The constable at the foot of the stairs held out a tray of bone tokens and would not let Detective Quinn past without one. “They told me it was the rule, ma’am.” “They being?” The constable glanced over his shoulder. Beyond him, a tiled passage descended into darkness. Someone had strung a line of yellow bulbs along the ceiling, but the light did little for his expression. “The people who found the body.” Quinn selected a token. It was warm and roughly oval, with a notch cut into one edge. She held it up to the light. “Animal?” “I didn’t ask.” At the entrance to the passage, an elderly woman sat behind a folding table. She wore a purple dressing gown and a pair of rubber gloves. Quinn showed her the token. The woman examined it, then nodded toward the passage. “Keep it with you.” “Is that all?” “For coming in.” Quinn slipped the token into her coat pocket and continued down. The passage opened onto an abandoned Underground platform, its old station name painted over so many times that only the first black letter showed through. Stalls crowded the platform edge beneath the low iron roof. Most had shutters drawn or cloths thrown over their wares. A few traders remained, watching the police with the deliberate stillness of people who had decided not to be helpful. The air smelled of damp brick, hot metal and something sweet enough to make Quinn’s teeth ache. DS Patel waited beside a cordon of blue-and-white tape. He had taken off his jacket and rolled his shirtsleeves neatly to the elbows. A paper cup rested on the floor beside him, untouched. “Sir,” he said. Quinn ducked under the tape. “What have we got?” “Male, approximately sixty. Name given as Elias Venn. Sold clocks, instruments, that sort of thing.” Patel gestured toward a stall enclosed by wire mesh. “Found by his neighbour at six twenty. Ambulance crew pronounced him.” Inside the enclosure, Venn lay on his back between a workbench and a narrow counter. His grey hair was spread across the boards, and his shirt was dark with blood beneath the left collarbone. A brass instrument lay in his open right hand. A padlock hung from the mesh door. It was closed, though the door itself stood open. “Who opened it?” Quinn asked. “His neighbour. A woman called Lark. She says she cut through the mesh.” There was a ragged hole in the wire beside the latch, large enough for a hand. The cut ends curled outward. “And then?” “She reached through, took the keys from the victim’s pocket and opened the padlock.” “Why not leave the lock and call us?” “She says she thought he might still be alive.” Quinn looked at the blood on Venn’s shirt. “Was there any reason she shouldn’t?” “Not that I can see.” Two crime-scene investigators were working on the platform. One photographed the outside of the cage; the other knelt near Venn’s feet, arranging numbered markers. Quinn waited until the photographer had finished, then stepped closer to the door. The wire around the hole was bright where it had been cut. A pair of heavy shears lay on the counter inside, their handles red. “Lark’s?” Quinn asked. “Venn’s. She says she borrowed them from him yesterday and brought them back this morning.” “Convenient.” “Yes, sir.” Patel glanced at his notes. “She says the stall was locked when she arrived. She saw him on the floor, called for help, then cut her way in.” “Witnesses?” “Three heard her shout. One saw her cutting the wire. Nobody saw anyone leave the stall.” Quinn crouched near the door without touching it. The padlock was an ordinary brass model, its shackle thick and scratched. The latch consisted of two iron loops, one fixed to the door and one to the frame. “You can close this without the key,” she said. Patel looked down. “Yes.” “So the key in his pocket tells us nothing about who locked him in.” “It tells us he didn’t unlock it and let himself out.” “He’s still here.” Patel gave her a patient look. “The traders are calling it a locked-room murder. I’m trying to establish what happened, not make it sound interesting.” Quinn stood. “What do you think happened?” “Someone came in while Venn was setting up, stabbed him and pulled the door shut behind them. Lark found him. The hole and the keys are exactly what they appear to be.” “Any idea who?” “Lark says a young woman was arguing with him last night. Red hair, glasses, carrying a leather satchel. We’ve got her upstairs.” “Why upstairs?” “She tried to leave when she saw the uniforms.” “People do.” “She also had blood on her cuff.” The investigator at Venn’s feet looked up. “We’re ready for you now, ma’am. Mind the markers.” Quinn stepped inside. Venn’s workbench was crowded with small drawers, coils of wire and opened cases lined with faded velvet. One drawer hung partly out. Its brass handle had been twisted sideways, and several shallow gouges marked the wood around it. “Anything missing?” Quinn asked. “Lark says Venn kept cash in there,” Patel said. “Drawer’s empty.” The boards beside the bench were littered with minute brass filings. Quinn followed them with her eyes. They stopped abruptly beneath a rectangular patch of clean wood. “Was something there?” “We don’t know.” The patch was about the size of a large book. At one corner, a crescent of dark wax clung to