The call had said burglary, one injured suspect, possible weapons. By the time Detective Harlow Quinn reached the old Tube entrance beneath Camden, the injured suspect had become a dead man and the burglary had become a room nobody could explain. A constable stood beside a locked service gate, rain shining on the shoulders of his high-vis jacket. Beyond him, tiled steps descended into darkness. “Who found him?” Quinn asked. “Council maintenance crew. Came to check a report of water in the tunnels. They found the gate open and called it in.” “Was it open when you arrived?” He glanced at the padlock hanging from its chain. “Maintenance locked it after they came back up.” Quinn took the key he offered. The lock was wet on one side, dry beneath the shackle. Fresh scratches scored the painted gatepost. Downstairs, the station smelled of damp stone, hot wiring and something sweeter that had already gone stale. Battery lamps stood at intervals along the platform. Their light picked out the old roundel on the wall, half buried beneath soot and mineral bloom. On the tracks, a shallow film of black water held a trembling reflection of the ceiling. Detective Sergeant Nisha Patel waited near the far end of the platform, blue overshoes bright against the grime. She held a notebook open in one hand. “You’ll want to see the body before they move him,” Patel said. “I’m told it was a burglary.” “I think someone used the place for dealing. He came to collect, there was an argument, and someone put a blade in him.” She looked down the platform. “Possibly more than one someone.” Quinn followed her gaze. Temporary stalls had been assembled along both walls: folding tables, timber crates, lengths of dark cloth strung from exposed pipes. Most had been stripped. One table held an empty velvet-lined case; another, a neat row of unstoppered brown bottles. Beneath a lamp, a chalkboard advertised prices in three currencies Quinn recognised and four she did not. The floor told a livelier story than the abandoned stalls. Mud, spilled powder and hundreds of shoeprints crossed the tiles. Someone had carried away merchandise in a hurry. “You didn’t call uniforms in?” Quinn asked. “Two came down with the maintenance men. I sent them back to the gate. Forensics are on their way.” “Good.” Patel stopped beside a ticket booth whose glass had been painted black from the inside. A man lay in the narrow gap between booth and wall. He was perhaps thirty, dressed in a wool coat too fine for the damp. A knife protruded from his chest. His right hand rested open against the tiles. Quinn crouched without touching him. His shoes were clean along the upper leather, muddy at the soles. There was blood on his shirt, on the knife handle, and in a dark pool beneath his ribs. None marked the wall behind him. Patel turned a page. “No wallet. No phone. Maintenance found him at six forty. The crew supervisor says the station’s been sealed for years. He’s offered to show us the paperwork.” “He needn’t. Someone’s been paying for electricity.” Patel looked up at the working lamps. “The crew says those weren’t here.” “They’re battery-powered. I mean the wiring.” Quinn pointed to a thin cable running above the stalls. Its insulation had been cut neatly, then twisted into the station’s original circuit. “That splice has tape on it. Recent tape.” “Not necessarily recent.” “The tape is still blue.” Patel made a note. Quinn leaned closer to the dead man. His open palm had a pale circular patch in its centre, the size of a ten-pence piece, while the rest of his skin was stained with fine grey dust. Two flecks clung to the web of his thumb. “Did you find anything in his hand?” “No.” “He was holding something.” “His killer took it.” “Maybe.” Quinn stood. “Who moved him?” “No one.” “He didn’t fall here.” Patel glanced at the blood. “He was stabbed and staggered into the gap.” “With the knife still in him? There’s no blood on the wall, and it’s too narrow to miss if he stumbled through. Look at his coat.” A chalky line crossed the back of the man’s left shoulder. At the same height, a smear marked the wall opposite. Not a glancing touch: his coat had dragged along it for nearly a metre. “He was carried,” Patel said. “Or pulled.” Quinn looked at the man’s shoes again. “Soles touched the floor. Heels first, by the marks. Someone brought him in here after he died.” Patel closed her notebook halfway. “That still sounds like a deal gone wrong.” “It might be. Who was here when maintenance came down?” “No one. They heard movement on the platform, but by the time they reached it, the place was empty.” “Which direction?” “Down the east tunnel. That’s where they thought the water