Detective Harlow Quinn reached the bottom of the service stairs and found a ticket barrier bolted across the passage. No trains had used the station beneath Camden for decades. Someone had fitted the barrier with a new steel latch. A constable stood beside it, holding a plastic evidence bag. “Found this in the lock when we came down.” Inside lay a bone disc the size of a ten-pence piece. A hole ran through its centre, and tiny grooves circled one face. “Who opened it?” “I did. Gloves on.” Quinn checked the latch, then stepped through. The constable stayed at his post. Beyond him, electric lanterns lit the platform in hard white patches. Canvas awnings crowded the old tracks. Under them stood tables, crates and empty display racks. Someone had cleared most of the goods but left behind a smell that caught in Quinn’s throat: lamp oil, wet stone, crushed herbs and the copper tang of blood. Her colleague crouched beside the body near the platform edge. Detective Sergeant Nikhil Patel looked up over a strip of scene tape. “Morning, Harlow. Mind the chalk.” Quinn stopped short of a pale circle drawn on the tiles. The victim lay across it, his legs outside the ring and his head within. He wore a dark coat with a row of small inner pockets. Blood had dried beneath his right ear. “What have we got?” “Male, fifty or thereabouts. No identification. Porter found the gate open at six and called it in. Uniforms came down expecting squatters and found him.” Patel stood and pulled off one glove. “Looks like a market for stolen goods. Something went wrong during a deal.” Quinn looked along the platform. Hand-painted signs hung above the abandoned stalls. One read MEMORY REPAIRS. Another offered WINTER APPLES, though no apples remained. A price card beside a stack of empty velvet trays listed six crowns. “Stolen from where?” Patel followed her gaze. “Half this stuff looks like theatre junk. The rest has gone.” A forensic photographer moved around the body. Quinn waited for the flash, then crossed to a stall beside the tiled wall. Dust covered its counter except for six clean squares where boxes had rested. Beneath it sat an abandoned mug. A thin skin had formed over the tea. “They left in a hurry,” Patel called. “Not everyone.” Quinn pointed at the mug. A dark lipstick mark stained its rim. Two stalls down, a small electric kettle still held warm water. Someone had drunk tea after the man on the floor had stopped bleeding. Patel joined her. “Or before he died.” “The porter called at six. What time did he find the gate open?” “Just after. He noticed the latch when he checked the upper passage.” Quinn glanced at the barrier behind them. The constable’s boots showed through its bars. “And the pathologist?” “On his way. Blood feels dry. We’re waiting for him before we put a time on it.” She bent towards the mug without touching it. A crescent of clean wood marked where its handle had rested before someone moved it closer to the edge. A loose thread of red wool clung to a splinter in the counter. “Who moved the cup?” Patel leaned in. “Forensics haven’t reached this stall.” Quinn turned towards the body. Three officers had crossed the platform to get there; their blue overshoes had left faint prints in the dust. She could pick out the porter’s broad work boots near the barrier. None came within a metre of the mug. “Get it photographed before someone decides they need a drink.” Patel waved the photographer over. Quinn walked to the chalk circle. Up close, she saw that someone had drawn it with a single steady stroke, interrupted only where the victim’s coat covered the tiles. The man’s left hand lay palm-up. A green stain crossed the creases of his fingers. His right hand gripped a small brass compass. Patel caught her looking. “A souvenir, most likely. There’s a stall full of them near the stairs.” “This one was in his hand?” “Closed around it. We haven’t shifted him.” Quinn crouched. Verdigris crusted the compass hinge, and tiny marks covered its face. The needle pointed across the platform towards an old advertising recess. The sign inside promoted a summer rail excursion, its smiling family faded almost to ghosts. She checked her worn leather watch. North lay back towards the stairs, give or take the curve of the tunnel. She turned her head to judge the direction again. “Steel down here,” Patel offered. “Rails, wiring, half a century of rubbish.” “Mm.” The victim’s fingernails held grit and a thin strip of blue paper. Blood filled the seams of his coat collar, but little marked his chest. Quinn followed the stain beneath his head. It ran across two tiles, stopped