The escalator ended in a wall of bricked-up advertisements. Someone had painted a door on the mortar in black, down to the brass handle and a keyhole shaped like a tooth. A constable stood beside it, holding a sliver of bone between finger and thumb. “It opened for Sergeant Malik,” he told Detective Harlow Quinn. “I’ve knocked three times. Nothing.” Quinn touched the painted handle. Cold brick met her palm. “Where did you get that?” “On the floor. There were six of them.” “Where are the others?” “Malik took one. The paramedics took two. I bagged the last two.” Quinn held out her hand. The constable dropped the sliver into it. One end had a hole drilled through it; grease darkened the edges. “Any signs of a mechanism?” “We looked for a catch. There isn’t one.” Quinn pressed the bone against the painted keyhole. The handle turned under her other hand. The door opened onto a Tube platform. Stalls crowded the length of it beneath dead fluorescent tubes. Their owners had strung lamps from the ceiling and covered the old advertisements with canvas. One stall displayed glass eyes in trays of salt. Another held jars of yellow powder, each sealed with a strip of red paper. No traders remained, but their goods still lay out, and a kettle whistled somewhere beyond the far end of the platform. Quinn put the bone in an evidence bag. Sergeant Malik waited beneath a station clock with no hands. He had rolled his sleeves to his elbows, exposing blue nitrile gloves. “Paramedics confirmed death at twenty past ten,” he told her. “No identification on the body. One witness, one knife, no sign of a struggle.” “Who called it in?” “The witness. She found a phone signal at the top of the stairs.” “And the rest of the market?” “Gone before we arrived. She says they scattered when she found him.” Quinn glanced along the platform. A string of meat hooks swung above a bare counter, though the air felt still. “You let them leave?” “They left before I got here. The witness stayed.” Malik led her past a stall stacked with books bound in cracked leather. A young woman sat on an upturned crate beside it, her satchel clamped between her feet. Round glasses enlarged her green eyes. She tucked a red curl behind her left ear as Quinn approached. “This is Eva Kowalski,” Malik said. “She works at the British Museum. She knew the victim.” “His name was Daniel Voss,” Eva said. “He dealt in manuscripts. I came to collect a catalogue he’d borrowed.” “From the museum?” “From me. It was my copy.” “Did you find it?” Eva shook her head. The body lay behind the bookstall, on a strip of red carpet between two trestle tables. Voss wore a charcoal coat over a pale shirt. A knife protruded from his chest, its bone handle level with the third button. His hands rested at his sides, palms up. Blood had soaked through his shirt and spread beneath him in a dark pool. Quinn crouched without touching the carpet. Her worn watch strap creaked against her left wrist. “Who moved him?” “No one,” Malik said. “The paramedics checked for a pulse and stepped back.” Eva rose from the crate. “He wasn’t like that when I found him.” Malik turned to her. “You told me he was on his back.” “He was. His coat was open.” “The paramedics might have closed it.” “They didn’t. I watched them.” Quinn studied the coat. Its right side lay beneath Voss’s shoulder, creased and dark with blood. The left covered his chest, except where the knife had punched through wool and shirt. “Did you touch him?” Quinn asked. “I checked his neck. Then I pulled my hand away.” “Which side?” “His left.” Eva showed her right hand. A brown smear marked the base of her thumb. Quinn looked at Voss’s neck. Blood streaked the skin below his right ear, on the side away from Eva. Malik took out his notebook. “You said you checked for a pulse.” “I did.” “Then how did blood get on your hand?” Eva’s fingers tightened around her satchel strap. “His collar had blood on it. I moved it.” Quinn leaned closer. The collar on Voss’s left side was clean. The right collar had a wet, black edge. “Show me,” she said. Eva knelt opposite her. She reached towards Voss’s neck, stopped short of his skin and hooked her fingers under the left collar. “Like that.” Her thumb faced the cloth. “Was the blood wet?” “Yes.” “Was there a knife in him?” “No. I would have seen it.” Malik looked from Eva to the body. “You left him here and went up for a signal. Anyone could have come back.” “I didn’t leave at once. I shouted. People ran. Then I went to the stairs.” “How long?” “I don’t know. A minute.” Quinn pointed at the knife. “The blade went through the coat. If his coat was open when she found him, somebody put it there afterwards.” “Or she missed it.” “Look at her hand.” Malik bent over Voss. The knife handle rose above the collar, close enough that Eva’s wrist would have struck it. “All right,” he said. “Somebody came back. Why put a knife in a dead man?” Quinn examined the blood on the shirt. The cloth around the blade had split, but the torn edges remained pale. A thin dark line followed the blade into the wound; the larger stain spread from higher up, beneath the collar. “Where did he bleed from?” she asked. Malik pulled a penlight from his pocket. He angled it beneath the open edge of the coat, then stopped. “There’s a cut under the collarbone.” The gash ran nearly three inches across Voss’s shirt, above and to the left of the knife. Its edges had dried against his skin. “The