leak was.” Quinn took a lamp from its stand and walked toward the tunnel mouth. Its beam slid over torn paper, a smashed bottle and a little white disc lying beside the rail. She crouched. Bone, polished by handling, carved with a shallow notch through its centre. She had seen its likeness in photographs recovered from a Camden flat last month: a set of twelve kept in a biscuit tin, with no buyer or seller willing to say what they were for. “Patel.” Patel came over. Quinn showed her the disc without lifting it. “A gaming counter?” Patel said. “Or admission.” “To what?” Quinn looked back at the stalls. “This.” The east tunnel opened into a section of track screened by a tarpaulin. Behind it stood a makeshift barrier of steel shelving and pallets. Someone had knocked the central pallets aside, leaving a gap just wide enough to pass through. “They ran this way,” Patel said. “Maintenance heard them.” “Perhaps.” Quinn swung the light down. Footprints converged on the opening, muddied at their toes. Past it, she could see only a few more metres of track before the tunnel bent out of sight. She stepped through. Water soaked the edge of her overshoe. On the far side, the dust lay undisturbed. Patel followed. “They could have gone through the water.” “It’s an inch deep. There’s silt on top.” Quinn set the lamp low. A thin skin of grit floated there, intact except where a slow drip struck it from above. “Nobody crossed this way.” “Then they went back over the platform before the crew saw them.” “Possibly. Why break the barrier?” Patel had no answer. Neither did Quinn, yet. She returned to the dead man. From the tunnel mouth, she could see that his coat hem was wet. The drag marks ended three feet short of his body, where the floor became clean tile. Whoever had moved him had lifted him for those last few steps. A crime scene officer arrived with a camera and began photographing the body. Quinn directed her to the drag marks, then went to the nearest stall. The velvet-lined case had a small circular indentation in its centre, flecked green around the rim. Beside it lay a card with one word written in block capitals: COMPASS. Patel read it over her shoulder. “Someone stole the merchandise.” “From a room where everyone else left theirs behind?” “They took what was valuable.” Quinn surveyed the empty tables. “Those bottles were uncorked before anyone knocked them over. And look at the cloth.” A length of fabric hung from a pipe above them, its cut edge straight. Six other lengths around the platform had been taken down in the same way, leaving loops of string tied to the pipes. Traders had packed what they could carry. They hadn’t been robbed. “Something sent them running,” Quinn said. Patel’s gaze returned to the dead man. “Him?” Quinn remembered the open hand, its clean circle. “Maybe what he was carrying.” The crime scene officer waved her closer. “Detective. There’s something beneath his sleeve.” Quinn stepped to the body. The officer eased back the cuff with forceps, exposing a leather strap caught beneath the man’s watchband. A broken thread hung from it. Beside the cuff, half hidden under the coat, was a smear of green. “Photograph it first,” Quinn said. While the camera flashed, she looked at her own worn leather watch. Six fifty-eight. The dead man’s watch, an expensive steel model, had stopped at 6:12. Its glass was unbroken. Water had seeped under the face. “Maintenance heard movement at six forty,” Patel said. “If that watch stopped when he got wet—” “He was wet before they arrived.” Quinn pointed to the hem. “But the platform floor is dry here. The east tunnel water’s black with silt. His coat’s wet with clean water.” Patel looked toward the tracks. “Where would he get clean water?” Quinn turned slowly, following the cable above the stalls to a maintenance door set into the wall. The paint on its handle was worn bright. Beneath it, a narrow tide mark ran along the tiles and vanished under a mat laid in front of the door. She lifted the edge of the mat. The tiles beneath were wet. “Here.” The door opened onto an old staff washroom. A tap stood over a deep porcelain sink, its basin clean except for one dark drop near the drain. Water shone on the floor. Someone had wiped down the counter but missed the underside of its lip, where a thin reddish line remained. Patel leaned in. “They cleaned up after moving him.” “Before. Look at the floor.” The wet shoeprints ran out of the washroom toward the booth. At the threshold, the first print was sharp enough to show a crescent cut in the heel. Each successive print grew fainter. Quinn had seen the same cut at the edge of the dead man’s left shoe. He had walked out of