Rain flattened the city into black glass. It slicked the pavements, ran in bright threads down shopfronts, and turned the traffic lights into smears of red and green. Detective Harlow Quinn kept her eyes on the man ahead. He had a narrow build and a grey coat that snapped behind him as he ran. One hand clutched a canvas satchel against his ribs. The other swung out for balance as he cut between a taxi and a delivery van, boots skidding over the painted lines. “Police! Stop!” He glanced back. The streetlamp caught a pale slash of his face, then he vanished into the next alley. Quinn reached the crossing as a bus groaned past, its tyres sending a sheet of water across her trousers. She didn’t wait for the signal. She ducked behind the bus, took two strides into the road, and jumped the gutter on the far side. A horn blared. Someone shouted. The grey coat flashed between two bins. Her left wrist struck the brick wall as she rounded the corner. The worn leather watch bit into her skin. She kept moving. The alley narrowed between a shuttered restaurant and a row of brick backs. Water dripped from fire escapes and rattled in a drainpipe. The suspect slipped on a patch of moss, caught himself on a metal door, and drove his shoulder into it. The door gave. Quinn reached it as it swung shut. A square of yellow light remained beneath the frame. She took her pistol from its holster and listened. A hiss of machinery. Footsteps descending. She pushed through. The stairs were steep and tiled, the sort that led to a basement kitchen or a cellar. A bulb buzzed overhead. At the landing, the suspect had left a smear of blood on the rail. Quinn touched it with her thumb, then raised her weapon and went down. “You’re bleeding,” she called. “That bag’s not worth your life.” His answer came from below, a burst of laughter swallowed by the stairwell. The steps ended at a narrow service corridor. Pipes crossed the ceiling. At the far end, a second door stood open on a room that smelled of wet stone, old dust and something sharp, like pennies left in vinegar. Beyond it, a vaulted space spread under the city. Quinn stopped at the threshold. The market filled an abandoned Tube station. Stalls crowded the platform where tracks had once run; canvas awnings and hanging lanterns hid the stained tiled walls. People moved between them in coats, masks and clothes Quinn couldn’t place in any decade. A woman with glassy silver eyes sold little bottles from a wooden tray. At the next stall, a man in a butcher’s apron displayed a row of teeth on velvet. No one looked surprised to see her. The suspect pushed through the crowd, shoulder-checking a stallholder. A stack of black boxes clattered to the ground. People cursed and scattered aside, but none reached for him. Quinn lowered her weapon enough to keep it from sweeping across the crowd, then stepped onto the platform. “Police! Clear the way!” A few people glanced at the badge clipped inside her coat. Most watched the suspect. He reached the opposite side of the station and vaulted over a low barrier. A narrow passage opened beyond it, framed in old white tile. He disappeared into the dark. Quinn took three quick steps after him. A hand caught her sleeve. “Don’t go down there with a gun.” The woman who held her wore a brown leather apron over a red dress. Her fingers were stained blue to the nails. She stood close enough that Quinn could smell smoke on her breath. “Let go.” “You want him, take him in the open. Down there, the market won’t hear your warrant.” “Who is he?” “Someone who bought something he couldn’t afford.” The woman released her. Quinn kept her eyes on the passage. “What’s in the satchel?” “That’s between him and the people he stole from.” Quinn turned the badge towards her. “Harlow Quinn, Metropolitan Police. Move.” The woman glanced at the badge, then at Quinn’s face. Her eyes settled on the sharp line of Quinn’s jaw. “Metropolitan Police don’t come down here.” “Tonight they do.” A laugh sounded from somewhere among the stalls. It held no humour. Quinn looked back. The crowd had closed around the disturbance. A boy gathered the fallen boxes. The stallholder whose goods had been knocked aside counted each one, lips moving. Beyond them, the entry stairs stood bare and bright. The way back remained open. Her radio clicked. “Quinn, status?” The voice broke under static. “We’ve got your last location. Do you have eyes on the suspect?” She pressed the transmit button. “Suspect entered an underground structure. I’m in pursuit.” The radio gave a thin pop, then silence. She tried again. Nothing. A man behind a stall tapped a tuning fork against a glass. The note ran through the chamber, clear and high. The radio spat another crackle. The woman in the apron tilted her head. “It won’t work here.” Quinn stared at the passage. The suspect had bloodied his hand on the rail, but he had not slowed. The satchel might hold a weapon. It might hold stolen property. It might hold nothing but leverage. She had no warrant that would mean anything to the people beneath Camden, no backup, and no knowledge of what waited past the tiled arch. The case had already put one partner in the ground. The thought arrived without warning, hard as a fist. Quinn’s jaw tightened. She saw Morris’s shoulder against a wet wall, his hand lifted to tell her to stay back. Then the memory broke apart, leaving only the sting of rain on her face and the watch digging into her wrist. She thumbed the strap once, then holstered her pistol. The woman’s brows rose. “You’re going after him unarmed?” “I’m going after him with my hands