The way down was a maintenance stair behind a steel door in an alley off Camden High Street, the kind of door the city forgot it owned. Quinn descended with her torch held low, one hand skimming the wall, counting steps out of old habit. Forty-one. The air changed at thirty—colder, mineral, wet soot and old grease, the smell of a place that had been holding its breath since before the war. DS Cole waited at the bottom, young and damp and trying not to look pleased about the overtime. "Body's on the platform, guv. Couple of urban explorers found him around two, had a crisis of conscience, called it in from a payphone." He caught her look. "There's one still working on the Holloway Road. They didn't give names." "Course they didn't." The tunnel opened onto a platform tiled in oxblood and cream, half the tiles fallen, the rest filmed black. Old posters clung to the curved wall in flakes—someone's smiling face advertising a film forty years dead. SOCO had rigged lamps, and the light made everything worse, the way a wound looks worse cleaned. The man lay on his back beside the platform edge, arranged almost neatly, hands at his sides. Mid-thirties. Good coat, good boots, no wallet, no phone, no keys. His eyes were open and frost had feathered his lashes, though the tunnel air sat at a mild twelve degrees and Quinn had sweated through her shirt on the stairs. "Rave," Cole said, behind her. "Has to be. They find these old stations, put the word out, couple hundred people down here with speakers. Look—" his torch swept the floor, "scuffing everywhere. Wax stubs on the benches. Chalk marks on the wall, someone smeared them but you can see. He took something bad, his friends panicked, tidied him up, left him." Quinn crouched. Her knees objected. She ignored them. "Whose scuffing?" she said. "Sorry?" "Show me a footprint." Cole's torch moved again, slower this time. The platform floor lay under a skin of dust so even it might have been poured. The explorers' prints ran from the far staircase to the body and back, two sets, one dragging a heel. SOCO's prints clustered near the lamps. Nothing else. The scuff marks Cole was so proud of sat under the dust, dulled by it, days or weeks old. Whatever crowd had made them had made them long before tonight, and nobody—nobody—had crossed this platform since. "He didn't walk here," Quinn said. "Nobody carried him. No drag marks. So either he flew, or—" She stopped. She didn't have an or. "Staged," Cole said, recovering. "Pros. They dusted after themselves, that's why the scene reads wrong." "Dusted." She looked at him until he looked away. "With what, a fog machine full of brick dust? They'd have had to lay it fresh over the whole platform and not leave a single print in it. Use your eyes, Cole." She leaned closer to the body. Rigor had come and nearly gone, which said a day dead, maybe more. But the frost on his lashes hadn't melted under the lamps, and when she lifted his cuff with a gloved finger, the watch on his wrist—an expensive thing, steel, still running on her own wrist in worn leather, still ticking against her pulse—his had stopped at 3:07, and the crystal was crazed from the inside, as if the cold had come out of him rather than into him. She knew the smell a second before she named it. Ozone. Faint, under the soot. The smell of a struck bell, of the air after lightning. She had last smelled it three years ago, in a lock-up garage in Bermondsey, standing over what was left of DS Morris. Her jaw set until the muscle ached. She kept her face the way she kept her bearing—military, borrowed from a father who'd borrowed it from a regiment—and she opened the dead man's fist, which the pathologist's assistant had already loosened, and looked at what he held. A disc of bone, small as a shirt button, carved with a spiral and holed through the center. Quinn did not move for three full seconds. In the left pocket of her coat, wrapped in a handkerchief, where it had ridden every working day for three years against all regulation and all sense, was an identical disc. It had been found under Morris's body. She had never logged it. She had never told anyone. She had taken it home and held it under a lamp and told herself she would understand it eventually, and eventually had never come. "Guv?" Cole said. "Bag it. Photograph it first. Twice." She straightened and walked the platform edge, torch down, and found the second thing under the bench, where it had rolled or been kicked: a small brass compass, cased in