The hoarding around Brackley Street station had been welded shut since 1992, and someone had cut a door in it overnight. Quinn ducked through, torch in hand, and took a maintenance stair that smelled of rust and wet chalk. A constable at the bottom lifted the tape for her. "Old south platform, ma'am. DS Ferro's got the lights rigged." "How far down are we?" "Sixty feet, give or take. No signal down here, so shout if you need anything." Her torch swept the platform edge, the dead escalators, adverts for cigarettes that had been illegal to advertise for two decades. Arc lamps hummed at the far end, and beneath them DS Ferro stood over a shape on the floor, chewing gum like it owed him money. "You're going to love this one," he called. "Or hate it. Fifty-fifty." She crossed the silted concrete. The man on his back had been fifty once. Now his skin clung to the architecture of his skull, and his hands lay curled around the air like he'd died reaching for something. "Fence, by the look of the coat. Camden junkies use the dead platforms for deals — it's practically a branch of Tesco down here." Ferro nudged the air two inches from the man's chest. "Single puncture, over the heart. Rigor's broken, lividity's fixed. He's been dead since around midnight." "Where's his blood?" "That's the kicker. There isn't any. Wound's seared shut, like someone went at him with a soldering iron. Hot spike, drano, whatever they're cooking with this month." Quinn crouched. The puncture was the width of a pencil and closed to a ridge of shiny scar-tissue that had no business on a man eight hours dead. She lifted the man's right hand. His fingers came with it, locked around a small brass compass, its casing green with verdigris, its face etched with fine sigils. The needle sat dead steady, pointing at the bricked-up arch at the end of the platform. "Camden Lock tat," Ferro offered. "Ten quid, comes with a free pouch." She set the compass on the man's chest and walked five paces back the way she'd come. The needle spun in lazy circles. She walked forward again, and it swung and settled, pointing at the arch. "His pockets?" "Token thing. Bone, drilled through. And a notebook." Ferro handed over an evidence bag. The last entry was two nights old, dated the full moon: Settle up. — B. "Dead since midnight." She turned the bag in the light. "Ledger last signed two nights back. And your pathologist will confirm the body weighs nothing, because the boys who carried the stretcher were walking like it was empty." "Fits. Junkies strip a body before we get to it." "Junkies don't take bone marrow through a pencil hole." Ferro stopped chewing. "It's a weird one. I'll give you that." She circled the body. Grey silt lay over everything down here, thick as flour, except for a clean swathe around the corpse, as though the man had been lowered from the ceiling and set down without a foot touching the floor. Two paces off, a ring of frost sat on the concrete. At its centre, one floor tile had fused to a black glass glaze. "That's condensation." "It's frost. It's the eighteenth of July." She held her palm over the ring. Cold climbed off it like water running backwards. "And it's two paces from your dead man. The only mark on this platform, and he isn't standing on it." Boots on the stair. Eva Kowalski came down sideways, satchel banging against the rail, hard hat two sizes too big over her red curls. Her round glasses fogged the moment she hit the tunnel air. Quinn had texted her photos of the tile an hour ago and said one word: come. Eva knelt at the glazed tile and went pale around the freckles. "This isn't chalk. The surface flowed and set. You'd need a kiln." "Acid does that," Ferro put in. "Acid etches. This melted." She pulled a loupe from her satchel and bent closer. "It's a toll-mark. I've seen the pattern in the restricted stacks — merchants stamp their scales with it." "The museum lot," Ferro muttered. "Right." "She consults." Quinn let that sit. "The compass. Look at the face." Eva took it without touching the needle. "Shade work. Those sigils aren't decoration, they're containment. The needle doesn't find north. It finds thin places. Doors." "It's pointing at a wall." "I know." Eva's hand went to her hair and she tucked it behind her left ear, twice. "The market moved two nights ago, on the full moon. It doesn't leave doors behind. It leaves debts." She turned the bone token over in her palm and frowned. "This is a real token. Issued, not bought. Spent tokens go cold and grey." "This one's warm as tea." "Then it was refused." Eva set it down fast, like it had bitten her. "Or it was never his." Ferro rubbed his jaw. "So we're doing this. A market. Under Camden. That moved. Two nights ago." "You've got a man with a sealed heart and no blood in him," Quinn said. "You were doing this the moment you called me down." She laid it out along the floor with her finger, pacing the distances. "He didn't die here. He died on the frost, over there, on the toll-mark. Then something picked him up — something that doesn't press its heels into the dust — carried him two paces and stood him against the arch, facing the wall, like luggage set down at the wrong platform." She crouched at the single trail of footprints that came out of the stairwell and crossed the silt. Bare feet. The toes ran long, the stride ran smooth, and the prints stopped at the brickwork as if the wall had accepted them. "One trail in. None out. And check his shoes — soles are clean. He never walked a step down here. The scene is dressed, Ferro. Someone wanted us to find a tidy body on a spooky mark. What they didn't count on was the frost sitting in the wrong place." "Or he crawled." "Crawlers disturb silt. And crawlers leave their shoes on." She stood. Her thumb found the worn leather strap of her watch and pressed. She'd photographed a glaze like that tile once before, three years back. That file lived in a shoebox at home, not the archive. Eva had gone quiet by the arch, loupe raised to the mortar. "Harlow. This pointing is fresh. Days old, at most. And it's warm." She flattened her hand against the brick, then pulled it away and tucked her hair behind her ear again. "Nothing under Camden should be warm. The ground's been cold since the ice." Quinn drew her penknife along the seam. The mortar curled away soft as candle wax, and inside the compass case the needle pressed so hard against the brass that it trembled. She tore a strip of evidence tape and sealed it across the brickwork where the bare footprints ended. "Scene's bigger than the body, Ferro. Get the drill team down here, and log that needle every time the case opens. I want to know if it moves between now and the next full moon."