the washroom. “He went in there alive,” Quinn said. “With blood on him.” “Then someone stabbed him at the sink?” “The knife’s in his chest. You’d expect blood in the basin if they stabbed him here and washed up. There’s barely any.” She examined the faucet. Grey dust had settled around its base, except for a clean oval where an object had rested. A green stain marked one edge. The compass. The man had put it beside the sink, then taken it up again. Quinn went back to his body. The knife had entered below his breastbone, its handle angled toward his right shoulder. His shirt was cut around the blade, but the wool coat was not. “He was stabbed before he put his coat on,” she said. Patel stared at her. “Why would he put his coat on with a knife in him?” “He wouldn’t.” Quinn crouched. The coat was buttoned wrong: the lowest button strained in the second-lowest hole. The man’s shirt collar had been pulled crooked, and one lapel covered part of the knife handle. Someone had dressed him after the stabbing. The coat hem had got wet when they dragged him out of the washroom. “He bled here, then,” Patel said. “They moved him, dressed him, and tried to make it look as if he’d been stabbed in the booth.” “Why?” The question sat between them. Quinn looked at the narrow gap, the open palm, the clean circle where something round had rested. Someone had placed an object in the man’s hand after they brought him here. Later, someone had taken it. She searched the tiles around the body. A faint line of pale dust ran from his fingertips toward the ticket booth door. It ended beneath the door’s metal sill. Quinn asked the crime scene officer to photograph the line. Then she pulled on fresh gloves and opened the booth. Inside, the counter was bare except for a cracked fare ledger. At floor level, an old return slot had been cut into the wall. The metal flap hung loose. She put her lamp close. Behind the flap, something brass caught the light. “Don’t touch it,” Patel said. “I won’t.” The officer photographed it in place, then drew it out with padded forceps. It was a small brass compass with verdigris in its seams. Protective sigils had been etched around the face in lines too fine to read without magnification. The needle swung once, twice, and settled—not north, but toward the tiled wall behind Quinn. Patel watched it. “Magnet in the wall.” “Could be.” The officer carried it a few steps down the platform. The needle held its angle toward the same stretch of tile. Quinn followed its point to an old advertising panel. Its glass had been painted over. The frame sat flush at the top and stood proud at the bottom, where fresh mortar dust had gathered in a white ridge. Patel tried the panel’s edge. It moved beneath her fingers. “Wait for the photographer,” Quinn said. Patel withdrew her hand. They both stepped back while the officer documented the frame. Then Quinn eased it open. Behind the panel was no passage. A bricked recess held a square of black glass, roughly the size of a lift mirror. Quinn’s lamp made a hard white spot on its surface. She shifted the beam and saw the platform reflected behind her: the stalls, the lights, Patel standing at her shoulder. In the glass, the ticket booth door was open. The dead man was not there. Quinn turned. He lay exactly where they had left him, the officer kneeling beside him. The glass reflected the officer too, down to the camera strap at her neck. It simply omitted the body. Patel said nothing. Quinn held the lamp steady, though the worn leather of her watch strap had gone tight against her wrist. Three years earlier, DS Morris had vanished from a locked interview room. The video showed him going in and never coming out. Quinn had spent months proving that cameras could fail, doors could be forced, witnesses could lie. None of it had brought him back. The compass needle pointed into the glass. A sound came from the other side: a single, patient knock. Quinn lowered the lamp just enough to see her own reflection. Its mouth was closed. So was Patel’s. “Get everyone upstairs,” Quinn said. “Now.” Patel hesitated only long enough to look at the body once more. Then she called to the crime scene officer. Quinn stayed by the open panel. The market had emptied through a passage nobody could find. The man had reached the washroom alive and had been killed after he came out. Someone had dressed him, dragged him to the booth and put the compass in his hand. He had dropped it through the return slot—or someone had hidden it there for him. The glass showed her a vacant platform. In its reflection, the ticket booth door began to close. Quinn stepped aside. Behind her, the real door remained open.
