The constable at the foot of the stairs held out a small disc of bone. “Keep it on you, ma’am. Don’t ask me why.” Quinn took it between finger and thumb. It was warm, though the stairwell smelled of wet concrete and old iron. Behind her, Camden traffic hissed through rain. Ahead, a tiled passage descended into a station that did not appear on any current Underground map. “Who gave you this?” “Sergeant Bell. There’s a man at the barrier who won’t let anyone through without one.” “And you let him decide that?” The constable’s face tightened. “We tried going past him. I ended up back at the stairs.” Quinn looked at him. He was young enough to have spots beneath his collar, but his hands were steady. “Twice,” he added. She put the token in her coat pocket and went down. The station had once been called Calder Street. The name remained in flaking blue tiles above the platform, interrupted by a blackened patch where something had burned. There were no trains, no rails, only a deep concrete trench crowded with stalls. Lamps hung from the old signal cables. Their light fell over bottles, bundles of dried leaves, lengths of chain and objects Quinn could not immediately identify. The market had stopped trading, but it had not dispersed. People watched from behind shuttered counters and beneath tarpaulins. A woman with silver coins sewn into her eyelids turned her face away when Quinn met her gaze. Somewhere farther along the platform, something knocked three times from inside a wooden crate. The man at the barrier examined the bone token without touching it. His gloves were white, his suit immaculate. He stepped aside. Sergeant Bell stood beyond him in shirtsleeves, guarding a gap in the police tape. He was broad, balding and sweating despite the cold. “Thank God,” he said. “I’ve got six uniforms down here and every witness has a different name for the place.” Quinn glanced along the trench. “What do you call it?” “The Veil Market, if you ask the people who admit it exists. The rest tell you it’s a private antiques fair.” “Who found the body?” “Trader from the next stall. Name of Lyle. Says he heard a bell, went to complain and found the door locked. Looked through the glass and saw the victim.” “Time?” “Eleven forty-two. He checked his phone before he called us.” Quinn looked at her watch. Twelve eighteen. “Victim?” “Daniel Rook. Forty-eight. Sold old maps, mostly. One knife wound. We’ve got a likely suspect in custody.” “So quickly?” Bell lifted the tape for her. “She was standing over him with the knife.” The stall sat at the end of a row, built into what had once been a staff room. Its door was painted green, the upper half fitted with a pane of wired glass. A handwritten notice behind the glass read PRIVATE. The bolt on the inside of the door had been torn loose, leaving pale splinters around the screws. “How did she get in?” Quinn asked. “Rook let her in, I’d say.” “Lyle saw her through the glass?” “No. He saw Rook on the floor. We broke the door open and found her behind the counter.” Bell led her inside. A forensic photographer was crouched beside the body. She shifted aside while Quinn took in the room. Rook lay on his back between a counter and a wall lined with shallow drawers. He wore a brown waistcoat and a white shirt, the front soaked dark beneath his breastbone. His eyes were open. Someone had put a paper bag over each hand. The stall smelled of dust, metal and a sharp medicinal scent. Maps lay rolled in pigeonholes; others hung from clips on the walls. There was a brass desk lamp on the counter, a ledger, an open tin of peppermints and a small compass with a greenish crust along its rim. Quinn kept her hands in her coat pockets. “Who found the suspect?” “Me. She came up from behind the counter when we broke in.” “Knife in her hand?” “On the floor beside her. Blood on the blade and on her sleeve.” Bell nodded toward a clear evidence bag on the photographer’s case. “Her name’s Eva Kowalski.” Quinn knew the name. Kowalski worked in the British Museum’s restricted archives and appeared in several reports connected to a group Quinn had been trying to investigate. Most of those reports were frustratingly thin. An address visited, an argument overheard, a person who withdrew a statement the next morning. “She say why she was here?” “Research. Says Rook had something she wanted to buy.” “And the knife?” “Says she pulled it out of him.” “Did she?” “The wound’s consistent with the blade. Doctor can tell us more.” Quinn moved around the counter. The floorboards were scratched and stained, but the dust beneath the drawers had been disturbed in a broad smear. A woman’s leather satchel sat open against the wall, its contents spilling out: two books, a notebook, a pencil case. One book had landed face down, its pages fanned across the boards. “Where’s Kowalski now?” “Interview room upstairs. We found an old office with a working door.” “Who’s with her?” “Pritchard.” “Good.” Quinn crouched by the satchel. “She come willingly?” “She asked for a solicitor. Apart from that, yes.” A fresh crescent of blood marked the satchel’s flap. Quinn leaned closer. The leather around it was scuffed, and one of the buckles had broken. “Did she say what happened?” “She says she came in, found Rook on the floor and tried to help. Heard us at the door, but it was locked.” “Why didn’t she call out?” “Claims she did. Neither Lyle nor I heard her.” Quinn glanced at the photographer. “Have you finished this side?” “Nearly.” “I want the satchel photographed where it is, including the buckle.” The