The last train through the station had run twenty-three years ago. Someone had swept the platform that morning. Harlow Quinn stopped at the foot of the service stairs and looked down the long curve of pale tiles. Beyond the police lamps, darkness swallowed the rails. The air smelled of wet stone, old electricity, and something sweeter she couldn’t place. “Council crew?” she asked. DS Patel followed her gaze. “No scheduled works. We checked.” The clean strip ran from the bottom of the stairs to a yellow line painted at the platform edge. Dust lay thick everywhere else, especially beneath the benches and along the tracks. Whoever had swept had done it carefully, and only where people would walk. A man lay on his side six feet from the edge, one arm folded under him. His coat was open. Blood had dried in his close-cropped hair. “Arthur Bell,” Patel said. “Forty-eight. Dealer in antiquities, according to the business cards. No phone, no wallet. We’ve got a possible fall from the old signal gantry. Dr Shah says the head wound could be consistent.” Quinn looked up. The gantry crossed the tracks twelve feet above them, its ironwork furred with rust. “Who found him?” “A woman from the British Museum. Eva Kowalski. Says Bell called her last night, asked her to meet him here. She came at six, found the body, called us.” “Here?” “Apparently they had business.” That covered very little. Quinn stepped around the body, keeping clear of the numbered markers set by the scene examiner. Bell wore an expensive wool coat, cheap black shoes, and trousers with a wet patch at one knee. His shoes were clean. Not polished—clean in the particular way shoes looked after a walk on dry pavement. She crouched. Patel’s interpretation had the virtue of being ordinary. Bell had climbed the gantry, fallen, and someone had taken his valuables. An abandoned station offered privacy for either a deal or a killing. But there was rust on the gantry and none on Bell’s hands. “Has Shah moved him?” “Only to confirm death.” Quinn leaned closer. A small brass compass rested inside Bell’s open palm. Green corrosion marked its casing; protective symbols, or what looked like them, had been scratched around its face. The needle pointed across the platform toward a wall tiled in cream and brown. “Robber missed that,” she said. “Could be worthless.” “Bell didn’t think so.” His fingers had curled around the compass hard enough to leave their shape impressed in his palm. “What’s behind that wall?” “An old staff passage. Bricked up when they closed the station.” Quinn stood and checked her worn leather watch. Seven eighteen. Forensics would want Bell moved soon. She wanted the platform as it was for another five minutes. “Show me where Kowalski is.” They had put her in the former ticket office. Eva Kowalski sat on a folding chair beneath a cracked route map, a worn leather satchel at her feet. Books strained its seams. She had round glasses, curly red hair, and the watchful expression of someone trying not to look at the platform through the open door. She rose when Quinn entered. “Detective Quinn. DS Patel says you work in the museum’s restricted archives.” “I’m a research assistant.” Eva tucked a curl behind her left ear. “Arthur asked me to identify something.” “The compass?” Eva’s green eyes moved past Quinn to Patel. “Did he have it?” “Yes.” “He showed me a photograph. I hadn’t seen the object itself.” “What did you tell him about the photograph?” “That I couldn’t identify it from one picture.” Quinn waited. Eva took off her glasses and wiped them on the hem of her cardigan, though the lenses were clean. “Mr Bell said it came from a private collection,” she added. “Did he say why he wanted to meet in an abandoned Tube station?” “He said no one would bother us.” “That part he got wrong.” Eva put her glasses back on. Her freckles stood out against pale skin. “I know how it sounds.” “You’re not the first person to meet a dealer somewhere peculiar. What time did you arrive?” “About six. Just after.” “And you found him where he is now?” “Yes.” “Did you touch him?” “I checked for a pulse.” “Did you touch the compass?” “No.” Quinn nodded, then looked at the satchel. “Mind if I see the books?” Eva’s hand closed around the strap. “They’re mine.” “I’m asking.” After a moment, she opened it. Two academic hardbacks, a notebook, a pencil case. No obvious blood. No dust from the platform on the satchel’s bottom, either; she had kept it on her shoulder or held it off the floor. Patel’s radio hissed at his hip. He stepped into the corridor to answer it. Quinn said, “You expected him to be alive.” “Of course.” “You brought your research with you.” Eva glanced down at the books. “He wouldn’t say what else he had.” “What else?” Her mouth tightened. For a second Quinn thought she might answer. Then Patel returned. “Doc wants the body released as soon as we’re done with the scene.” “We’re not