the floor. The investigator had placed a marker beside it. Venn’s right hand lay palm upward. The object in it was a small brass compass, green with verdigris. Protective-looking marks had been etched around its face. Its needle pointed toward the back of the stall, almost parallel with the platform wall. “Has that been moved?” Quinn asked. “No,” the investigator said. “Photographed in situ.” There was dried blood along the side of Venn’s hand, but not on the compass. His fingers curled loosely around its edge. Quinn leaned closer. The skin beneath the instrument was pale and unmarked. “Can you lift it?” The investigator put on fresh gloves and carefully removed the compass. A narrow streak of blood crossed Venn’s palm where the rim had rested. Quinn looked at the underside. Clean. “Someone put it there after the blood dried,” she said. Patel crouched beside her. “Or he picked it up before he was stabbed.” “Then the rim would have blood on it. His hand was already wet when he closed it around the compass.” “Maybe he held it carefully.” “With a wound in his chest?” Patel considered the body. “All right. Someone placed it there. Why?” Quinn looked at the instrument’s face. The needle had shifted while the investigator lifted it, then settled again, pointing past the workbench. “To tell us something,” she said. “Or to make us think he was telling us something.” A voice behind them said, “It points to the nearest opening.” Quinn turned. A young woman stood beyond the cordon with a uniformed constable. Her curly red hair had escaped from a clip, and one lens of her round glasses was smeared. She had a worn leather satchel clutched against her ribs. Patel rose. “Miss Kowalski, I told you to wait.” “I know. I could see what you were holding.” She tucked a curl behind her left ear. “Please don’t turn it any farther. The needle can stick.” Quinn stepped out of the stall. “You know Venn?” “Eva Kowalski. Yes. I bought things from him.” “Patel tells me you argued last night.” “We argued about an instrument he sold me. It wasn’t what he said it was.” Eva’s green eyes flicked toward the body. “Is he really dead?” “Yes. Where did the blood on your cuff come from?” Eva held out her sleeve. A rust-coloured smear marked the edge. “A book. I caught my hand on the clasp this morning.” She turned her palm over. A small cut crossed the base of her thumb. Patel said, “We’ll check it.” “You said the compass points to an opening,” Quinn said. “A rift. Or a portal.” “Meaning?” Eva hesitated. “Somewhere you can cross from one place to another.” Quinn glanced back at the instrument. “It’s a compass. North is an excellent place to start.” “It doesn’t point north.” “We’ll check that too. Why did you try to leave?” “Because I work in a restricted archive, and I didn’t want my name attached to this place.” Eva swallowed. “I didn’t hurt him.” “Did you come here this morning to see him?” “Yes. I wanted my money back.” “What time?” “Just after six. His shutter was down, so I went to get tea. When I came back, there were people shouting.” Quinn studied the compass again. The investigator held it level now, and the needle pointed toward the back wall. Quinn took her own phone from her pocket and opened its compass. North lay in the opposite direction. “Could there be a magnet behind the wall?” she asked. “There could,” Eva said. “But that isn’t what’s making it move.” “Is there a door behind the wall?” “Not one I’ve seen.” Patel folded his arms. “Sir, if Miss Kowalski was here at six, she had an opportunity. Venn’s neighbour says they argued. There’s blood on her sleeve. We should get her statement somewhere quieter and establish her movements.” “We should,” Quinn said. “First, I want to speak to the neighbour.” Lark’s stall stood on the other side of the cordon. She sold candles from shallow wooden trays: black, white, red, and a deep blue that looked almost purple under the bulbs. She had a long face, a grey plait and the pinched, indignant expression of a woman whose morning had been ruined by other people’s incompetence. “I’ve already told him everything,” she said when Patel brought Quinn over. “I need you to tell me again.” Lark’s account came readily. She had arrived at six fifteen, found Venn on the floor and shouted for help. Someone had called an ambulance while she cut the wire. “Did you touch anything before the police arrived?” Quinn asked. “Only his keys. And him, to feel for a pulse.” “Which pocket were the keys in?” “His coat.” “He isn’t wearing a coat.” “His trousers, then. It was a shock.” “You borrowed the shears yesterday?” “Yes.” “Why?” “To cut a crate open.” Quinn looked at the trays. “Do you make the candles?” “No. I sell them.” “Were you here last night when Miss Kowalski argued with Venn?” “I was packing up.” “What was the argument about?” “A faulty compass, I think.” Eva made a small sound behind Quinn. “A lamp.” Lark’s eyes shifted to her. “Well, you would know.” Quinn looked down at the candles. Several had been packed in paper sleeves. A lump of dark blue wax had hardened on the edge of the nearest tray. She thought of the crescent on Venn’s floor. “Your candles drip much?” “They’re candles.” “May I see one?” Lark selected a blue one and held it