Rain stippled the Camden pavement and turned the shutters of the closed shops into dull mirrors. Quinn stood beneath a chemist’s awning, water crawling from her cropped salt-and-pepper hair, and watched Tomás Herrera emerge from a lock-up opposite. He carried a medical bag in his left hand. His sleeve had ridden up, exposing the pale seam of a scar along his forearm. He checked both ends of the street before stepping out. Three hours opposite the Raven’s Nest had earned Quinn wet socks and a numb backside. The bar’s green neon had shimmered on the Soho pavement while people came and went beneath it, none of them doing anything she could put in a report. Then Herrera had slipped through the side door, taken a minicab to Camden and disappeared into the lock-up with a key of his own. Quinn crossed the road. “Tomás Herrera.” He stopped beneath a busted streetlamp. Rain jewelled his dark curls. A silver medallion rested against his chest, Saint Christopher worn smooth by thumbs. “Metropolitan Police. Put the bag down.” His gaze travelled over her warrant card, then to the unmarked car behind her. “You followed me from Soho for a chat?” “The bag.” “There’s a patient waiting.” “Then he’ll be glad of the extra time to describe his symptoms.” Herrera’s warm brown eyes hardened. He set one foot back, weight balanced, and Quinn moved to block the mouth of the alley beside him. “Don’t,” she said. He ran the other way. Quinn snatched the radio from her coat as his trainers struck the pavement. Herrera vaulted a stack of delivery crates, clipped the top with the medical bag and landed without breaking stride. Quinn went through the crates. Plastic split under her boot. Something inside them hissed. “Control, Quinn. Foot pursuit, Camden High Street. Male, twenties, dark curly hair, grey coat, carrying a medical bag. Require units.” Herrera cut between a night bus and a delivery van. The bus swallowed him in a wall of spray. Quinn ran along its flank, one hand raised against the mirror as it passed, and caught sight of him again on the far pavement. “Control, what’s the offence?” She ducked under the wing of a roadside sign. “He’s running.” “That’s not an offence, Quinn.” “Get me a unit.” Herrera glanced back. Not winded. Annoyed. He turned into a lane where restaurant waste steamed in metal bins. Quinn followed. Her shoes lost purchase on something soft; she caught a drainpipe and swung herself upright. Ahead, Herrera dragged a wheelie bin into her path. She put both hands on it and shoved. It rolled back at him, forcing him to dodge. For three seconds she gained. He looked over his shoulder again, closer now, close enough for her to see the medallion bouncing against his coat. “Stop making this worse.” “You followed me here.” “You opened the bag, this ends.” “No. You go home, this ends.” He kicked open a side gate. Quinn reached it as it rebounded and took the full weight on her forearm. Pain jumped to her shoulder. She forced through into a service yard hemmed by brick walls. Herrera was already at the far end, hauling himself over a chain-link fence. The medical bag went over first. He followed with one clean pull. Quinn hit the fence at a run. Her fingers found the wire. At forty-one, she no longer vaulted anything without paying for it, but payment came later. She dropped into the adjoining alley, knees flexed, and ran on. The street beyond held shuttered stalls and boards promising cheap phone repairs. Rain ticked against canvas roofs. A group outside a chicken shop saw Herrera coming and parted with the weary coordination of people who had survived other chases. Quinn barged through after him. “Police. Move.” Someone laughed. Herrera crossed the road towards a stretch of construction hoarding. Behind it rose the tiled flank of a disused Tube station, its upper windows bricked up, its roundel reduced to a faded red ghost. A door stood in the hoarding where no door had been a moment before. Quinn’s radio crackled. “Units four minutes out. Confirm your location.” She gave the street name. Herrera reached the station entrance and pulled something from his pocket. It looked like a coin until the light caught its uneven edge. Bone. He pressed it into a depression in the brickwork. The iron gate beside him shuddered. Rust flaked from its bars as it lifted. Quinn slowed. There were no lights beyond the gate. A staircase descended past the reach of the streetlamps, its walls tiled in green. Warm air breathed up from below, carrying candle smoke, wet stone and a sweetness that made her think of a hospital corridor