The bone token had the weight of a coat button and the colour of weak tea. Quinn pressed it to the iron door, which had no keyhole, and felt the lock withdraw behind the metal. A constable had given her the token at street level with the warning that Miss Kowalski wanted it back intact. Quinn turned it between her gloved fingers. Three grooves crossed its surface. A hole had been drilled off-centre, and something dark had collected in the bore. She noted the time on her worn leather watch: 02:43. Camden still murmured above her, buses grinding over wet tarmac, a siren stretching itself thin somewhere towards Mornington Crescent. Below the door, forty-two steps descended into a station that no longer appeared on public maps. Police lamps stood along the platform. Their hard white glare stripped the colour from the tiles and left the track bed in strips of shadow. The rails had been lifted, though the chairs remained in rows, furred with rust. Chalk squares marked the floor between the columns. Hooks hung from wires where no lamps remained. Black wax had pooled around a champagne cork; beside it lay a chicken’s foot and an empty jar labelled in a hand Quinn could not read. The body lay beyond the old ticket barrier. DS Mercer waited beside it with his notebook closed. “Robbery,” he said before she reached him. “Leonard Fitch, fifty-two. Dealer in antiques when the provenance held up, receiver when it didn’t. We’ve had him twice for handling. His wallet’s gone, his pockets are inside out, and whatever he brought to sell isn’t here.” “Apart from the object in his hand.” “A brass compass. Not worth killing anyone over.” Quinn looked along the platform. A woman sat on a bench outside the tape, both arms locked around a worn leather satchel. Books distorted its sides. Curly red hair had escaped around her face, and her round glasses reflected the lamps whenever she turned towards the body. “And Miss Kowalski?” “Says she found him. Says she came to meet him, which makes her either a witness or the other half of the transaction.” Mercer lowered his voice. “She also says this was a market until three nights ago. Then it moved.” “Did she say where?” “She was waiting for someone to ask the moon.” Quinn stepped over the tape and approached the woman. Eva Kowalski’s museum pass hung beneath her coat collar: research assistant, restricted archives. Freckles stood out across her cheeks. She tucked hair behind her left ear, but it sprang back before Quinn reached the bench. “What time did Fitch telephone you?” “Twenty past midnight. He said he had an instrument the museum ought to examine. He wouldn’t discuss it on the phone.” “So you came to an abandoned station alone.” “I came to the Veil Market. There’s a difference when it’s open.” “Your statement says it wasn’t.” Eva’s green eyes flicked towards the chalk squares. “It moved at the full moon. It always does. The stalls, the sellers, the licences, such as they are. What you can see is rubbish and pitch marks.” “You still needed a bone token to enter.” “The door opens for the token. It doesn’t care whether there’s anything left to sell.” Quinn glanced at the satchel. “What did Fitch want you to examine?” “A compass.” “Convenient that he had one ready for you to identify.” Eva’s fingers tightened on the satchel buckle. “He said it had found something he couldn’t identify. That’s why he called me.” Mercer joined them, his notebook still tucked under one arm. “Illegal market, disputed price, knife. Fitch’s associates ran when your witness started down the stairs. We don’t need a moving address or a supernatural instrument.” “No,” Quinn said. “We need the scene to agree with you.” She returned to the body. Fitch had been a broad man, heavy through the chest and shoulders. He lay on his back with his head pointed towards the tunnel and one knee bent. A single dark puncture marked his shirt beneath the left ribs. Blood had soaked a patch no wider than Quinn’s hand. None had pooled beneath him. His right hand rested on his stomach, closed around a small brass compass. The left lay open beside his hip. Green stained the creases of that palm and the pads of the thumb and forefinger. Quinn walked around him without crossing the photographer’s markers. She stopped at his feet, then at his head. Mercer watched her. “Knives don’t oblige us with arterial spray. He could have bled internally.” “He could.” She crouched beside the torso. A dried runnel descended through the shirt fabric towards Fitch’s belt. A second stain crossed his left side, thin and dark where the cloth had folded against him. “He was upright after the knife went in. Long enough for the blood to run down. Then he lay on his left side.” “Before or after someone carried him in?” “That depends on whether your carriers wore hovercraft.” Mercer’s jaw shifted. “Explain.” Quinn pointed her torch at the floor without switching it on. Dust coated the platform in a skin of soot and plaster. Yellow flags marked Eva’s footprints from the stairs to a point two metres from the body, then back again. The first officers had added their own paths. SOCO had laid stepping plates