The station wasn’t on the map. Quinn checked twice before putting her phone away. Above her, Camden traffic rattled over a manhole cover. Below, a flight of tiled steps descended into warm air that smelled of wet wool, hot copper, and something sweet going rotten. Detective Sergeant Bell waited at the bottom. “You’ll want this,” he said, holding up a disc of bone threaded on black cord. “I’ve got a warrant card.” “They weren’t impressed.” Quinn took the disc. A hole had been drilled through its centre, and the edges were polished by handling. Not costume plastic. She had seen enough bone to recognise it. “Who gave you this?” “The first officer in. Someone handed it to him after he asked where the body was.” “Someone?” “It’s been that sort of evening.” Beyond him stood a ticket barrier with no machinery inside it. A woman in a stained fur coat sat on the gate, knitting with long metal needles. Her bare feet didn’t reach the floor. Quinn showed her the token. The woman looked at it, then at Quinn’s face. “No photographs.” “Police.” “No photographs,” the woman repeated, and moved her knees aside. Quinn went through. The abandoned platform had become a street. Canvas awnings hung from rusted brackets. Lamps burned blue inside glass jars. On one stall, stoppered bottles rocked gently although no train passed and no draught touched Quinn’s cheek. On another, teeth lay sorted into velvet-lined trays. Something under a tarpaulin knocked three times as she walked past. There were people, too. A good many of them. They watched her with the resentful patience of a crowd waiting for the police to finish being inconvenient. “What is this place?” she asked. “Apparently, the Veil Market.” “Apparently?” “That’s what they call it.” “And we’ve never heard of it?” Bell gave her a look. He had been working with her for six months. He knew when a question wasn’t really for him. At the far end of the platform, police tape cordoned off an old station office. A uniformed constable stood outside beside a small red-haired woman clutching a leather satchel. Her glasses had slipped down her nose. She pushed them up, then tucked a curl behind her left ear. “Witness?” Quinn asked. “Eva Kowalski,” Bell said. “Found him.” The office door stood open. Its wired-glass pane was painted black from the inside. Quinn stopped on the threshold. A man sat behind a wooden desk with his head tipped back against the wall. His right hand rested on his thigh. His left lay palm-up on the desk beside a brass compass. There was a small, dark hole beneath his chin and a larger ragged wound high on the back of his head. Blood had spread down the wall behind him. No gun. “Name?” “Silas Venn. Owns the stall outside. Maps, keys, information. According to Kowalski.” “Time?” “She heard the bang at nine seventeen. Came down here, found the door bolted. Got a porter to force it. We were called at nine twenty-six.” Quinn looked at the door frame. Fresh wood showed around a split keeper. The iron bolt remained extended. “Who’s been inside?” “Kowalski. The porter. Two uniforms. Ambulance crew. Me.” “The rest of the market?” “Contained, as much as we can. There’s an exit into a service tunnel. Uniform on that now.” Bell lowered his voice. “Gun’s probably gone with whoever found him. Self-inflicted, then somebody helped themselves. They don’t seem shy about theft.” Quinn studied the dead man’s hands. No obvious blood on the fingers. No weapon nearby. A cup stood on the desk, half full of black liquid. Papers lay beneath a square of glass, apparently intended to keep them flat. “Murder first,” she said. “Other explanations afterwards.” She put on gloves. The room had no window, only a bricked arch in the rear wall and a ventilation grille above the door. Beneath the grille stood a narrow cupboard. The floor was tiled, worn smooth in the centre and dusty around the edges. Quinn leaned close to Venn without touching him. The wound beneath his chin was almost round. No obvious blackening. No tearing from a muzzle pressed against the skin. She would leave conclusions to the pathologist, but a man placing a pistol beneath his own jaw usually left more than a neat hole. His collar was damp. She moved her torch along the blood on the wall. It ran down from the wound, then broke across a horizontal patch of plaster behind his shoulders. The patch was cleaner than the rest of the wall. “Chair’s been moved,” she said. Bell glanced up. “Ambulance crew?” “Ask.” He stepped out. Quinn crouched. Each chair leg had made a short furrow through the dust. They all ran towards the wall. Someone had pushed the chair backwards after Venn stopped moving. She looked under the desk. There was a thick drop of blood between the chair’s original position and its present one. Beside it, a pale