The ladder down into the old Tube station ran forty feet, and Harlow Quinn counted every rung out of habit. Her torch beam cut through air that tasted of rust and standing water. Somewhere below, blue evidence lamps threw their glow across tiled walls that hadn't held a train since 1932. "You took the stairs," called a voice from the platform below. DS Reyes stood at the bottom in a white scene suit two sizes too big for him, gloves half off, a coffee balanced on the barrier tape. He'd joined her team eight months ago and still hadn't learned that she took ladders the way she took everything else — without complaint and without hurry. "There are no stairs. There's a maintenance shaft and a rope." She stepped off the last rung onto the platform. "Who called it in?" "Nobody, that's the thing. Urban explorers found him." Reyes led her along the platform edge, past a rusted bench and a poster for a cinema that had closed before she was born. "Two kids with head torches came down around four this morning. They saw the lamps, legged it, rang it in from a phone box because one of them was on probation and didn't fancy explaining himself." "And the body?" "Round the curve. Mind the third rail, it's dead, but trip on it and you'll go into the pit." Quinn rounded the bend in the tunnel and stopped. The man lay on his back in the centre of the trackbed, arms at his sides, feet together. Mid-fifties, heavy build, dressed in a good coat gone shiny at the cuffs. His eyes were open. His throat bore a wound that should have emptied him. She crouched beside him. The cut ran clean across the throat, deep enough that she could see the cartilage of the windpipe glistening in her torchlight. She swept the beam across the trackbed around him. Across the rails. Across the gravel and the sleepers and the drainage channel. "There's no blood." "Forensics said the same. First thing out of their mouths." Reyes crouched opposite her, his suit crinkling. "Their theory is that he was killed somewhere else and dumped here. Which tracks with everything else. No drag marks, mind — that's the bit that's doing everyone's head in. He's just lying here like someone set him down with a crane." Quinn lowered her face to the level of the wound and breathed in. Copper, faint. Underneath it, something else — a sharpness, like the air after a lightning storm. She straightened. "Where's the blood he did have? A man this size, a wound like that, you're looking at three, four litres. You don't carry a body and lose none of it." "Maybe he was killed upright somewhere with a drain." Reyes shrugged inside the suit. "Honestly, guv, I think we're overcomplicating this. You know what this stretch of tunnel is used for. There's a whole network of squats and raves down here. He came down for a deal, someone opened his throat, panicked, and moved the body to the one spot nobody uses. Robbery with a bit of tidying up after." Quinn stood and walked a slow circle around the body, torch held low. "His pockets." "Turned out. Empty. So, robbery." "His watch is still on his wrist. Oyster card still in his coat. You don't take a man's pockets and leave his watch — that's a vintage piece, worth more than whatever cash he carried." She crouched again and lifted his hand with two gloved fingers. Rigor had come and gone. "And look at his fingers. No defensive marks. No bruising on the wrists, no fibre under the nails. He didn't fight. He didn't even put his hands up." "Some victims freeze." "Men this size don't. Not with a blade coming at their throat." She released the hand and set it back in position, then paused. "And he was arranged, Reyes. Look at him. Arms parallel, within a centimetre of each other. Feet together. Head centred on the body's axis. Robbers don't do that. Killers don't do that. Only two kinds of people lay a body out like this — the military and the religious, and this man's boots are fashion, not service." Reyes came to stand beside her and looked down at the body for a long moment. "Alright," he said. "What am I not seeing?" "Come stand where I'm standing. Torch off." "Guv—" "Torch off." He clicked it off. The evidence lamps threw hard blue shadows across the trackbed, and Quinn turned her own beam to the gravel beneath and around the body. "Look at the dust." She traced the light in a slow ring. "This tunnel's been sealed for ninety years. There's an even layer of dust and grit across the whole trackbed — except here. He's lying inside a clean circle. Perfectly round, about two metres across. And outside the circle, the dust is undisturbed for ten feet in every direction. No footprints. Not his, not ours, not the killers'. The first responders came in along the platform, so that's clean, but between the platform edge and this circle? Nothing." Reyes crouched, squinting. "That's not possible. Someone put him here." "Someone did. Without touching the ground." She rose and followed the circle's edge with her light until the beam caught something small at the margin, half-buried in the gravel. She knelt and worked it free with tweezers. A disc of bone, the size of an old penny, drilled through and strung on a leather cord. Carved into its face, worn smooth by handling, a symbol she didn't recognise — a closed eye with rays around it. "Uniform found three more of these in the tunnel," Reyes said. "In a niche in the wall, up near where the explorers came in. With candles. Melted all over the niche, big pools of it. Kids and their candles, I figured. Goths, satanists, whatever they call themselves now." "Candle wax runs and pools when you burn candles in a niche. Did the wax run?" "No. Flat discs of it, like they burned straight down with no draught at all." Quinn bagged the bone token and stood. She walked the circle's perimeter a second time, slower, and this time her light caught a mark on the tunnel wall — at shoulder height, on the curve, where the tiles had been scrubbed. She moved close. The grout between four tiles held a pale residue, chalky, and the tiles themselves bore faint scratches in a pattern too regular for decay. "Someone cleaned this wall. Recently. Within days — look at the grout, the chalk's still in the lines where a cloth couldn't reach." She photographed it, then pressed her palm flat against the tiles. Cold. Far colder than the tunnel air around it. She kept her hand there and looked back at the body, at the circle, at the scrubbed wall, and let the geometry of it settle into place. The circle. The body at its centre. The wall on the curve, dead ahead of the corpse's feet. "Reyes. Stand at his feet and look straight down the body's axis. Tell me what you see." He did. His torch travelled up the corpse, over the pointed toes, and landed on the scrubbed tiles. "It's directly in line with him. So?" "So he's not just arranged. He's arranged to point at something." She crossed back to the body and knelt at his side. In the gravel beside his right hand, pressed into the dust of the circle, lay an object the first responders had flagged but not moved: a small brass compass, its casing furred green with verdigris, its face etched with fine markings that no ordnance survey had ever printed. She lifted it by the edge and turned it in the light. The glass was intact. The needle was whole, balanced, free to move. It pointed at the scrubbed wall. She rotated in a full circle, holding the compass level, watching the needle. It didn't waver. It didn't hunt. It held its line on the wall with the fixed certainty of a needle that had found its north — except north was behind her, and she'd verified that against the platform's orientation before she'd reached the bottom of the ladder. "That's broken," Reyes said. "Needel's stuck." "Needles stick at a bearing. This one's tracking." She watched it. The needle trembled once, twice — a slow pulse, like breathing — then steadied. "Tracking what? There's nothing there. It's a wall." Quinn looked at the compass, then at the corpse laid out like an arrow, then at the chalk in the grout, and felt the cold coming off the tiles against her palm even from three feet away. Somewhere in the back of her skull, a memory she'd spent three years filing down to nothing — Morris, and the last case, and the thing she'd refused to put in her report — pushed itself up against the inside of the door she'd shut on it. "It's a wall that's two degrees colder than every other wall in this tunnel," she said. "It's a wall somebody scrubbed clean of markings within the last few days. And it's a wall that a dead man was laid out to face, in a tunnel that a bone token gets you into." Reyes stared at her. "A bone token gets you into a tunnel?" Quinn held up the evidence bag with the carved disc in it. "Four of these in a niche, candles burned flat, a body with no blood in it, no footprints around it, and a compass that doesn't care where magnetic north is." She pocketed her torch and pulled her gloves tight. "Get forensics to bring a thermal camera down here and point it at that wall. And Reyes — nobody leans on it. Nobody taps it. Nobody so much as breathes on it until I say so."
