Detective Harlow Quinn reached the bottom of the station stairs with grit in her teeth and the sound of a generator rattling somewhere below. A patrol officer stood beside a rusted ticket gate, holding up the cordon tape so she could pass. Beyond him, an enamel sign announced CAMDEN SOUTH in letters the Underground had stopped using decades ago. “How long has the body been here?” “Found at half five. Station staff called it in.” “There are no station staff.” The officer glanced down the stairs behind her. “The people doing the survey, ma’am. They were checking the foundations.” Quinn crossed the gate. Her shoes clicked over loose mosaic tiles. The station smelled of damp concrete, hot dust from the floodlights, and something sweeter beneath it: burnt sugar, or candle wax. On the platform, a photographer crouched beside a man in a grey coat. The man lay on his back near an old advertising wall, one arm stretched above his head. Blood had soaked through his shirt and spread beneath his shoulder. A row of empty trestle tables stood against the opposite wall. Each carried a scrap of coloured cloth, and one held a cluster of candle stubs fused to the wood. DS Malik waited beside the tables, his notebook open. “Welcome to the strangest car boot sale in London.” Quinn stopped short of the body. Her worn watch brushed her coat cuff as she folded her arms. “You’ve spoken to the survey crew?” “Three of them. They came down through the service entrance at five twenty-eight. Found him like this. Nobody saw anyone leave.” “And the tables?” “Unlicensed market. Sellers cleared out when something went wrong.” Malik pointed his pen towards a staircase at the far end. “We found blood on the steps. One of them stabbed him, ran up there.” Quinn looked at the staircase. The first six steps shone with water. A slow leak dripped from a pipe above them and struck the same tread, over and over. “How much blood?” “One print. Partial shoe. Forensics are on it.” She walked round the body without crossing the markers. The man’s coat hung open. Its right lapel had folded beneath him, and a narrow wound showed through his shirt below the collarbone. His eyes faced the tiled wall. Dried blood darkened two fingers of his left hand. His right hand held a small disc, pale against his skin. “Age?” “Forties, give or take. No wallet. No phone.” “What’s in his hand?” Malik checked his notes. “Bone, according to the photographer. Hasn’t been collected yet.” The disc had a hole through its centre. Someone had carved three short lines along one edge, deep enough to catch shadow. “Robbery seems thin if they left anything worth taking.” Malik tilted his head towards the tables. “Depends what they were selling.” Quinn followed his gaze. An open wooden case held a velvet depression the size of a pocket watch. Dust outlined where its contents had rested. At the next table, torn brown paper bore a grease-pencil price: TWO FOR A MEMORY. Someone had scored out MEMORY and written NAME beneath it. “Student performance art?” Malik offered. “Under a station with no public entrance?” “That’s why it’s unlicensed.” Quinn crouched beside the victim. The photographer lowered his camera and shifted back to give her a clear view. A fine line of pale grit marked the man’s coat sleeve. The grit lay across a broad smear of blood, not beneath it. She looked at his shoes. Both soles carried dry grey dust in their grooves. “Platform’s wet.” “Pipe’s been leaking since the place shut,” Malik answered. “Could’ve walked round it.” “Everywhere?” The damp reached from the track edge to the wall. Her own shoes left dark prints where dust met water. The victim’s shoes had left none that she could see. At the ticket gate, a voice rose over the generator. “I told them I knew him. You can’t keep asking me to wait up there.” Quinn stood. A young woman had come past the patrol officer, clutching the strap of a worn leather satchel. Curly red hair sprang loose around round glasses. She tucked it behind her left ear as she took in the body, the cameras, the blood. Malik moved to intercept her. “Miss Kowalski. We’ve got your details. You need to stay behind the tape.” “I gave him a name to ask for. If that’s him, I need to see his face.” Quinn stepped between them. “You can look from here. Don’t come closer.” The woman fixed on the man’s grey coat. Her fingers tightened around the satchel strap. “That’s Daniel.” “You knew him as Daniel what?” “I didn’t. He contacted me at work. I was meant to meet him here this morning.” “Where do you work?” “The British Museum. Restricted archives.” Eva Kowalski swallowed. “He said he had an object