The ladder down into the disused station ran forty feet, and every rung whined under Detective Harlow Quinn's weight. She counted them out of habit. Eighteen years in the Met had taught her that numbers kept the mind clean. The platform below stretched into black, its tiled arches sweating with condensation. A generator chugged somewhere in the dark, feeding a string of work lights that turned the scene the colour of weak tea. White-suited scene-of-crime officers knelt in a loose ring around a body near the north end, where the tunnel mouth gaped like a throat. "Down here, guv." DS Callum Pike's voice bounced off the tiles. He stood at the edge of the light, hands jammed in his coat, breath fogging. Thirty-two, ambitious, the kind of detective who treated every case like a box to be ticked and filed. Quinn crossed the platform. Her torch beam swept the ground ahead of her — a habit Morris had drilled into her, back when drilling her had been his job. She pushed the thought down before it could finish forming. The dead man lay face-down beside a folding table, dressed in a moth-eaten overcoat. His throat had been opened from ear to ear. Quinn crouched. She held her torch close to the wound and studied the platform around it. No blood. Not a small amount of blood. Not a smear where rain or water had diluted it. Nothing. The tiles beneath his neck held nothing but dust and a pale ring where the pooling should have been — as if someone had lifted the body, scrubbed the floor, and laid him back down inside the outline of his own crime scene. "Cut himself shaving?" she asked. "Forensics reckon the blood drained out somewhere else and they dumped him here." Pike crouched opposite her, careful not to touch anything. "Squat territory, this. Kids get in through the maintenance shafts. Probably a drug debt. They off him in the tunnels, drag him down here to hide him, and the cold keeps him fresh. It's grim, but it's simple." "His shoes." Pike glanced at them. Brogues, cracked at the heel. "Spotless." Quinn angled her torch along the platform toward the tunnel mouth. Her beam found the flooded maintenance passage beyond the arch — six inches of standing water, black silt curled at its edges, thick handprints of mud on the railing where the SOCOs had come through. "There's one way in. Ankle-deep. You can see every footprint the team's made since they arrived. So how did he walk through that with clean shoes?" "Carried, then. Like I said." "On muddy ground? Where are the carrier's prints? There are two sets of prints on this platform, Pike — ours and the SOCOs'. Nobody dragged a grown man across this platform tonight." She stood and turned in a slow circle, torch low, reading the floor the way other people read a page. Candle stubs ringed the folding table, maybe a dozen of them, burned down to coins of wax. She crouched again and pressed two gloved fingers to the nearest pool of wax. Cold. Rigid. She scraped at the edge and the whole disc lifted away, brittle as toffee. "These candles burned out days ago. Maybe a week. But the body's fresh — rigor's barely started." She held up the disc of wax for Pike to see. "Somebody lit a ceremony down here, waited, and then put a dead man in the middle of it. He didn't die at a ritual. He was arranged for one." Pike's jaw worked. "Or the squatters had their candles, their little goth party, weeks back, and the killers just dumped him wherever the light was decent." "On a platform with no light?" Quinn walked the table's perimeter. Chalk marks dusted the tiles beneath it — arcs and strokes, half of them scrubbed away with something wet. One fragment survived near the table leg: a spiral, cut through with three slashes. The torch trembled in her hand. One degree. She locked her wrist. She had seen that mark before. Scratched into the leather cover of a notebook pulled from the River Thames three years ago, the notebook still in DS Morris's coat pocket, the coat still on DS Morris, the rest of him never recovered. The pathologist had called the spiral "possible gang insignia." She had spent eighteen months trying to prove it was, and failing, and then stopped sleeping properly. "Occult stuff." Pike had followed her gaze. "Kids and their Ouija boards." "Kids don't scrub their Ouija boards with bleach before the police arrive." She circled the body. The dead man's right hand was fisted shut. She nodded to the nearest SOCO, who worked the fingers open with tweezers and lifted out a small brass compass on a tarnished chain. Verdigris greened its casing. Sigils had been etched into the face around the needle. The needle pointed at the bricked-up wall at the end of the platform. Quinn pulled out her phone, opened the compass app, and turned a slow circle. The phone's needle swung to settle on north — behind her, up the platform, toward the river. The brass needle in the evidence bag ignored north. It strained toward the bricks like a dog at a