The abandoned Camden Town platform smelled of rust and something older—copper pennies left too long in a closed fist. Detective Harlow Quinn ducked under the police tape a constable had strung across the stairwell, though God knew how he'd justified stringing tape in a station that didn't officially exist on any current map. Off the books, this one. It had come in as a call about vagrants, then escalated fast enough that someone had thought to ring her directly. She understood why the moment she reached the platform edge. The body lay near the rail, a man in his fifties by the look of the hands, though the face was turned away toward the black mouth of the tunnel. Chalk-white light from portable lamps threw everything into harsh relief: the tiled walls, greened with age, and the strange scorch pattern radiating from the corpse like a child's drawing of the sun. "Cause of death, they're saying electrical," said DC Priya Bhatt, crouched a few feet off with her notebook balanced on her knee. She was solid, careful, the kind of officer Quinn trusted to get details right even when she got conclusions wrong. "Third rail's decommissioned, but maybe some kind of surge. Faulty wiring from whatever's been squatting down here running generators." Quinn didn't answer right away. She crouched at the edge of the scorch mark, close enough to feel the cold coming off the tile, and studied the pattern instead of the body. Burn radials didn't behave like that. She'd seen electrocutions—two, in eighteen years, both industrial accidents—and the char had always followed contact points, arms, hands, a foot braced wrong against a live rail. This was different. This was a perfect ring, six feet across, with the body at its center like the eye of a target, and untouched stone just past its edge, no gradual fade, no scatter. "Show me the wiring," she said. Bhatt gestured toward the tunnel mouth. "That's the thing. Structural came through an hour ago. Cabling down here's been dead since the seventies. No power source. No panel. Sparks reckon it might've been a portable generator someone dragged in and then took away again, but—" "But you didn't find one." "No, ma'am." Quinn stood, joints protesting the cold, and walked the ring's circumference slowly, the way she'd once walked a perimeter in Helmand, back before Vice, before homicide, back when precision meant the difference between finding the wire and losing a leg to it. Old habits. She still moved like she expected the ground to have opinions about her. At the ring's edge, she stopped. There, cut into the tile—not scorched, cut, clean as a chisel through butter—was a symbol she didn't recognize. A circle within a circle, bisected by three lines that met at angles no draughtsman would have chosen. She'd have called it graffiti except graffiti didn't sink half an inch into reinforced platform tile without leaving tool marks, dust, debris. This looked grown, not carved. "Priya. Photograph this before anyone tramples it." Bhatt came over, camera already up, and paused mid-motion. "That wasn't in the first sweep photos." "I know." "I mean it wasn't there, ma'am. I did the sweep myself twenty minutes ago." Quinn said nothing. She'd learned, three years ago, not to argue with the impossible in front of witnesses. Arguing only made you sound like DS Morris in the weeks before he vanished—increasingly certain of things no one else could see, increasingly alone in the certainty. She'd watched that happen to a good man and called it stress, called it the job, called it anything except what some small, cold part of her had started to suspect it actually was. She wasn't going to make his mistake of saying the word out loud before she had proof solid enough to survive a courtroom, or at least a chief superintendent. She crouched again, closer to the body this time, ignoring the smell, cataloguing. The victim's shoes were unmarked—no scorching on the soles, which any electrocution victim standing in that ring should have shown. His hands, though, were blistered along both palms, the skin cracked in thin white lines like the burn had come from inside the bone outward rather than from an external current entering through a limb. "Priya, when was he found?" "Eleven forty. Anonymous call, no name given. Said he'd heard 'something moving where nothing should be' and then screaming." "Was there a smell reported? Before the fire brigade came through with their equipment?" Bhatt checked her notes, frowning slightly at the specificity. "Caller mentioned ozone. And something sweeter. Thought maybe it was gas at first." Ozone and sweetness. Quinn had smelled that combination exactly once before, in the stairwell of a Bethnal Green council block three years ago, moments before DS Morris told her to wait outside and never came back down. She had told herself for three years it was chemical, industrial, explicable. She had built a whole career since on the discipline of not believing what her own memory kept insisting. "This wasn't an accident, and it wasn't a generator," Quinn said, straightening. "Whoever did this didn't need power. They brought their own." Bhatt gave her a careful look, the kind subordinates gave superiors who'd started saying things slightly too far past the evidence. "Ma'am, with respect—the sigil could be an existing marking we missed. Poor lighting, first sweep, could've overlooked it—" "You didn't overlook it, Priya. I believe you." Quinn looked down the black throat of the tunnel, where the tracks vanished into a dark that seemed, absurdly, to be looking back. "I think we're standing in someone's front door, and the man on the ground opened it without an invitation." She didn't say the rest—that she intended to find out who held the key, or that she had a growing, unwelcome suspicion the answer ran through a redheaded museum researcher and her too-convenient American friend, both of whom had crossed her desk twice now in contexts that should never have overlapped. She only crouched once more at the sigil's edge, close enough to feel that the cold there was different from the cold of the station—drier, cleaner, wrong—and thought, not for the first time since Morris, that some doors, once you noticed them, could not be unnoticed again.