I could identify.” Malik closed his notebook against his palm. “And you came to an abandoned station?” “He gave me an address on Chalk Farm Road. I found the entrance after the police cars arrived.” “What object?” Quinn asked. Eva looked past her at the wooden case, then at the man’s hand. “I don’t know. He wouldn’t put it in writing.” Quinn watched her gaze settle on the bone disc. Eva drew her satchel closer. “You recognise that?” “No.” The answer came before Quinn had finished speaking. Eva adjusted her glasses and looked at the floor. Malik held out an arm towards the stairs. “Up you go. We’ll speak to you when we’ve finished here.” Eva let the patrol officer guide her back to the gate. Quinn turned to the wall the dead man faced. Old tiles framed an advertisement for soap, its painted family smiling through hairline cracks. At first glance the blood beside it looked like a handprint left by someone bracing themselves. Four streaks ran across the blue border. “Who examined this?” “Photographed it. No usable prints visible.” Malik joined her. “Victim put his hand out after the stabbing. Fell backwards.” Quinn held her own hand beside the marks without touching them. The streaks lay at shoulder height for the dead man. Each one ran towards the smiling family, but the beads at their ends had collected along the side of the streaks, against the direction gravity should have pulled them. “Get me the first photograph of this wall.” The photographer scrolled through his camera and held up the screen. Quinn compared the image with the tiles in front of her. Nothing had changed since the scene team arrived. A bead of blood sat in a grout line, round and thick, while another had dried in a hook against the edge of a tile. “Could the platform slope?” Malik asked. “Not enough for blood to climb a wall.” She moved along the advertisement. Its bottom edge met a band of black tiles. Most grout lines held decades of grime. One line had no grime at all. A pale grain of mortar clung to it. Quinn followed the clean line upward, around the advertisement and down its far side. Malik leaned in. “Maintenance panel.” “Where’s the handle?” “Painted over. Could be a hatch for wiring.” Quinn stepped back. The entire advertisement sat inside that narrow clean border. At floor level, a curved scratch crossed the wet dust. It began beneath the left corner of the frame and swept out towards the victim’s shoulder. A second scratch ran beside it, packed with pale grit like the grit on his sleeve. “He wasn’t stabbed here,” she said. Malik looked down at the pool beneath the man. “There’s enough blood to fill a bucket.” “Blood from the wound soaked his shirt. It ran out when someone put him down. Look at his shoes.” Malik crouched, keeping his hands clear of the body. “Dust.” “No wet prints leading in. No drag mark across the platform. His coat picked up grit on top of the blood, along that sleeve. He came through the wall after he was hurt.” Malik rose and studied the advertisement. He reached towards the edge, then stopped when Quinn caught his wrist. “Don’t touch it.” “It’s tile, Quinn.” A brass glint caught her eye beneath the nearest table. She crouched and found a small compass lodged against one leg, its casing green with verdigris. Protective-looking marks covered the face. Its needle pointed towards the advertisement. Quinn left it where it lay. “Photograph that too.” Malik peered over her shoulder. “A compass?” “I can see that.” “North’s behind us.” Quinn checked the compass against the direction of the stairs, then shifted her position to look at it from another angle. The needle held on the wall. A fresh nick shone through the corrosion on the casing; someone had struck it against something hard. She stood and returned to the blood marks. One of the victim’s stained fingertips fitted the lowest streak, but his hand had not come to rest anywhere near the wall. He had touched it while he still stood. “The panel moved,” Quinn said. “Those drops ran down when it faced another direction. Then someone turned it back.” Malik’s eyes moved from the dried beads to the clean grout and the scratches at their feet. The generator coughed; in the gap before it caught again, Quinn heard air hiss through the narrow seam beside the soap advertisement. Malik lifted his radio. “Scene team, hold your positions. Nobody uses the far stairs. I want the wall documented from top to bottom.” Quinn took one pace back so the photographer could get past her. She pointed to the clean grout, then to the curved marks in the dust. “Start there. I want every inch of that seam before anyone opens it.”
