The ladder down into the old station ran forty feet, and every rung rang like a struck bell in the dark. Detective Harlow Quinn counted them out of habit. Forty rungs, then her boots found the platform, and the smell hit her: rust, wet concrete, and underneath it something colder, like the air over a frozen pond. "Down here, ma'am." A constable's torch beam wobbled at the far end of the platform. Quinn walked. Her torch swept the curved tunnel walls, tiles the colour of old teeth, a roundel sign so grimed with decades that only the ghost of the station name survived: CAMDEN. The track bed had been drained years ago, but water still wept down the walls in long black streaks. The body lay in the mouth of the northbound tunnel. Male, fifties, grey suit that had cost more than her monthly salary. One arm flung across the sleepers, legs straight, eyes open toward the ceiling. No blood. No wounds she could see from three feet away. DS Iyer crouched beside him, gloved hands hovering over the chest. Young, sharp, still at the stage where he narrated everything he did. "Hypothermia, most likely," Iyer said. "Doc puts time of death between one and three this morning. Body temp's consistent with cold exposure, and it's bloody freezing down here. He's a rough sleeper, dressed nice for one, but rough sleepers end up in odd kit all the time. Wandered in through the maintenance access on the surface, got lost in the dark, sat down, and that was that." Quinn crouched opposite him. The dead man's shoes were Oxford leather, soles barely scuffed. She pressed the back of her glove to his cheek. Cold. Too cold. "It's June," she said. "Temperature drops like a stone in these deep tunnels. No airflow, the concrete pulls the heat out of—" "Sixteen degrees down here. I checked the surface access on my way in. It's a mild night." She lifted the man's hand. The fingers were stiff, and something white showed between them. She worked it free with tweezers and held it to the torchlight. A token. Carved from bone, the size of a pound coin, a hole bored through the middle. Symbols ringed its edge, worn smooth by handling. Iyer leaned in. "Domino? Some kind of game piece?" "Dominoes aren't carved from bone with sigils on them." She bagged it. "And rough sleepers don't freeze to death clutching them." "Maybe he collected oddities. You get magpie types." Iyer stood, brushing grit from his knees. "Honestly, ma'am, the simplest read is exposure. Doc agrees. There's no sign of assault, no defensive wounds, wallet's gone but that's scavengers, or he dropped it. Tragic, not suspicious." "Then explain the dust." Iyer blinked. "Sorry?" Quinn swung her torch low across the track bed. The gravel between the sleepers carried a fine grey silt, undisturbed, a smooth grey carpet running the length of the tunnel. The dead man's shoe prints started three metres from the body. She walked back along them, Iyer trailing behind, and the prints simply stopped. Two clean impressions, heel and toe, and then nothing. No drag marks. No scuffing. Just silt. "He walked to that spot," Quinn said, "and then he was sitting where he is now. How does a man walk three metres without touching the ground?" "Kids come down here. Urban explorers. They could have—" "Trampled it everywhere. They didn't." She crouched at the last footprint. "These prints don't approach the body. They leave it. Direction of travel's readable from the tread — he was walking toward the platform." Iyer's jaw worked. "That's not possible." "No. It isn't." A voice echoed down the tunnel from the platform, high and breathless. "Hello? Detective Quinn? It's Eva — Eva Kowalski? From the museum? Your office rang the archives at some ungodly hour and said you needed—" "On the track bed, Miss Kowalski. Mind the gap." Boots crunched on gravel and a small figure picked her way toward them, curly red hair escaping under a hard hat, a leather satchel banging against her hip. She had a torch strapped to the satchel's strap like a caving lamp, round glasses fogging at the edges. Eva stopped at the body and went very still. Then she looked past it, up the tunnel, into the dark. "You found him here?" she said quietly. "Who's this?" Iyer asked. "Consultant," Quinn said. "Miss Kowalski works restricted archives at the British Museum. My office sent photographs of the token down to the antiquities desk this evening. She recognised the carving." "Recognised is generous." Eva pulled a folded printout from her satchel and opened it against her knee: a photograph of a clay tablet, cuneiform and something older, and along its lower edge the same ring of symbols as the bone token. "This is a warding script. Pre-Roman, possibly older, and the reason it's in a restricted archive is that every documented example was found at sites with unexplained deaths. The script marks thresholds. Boundaries. Places where the world is thin." She tucked a curl behind her left ear. "It's not a game piece, and whoever carved it wasn't playing. It's a key." "A key to what?" Iyer's laugh came out thin. "It's a disused Tube station." Eva didn't answer. She was staring at the wall. Quinn followed her gaze. The tunnel wall here ran with condensation, except for one patch, a metre across, dry as chalk. She crossed to it and laid her palm flat against the tiles. Cold bit through her glove, sharp enough to make her hiss. Frost feathered out from her fingers. "It's June," Iyer said again, weaker this time. Quinn searched the dead man's pockets, working methodically while Eva's lamp lit the body. Inside pocket: a return ticket to Camden, dated today, unused. Trouser pocket: a small brass compass on a chain, its casing green with verdigris, its face etched with the same symbols as the token. The needle was spinning. Not swinging. Not hunting. Spinning, smooth and constant, like a fan blade. "That's broken," Iyer said. Quinn held the compass level and turned a slow circle. The needle ignored her, ignored north, ignored every direction — except one. Each time she rotated the casing, the needle swung back to the same bearing. She sighted along it. The dry, frosted patch of wall. "He came down here with a ticket he never used and a key he never spent," Quinn said. "And these prints don't approach the body because he didn't walk out. Something put him out." She looked at the frost-rimed tiles, then at the token in its evidence bag, and the etchings matched, symbol for symbol, the sigils on the compass face. "He was turned away at a door we can't see. And tonight's a full moon." Eva's head came up sharply. "How did you know that matters?" "Three years ago my partner died in a cellar in Whitechapel with no wounds, no toxins, and a room temperature of thirty degrees." Quinn kept her eyes on the wall, on the frost crawling in slow ferns across the tiles. "The report said cardiac arrest. The report was wrong. He had a bone token in his hand too, and nobody would tell me what it was." She turned the compass over in her gloved palm, watching the needle strain toward the wall like a dog at the end of a lead. "I stopped believing in coincidence around the same time I stopped believing in that report. This man wasn't lost, Iyer. He was a customer. And whatever market he was shopping at doesn't give refunds."
