the other. The woman’s expression changed when she saw it. “Where did you get that?” “He dropped it.” “That belongs to him.” “Open the door.” The woman tightened her grip on the bolt. “Give it back when you catch him.” She slid it free. Quinn pulled the door open, then paused on the threshold. Her radio had gone quiet. Behind her, the stairs led to a street full of witnesses, traffic cameras and officers who would come if she called again. Ahead, Herrera disappeared around a bend beneath the tracks. He knew the way through. She did not. The woman held out a hand for the token. Quinn put it in her coat pocket and stepped through. “What’s your name?” she asked. The woman pushed the grille shut. “Ask him.” Quinn descended past a boarded ticket window and a row of machines with their screens torn out. She rounded the bend and stopped at the platform entrance. Stalls filled the space where passengers should have stood. Canvas awnings stretched between tiled pillars; wires carried bare bulbs over tables crowded with bottles, rusted keys and trays of teeth. A man held a glass vial to the light while something inside it beat against the cork. Farther down, a woman argued over a parcel wrapped in butcher’s paper. The rails had disappeared beneath wooden decking, though Quinn could see black water between the boards. No one wore a uniform. No one looked surprised to see her. Herrera moved through the crowd on the far side of the platform, his medical bag tucked beneath one arm. He glanced back and saw her. For the first time since the pharmacy, he slowed. Quinn pushed forward. A stallholder drew a curtain of hanging charms across her path. She swept them aside; bone and brass knocked against her wrist. “Police. Move.” The stallholder caught one swinging charm before it struck a lamp. “You’ll pay if you break it.” “Send me a bill.” Herrera ducked behind a pillar painted with an old advertisement for soap. Quinn went after him. A boy carrying a stack of empty crates stepped into her way, and she caught the top one before it fell. “Where’s he gone?” The boy stared at her warrant card, then past her shoulder. Quinn turned. A man in a long grey coat stood at the platform entrance she had just crossed. He spoke into the ear of the woman from the grille. She pointed towards Quinn. The man started down the platform. Quinn set the crate back on the stack and moved. Beyond the soap advertisement, a table displayed surgical instruments on black velvet. Several bore handles shaped from materials she could not place. Herrera stood there with the stallholder, passing over the parcel from the pharmacy. The stallholder peeled back one fold of paper. Quinn caught a glimpse of a glass ampoule packed in straw. “Herrera. Hands where I can see them.” He snatched the parcel back. The stallholder pulled his hands clear. “Don’t bring this to my table,” he told Herrera. “You told me to come here.” “I told you to come alone.” Quinn closed the distance between them. Herrera backed towards a narrow gap between the stalls. “The man outside gave you that parcel,” she told him. “I want to know what’s in it.” Herrera looked at the grey-coated man approaching from the other end of the platform. Rainwater dripped from Herrera’s curls onto his cheeks. His Saint Christopher medallion had slipped outside his shirt. “Not here.” “Put it down.” “He needs it.” “Who does?” Herrera’s eyes shifted to the passage behind Quinn. She heard a cry from deeper in the station, short and raw. Several people turned towards it. Herrera used the movement to slip into the gap. Quinn caught the strap of his bag. It jerked against her palm as he pulled away. “Enough.” “Then let go.” The grey-coated man reached the stall and planted himself beside the instruments. The stallholder drew his velvet cloth over them. Quinn drew Herrera back by the strap. The medical bag struck the table, and a steel tray fell to the boards with a crash. Herrera twisted towards her, one hand still wrapped around the paper parcel. “Open the bag,” Quinn ordered. He stared at her. The cry sounded again from the passage behind him. He set the parcel on the table, kept one hand on it and reached for the bag’s zip.
