The stairwell smelled of iron and cold water, which was wrong for August. Quinn took the steps down slowly, one hand off the rail, her torch beam sliding over tile the colour of old teeth. Sixty-eight feet of Victorian brickwork between her and the noise of Camden High Street, and by the fortieth step the noise had stopped entirely. No traffic. No sirens. Just her boots and the drip. "Mind the ninth one from the bottom," a voice called up. "It's got a wobble on it." "Prewitt." "Guv." Detective Sergeant Ollie Prewitt stood on the platform in a paper suit two sizes too generous, hood down, hair stuck flat to his forehead. He held a clipboard like a shield. "You didn't have to come out. It's a body in a hole in the ground. We've got four of those a year." "Where is he?" "She. Northbound end, past the tunnel mouth." Prewitt fell in beside her. "Female, mid-thirties, no ID, no phone. Some kid with a GoPro found her at half four this morning, then had a crisis of conscience and rang it in from a chicken shop on Kentish Town Road. He's in the van, crying." Quinn stepped out onto the platform and let the torch travel. The station had been sealed since 1924. She'd read that on the drive over, on her phone, at a red light — South Camden, closed for low passenger numbers, the surface building converted to a sandwich shop, the shafts capped, the lift wells filled with rubble. Ninety-nine years of nothing. There should have been a carpet of dust on the platform thick enough to leave a bootprint like wet plaster. There was dust. But it lay in a strange geography, and Quinn stood at the tunnel mouth for a long moment looking at it. "Blood's minimal," Prewitt said. "There's the story right there. No arterial spray, no drag marks, nothing under her fingernails. She came down here to use, she used, her heart packed in. Happens all the time in the deep shelters. We had one in Aldwych in March." "How did she get in?" "Vent shaft on Buck Street. Grille's been cut and re-hung so it looks intact — the urbex lot do it all the time, they call it a soft lock." He tapped the clipboard. "Explorers, guv. She'll be on somebody's forum with a username." "Show me her hands." The body lay on her side in the recovery position, which was the first thing that made Quinn's jaw tighten. Nobody dies neatly. People die in the shapes their last few seconds allow — sprawled, folded, one arm trapped behind the back. This woman lay with her knees drawn up and her cheek resting on her own forearm, hair swept off her face. Quinn crouched. She didn't touch anything. She never did, not first. "Skin's cold," Prewitt offered. "Pathologist reckons ten, twelve hours." "Lividity's in her shoulder and her upper arm." "Right. She's on her side." "She's on her left side. The pooling's in her right." Quinn moved her torch along the line of the body, slow as a scanner. "She spent the first four hours after death lying on her right, somewhere else, and then someone rolled her over and arranged her here. Look at her collar." Prewitt leaned in. "It's tucked." "Someone tucked it. Someone straightened her jumper, put her hair back, and folded her hands." Quinn's beam settled on the woman's boots. "Now tell me about those." "They're boots." "They're clean, Prewitt." He stopped. He looked at his own paper overshoes, grey to the ankle, then at the sole of the dead woman's right boot — the tread packed with nothing at all. No brick dust, no rust flakes, no ninety-nine years of tunnel silt. "She could've been carried," he said. "Sixty-eight steps and a cut grille. Carried by whom? Where are their prints?" Quinn stood and swung the torch out across the platform. "Answer me that first, then answer me this." The beam picked out the floor between the tiled wall and the platform edge. In that strip of ground the dust had been scuffed to a polish — thousands of overlapping impressions, feet on feet on feet, the way the concourse at Euston looked after a wet rush hour. Boots, bare soles, something with three toes and a heel like a horse's. The traffic ran the length of the platform, a broad churned river of it. And it stopped. Nine feet from the wall at the northbound end, the churn ended in a line so clean it might have been drawn with a straight edge. Beyond that line: undisturbed dust, ninety-nine years of it, soft as fur. "Well," Prewitt said, "that's the vent shaft crowd, isn't it. They come down here for raves. There's probably a hundred kids been through in the last month." "A hundred kids who all walk up to that wall, turn around and walk out again, and none of whom step in the last nine feet of the platform." "Maybe there's a drop. A hole." "There isn't." Quinn walked the line. She kept her boots on the clean side, out of habit, out of respect, and let the torch rake the wall. Old advertising tile, cracked, a ghost of a hand-painted arrow. And low down, at knee height, a mark in chalk — not graffiti, no tag, no signature. Two arcs and a bisecting stroke, drawn with the deliberate slowness of someone who'd done it a thousand times. Fresh chalk. It smudged under her breath. "Prewitt. Get SOCO to photograph and lift this." "Lift a chalk drawing?" "Yes." He wrote it down, mouth pressed thin, the way he did when he was banking a complaint for later. Quinn came back to the body and crouched again, and this time she took a pen from her jacket and used the barrel of it to open the dead woman's right hand. The fingers had gone stiff around something, and the something had pressed a shape into the palm. Bone. A flat oval of it, yellowed, no bigger than a fifty-pence piece, drilled through at one end and carved with the same two arcs and bisecting stroke as the wall. "Token of some kind," Prewitt said. "Club entry? There's a place on the canal does bone jewellery." "Her nails are manicured. Her jumper's cashmere. She's wearing a wedding ring worth more than my car." Quinn tilted the token with the pen so the light caught the carving. "Women like this don't come to South Camden at midnight for a rave. They come because they've got an appointment." Something in the woman's coat pocket clicked when Quinn's pen touched the fabric. She eased the pocket open. Brass, green with verdigris, the size of a pocket watch. A compass, its face crowded with etched marks — the same alphabet as the chalk, the same as the bone. Quinn turned the casing so the needle sat free. The needle didn't find north. It swung a slow half-circle, hunted, and settled hard, pointing at the blank wall nine feet away. Quinn held it up. Turned her wrist ninety degrees. The needle held its bearing on the wall, quivering like a dog on a scent. "Compass is knackered," Prewitt said. "All that iron in the rails." "The rails are behind me." "Guv—" "Three years ago," Quinn said, and her voice came out flat and low, "DS Morris walked into a stairwell at Brompton Road and he came out with his hair gone white and no memory of six hours. There was chalk on his sleeve." She closed the compass. "Two arcs and a stroke. I've got the photograph in a box under my desk." Prewitt said nothing. Quinn looked from the tidy body to the tidemark of footprints, to the fresh chalk, to the nine feet of dust that a thousand feet had refused to cross. "They didn't come in through the vent," she said. "They came out of that wall. And she was the only one who came out of it dead."