out. Quinn examined its base. A thin paper label had been stuck there with brown gum. Part of the label had peeled away, leaving a curved edge. The wax on Venn’s floor had a strip of brown paper embedded in it. “Do you sell to Venn?” “Sometimes.” “Did you sell him one of these?” “I don’t remember.” Quinn handed the candle back. “You cut the wire from outside the stall?” “Yes.” “With Venn’s shears.” “I’ve told you.” “Show me how you held them.” Lark took the shears from the counter when the investigator brought them over. She mimed cutting in front of her, the long blades pointing away from her body. Quinn returned to the cage. The cut ends of the wire curled outward, toward the platform. She took the shears herself, holding them as Lark had. The jaws closed in a way that would push the severed wire inward. Patel watched her repeat the motion. “Could she have turned them?” Quinn turned the shears over and tried again. The wire would still bend away from the blades. To curl outward, it would have to be cut from inside the stall. Lark said, “I don’t see what that proves.” “It means you were inside when you cut the hole.” “I reached through.” “The hole wasn’t there yet.” For the first time, Lark’s expression slipped. “I must have cut it the other way.” “Perhaps.” Quinn handed the shears back to the investigator. “And perhaps Venn bought one of your candles, and perhaps he picked up a compass after he was stabbed without getting blood on it. I’d like to know why all those things happened together.” Lark opened her mouth, then closed it. Patel moved to her side. “Where were you before six fifteen?” “Here.” “You said you arrived at six fifteen.” “I said I found him then.” Quinn returned to the clean rectangle beneath the workbench. “What sat here?” Lark’s gaze went to the gap and stayed there a fraction too long. “A box,” Eva said quietly. “He kept a box there. Oak, with a brass clasp. He showed me a lens from it last night.” “Did he lock it?” “Yes.” Quinn looked at the damaged drawer, then at the brass filings on the floor. “The drawer was forced after the box was moved. The filings fell into the empty space.” Patel came to look. “Someone wanted us to think this was a robbery for cash.” “Someone wanted us to look at the drawer.” Quinn glanced at the compass in the investigator’s hand. “And at the back wall.” Eva frowned. “But if the compass was put there deliberately, it could be pointing to how the killer escaped.” “Could be,” Quinn said. “Unless the killer wanted us searching the wall while she walked out through the door.” Lark took a step back. Patel caught her arm. She jerked against him, hard enough to knock a tray of candles to the floor. They scattered across the tiles. “I found him,” she said. “He was already dead.” “Then tell me about the box,” Quinn said. Lark stared at her. “You took it out before anyone else came down. You put the compass in his hand, shut the stall and locked it. Then you cut the wire from inside your own stall, returned the shears to Venn’s counter and raised the alarm.” “There’s no way from my stall into his.” Quinn looked at the gap between the two enclosures. A canvas sheet hung there, concealing a stack of folded tables. “Move those,” she said. Patel signalled to the constable. Together they pulled the tables aside. Behind them, a section of wire mesh had been fastened with three small hooks. The lowest hook was bent, and fresh scratches marked the iron frame around it. Lark’s face went grey. Patel drew her hands behind her back. “You’re under arrest on suspicion of murder.” “I didn’t stab him,” she said. “I found him and took the box. That’s all.” “Who did stab him?” Quinn asked. Lark’s eyes went toward the platform wall, then away. “You’d better tell me before I find out some other way.” “I didn’t see.” Patel led her toward the stairs. Lark stumbled once on the scattered candles, then found her footing. The elderly woman at the entrance had risen from her table and was watching them approach. Quinn turned back to the stall. “Find the box,” she told the investigator. “Start with Lark’s stock and anything she’s packed for removal. And bag that compass separately.” The investigator looked at its face. “It’s still pointing at the wall.” Quinn went to the back of the stall. The bricks were black with old soot, and a band of yellow paint ran along them at shoulder height. She could see no door, no opening and no obvious place to hide a magnet. Behind her, Eva said, “I didn’t say it showed where the killer went. Only that it points to the nearest rift.” Quinn checked her watch. The worn leather strap had picked up a smear of dust. Above them, Lark’s voice rose sharply, followed by Patel’s, telling her to keep moving. “Can you tell us what’s in Venn’s box?” Quinn asked. “Not everything. He wouldn’t let me look.” “But you wanted to.” Eva hesitated. “Yes.” “Then you can stay while we find it.” Quinn stepped back from the wall and called for another investigator to examine the brickwork. Whatever Lark had taken, Venn had been killed for something, and the woman had just admitted she had reached him before the witnesses did. Quinn wanted the box found before Lark decided exactly how much more she was prepared to admit.