semicircle had been scuffed into the grime. A shoe had turned there. Not a suicide, then. Or not merely a suicide. She stood and examined the bricked arch. Its mortar looked old. White powder lay along the base, disturbed in two places, with a broad sweep between them. The sweep ended beneath the desk. Quinn had seen cleaners attempt to tidy around bodies before. Usually it made the scene worse. Here someone had cleaned one strip of wall and one strip of floor, then left the blood untouched. Bell returned. “Ambulance crew say they didn’t shift him.” “Get the porter.” “He’s at the stall. Name’s Rusk.” “And bring Kowalski.” Eva came in reluctantly. Her satchel knocked against the door frame, and she caught it as though something inside might break. Quinn pointed to the compass. Its brass casing had bloomed green around the hinge. Small marks covered the face instead of the familiar points. “His?” Eva nodded. “What is it?” “A Veil Compass.” “What does it do?” Eva glanced at Bell. Quinn waited. “It finds rifts,” Eva said. “Portals. The needle points towards the nearest one.” Bell exhaled through his nose. “Does it.” “It was made by a Shade artisan,” Eva said. “It isn’t a novelty.” “Were you buying it?” Quinn asked. “No. Silas had sent a message to my workplace. I’m a research assistant at the British Museum.” “What did the message say?” “That he had something from a collection I’d been trying to trace.” “Which collection?” Eva’s fingers tightened on the satchel strap. “Items recovered after a death three years ago.” Quinn felt the room contract around her. “Whose death?” “I didn’t know his name until tonight.” “Tell me.” “Morris.” Bell turned towards her. Quinn kept her eyes on Eva. DS Morris had died in a locked cellar in Limehouse. No weapon. No assailant. A wound the pathologist had described, in his first report, as incompatible with the scene. He had removed that phrase from the final version. “What did Venn have?” “A notebook. Silas said there were drawings in it. Routes. Thresholds.” “Did you see it?” “No.” “Did you know Morris?” “No.” “Did you know me?” Eva hesitated. “Yes. Your name was in the file.” Quinn let the silence lengthen until Eva looked away. Then she turned back to the desk. The compass needle pointed towards the bricked arch. She lifted it carefully and moved to the door. The needle swung. Still the arch. She moved to the opposite corner. It swung again. Bell watched her. “Magnet behind the wall,” he said. “Possibly.” Quinn held the compass above the floor. The needle dipped towards the bottom of the arch. “What’s this white powder?” she asked. Eva crouched without stepping closer. “Chalk.” “Why’s it there?” “It closes a threshold. Or keeps it shut, depending on what was drawn.” “Depending?” “There are different seals.” Quinn studied the dust. Not a loose scattering, then. The remnants of a line. “And someone rubbed this one away.” “Yes.” “With a cloth?” “Probably.” Bell folded his arms. “We’re investigating a shooting, Harlow.” She heard the warning beneath the words. He knew about Morris. Everyone who worked with her eventually knew about Morris. “I’m investigating a room,” she said. “The shooting happened somewhere else.” She pointed to Venn’s collar. “Blood has soaked all the way round the back. His head was forward when he bled. He wasn’t sitting like this. And the chair was pushed back afterwards.” “That doesn’t put him outside the room.” “No. The bullet does.” She raised her torch to the wall above his head. The exit wound faced solid brick. There was blood there, but no strike, no loose mortar, no embedded projectile. She checked the floor immediately behind the chair. Nothing. “He was shot with his head bowed,” Quinn said. “Then put here, leaned back, made to look as though he’d done it himself.” “Without a gun.” “Someone intended to supply one. Then Kowalski knocked.” Eva went pale. “I did knock.” “Before you heard the shot?” “No. Afterwards. I was at the stall when I heard it. I came down the passage and knocked. He didn’t answer.” “How long between the shot and you reaching the door?” “Ten seconds. Fifteen.” Quinn looked at Bell. “Not long enough to finish.” A heavy man appeared in the doorway. He wore a railway porter’s coat, though its brass buttons bore no insignia. Grey hair lay slick against his scalp. “You wanted me?” “Rusk?” Quinn said. He nodded. “Show me how you forced the door.” He pointed to a short iron bar leaning outside. “Put that under the bolt housing. Leaned on it.” “On your own?” “Woman watched.” Eva nodded. “Did you enter?” “Only to see if he was breathing.” “Did you touch him?” “No.” “Move the chair?” “No.” Quinn looked at his hands. Broad, clean, with pale scars across the knuckles. There was chalk caught in the seam of his right cuff. “Where were you