Rain needled Soho and turned Dean Street to black glass. Detective Harlow Quinn stood in the mouth of an alley opposite The Raven's Nest and let the runoff drum on her shoulders. The green neon above the entrance bled down the wet brick and pooled in the cracks of the pavement. Through the front window she mapped the interior in slices. Low light. A bar top scarred with rings. Walls papered with old maps and black-and-white photographs, their frames crooked with age. A bookshelf along the rear wall with a seam of darkness behind it. Her left wrist bore a worn leather watch. Water darkened the strap. Twenty-three minutes past midnight. The door swung out. Tomás Herrera stepped under the awning with a duffel slung across his chest. Rain beaded on his short curly dark brown hair and cut tracks down his olive skin. His warm brown eyes swept the street. One hand adjusted the strap. The cuff of his sleeve rode up and exposed a pale scar along his left forearm and the glint of a chain at his throat. Quinn pushed off the wall. "Tomás Herrera!" He froze. "Met Police. I need a word." Herrera stared at her sharp jaw and cropped salt-and-pepper hair plastered to her scalp. His grip shifted on the duffel. "You followed me from St Bart's. That was you by the ambulance bay." Quinn closed the gap. Her boots threw up fans of water. Her stride held military precision, shoulders square, chin level. "I want the names of the people you patched up in that back room." "You want a lot of things." "Don't." He ran. Quinn sprinted after him and her breath tore white in the cold. Herrera vaulted a stack of rubbish bags outside a shuttered deli and hit Greek Street at full pelt. A taxi swerved, horn blaring, headlights smearing across his back. Quinn cut behind the bonnet and kept her eyes on the duffel bouncing against his hip. "Stop!" Her voice cracked off the shopfronts. "If you run I add obstruction!" "You add what you like!" Herrera skidded round the corner onto Shaftesbury Avenue. Rain lashed the theatre marquees and turned the posters to pulp. A crowd spilled from a late show under umbrellas. Herrera shouldered through them. A woman yelped. An umbrella inverted. Quinn held her warrant card high as she ploughed the same channel. "Police! Out of the way!" Her lungs burned. Her brown eyes locked on the Saint Christopher medallion flapping loose from his collar as he pumped his arms. He glanced back. Fear widened his face. He dived for the Underground stairs at Tottenham Court Road. Quinn took the steps three at a time. Water cascaded down the tiled walls. The stink of wet wool and brake dust filled the passage. Barriers beeped. Herrera hurdled one. An alarm shrieked. Quinn flashed her card at the attendant and leapt after him, her knee cracking on the steel on landing. The northbound platform sweated heat. A train roared in, brakes screaming, wind hurling litter. Doors sighed open. Herrera threw himself inside. Quinn wedged her shoulder between the closing doors and forced her way into the carriage. Passengers stared. Herrera backed down the aisle, duffel clutched to his ribs. The train lurched. Quinn grabbed a pole and steadied her stance. Dripping rainwater formed a dark halo on the floor around her boots. "You lost your licence for this. NHS struck you off for unauthorised treatment. Who do you treat now?" "You read my file." "I read the gaps in your file." "What gaps?" "Three kids with chemical burns no A and E logged. A man with a wound that cauterised from the inside. Supernatural patients, Tomás. Your words on the dismissal hearing." Herrera shook his head. Drops flew from his curls. "You have no idea what you chase." "I chased a good man into a morgue three years ago. DS Morris. My partner. No report explained the blood loss. No report explained the scorch marks on his coat. You knew him?" The train braked for Camden Town. Herrera lunged for the doors the second they parted. "Hey!" Quinn elbowed through the crush and hit the platform running. Herrera sprinted for the far end, past the exit signs, past the staff-only door with peeling paint. He produced a key and twisted the lock with practised speed. The door swallowed him. Quinn caught the handle before it latched and slipped into a service corridor. Bare bulbs caged in wire. A slope of concrete slick with seep. The roar of the live tunnels faded behind them. Ahead, a grille hung ajar over a disused passage. Cold air breathed out, thick with incense and copper and damp stone. Herrera dropped through the gap and vanished down a flight of stairs no map claimed. Quinn keyed her radio. Static spat. "Quinn to control. Foot pursuit. Camden Town. Suspect entered service tunnels near the old branch line." "Quinn, hold position. Await backup. Repeat, hold position. Those tunnels are condemned." Quinn stared at the square of darkness. Water tapped her collar and ran down her spine. Her watch ticked against her pulse. "Control, say again last sighting of DS Morris?" "Quinn—" "Three years ago. Camden. Same sector. You logged his radio as garbled. I heard it." Herrera's footsteps echoed below, then stopped. A low murmur rose, voices layered, a market hum under stone. A tang of burnt sugar and iron drifted up. Quinn eased to the grille and peered down. Stone steps descended to a landing choked with cables. Herrera stood before a figure draped in a high-vis jacket turned inside out. The figure extended a palm. Herrera fished in his pocket and produced a small carved bone token and laid it across the offered hand. The figure bit it, nodded, and stepped aside. Beyond them glowed a vaulted space strung with lanterns. Stalls crowded an abandoned platform. Vials smoked. Caged things fluttered. Awnings flapped over crates stencilled with symbols Quinn failed to read. The crowd parted around Herrera as he merged into the light with his duffel. "One bone token. No token, no passage." The gatekeeper's eyes found Quinn in the dark above. "You carry death on you, officer. Same as the last one." Quinn's throat tightened. Rainwater dripped from her hairline into her eyes. Her hand hovered over empty air where backup should have been. Her fingers brushed the worn leather of her watch. "You let Morris through?" "I let lots of people through." "And how many came back?" The gatekeeper smiled with teeth filed to points. "Pay or force. Choose." Quinn drew her baton. The steel telescoped with a snap that rang down the stairwell. Heads turned in the vault below. Herrera looked back and saw her silhouette framed in the grille. Alarm stripped his face bare. "Harlow, don't! You don't know the rules down here!" "You run again and I swear I pull you out in cuffs through that crowd!" Quinn set her boot on the first step.
