The dead man lay beneath a sign that said NO EXIT. Someone had polished the sign recently. Everything else in the abandoned station was furred with dust: the tiled walls, the old ticket window, the fluted iron columns disappearing into darkness above the platform. But the red letters shone under Detective Harlow Quinn’s torch. She stopped at the foot of the stairs. “How did you get in?” she asked. DS Bell stood beside a portable scene lamp, rubbing his hands against the cold. “Anonymous caller gave us the address. Uniforms found a service entrance off the canal.” “That isn’t what I asked.” Halfway down the stairs, a steel gate had refused to open. No keyhole, no keypad, no visible bolt. The constable waiting there had passed her a small white disc and told her to push it into a recess in the wall. Bone. She had felt the grain of it beneath her thumb. Then the gate had opened. Bell glanced towards the stairs. “Same way you did.” “And that strikes you as normal?” “Nothing about this place strikes me as normal.” Quinn went down the last three steps. Her left wrist brushed the handrail; she pulled it away, protecting the worn leather strap of her watch from a smear of something sticky and black. The platform had become a street. Stalls crowded both edges, built from doors laid across trestles and cabinets with the backs knocked out. Canvas roofs sagged beneath the weight of the damp. A butcher’s scale hung above jars of pale material suspended in amber liquid. Farther along, glass cabinets held teeth, rings, and small packets marked with names rather than ingredients. Curtains closed most of the stalls. Someone had left a cup of tea on a counter. It still steamed. “Where is everyone?” “Cleared out before the first car arrived. We’ve got one woman.” “Witness?” “Claims so.” “And this is?” “The Veil Market. According to her.” Quinn looked at him. “I know,” Bell said. He handed her overshoes and gloves. The dead man lay on his back inside a stall built into the old ticket office. A partition enclosed it from the platform; a narrow door stood open, its split frame exposing fresh wood. Behind the body, a bank of grimy tiles carried the NO EXIT sign. He was in his late fifties, thick through the chest, wearing a plum-coloured waistcoat over a white shirt. Blood had soaked the shirt beneath his ribs and spread under his right hip. One hand rested palm-up. The other was tucked beneath him. Quinn crouched at the threshold without stepping inside. “Who forced the door?” “First officers. Witness said he was in there and wouldn’t answer.” “Name?” “Witness calls him Vale. Nothing on him except cash and keys.” “Photographs before he was moved?” “He hasn’t been moved.” “Good.” Bell folded his arms. “Door bolted from inside. No windows, no second entrance. Knife beside his hand. Looks fairly straightforward.” “Does it?” “People sell some bad things down here. He’s alone in a locked room with a wound and a weapon. Either suicide or an accident with something he shouldn’t have been handling.” Quinn examined the door. The brass sliding bolt was still extended, torn from its keeper when the constables forced entry. Fresh splinters littered the floor. “Was the witness watching this door?” “Not continuously.” “Then we don’t know he was alone.” “We know no one could leave after they bolted it.” Quinn let that sit. Three years ago, Bell would have expected her to agree. Three years ago, a locked door had still meant a locked door. She moved the torch beam over the body. A narrow-bladed knife lay near the upturned hand. Its handle was ivory-coloured, perhaps bone, carved with shallow grooves. Blood marked the blade but not the handle. “Where’s the witness?” “By the old platform clock.” “Keep her there.” Quinn rose and followed the blood with her light. The principal pool had formed beneath the body. Beyond it, toward the rear wall, three separate drops darkened the grey concrete. Between them lay a faint red smear, thin enough to have been made by a fingertip. Not a clean scene, then. Whatever Bell believed. She stepped carefully around the drops. The rear wall was tiled in cream and green. Old damage showed everywhere: cracked glaze, missing grout, rusty brackets where a noticeboard had once hung. Immediately behind Vale, however, a rectangular section was clean. Not scrubbed clean. No runnels, no cloth marks. Simply free of the grime that covered the rest. Its lower edge stopped six inches above the floor. Quinn leaned closer. Along that edge, drops of blood clung to the tile. They had flattened there in small dark beads. She lowered the torch. A similar row marked the floor beneath. “Bell.” He came to the