after the flowers had begun to rot. Herrera stepped under the gate. He could have kept going. Instead, he turned. “You can’t come down there.” “Watch me.” “That’s the problem.” The gate began to descend. Quinn stopped at the threshold. Her radio issued a burst of static, then the dispatcher’s voice. “Quinn, wait for units. Acknowledge.” Her thumb rested on the transmit key. Waiting was sound police work. Four minutes for marked cars, another two to establish a cordon. She could photograph the entrance, record Herrera’s direction of travel and preserve the option of doing any of this again with officers at her shoulder. The gate had sunk to chest height. Herrera’s shoes struck the first stair. DS Morris had waited for a search team three years ago. He had stood outside a rented office in Woolwich, following every instruction Quinn had given him, and something had still killed him before the team arrived. The pathologist’s explanations had grown thinner with each question. Morris’s last transmission remained on Quinn’s old laptop: six seconds of static and Morris whispering that the stairs went the wrong way. She had never found a staircase in the building. Quinn looked at her worn leather watch. The second hand jerked past twelve. She photographed the gate, sent the picture with her location and keyed the radio. “Quinn. Suspect has entered the disused station. I’m maintaining observation.” “Wait for units.” The gate reached waist height. Herrera descended another step. “Detective,” he called. “Don’t.” Quinn dropped into a crouch and went under the gate. It struck the ground behind her. The rain vanished. Her radio died mid-word. Herrera had already disappeared around the bend in the stairs. Quinn followed, one hand skimming the tiled wall. The steps descended farther than the station’s street frontage allowed. A sign pointed towards platforms whose names had been chiselled away. Beneath it, someone had written in white pencil: NO TOKEN, NO ENTRY. The gate had been the token’s work. Quinn had used Herrera’s. She put that fact aside with the others that did not fit. Noise rose to meet her. Not the rumble of trains. Voices. Hundreds of them, packed close, arguing and laughing beneath a canopy of rattling metal. She reached the bottom of the stairs and stopped for half a pace. The old ticket hall had become a market. Stalls crowded between the pillars. Others lined the platforms beyond, their awnings sagging over the tracks. Bottles filled a chemist’s cabinet, each containing a blue flame that bent against the glass as Quinn passed. A woman behind a folding table weighed locks of hair on brass scales. Another stall displayed rows of labelled tins: GRAVE SALT, SECOND SIGHT, WOLFSBANE—ASK. Above an arch hung a chalkboard offering memories bought, debts located, questions answered by the hour. Quinn looked for wires beneath the nearest bottle. Bare wood. No battery pack. The flame inside pressed itself flat as her shadow crossed it. Herrera’s grey coat flashed beyond the ticket barriers. “Herrera.” He shoved through a knot of shoppers. A stallholder seized his arm, then recognised him. “Tommy? Back room’s full. Use the platform.” “Move,” Herrera shouted. “Please, move.” The crowd opened for him. It closed for Quinn. She drove her shoulder between two men in oilskins. One caught her coat. “No token.” Quinn showed him the warrant card. “Metropolitan Police.” He examined the crest without releasing her. “That’s not bone.” She twisted her sleeve from his grip and pushed on. Behind her, something shattered. A stallholder began swearing in a language that seemed to come from beneath the floor. Herrera reached the platform edge and jumped onto the tracks. The medical bag knocked against his hip. Quinn followed, landing among old cables and heaps of blackened glass. There were no rails under her boots, only narrow channels filled with rainwater. A stall on the opposite platform sold knives. The blades turned in their rack as she ran past, following her with their points. Quinn kept her eyes on Herrera. He looked back, and for the first time his face held something besides irritation. “Keep to the middle.” “Worried about my safety?” “Yes.” He vaulted onto the far platform. A vendor pulled a curtain aside for him. Letters hung above it on a length of wire: MEDICAL. EXCHANGE. NO REFUNDS. Quinn climbed after him. Hands reached for her from the crowd. She knocked one aside, ducked another and caught the curtain as it fell. Herrera’s medallion gleamed once in the darkness beyond. She tore the curtain open and went through.