photographer nodded. Bell folded his arms. “She had his blood on her, Harlow. The door was bolted from inside.” “Someone bolted it,” Quinn said. “That’s not quite the same thing.” She stepped back to the door. The bolt was a simple brass fitting, the sort sold in any hardware shop. It had been mounted at shoulder height, close to the wired pane. Quinn studied the torn screw holes, then the narrow strip of wood between the glass and the doorframe. There was a dark groove across the paint, almost level with the bolt. A second mark ran over the edge of the frame. Quinn bent to inspect the floor. A short strand of black thread lay against the skirting board. “Bag that,” she said. Bell looked where she pointed. “You think someone pulled the bolt shut from outside?” “Perhaps.” “Then why leave the thread?” “Perhaps it broke.” She took a pen from her pocket and held it across the gap between door and frame. Even with the door closed, there would have been room for a fine line. A loop around the bolt’s knob, a pull through the gap, and the bolt would slide home. The line would have to be drawn out afterward, unless it snagged. Bell watched her. “Kowalski could have done it before we arrived. Make us think someone had locked her in.” “She could. We’ll test it.” Quinn turned back toward the body. The medical examiner had not yet arrived; she would not touch him. From where she stood, she could see a pale fold of paper caught beneath his left hip. “Did anyone move him?” Bell asked the photographer, who shook her head. “His hand was on his chest when we came in,” Bell said. “The paramedic checked for a pulse, then we cleared out.” Quinn studied the floor around Rook. Blood had spread beneath his back, but there was a thinner streak running from the far side of the counter to his shoulder. It had passed through a patch of dust, leaving a clean edge. “He was moved,” she said. Bell followed her gaze. “He could have crawled.” “On his back?” “He could have rolled.” “Then why is the blood underneath him and not across his clothes?” Bell crouched. “Paramedics?” “You said they only checked his pulse.” “Could have been Kowalski. She says she tried to help.” “Ask her if she moved him. Ask the paramedics too.” Quinn went around the counter again. The medicinal smell was stronger there. A brown bottle stood in a wire rack beneath the work surface, its cork lying beside it. A little liquid had dried on the wood. The compass sat directly above the bottle. Its lid was open, exposing a face etched with tiny marks. The needle pointed toward the drawer wall and trembled so slightly that Quinn first thought it was the movement of the lamp. “Who’s touched that?” she asked. Bell glanced over. “Lyle said it belonged to Rook. I don’t think anyone’s moved it.” The needle swung a fraction to the left, then returned. The room had no obvious draught. Quinn watched it settle. At the bottom of the drawer wall was a strip of darker wood, six inches high. It might once have been a skirting board. Its right end stood a few millimetres proud of the wall. Quinn crouched again. On the floor in front of it lay three peppermints, one of them crushed. The tin on the counter was less than half full. “Lyle said Rook rang a bell?” she asked. “That’s what brought him over.” “Where is it?” Bell looked around. There was no bell on the counter. He checked behind it and found a small brass handbell on the floor near the brown bottle. Its handle was smeared red. Bell stared at it. “Kowalski could have rung it.” “Lyle said he went to complain. Ask him why a bell would make him complain.” Bell went to the doorway and called to a uniform. Quinn stayed where she was. A thin scratch ran vertically through the dark wood beside the proud end of the panel. She could see bare timber at its edge. The constable returned with Lyle, a narrow man in a grey cardigan. His eyes flicked to Rook’s body and away. “Your statement says you heard a bell,” Quinn said. “Yes.” “Why did that bother you?” “Daniel rang it for service. Thought it was funny. I’d told him not to.” “Service from whom?” “Anyone he wanted to annoy.” “What time did you last see him alive?” “About half eleven. He borrowed a match.” “And Miss Kowalski?” “She came along after that. Asked if he had a particular map.” Lyle rubbed his thumb against the seam of his cardigan. “I pointed her this way.” “Did you see her go in?” “No. I had a customer.” “Did you see anyone else go in or out?” “No.” “Did Rook have another way out?” Lyle’s eyes went to the drawer wall. It was quick. Quinn might have missed it if she had not been watching him. “No,” he said. “Thank you. Wait outside, please.” When he had gone, Bell said, “You think he did it?” “I think he knows about the panel.” The medical examiner arrived with an assistant before Quinn could pursue it. She stood aside while they began their work, then asked Bell to find out whether anyone had seen Lyle’s customer. She also wanted Kowalski’s account of moving the body, and a photograph of the marks on the door before anyone tried the thread. Quinn remained by the counter. The compass needle had shifted again. It now pointed at the same dark strip but farther to the right. The examiner glanced up. “You’re staring at that thing as if it owes you money.” “Has the body been moved?” “Almost certainly. See the drag through the blood? I’ll want photographs before we lift him. There’s also blood on the back of his waistcoat that doesn’t match the position he’s in.” “Could Kowalski have done it while trying to help?” “She might have. But she’d