free.” “Those aren’t the same thing.” “No.” Quinn stepped over the barrier. The passage smelled of damp earth. Tile gave way to rough brick, then to old concrete. A string of amber lamps ran along the ceiling, spaced far apart. Their light exposed fresh bootprints in the dust and a thin trail of blood. She followed. At the first bend, she found a paper charm stuck to the wall. Its ink had bled in the wet, the strokes forming a knot of black lines. Quinn reached towards it, then stopped. A low hum pressed against her teeth. She stepped around the paper. “Detective.” Tomás Herrera stood at the next junction, half-hidden behind a stack of crates. Short curls clung to his forehead. A Saint Christopher medallion rested against his shirt, its chain dark with rain. He wore a medic’s bag across one shoulder. A pale scar tracked his left forearm. “What are you doing here?” Quinn asked. “Making sure no one dies on the floor.” “Are you working for the suspect?” “I’m working for whoever gets cut open.” He glanced at the blood on the wall. “He went left.” Quinn studied him. “You know him?” “I know the coat. Not the man.” “Then you won’t mind coming back with me.” “I’ve got a patient.” “You’re not a licensed paramedic.” “Still got hands.” A metallic bang rang out from the left-hand tunnel. Quinn turned towards it. Herrera took one step into her path. “That corridor leads into a warding line.” “Move.” “You cross it carrying iron, and every door down there shuts.” She looked at his hands. The right held a pair of scissors. The left held a roll of gauze. Neither looked capable of stopping her. “Does it shut on him too?” “He knows where it is.” A second bang came from the tunnel, then the scrape of something dragged across stone. Quinn could hear the suspect breathing beyond the bend. She pushed past Herrera. He caught her elbow. She twisted free and pinned his wrist against the wall. “Touch me again and I’ll put you on the ground.” His gaze held steady. “You won’t have time to get him if you walk into that line.” The corridor behind him remained dark. Ahead, the amber lamps flickered once. The trail of blood crossed the floor and vanished beneath an iron grille set into the brick. Quinn lowered her voice. “Tell me what the line does.” “It marks the boundary of the market. Beyond it, the owners decide who passes.” “Owners.” “People with more patience than you.” A figure moved in the shadows behind him. Quinn shifted her weight, ready to draw, but the shape did not come closer. Herrera followed her gaze. “Market watchers,” he said. “They don’t care about your badge.” “They care about the man I’m chasing?” “They care about what he took.” “What did he take?” Herrera’s mouth tightened. “A bone token.” The word meant nothing to Quinn. “A key?” “A way in. A way out.” “Why would he steal one?” “Because he wanted to leave.” The suspect struck the grille from the other side. The iron rang. A breathless curse followed. Quinn looked from the tunnel to the market junction behind her. She could retreat to the station platform, find the woman with the apron, and demand answers from someone on her own ground. Or she could cross into the passage, where her radio had failed and the people waiting in the dark had already decided she didn’t belong. She flexed her left hand. Rainwater dripped from her coat cuff. The leather watch pressed against the bones of her wrist. “Is there another way through?” she asked. Herrera pointed to a narrow stair behind the crates. “It comes out past the grille.” “Then take me there.” “That’s not what I said.” Quinn stepped towards the stair. “You can come with me or stay out of my way.” Herrera slung the medic’s bag higher on his shoulder. “I’m coming. If he’s bleeding, I want to see where.” “Stay behind me.” “You’ll need to keep up.” He took the stairs two at a time. Quinn followed, leaving the warding line and the dead radio behind. The concrete steps climbed through a passage so narrow her shoulders brushed both walls. At the top, Herrera paused beside a wooden hatch and listened. From beyond it came a sharp scrape, then a muffled thud. “Was that him?” Quinn whispered. “Unless the market started moving furniture.” She raised one hand for silence. The hatch had no handle, only a circle of shallow cuts around its centre. She tested the edge. It did not move. Herrera reached into his shirt and drew out the medallion. He pressed it against the cuts. The wood gave a small click. Quinn looked at the pendant, then at him. “Don’t make a thing of it.” “Wasn’t planning to.” He pushed the hatch open. A cold draft swept down the stairwell. Beyond lay another corridor, tiled in the green and cream pattern of an old station. At the far end, a figure stumbled into view with the canvas satchel clutched beneath one arm. The suspect stopped when he saw Quinn. She moved into the corridor, hands spread, blocking the stairwell behind her. “Drop the bag.” His eyes flicked to Herrera, then back to Quinn. Blood ran from his knuckles and darkened the satchel’s strap. “Not a chance.” “Then put it down and tell me what’s inside.” “You don’t want to know.” “I’ve heard that before.” The suspect edged towards a doorway on his left. Quinn matched him step for step, keeping the space between them narrow. “Take another step and I’ll—” “Don’t finish that sentence,” she said. “You’re out of street, out of exits and out of time.” Behind her, Herrera’s bag buckle clicked as he opened it. The suspect tightened his grip on the satchel. His back pressed to the tiled wall. Quinn planted her boots on the damp floor and kept both hands where he could see them.