done,” Quinn said. Back on the platform, the examiner was photographing Bell’s hands. Quinn asked him for a close shot of the left cuff and waited while he took it. The wet patch on Bell’s trouser knee had begun to dry at the edges, leaving a faint tide mark. Beneath it clung a grain of yellow grit. There was no yellow grit on the platform. Its concrete was grey and smooth. She walked toward the tiled wall, following the direction of the compass needle. The swept path narrowed there, ending at what appeared to be a strip of shadow between a tiled pillar and an advertisement board. The poster advertised a theatre production that had closed decades earlier. Its paper was brittle, but one lower corner had been pressed flat by a fresh thumb. Quinn put her light against the gap. Behind the board stood an iron door, painted the same brown as the tile border. No handle on this side. “Patel.” He came over. “I saw the board. Old maintenance access. Sealed.” “Why sweep up to a sealed door?” He looked from the clean floor to the poster. “Someone using it as a shelter?” “Possibly.” She bent. At the foot of the door was a shallow recess where the floor met the frame. Fresh blood had collected in it, dark and tacky. The smear was no wider than the edge of a coat hem. Patel crouched beside her. “Bell was moved.” “From this side or the other?” “If there’s an other side.” Quinn straightened and swept her light over the wall. Scratches ringed a small circular hollow in the iron, almost hidden beneath a flake of paint. A coin slot, perhaps, though too wide and shallow for any coin she knew. More yellow grit was caught in its lower lip. She remembered Bell’s clean shoes and his damp knee. He had knelt somewhere wet and gritty, then walked—or been brought—through the door. The blow to his head might still have come from a fall, but not from the gantry. “Get this photographed,” she said. “And find out who sealed it.” Behind them, Eva said, “They won’t have a record.” Quinn turned. Eva stood several yards away, on the clean strip, with a uniformed constable just behind her. She must have asked to come out. She stared at the door as if it might open. “You know the station?” Quinn asked. “No.” Eva swallowed. “I mean, records from before the closure are incomplete.” “Of this particular door?” “I didn’t say that.” Quinn looked down at Eva’s shoes. Their soles were edged with yellow grit. Patel saw it too. “Miss Kowalski, did you go through here?” “No.” “Then where did you pick that up?” Eva looked at her feet. Her left hand rose toward her ear and stopped halfway. “There’s grit on the stairs.” “There isn’t,” Quinn said. She had watched every step on her way down. “You found Bell at six, called the police, and told them he was on the platform. When were you going to tell us where you’d been before that?” Eva said nothing. The examiner called from beside the body. “Detective? There’s something else in his coat.” Quinn walked back. He had opened the inner pocket for the photographs. Inside lay a small disc of bone, pierced near one edge, its surface worn smooth by handling. A dark thread ran through the hole. “Not his wallet, then,” Patel said. Quinn studied the disc without touching it. Its rim was stained the same yellow as the grit in the door’s recess. Behind her, Eva made a sound—no more than a breath drawn too sharply. “What is it?” Quinn asked. “I don’t know.” For a moment Quinn heard another voice in another tunnel. Morris, three years ago, telling her over the radio that he’d found a way in. By the time she reached him, there had been no doorway where he said there was one. Only a wall, his dropped radio, and a line of wet footprints that ended against the tiles. She pushed the memory aside. Morris was gone. Bell was in front of her. “Photograph the disc in place,” she told the examiner. “Then bag it separately.” A dull click came from behind the advertisement board. Everyone turned. The iron door had shifted inward a fraction, enough for a thread of warm air to reach the platform. With it came that sweet smell again, sharper now: hot sugar over something bitter and metallic. Patel put a hand on his radio. Eva had gone very still. Quinn kept her eyes on the gap. She could hear footsteps beyond it, more than one set, moving away across a floor that sounded tiled. Then a voice called something she couldn’t make out, and the door began to close. “Hold it,” Quinn said. Patel lunged for the edge. Quinn reached it first and drove her shoulder into the iron. It gave an inch. Light showed through—amber light, shifting with the movement of people on the other side. Then the door slammed against her. Quinn staggered back. The painted edge settled flush with the frame, and the platform went quiet. Patel stared at the wall. “That passage isn’t sealed.” “No,” Quinn said. She looked at the compass in Bell’s palm. Its needle still pointed straight at the door.