have dragged him from behind the counter into the middle of the room. I’d like to hear why.” Bell returned with Kowalski’s answer. “She says she didn’t move him. She says he was where he is now when she came in.” “And Lyle’s customer?” “He can’t describe her. Said he was too busy weighing stock.” Quinn looked at the open peppermint tin. “Have we got gloves and a clean tool?” A crime-scene officer brought both. Quinn had him examine the strip of wood. When he slipped a plastic probe into the scratch and eased it forward, a narrow panel opened on hinges at its lower edge. Behind it was a cavity no deeper than Quinn’s hand. It contained a coil of black thread, a folded cloth and a small wooden box. The box was empty. Dust outlined the shape of something rectangular on its bottom. Bell leaned in. “Couldn’t get a person through there.” “No.” The crime-scene officer photographed the contents, then lifted out the cloth with forceps. A peppermint fell from its folds and rolled across the floor. Quinn looked from it to the counter. “Someone opened the tin, put sweets in the cloth and hid the box. Why?” “Could be Kowalski took whatever was in it,” Bell said. “Then hid the box.” “She had an empty satchel big enough to carry the box itself.” “Maybe she was interrupted.” “Maybe.” Quinn looked at the coil of thread. “Get that compared with the strand by the door. And find out if there’s blood on the cloth.” The officer carried the cloth to the light. There was a rusty smear on one corner. Bell drew a slow breath. “Rook hides the box after he’s stabbed?” “Or someone with blood on their hands does.” The examiner called from beside the body. “Detective. There’s paper under him.” She eased the folded sheet free with forceps and laid it on a clean tray. A map, hand-drawn in brown ink. Most of it was blank, but one corner bore the outline of a street Quinn recognised near King’s Cross. Across it ran a heavy black line ending at a small circle. Inside the circle someone had written MORRIS. The letters were cramped and uneven. The final S had been pressed so hard it cut the paper. Quinn felt Bell look at her. She kept her attention on the map. “Could be another Morris,” he said. “Yes.” She had spent three years learning how many Morrises there were in London. She had interviewed two who had received her partner’s post by mistake and a third whose name had appeared on an unrelated invoice. None had made the name easier to see. “Bag it,” she said. Bell waited until the examiner had sealed the map. “You think Rook was trying to send a message?” “I don’t know.” “He could have had that on him when he fell.” “He could.” But if someone had dragged Rook into the room, they might have dragged him over the map without noticing it. Quinn wanted the floor beneath the counter searched for matching ink, paper fibres, anything that might show where it had come from. She gave the instructions, then went upstairs to speak to Kowalski. The interview room had once been an office. A desk stood against one wall, its surface furred with dust except where someone had cleared a space for a plastic cup. Eva Kowalski sat opposite Pritchard, her red curls untidy, round glasses low on her nose. Her left sleeve had been sealed inside a paper evidence bag. She had tucked her other hand beneath her thigh. Pritchard rose when Quinn entered. “Her solicitor’s on the way.” Kowalski looked at Quinn, then at the door behind her. Her face was freckled and very pale. “I’m Detective Quinn,” Quinn said. “I won’t question you until your solicitor gets here. I need to ask one thing for safety. Did you take anything from Rook’s stall?” “No.” “Did he give you anything?” Kowalski hesitated. “He was dead when I found him.” “That isn’t what I asked.” “No. He didn’t give me anything.” Quinn nodded and left her with Pritchard. Outside, Bell was waiting by the stairs. “The line works,” he said. “We looped it around the bolt, shut the door and pulled. Took three tries, but it went across.” “Could the line be removed?” “Twice. Third time it caught on the frame and snapped.” “And Lyle?” “Still downstairs.” “Keep him there. Check his hands and clothes for blood, and see whether he has any of that thread at his stall. Don’t tell him about the box.” Bell started down the stairs, then stopped. “You’re letting Kowalski sit there?” “She’s asked for a solicitor. She’ll sit there until she has one.” Quinn went back to the stall. The compass was still on the counter, its needle now pointing toward the green door. She stood beside it long enough to watch the needle drift toward the wall again. Whatever moved it was not the bolt or the hidden box. The medical examiner’s assistant was preparing to lift Rook. Quinn asked for another photograph of the floor first. From the doorway she could see the route of the drag: out from behind the counter, across the dust, ending where the body lay. It passed within inches of the hidden panel. Someone had killed Rook, disturbed the panel and pulled him into the open. Then Kowalski had arrived, or been brought there, and the door had been bolted. The line made that possible; it did not yet tell Quinn who had pulled it, or why Lyle had waited until eleven forty-two to call. Her watch showed twelve fifty-six. She looked at the gap in the broken doorframe, imagining the black thread stretched through it, and called for the crime-scene officer. “Before anyone cleans this room,” she said, “I want the outside of the frame checked as well. Especially at the bottom. If the line snapped, the other end had to go somewhere.”
