The rat-grey sky wept over Soho. Rain slicked the pavement into a fractured mirror, distorting the lurid greens and reds of the neon signs. Detective Harlow Quinn’s coat, heavy with water, clung to her frame. Ahead, a figure broke from the muted flow of the crowd, his dark curls plastered to his forehead. Tomás Herrera. He glanced back, just a flicker of movement, but his brown eyes locked with hers across the street. The recognition was instant. A spark of panic. He bolted. Quinn pushed off the grimy wall, her worn boots finding purchase on the slick kerb. The chase was on. She vaulted a low barrier separating the pavement from the road, the impact jarring up her spine. A black cab swerved, its horn blaring a furious note into the night's cacophony. She ignored it, her focus narrowed to the back of Herrera's fleeing form. He was fast, weaving through the late-night revellers with a fluid grace that spoke of desperation. He dodged a stumbling couple, sideswiped a stack of overflowing bins, and disappeared down a narrow alley. Quinn followed without hesitation, her breath pluming in the damp air. The alley was a tight channel of brick and filth, the scent of stale beer and decay thick in her throat. Herrera's footsteps echoed off the walls, a frantic, splashing drumbeat. Quinn matched his rhythm, her long strides eating up the ground between them. She saw the scar on his left forearm as he used his hand to brace against a wall for a sharp turn. Her mind catalogued the detail, filing it away with the rest. Former paramedic. Off-the-books doctor to a very particular clique. The kind of people who left behind crime scenes that twisted in her gut and reminded her of Morris. The alley opened onto another street, a chaotic river of headlights and umbrellas. Herrera plunged into it, a ghost in the urban storm. Quinn pushed harder, the muscles in her legs burning. She shoved past a man holding a wilting newspaper over his head, earning a curse she didn't hear. Her world had shrunk to the space between her and Herrera. Nothing else mattered. The leather of her watch was slick against her wrist. It was Morris’s watch. She never took it off. He led her north, through the labyrinthine bleed between Soho and Camden. The streets grew less polished, the buildings taller and more severe. Herrera glanced over his shoulder again, his olive skin pale in the intermittent glare of streetlights. He was flagging. Good. Quinn felt the familiar, cold surge of adrenaline. She could run all night. Her body was a machine honed by eighteen years on the force, by discipline forged in places much worse than this. He ducked left, into the shadow of a railway bridge where the rain hammered onto corrugated iron with a deafening roar. Quinn followed him under, the sudden change in sound a punch to the ears. Graffiti covered every surface in a riot of colour and overlapping text. Herrera scrambled up a short, steep embankment of gravel and dirt, his hands slipping on the wet earth. He clawed his way to the top and vanished over the edge onto the tracks. Quinn swore, the word swallowed by the din. She took the embankment in three powerful strides, her fingers digging into the mud for purchase. She crested the top and landed lightly on the wooden sleepers between the rails. The tracks stretched into the darkness, two silver ribbons gleaming under the faint city glow. Herrera was a hundred yards ahead, a frantic silhouette against the gloom. Her radio crackled on her belt. She ignored it. No backup would get here in time. This was hers. The chase felt primal now. Away from the cars and the people, it was just the two of them, the rain, and the groan of old steel. Her lungs burned. Each breath was a sharp intake of cold, metallic air. Herrera was stumbling more often, his earlier agility worn down by raw fatigue. He risked another look back, his face a mask of exhaustion and terror. He veered off the main line, leaping down onto a service path that ran alongside a disused tunnel mouth. The entrance was a perfect black arch, sealed with a rusted iron gate festooned with chains and dead vines. A dead end. “Nowhere to go, Herrera.” Her voice was raw, cutting through the drumming rain. He didn't answer. He fumbled at the gate, his hands shaking. Quinn slowed her pace, her hand resting on the butt of her service weapon. She advanced cautiously, her footsteps crunching on the loose ballast. This was wrong. The air felt heavy, charged with something other than the storm. It was the same electric tang she remembered from that warehouse. The night Morris died. Herrera wasn't trying to break the lock. He reached into his jacket pocket and pulled out a small, pale object. It looked like a piece of carved bone, milky white in the gloom. He held it up to the centre of the gate, where a circular metal plate was set into the bars. For a moment, nothing happened. Then, a low hum resonated from the gate, and a faint, sickly green light pulsed from the bone in his hand. The chains slithered away from the gate like startled snakes, retracting into the brickwork. With a groan of tortured metal, the gate swung inward, opening onto absolute darkness. Herrera threw one last desperate look at her and plunged inside. The gate swung shut behind him with a final, echoing clang. The chains snaked back into place. Quinn stood frozen, rain plastering her salt-and-pepper hair to her scalp. She stared at the gate, her heart hammering against her ribs. She drew her weapon, the cold weight of the metal familiar in her hand. She approached the gate, pressing her face close to the bars. The air that seeped out was cold and smelled of damp earth, ozone, and something else. Something sweet and cloying, like overripe fruit and funeral flowers. From a street not far away, a siren wailed, a lonely sound that seemed to belong to another world. Her own world. The world of rules and explanations. Behind this gate was something else entirely. The same something that had taken her partner. She could call it in. Report a suspect evading arrest, last seen at a sealed Tube entrance. They would send a unit. They would find nothing. They would log it as another dead end. Another one of Quinn's hunches that went nowhere. Or she could follow him. She could step through that gate and into the place where the shadows had answers. Her radio crackled again, a garbled spit of static and a distant voice. She thumbed the switch, silencing it. The rain fell, relentless, washing the city clean, but it couldn't touch the wrongness of this place. Her knuckles were white where she gripped her pistol. Her jaw was a hard line of defiance. She stared into the suffocating blackness behind the iron bars, the hum of the city a forgotten memory.