threshold. “Tell me how that happened.” “Blood spatter.” “Perhaps. From what direction?” He squinted. “I’d want the analyst.” “So would I.” She would also want an analyst willing to come down here and tell her why blood had collected in a perfectly straight line along blank ceramic. On the floor between the wall and the body lay a little brass compass. It was no larger than a pocket watch. Verdigris mottled its casing, and intricate marks surrounded the face where the cardinal points should have been. The glass was intact. “Was that photographed?” “Yes. Don’t touch it yet.” “I wasn’t going to.” The needle pointed toward the wall. Quinn watched it while Bell moved his lamp. As the light shifted, she saw something lodged behind the dead man’s shoulder. A thread. Blue wool caught in a rough patch of grout. Vale’s clothes contained no blue. “Get the photographer back in. Close shots of the wall, the thread, the drops, and that compass. Then I want to speak to her.” The witness sat beneath a clock stopped at twelve seventeen. She was small, with curly red hair and round glasses slipping down a freckled nose. Both hands clasped the strap of a battered leather satchel on her knees. Books pushed its sides out of shape. “Eva Kowalski,” she said before Quinn asked. “I gave the other officer my details.” Quinn introduced herself and remained standing. “Why were you here?” “To buy a reference text.” “What sort?” “A concordance of funerary inscriptions.” “Your occupation?” “Research assistant. British Museum.” “Which department?” “The restricted archives.” Bell made a small sound behind Quinn. She ignored him. “What time did you arrive?” “About nine.” “What time did you find Mr Vale?” Eva tucked a curl behind her left ear. “I didn’t find him. I found the door locked. I came back for my book and he wouldn’t answer.” “What book?” “I’d paid for it. He said he had to retrieve it from storage.” “Behind the ticket office?” “Yes.” “Did you hear anything?” Eva’s grip tightened on the satchel strap. “Miss Kowalski.” “A noise. Earlier. When I was at another stall.” “What kind of noise?” “Like a train braking.” Quinn looked along the black rails. Dust lay undisturbed between the sleepers. “There are no trains running through here.” “I know.” “Did you see anyone leaving his stall?” “No.” “Anyone near it?” “A man in a blue coat.” Bell took out his notebook. “What sort of coat?” Quinn asked. “Long. Wool, I think. I only saw his back.” “Height?” “Tall. Taller than you.” “Age?” “I couldn’t say.” “Did you tell the first officers this?” “No.” “Why not?” Eva looked past her at Bell, then towards the stairs. Quinn shifted half a pace, blocking the woman’s view of him. “Look at me. Why not?” “Because I wasn’t sure he was real.” The station seemed to grow colder around Quinn’s neck. She kept her voice level. “Explain.” “He was standing by Mr Vale’s stall. Then someone crossed in front of me and he wasn’t there anymore.” “People move.” “Yes.” “But?” Eva swallowed. “There wasn’t enough time.” Quinn had heard something like that once before. A warehouse caretaker. A corridor too short to lose a man in. DS Morris entering it ahead of her, calling back that he could see someone. Afterwards, the caretaker had changed his statement. Quinn had not been able to blame him. She glanced at Eva’s satchel. “Put that on the bench.” “Why?” “Please.” Eva hesitated, then obeyed. Quinn asked permission to look inside. There was a long pause before the woman nodded. Books, pencils, a folded museum identification badge, a sandwich wrapped in paper. A blue scarf lay at the bottom. Quinn did not touch it. “Have you worn that tonight?” “Yes.” “Have you been inside Vale’s stall?” Eva’s face emptied. “Miss Kowalski?” “Earlier. When I paid.” “You told me you came back for a book.” “That was later.” “Then you were inside twice?” “No. The second time the door was locked.” Quinn watched the left hand lift towards the red curls and stop halfway. “Do you know anything about the brass compass beside the body?” Eva lowered her hand. “Yes.” “What?” “It’s a Veil Compass.” “What does it do?” “It points to openings.” “Doors?” “Not ordinary doors.” Bell shut his notebook. “Come on.” Eva flinched. Quinn turned her head. Bell’s mouth tightened, but he said nothing else. “Where did Vale get it?” she asked. “A Shade artisan made it. He had it for sale.” “What’s a Shade?” Eva looked down. “I don’t think that’s the question you need to ask.” “Then give me the answer I need.” “The needle points to the nearest rift. Or portal.” Bell exhaled through his nose. Quinn studied the woman’s hands. No visible blood. Nails bitten short. A small red mark across one finger, but old