when you heard the shot?” “End of the platform.” “What were you doing?” “Packing. Market moves at the full moon. Takes time.” “Did you know Mr Venn?” “Everyone knew Silas.” Rusk’s eyes went to the compass in her hand. Not the body. The compass. Quinn lowered it beside her leg. “Empty your pockets.” His jaw worked once. “You need grounds for that.” “Then we’ll start with your name and address.” He reached slowly into his coat and took out a tobacco pouch, a folding knife, three bone tokens, and a handkerchief. The handkerchief was grey with chalk. Bell straightened. “Dusty place,” Rusk said. “Open it,” Quinn told him. A narrow smear of red crossed one corner. Rusk looked towards the passage. Bell moved into the doorway. Quinn set the compass on the desk and caught Rusk’s wrist before his hand reached the knife. He pulled hard. She turned with him, drove his palm against the wall, and folded his arm behind his back. “Don’t.” For a moment he tested her grip. Then his shoulders dropped. Bell cuffed him. “Blood gets about,” Rusk said. His voice had lost its easy weight. “You can’t prove whose.” “No,” Quinn said. “Not here.” That was the important distinction. Suspicion wasn’t proof. Chalk wasn’t proof. A strange compass wasn’t proof. But it was enough to stop him leaving. “Search him properly,” she told Bell. “Keep everything separate.” Bell took Rusk outside. A few seconds later he called her name. In his gloved hand lay a small automatic pistol. Rusk stared past them both. Quinn checked Eva. She had backed against the cupboard, one hand pressed flat over her mouth. “Stay there.” The gun would have to be tested. So would the blood. Quinn wanted photographs of the chair tracks, samples from the wall, casts of the scuff beneath the desk. Ordinary work. Reliable work. She went back to the arch. Behind her, Bell cautioned Rusk. The familiar words steadied the room. Quinn crouched and shone her torch across the remaining chalk. At the left edge of the arch, several short strokes still clung to the mortar. One hooked down, then doubled back. She knew that shape. Morris had drawn it on a receipt the week before he died. She had thought it was a doodle. He had folded the receipt into his wallet, and later she had signed for the wallet with the rest of his effects. “What happens if the line is broken?” she asked Eva. “The threshold opens.” “It looks like brick.” “Yes.” Quinn extended one gloved finger towards the gap in the chalk. “Don’t,” Eva said sharply. “Please. We don’t know where it goes.” Quinn stopped. In the narrow beam of her torch, the bricks seemed solid. She could see chips, mineral stains, a dead spider suspended on a thread. Then air moved across her knuckles. Cold air, carrying the smell of rain and engine oil. She lowered the torch until its beam struck the wall at an angle. The spider vanished. Not moved. Vanished. Beyond where it had hung, she saw a wet concrete floor and the edge of a wooden chair. For several seconds she didn’t breathe. Then she shifted her hand. Brick filled the beam again. She looked down at the chalk on the floor, at the scuffed sweep, at the small drag mark she had taken for a cleaner’s carelessness. Someone had hauled Venn through there. Someone had seated him, pushed him back, gone out, and bolted the office door from inside. Then stepped through a wall and rubbed away enough chalk to keep the route open. Rusk had needed to return as the helpful porter. Break the bolt in front of a witness. Recover whatever he had left unfinished. Quinn rose. “Bell. Nobody touches this wall. Nobody puts a hand through it.” He looked from her to the arch. “Through it?” “Just do it.” She crossed to Rusk. His face had gone slack. “Where’s the notebook?” “I don’t know.” “Silas was going to sell it to her. You came to collect it first.” “You’ve got your gun. Be satisfied.” Quinn studied him. Chalk on the cuff. Blood on the cloth. Three tokens where most people carried loose change. Morris had walked into a cellar with no way out. Or no way out that she had been able to see. For three years she had mistaken the limits of her understanding for the limits of the room. She glanced at her worn watch, then gave Bell the time for his notes. “Seal both exits. Nobody leaves until we have names.” “There are forty people out there.” “Then you’ll need more officers.” Rusk gave a short, humourless laugh. “You think they’ll still be here when your officers arrive?” Quinn stepped closer. “You will.” His gaze flicked towards the office. Towards the wall. She had it now: not a confession, not the whole of it, but the shape of the thing. There was another crime scene beyond those bricks. A bullet to recover. A notebook to find. And for the first time since Morris died, a door she knew enough not to open alone.