paramedic saw the knife and left it in place,” Malik said. “She didn’t open the coat.” “Neither will we. Get photographs of the collar and both wounds before the pathologist moves anything.” Malik spoke into his radio. Quinn stood and surveyed the carpet. The blood pool ended at a straight edge beside Voss’s right shoulder. Beyond it, the red fibres showed no stain. “The carpet’s been moved,” she said. Eva looked down. “I don’t think so. It was between the tables when I arrived.” Quinn followed the straight edge with her eyes. It did not match the carpet’s border. It matched the long side of a shallow wooden tray on the nearer table. The tray stood empty except for a scatter of grey dust. Its underside carried a dark smear. “Was that there?” Quinn asked. Eva came around the table. “There were papers on it.” “What papers?” “Loose leaves. Daniel kept them under glass.” “Where’s the glass?” Eva pointed to the floor beneath the table. A rectangular pane leaned against one leg. Quinn crouched beside it. One corner had chipped, and a small crescent of glass lay in the dust. Malik joined her. “Somebody knocked it off during the attack?” “The chip’s underneath the pane,” Quinn said. “It was set down on top of the piece.” She looked at the tray again. A narrow clean strip ran across its dusty surface, interrupted by four small circles. “What held the papers down?” “Brass clips,” Eva said. “Four of them.” “They’re gone too?” Eva nodded. Malik drew a breath through his nose. “Somebody killed him for the pages, shifted the tray over the body and put a knife in him.” “Why shift the tray?” Quinn asked. “To hide where the pages had been.” “The dust already showed that. And the tray has blood on its underside.” She moved to Voss’s feet. The soles of his shoes faced away from the tables. A small brass compass lay beside his left heel, its casing green with verdigris. Someone had opened it. Fine marks circled the face, and its needle pointed towards the brick wall behind the bookstall. Quinn took a compass from her coat pocket and checked it against the one on the floor. North lay in the opposite direction. “Is that his?” she asked Eva. “I’ve seen him carry it.” “What did he use it for?” Eva tucked the curl behind her ear again. “He called it a Veil Compass. He bought it here.” “That tells me where he bought it.” “He said it found openings.” “Openings in what?” Eva looked at the wall. “He didn’t give me a useful answer.” Malik shone his penlight across the bricks. Old soot filled the mortar joints. A strip of clean brick showed beneath the table, level with the height of the tray. Quinn went down on one knee. A second clean strip ran beside the first, and a third beside that. The gaps between them measured roughly the width of a brass clip. “Eva, how wide was the tray?” She held her hands apart. “About that.” “And the glass fitted inside it?” “Yes.” Quinn measured the clean strips against the tray without lifting it. The lengths matched. “The tray stood against the wall,” she said. “Its long side rested on the floor.” Malik looked at the empty table. “Voss put it there?” “Someone did. The wall kept the papers upright. The clips held them to the tray.” “That doesn’t explain the blood underneath.” Quinn looked at the straight edge of the pool, then at Voss’s open hands. “His head was against the tray when he bled. It shielded the carpet. Someone pulled it away and laid him flat.” Malik crouched beside her. “The knife came later. So whoever moved the tray took the papers and staged the stabbing.” “They might have. We know the tray moved. We know the knife went in through a closed coat.” Eva stared at Voss. “I saw the tray on the table when I found him.” Malik straightened. “You’re sure?” “The glass was leaning underneath. I remember because Daniel never left it on the floor.” Quinn walked back to the body. The blood beneath his right collar had soaked into the coat lining, but the outer wool carried only a few drops. She touched neither, tracing the line in the air. “He was wearing the coat when he bled. Someone opened it afterwards.” Eva’s hand rose to her hair. She caught herself and lowered it. “I opened it. I thought he might still be breathing.” “Did you move the tray?” “No.” “Did anyone stand here with you?” “There was a woman at the next stall. She came over when I called out.” “What did she do?” “She knelt on his other side. She told me to check his neck.” “Which side did she take?” “His right.” Quinn pointed to the blood below Voss’s ear. “Did she touch his collar?” Eva looked at the smear. “She put her hand behind his head.” “Did you know her?” “No. She wore a grey coat. Her hair was covered.” Malik wrote it down. “You didn’t mention her before.” “You asked who stayed. She ran with the others.” The kettle beyond the stalls had stopped whistling. Quinn heard water drip onto the track below the platform. “Was the woman wearing gloves?” she asked. Eva closed her eyes for a moment. “One glove. On her right hand.” “What was in her left?” Eva opened her eyes and looked at the empty tray. “A sheet of glass. I thought she’d picked it up to get it out of the way.” “Where did she put it?” “Under the table.” Quinn glanced at Malik. “Get the pane bagged with the chip beneath it. And ask the constable upstairs whether he saw a woman in a grey coat leave.” Malik raised his radio. Quinn turned back to Eva. “When you first saw her holding the glass, where was the compass?”
