The call came in at 4:47 a.m., which was the sort of hour Quinn had learned to distrust. Nothing good happened at 4:47 a.m. Nothing honest, anyway. She ducked under the police tape strung across the mouth of the disused Tube entrance, the old Camden Town North platform that had been sealed since the eighties, according to the property records nobody had bothered updating since. The stairwell smelled of damp brick and something sweeter underneath, something that made the back of her throat itch. "Detective Quinn." DC Reyes met her halfway down, torch beam bouncing off tiled walls gone black with soot and neglect. "Wasn't sure you'd want to come out for this one personally." "Body in a sealed station tends to get my attention." "Not sealed, exactly. Someone's been down here." Reyes gestured at a chain-link gate, its padlock cut clean through, the metal edges bright and unrusted. "Recent. Within the week, forensics reckon." The platform opened up below, lit now by portable floodlights that threw everything into a flat, clinical white. The victim lay near the platform edge, a man in his fifties, business suit, no visible wounds that Quinn could see from the stairs. "Talk me through it," she said, descending the last few steps. "Male, mid-fifties, no ID on him yet. No blood, no bruising, no obvious cause of death. Pathologist's guessing cardiac arrest, but she won't commit until the post-mortem." Reyes flipped his notebook open, though Quinn suspected he had the details memorised. "My money's on a heart attack brought on by fright. Bloke wanders down here looking for God knows what, disused station, dark, damp — gives himself a scare, keels over." "What was he looking for?" "That's the interesting bit." Reyes crouched by the body, careful not to touch. "Pockets are empty. No wallet, no phone, no keys. Someone's been through him." Quinn knelt on the opposite side, close enough to see the frost. It shouldn't have been there. The station sat below ground in high summer, the air thick and stagnant, and yet a thin rime of white crusted the dead man's collar, his cuffs, the exposed skin of his throat. She touched it with one gloved finger. Cold, but not melting, not even under the floodlight's heat. "Reyes. Has anyone bagged this?" "Frost? No, why would—" "Get someone to bag it before it's gone." She straightened, scanning the platform. Brick dust had been disturbed in a wide arc around the body, sixty degrees or so, like something had swept through and pushed the grime aside without touching the ground itself. No drag marks. No footprints inside the arc, though the platform outside it showed at least three distinct shoe patterns, badly smudged. "Could be from the draught," Reyes said. "These old tunnels get wind through them, ventilation shafts, that sort of thing." "Wind that selectively avoids leaving footprints but disturbs forty years of dust in a perfect curve." Quinn moved along the arc's edge, crouching again near the tiled wall. Scratched into the surface, hidden under a film of soot she brushed away with her thumb, was a symbol — three interlocking circles, each stamped through with a single line, like a compass needle frozen mid-spin. The edges of the scratch marks gleamed faintly green, a patina she recognised but couldn't place, not immediately. Verdigris. Fresh verdigris, on a mark that looked freshly made. "Someone's done that for a laugh," Reyes said, following her gaze. "Kids, probably. Urban explorers get down here more than the transport authority likes to admit." "Kids carrying enough brass to leave a copper residue an inch deep into stone." She held up her hand, fingertips faintly green now themselves. "That's not paint, Reyes. That's corrosion. It takes years to do that to brass. Not minutes." "So it's old. Predates the lock being cut." "Then how is it not covered in the same soot as everything else down here?" Reyes didn't answer that one. Quinn watched him not answer it, watched the little crease appear between his eyebrows, the one that meant he was recalculating, and for a moment she almost enjoyed it. Almost. She turned back toward the body and noticed, for the first time, the man's shoes. Good leather, expensive, barely worn — except at the heels, which were scored with fine parallel scratches, as though he'd been dragged, feet-first, across rough ground. But there were no drag marks on the platform. None at all. "He wasn't killed here," she said. "Body's here." "Body's here. Death happened somewhere else. Somewhere with a floor that could leave those scratches, then he was moved, without dragging him across this platform, without leaving so much as a smear in forty years of dust." She looked up at the curved ceiling, at the ventilation grate rusted shut above the far end of the platform, at the absolute, total absence of any logical way a corpse could arrive at this exact spot without disturbing anything around it. "Tell me how that's possible." "I can't," Reyes admitted. "Maybe he was carried. Sheet under him, someone lifts him, sets him down careful." "Through a padlocked gate that was cut open from the platform side, not the stairwell." She'd already checked; the cut edges of the chain faced outward, toward the tunnel beyond the platform, not toward the stairs where any sane person would enter. "Whoever did this didn't come down those stairs at all." Reyes stood very still for a moment, the torch beam trembling slightly in his hand, the first honest thing he'd done since she arrived. "Then how'd they get in?" Quinn didn't answer. She was looking past him, into the black mouth of the tunnel beyond the platform's edge, where the floodlights didn't reach and the frost on the dead man's collar seemed, if she watched closely enough, to still be spreading.