at the chalk line and gathered in the groove beside it. “Did someone draw the circle after the blood spread?” “That’s what it looks like.” “No.” She pointed. “The chalk crosses the groove. The blood stopped before it reached it.” Patel crouched beside her. “A raised edge?” “Feel it.” He pressed a gloved fingertip against the tile. “Nothing.” “Blood on the collar, under the head. None on the upper wall, none on the stall behind him. He fell here, or someone put him here before much came out.” Quinn looked at the chalk on either side of the body. “The person with the chalk stood close enough to reach round him. Where did they put their feet?” Patel studied the floor. “We’ve got prints everywhere.” “Near his head.” He moved his torch across the tiles. Dust showed in the joints, but the space behind the dead man’s shoulders remained clean. A long drag mark ran from the body towards the platform edge. “There,” Patel said. “They pulled him from the tracks.” Quinn followed the mark. It ended at the lip of the platform. Below, old rails disappeared into a black tunnel. A ladder rose from the track bed, and a film of dust lay across every rung. “Not from down there.” She pointed to the ladder. “No marks on it. And that line’s too narrow for his shoulders.” “A crate, then. They moved the stock and dumped him.” “Perhaps.” Patel looked at her. “You haven’t liked a single answer since you got here.” Quinn rose. “I like answers that fit.” She followed the drag mark away from the body. Its edges stayed straight for three metres, then broke where several heel prints cut across it. The line didn’t lead to the barrier. It led towards the advertising recess. A second mark ran beside it, so faint she saw it only when Patel’s torch struck the tiles at an angle. Two narrow tracks, the width of a handcart’s wheels. She pictured a loaded trolley moving across the platform. At the recess, both tracks stopped. “There’s another service door,” Patel said. “Behind the poster, most likely. That’s how they cleared the merchandise.” Quinn faced the recess. The advertisement sat inside a frame of cracked cream tiles. No hinges. No handle. Mortar filled every joint. She pressed her knuckles against the centre and heard a dull, solid knock. “The builders sealed it,” Patel said. “They might have fitted a panel over the front.” “Get someone to check the plans.” “I already asked. Records are pulling them.” The photographer finished at the stall and approached the body. Quinn stepped aside. As he lifted his camera, its strap brushed a brass hook fixed to an awning pole. The hook swung, casting a thin shadow across the floor. Quinn looked at the shadows beneath the other stalls. Every awning along the platform faced the tracks, ready for customers walking between counter and edge. The three nearest the advertisement faced the wall. “Who set those up?” Patel lowered his torch. “What?” “The stalls. The sellers stood with their backs to the tracks.” “People could come through both ends.” “Then where are the marks by the barrier?” Patel looked down the length of the platform. Dust gathered thick beside the stalls nearest the stairs. The clear path ran past the body and ended at the advertising recess. Quinn went back to the victim. She held out her hand to the photographer, and he passed her a clear evidence ruler. Without touching the body, she set it beside the narrow drag mark. Twelve centimetres. The distance between the wheel tracks matched the distance between the legs of a folded display rack nearby, but the rack stood upright and left no trail through the dust. “Any carts down here?” she asked. “Two. Both by the stairs.” “And both too wide.” Patel scanned the stalls. “I can have the team measure the lot.” Quinn looked at the man’s open left hand. The green stain followed the shape of his fingers, as if he had held the compass there first. His right fist had closed over it later. She moved around him, careful to keep clear of the chalk, until the advertising recess lined up with the compass needle. Patel joined her. “You think someone used that thing to find the door?” “I think he held on to it while he died.” The needle remained fixed on the faded family in the poster. Quinn studied their faces, then the blue sky printed behind them. One corner had lifted from the backing. A strip of blue paper showed beneath it, the same shade as the fragment under the victim’s nails. She raised her hand towards the loose corner and stopped. “Photograph this first. Then ask for a ladder.” Patel looked from the poster to the dead man. “For a scrap of paper?” “For whatever he reached.”