beside them. No other prints disturbed the dust. “Fitch was thirteen stone, perhaps more. Nobody dragged him. There are no heel furrows and no smear beneath his shoulders. Nobody carried him without putting a heel down. If they brushed the floor afterwards, they did it without leaving a brush mark or disturbing the blood on his shirt.” “They could have worn covers.” “Covers hide a tread pattern. They don’t abolish weight.” She moved the torch beam to Fitch’s exposed sole. Yellow clay filled two grooves in the rubber. The rest of the tread was dry. “Every boot that came down those stairs picked up soot. His didn’t. He brought that clay with him, and it isn’t on your platform.” Mercer opened his mouth, then looked at Eva’s footprints again. Quinn rose and studied the hands. Fitch’s watch rode his right wrist. Quinn’s own sat on her left, its strap pale where years of fastening had polished the leather. “Left-handed,” she said. “Or he liked wearing his watch there.” “The compass left verdigris on his left palm. There’s none on his right. His right cuff is also fastened. His left isn’t.” “You think the compass was planted.” “I think the hand around it is part of the arrangement.” The photographer finished his close-ups and stepped back. Quinn took the compass between two fingers. Verdigris mottled its casing. Protective sigils covered the face in lines so fine they vanished unless the glass caught the light. There were no cardinal points. The black needle pointed along the platform. Behind her, Eva’s shoes scraped the floor. “That’s a Veil Compass.” Quinn kept her eyes on the needle. “You recognise the sigils?” “Some of them. The museum has drawings, not an intact example. They were made by Shade artisans and sold through the Market.” “What does it do?” “It finds openings. Rifts, portals, passages between places. It points to the nearest one.” Mercer gave the tiled ceiling a patient look. “Or it finds the nearest magnetic field. We’re in a Tube station.” Quinn rotated the compass until the sigils lay upside down. The needle travelled around the face and settled in the same direction. She walked six paces towards the tunnel. Its bearing changed. When she stopped, it pointed behind her at the same stretch of wall. She held it over the iron chairs in the track bed. The needle twitched, then returned to the wall. She repeated the test beside a steel stanchion and again beneath a police lamp’s battery pack. The compass continued to reject north, iron and Mercer’s explanation. “Which wall?” she asked. Mercer unfolded a station plan from his folder. “Cross-passage behind it. It connected to a service lift. Both were filled when the station closed.” “Show me.” He put the plan on the ticket barrier and traced a pencil line with one finger. “Solid infill. No other access from this level.” Quinn approached the wall with the compass held flat. The needle aimed between two rusted advertisement frames. Condensation silvered the tiles on either side. A door-sized section between them remained dry. She lowered herself to one knee and set her torch on the floor. Light skimmed across the dust. A pinhead of blood appeared near the skirting. A second spot marked the grout at the base of the dry tiles. Between them lay a crescent of yellow clay, no longer than her fingernail. It rested on top of the soot. A cobweb crossed the upper corner of the wall. At waist height, its strands ended along a line finer than a crack. The rest hung from that unseen border, supporting nothing. Quinn did not touch it. She moved the compass an inch to the left. The needle corrected her. Mercer came up behind her. “A hidden door doesn’t make this occult. If there’s a void, someone could have opened it from the other side.” “It makes your staircase irrelevant.” “It could still be robbery.” “It could still be the motive. It isn’t this scene.” She stood and faced him, keeping the compass between them. “Fitch stood after he was stabbed. He then lay somewhere on his left side. Someone fastened his story around him afterwards: compass in the wrong hand, wallet gone, watch left behind because a watch would have complicated the robbery. His body reached this platform without using the stairs, crossing the dust or leaving a carrier’s footprint. That clay is the only soil he brought with him.” Mercer looked at the dry tiles. “And you’ve decided he came through a wall.” “I’ve decided the wall is the only route your evidence hasn’t excluded.” “Because of that compass?” “Because every other route failed before I picked it up.” Quinn returned the compass to the photographer’s open evidence tray and stripped off her gloves. “Get the construction plans, not the public survey. I want the cross-passage, the service lift and any work order that mentions infill. Have the wall photographed with the light at floor level before anyone touches it. Fitch wasn’t killed during a deal here. He was killed elsewhere, arranged elsewhere and delivered to a place where the Market’s leftovers would explain him.” Mercer’s pencil hovered above the station plan. For the first time since Quinn had arrived, he opened his notebook.
