The tape across the station entrance flapped in the wind off Camden High Street, and Detective Harlow Quinn ducked under it without breaking stride. The old Tube station hadn't seen passengers since the eighties. Now it had a body. DC Ferro caught up with her on the stairs, torch beam jittering over tiles furred with soot. "You're going to want to see this before the techs trample it any worse." "How many techs?" "Four." "Then it's already trampled." Quinn's boots found the bottom step. The platform stretched out in the dark, and somewhere past the tiled arch at the far end, somebody had strung work lights. Their glare pooled yellow on the concrete. The dead man lay in the middle of that light, on his back, arms at his sides like a man in a display case. Expensive coat. One shoe missing. Face calm to the point of serenity. "Callum Marsh, forty-seven. Property developer. Wife reported him missing nine days ago." "Nine days." Quinn crouched at the edge of the light, hands in her pockets, and let her eyes do the walking. "So he's been down here since at least Tuesday." "Guessing so." "Guessing is how innocent people go to prison." She leaned closer. No bloating. No smell beyond the station's own damp-iron breath. A body nine days dead in a warm, enclosed space should have announced itself to half of Camden. Ferro crouched beside her. "Cold down here. Slows things." "Not this much. Not unless he was refrigerated, and there's no fridge in an abandoned station." Quinn circled the body slow. "Look at his hands. Clean. A man who crawls into a derelict tunnel picks up filth. His soles — well, sole. Where's the other shoe?" "Dog walker found it a mile off, near the canal. That's what puts him here, trail leading down." "Or someone walked that shoe along the canal and dropped it for us to find." Quinn stopped at the man's head. "And this. Look at the hairline. There's a dust shadow, an outline, like he wore something over his face. A hood, maybe. Or a mask." "Kidnappers hood their victims. Not news." "Then they kept the hood on for nine days and fed him, because there's no lividity on the face and no petechiae from suffocation." She straightened. "He wasn't strangled, smothered, stabbed, or shot, and there's no bruising at the wrists or ankles. Nobody held this man against his will. He sat down and died." Ferro shone her torch along the platform, over to the arch at the far end. Chalk marks climbed the tiles there — a spiral of them, careful and repeated, worn glossy in places like a door handle. "Ferro. How long has that been there?" "Techs think it's old. Street art." "Street art doesn't get polished." Quinn walked to the arch and ran her thumb along one of the marks. White, waxy, half worn away, and beneath the chalk the tile itself was discoloured — heat damage, the kind you see on the back of a toaster. The whole spiral had been baked into the wall a few degrees at a time, over and over. "Something came through here. Repeatedly." "Through a wall." "Through an arch in a station that closed forty years ago, where a man in a good coat sat down, took off one shoe, put something over his face, and died with a smile." She turned back to the body. "What's in his pockets?" "Ferro handed her an evidence bag: a wallet, cash untouched. A folding knife, expensive, never used. And a brass disc the size of a pocket watch, green with age, glass scratched nearly opaque. "What's this, a compass?" Quinn tipped it into her palm through the bag. The needle under the scratched glass should have been rattling loose or stuck. Instead it held steady, dead level, pointing not north but sideways — straight through the tiled wall of the arch, into solid earth. "That's broken." "That's pointing." Quinn turned a slow half circle. The needle swung with her, always insisting on the same patch of wall. She looked at the chalk spiral, then the compass, then the spiral again. "Whoever he was, he wasn't down here to vandalise. He came with an instrument to find something, and then he found it." "A hole in a wall." "Nine days missing and no decomposition, which means either our pathologist is about to embarrass herself or time moved differently for him down here. Take your pick." "You're talking like a nutter, guv." "I'm talking like someone who's read the file on the Holloway case. Remember it? Three years ago. My partner found what was left of DS Morris under similar conditions, and I spent eighteen months being told the evidence didn't add up because I was emotional and grieving." Her watch glinted as she crouched again, checking the dead man's wrist. Nothing. Left wrist bare, right wrist bare — except for a pale band of skin, wider than a watch, lower down, closer to the hand. "He wore something on his arm. Removed before death or after. Not a watch — wrong placement." "Robbery?" "Robbers don't take a bracelet and leave four hundred quid." The needle of the compass twitched. Quinn felt it through the bag more than saw it — a tremor, like a dog waking. She held it flat and watched the needle swing a hard right, toward the stairs, toward the street, then stop mid-arc and steady on a new heading: deeper into the station, down the dead tunnel past the arch. "It's tracking something. It was tracking the wall, and now it's tracking something that moved." "Guv—" "Get everyone away from that tunnel. Now." Quinn was already walking, compass flat in her palm like a waiter's towel. "And put a call through to the British Museum. Restricted archives. Ask for anyone who studies—" She paused at the mouth of the dead tunnel, where the air ran colder than it should and smelled faintly of struck matches. "—ask for anyone who studies things that shouldn't exist." Ferro's radio crackled behind her, and far down the black throat of the tunnel, the needle swung again — toward something coming.