enough to have begun healing. “You expect me to believe that?” “No,” Eva said. “But you asked what it does.” Quinn returned to the ticket office. The photographer had finished and the scene examiner was packing a macro lens into its case. Quinn asked her to stay. Then she stood at the doorway, taking the room in as a whole. Locked door. Dead man. Clean rectangle. She had begun with the door because someone had forced it. Because it was the only way in. That was an assumption, not evidence. “Look at his shoes,” she said. Bell crouched beside her. Vale wore brown leather brogues. The toes were scuffed. Pale grit lodged in the welts and patterned the soles. “This platform’s concrete,” Quinn said. “The stairs are concrete. Where did he pick that up?” “Outside.” “Possibly.” She trained her torch on the blood drops nearest the wall. Each had a narrow extension pointing towards the body. “He was moving away from the wall when those fell.” “Or standing there and coming towards the door.” “Yes. Why?” Bell offered no answer. Quinn pointed at the knife. “No blood on the handle. No obvious transfer on his exposed hand. If he stabbed himself, he let go before he started bleeding onto his fingers. Possible, but it needs explaining.” “So does murder in a bolted room.” “Exactly.” The examiner used a mirror to inspect the hand trapped beneath Vale’s side. Blood streaked the knuckles. The fingers were curled around nothing. Quinn pictured him wounded, backing away, trying to reach behind himself for balance. His hand catching the floor. Falling. Not a man arranging himself beneath a sign. “Can we lift the compass now?” she asked. The examiner checked her photographs, then picked it up with gloved fingers and set it in a shallow evidence tray. The needle swung. Quinn took the tray and moved three steps to her right. The needle turned back towards the clean tiles. She went left. It followed. “Magnet behind the wall,” Bell said. “Could be.” She handed him the tray. “Take it onto the platform.” He looked at her, then carried it out. The needle held its direction. Quinn approached the wall without touching it. At shoulder height, near the trapped wool, two tiles had shifted a fraction out of alignment. Their grout was broken inward. Something had struck them from the room. She pictured Vale bracing a hand there. Or struggling with someone close enough to tear a coat. Along the edge of the clean rectangle, dirt formed a narrow ridge. Not wiped away. Pushed aside. “Get facilities plans,” she told Bell. “Everything they have for this station. Voids, service passages, alterations. No one breaks that wall until it’s been examined properly.” “You think there’s a concealed entrance?” “I think we haven’t found the entrance.” From the platform, Eva said, “Detective.” Quinn turned. The woman stood beside the scene lamp, watched by a constable. Without her satchel she looked younger, almost painfully so. “The Market moves at the full moon,” she said. “Not tonight, it doesn’t.” “You can’t stop it.” Quinn crossed to her. “Was Vale expecting the man in the blue coat?” “I don’t know.” “But you know something you haven’t told me.” Eva pressed her lips together. “The man died in there,” Quinn said. “Whatever you’re afraid of, silence is helping whoever killed him.” Eva looked towards the ticket office. “He wasn’t getting my book from storage,” she said. “He was sending for it.” “From where?” “I don’t know. He wouldn’t tell me.” “How?” Eva glanced at the compass in Bell’s hands. Behind them, something clicked. A small, dry sound. Ceramic against ceramic. Quinn turned at once. The scene lamp shone through the ticket-office doorway. On the rear wall, one cream tile trembled. Dust trickled from its lower edge. Then came a thin metallic shriek. Train brakes, Quinn thought. Bell reached for his radio. The photographer backed towards the door. “Everyone out of the stall,” Quinn said. Her voice carried cleanly across the platform. Training did that much for her. It gave people something to follow while her own mind refused the shape gathering beneath the NO EXIT sign. The clean rectangle had darkened. Not shadow: the lamp still struck it. The tile joints were disappearing one by one. Quinn stepped between Eva and the doorway. For three years she had remembered Morris’s last words as a useless detail. Something said in haste, before the corridor emptied and left her alone. There’s a door here, Harlow. She had searched every inch of that wall. Now the needle in Bell’s tray jerked hard enough to strike its glass, and Quinn finally understood what she had failed to find. “Back to the stairs,” she said. “Nobody goes through that door.”