verdigris, its face etched with marks that were not cardinal points—sigils, fine as engraving on a wedding ring. She lifted it with a pen through its loop and watched the needle. It did not point north. It pointed down the tunnel, into the dark beyond the lamps, steady as a dog on a scent. She turned in a slow circle, and the needle turned with her, faithful to something she couldn't see. "Broken," Cole offered, at her shoulder. "Broken compasses spin," Quinn said. "This one's made up its mind." She was still holding it when one of the uniforms leaned in from the staircase and said they'd detained a woman at the alley door, said she'd been standing at the tape for ten minutes asking the PC whether anything had been found below, and wouldn't leave, and wouldn't say why. "Bring her down," Quinn said. The woman was small, five-four in boots, with curly red hair escaping a clip and round glasses gone spotty in the damp. Freckles. Green eyes that took in the platform in one fast, practiced sweep—not the way gawkers looked, Quinn noted, but the way searchers looked—and a worn leather satchel clutched crosswise over her body, heavy enough to pull her shoulder down. "Name." "Eva Kowalski." A pause. A hand came up and tucked a curl behind her left ear. "I'm a researcher. British Museum. I study disused stations—I'm writing a paper on—" "At four in the morning. In an alley in Camden. At an active police cordon." "I heard something on a scanner app," Eva said, and tucked the hair again, and Quinn filed the gesture away the way she filed everything. "I only wanted to know if—if anyone was hurt." "Anyone," Quinn said. "Not the man. Not a body. Anyone. You didn't know what was down here, but you knew something was." Eva's mouth closed. Behind the glasses, her eyes flicked—once, involuntary—to the compass hanging from Quinn's pen, and something went through her face that wasn't surprise. It was recognition, and under the recognition, fear, and under the fear, plainly, the decision to lie about both. "Pretty," Eva said. "Is it his?" Quinn had worked this clique's edges for eight months—surveillance logs, half-legible photos, names in a notebook with no charges attached. Kowalski. She had the name in her own handwriting, three pages deep, flagged next to a flat in Islington and a woman called Aurora. And here the woman stood, at four in the morning, at a door beneath Camden, lying badly about a compass she had clearly seen before. The needle moved. Quinn felt it through the pen, a twitch, a swing—and it no longer pointed down the tunnel. It pointed, quivering, at Eva Kowalski's satchel. Quinn looked at the satchel. Eva's hand closed over the flap. "Ms. Kowalski," Quinn said, voice level, pleasant, the voice that preceded very bad news, "we're going to have a proper conversation somewhere with better lighting. Cole—take her details, and I want her satchel inventoried in front of her, item by item, including any books." "You can't—" Eva stopped herself. Swallowed. "I'd like to call someone." "Everyone would." Cole led her up the stairs, gently, talking the whole way, and Quinn stood alone between the lamps with the compass and the bagged bone token and the dead man frosting quietly under the lights. She took the handkerchief from her pocket and unwrapped Morris's disc and held it beside the photograph she'd just taken on her phone. Same spiral. Same hole. Same bone, yellowed the same way, like teeth from the same skull. Three years. She had told herself the Bermondsey scene was staged too, that the smell was a faulty generator, that the cold spot was a draught, that the token was a gang marker she'd decode eventually. She had built a rational room and locked herself inside it, and tonight the walls had dust on the inside, laid fresh, over scuffs she could no longer explain. "Cole," she called up the stairwell. "Add to the canvass. I want every report in the last eighteen months—any body, any location—where the scene reads staged but the forensics read wrong. Cold anomalies. Ozone. Watches stopped." She looked down the tunnel, where the dark went on past the reach of the lamps, the direction the needle had wanted. "And pull everything we have on Eva Kowalski and her friends. All of it. Tonight." The compass hung from her pen, and the needle had swung back to the tunnel dark, patient, certain, pointing at a place that wasn't on any map she'd ever signed her name to. Quinn put Morris's token back in her pocket, next to her heart, and went up the stairs to begin.