door. "That's broken," Pike offered. "It's broken in one direction." Quinn walked to the wall. The bricks here were old, mortared over, sealed for decades — and yet the air coming off them cut colder than the rest of the station, cold enough that her breath thickened. She pressed her palm flat against the surface. The mortar was warm. "Pike. Come and feel this." He did, and pulled his hand back. "That's not right." "No," she said. "It isn't." Footsteps on the ladder. A young woman came down into the light, small, curly red hair squashed under a wool hat, round glasses fogging the instant she hit the humid air. A leather satchel hung off one shoulder, straining with books. She dug through it as she walked, tucking a loose curl behind her left ear. "You must be the consultant." Quinn had signed off on the request two hours ago — a researcher from the British Museum's restricted archives, attached to the Met's occult liaison file, a file that got opened perhaps once a decade and had gathered dust since the last time Quinn had needed it. "Eva Kowalski. They said you found markings." She stopped at the table, looked at the chalk spiral, and went the colour of the platform tiles. "Oh. Oh, no." "Talk to me." "This is a threshold sigil. Half of one — someone's tried to close it, badly, or open it, worse." Eva set her satchel on the platform and knelt, pulling out a notebook already ribboned with page markers. "Detective, what else was on him?" Quinn tilted the evidence bag holding the compass so Eva could see it. Eva's glasses slid down her nose. She shoved them up and tugged at her ear again. "That's a Veil Compass. They point at rifts. Thin places. Where—" She stopped, glanced at Pike, and lowered her voice as though the bricks might be listening. "Where the Veil Market sets up its door. And those—" She pointed at the SOCO's second bag, where a dozen small tokens of yellowed bone had been photographed and collected from the overcoat's pockets. "Those are entry tokens. Bone tokens. You can't get in without one." "In where?" "The Veil Market. It's a market, underground, it sells things that—" Eva flapped a hand, frustrated with the limits of English. "It moves. Every full moon, it packs itself up and reappears somewhere else. Detective, when was the body found?" "Four hours ago." "What was the date yesterday?" Pike checked his phone. "The ninth." "Full moon." Eva stood and turned a full circle, reading the platform the way Quinn had read it, and Quinn watched the same realisation land on a different face. "The market was here. Last night this platform was full — traders, stalls, dozens of people. And this morning it's gone, and it left him behind. He was found in the middle of a crime scene that has packed itself up and walked away." Quinn looked down the platform. The folding table. The candle ring. The scrubbed chalk. The warm wall with its cold, wrong air. A dead man carried in through mud he never walked through, laid in the centre of a ceremony that had ended a week before his heart did, with a compass in his fist pointing at a brick wall that had no business being warm. "He wasn't killed here," she said. "He wasn't even killed last night. He was killed somewhere else, kept somewhere cold, and delivered. Positioned. Somebody wanted him found exactly like this, in exactly this spot, on the one morning the market had gone and there was nothing left to hide." She turned the compass bag over in her hand and watched the needle hold its line. "Whoever did this knew the market's schedule. Knew when it would empty this place out. Knew we'd find a chalk spiral and a bone trinket and file it under squatters and superstition." She looked at Pike. "Which is almost exactly what you did." Pike's mouth opened, closed. "Detective." Eva had her notebook out, pencil hovering, freckles stark under the work lights. "The sigil on the floor — I've seen that spiral before, with the three cuts through it. In the archives. It isn't a threshold mark at all. Somebody's put it there to look like one." She tucked the curl back behind her ear for the fourth time. "I'd need a day with the restricted stacks to be certain, but if I'm right, the person who staged this wanted the market's people to think a door had been closed here. They wanted the market to run scared." Quinn slipped her watch free of her cuff and checked it, though she'd checked it on the ladder. An old habit, from a case that had never closed. "Get me everything the museum has on that spiral," she said. "And Pike — nobody files this as gang-related. Nobody files it at all until I say. I want that wall photographed, every brick catalogued, and I want to know who else in this city keeps a file on things that move when the moon is full." She looked at the compass needle, steady on the bricks, patient as a held breath. "Because somebody went to a great deal of trouble to leave us a signpost," she said. "And I intend to follow it."
