The stairs went down farther than they should have. Harlow Quinn counted them without meaning to, a habit from her Army years that had never quite let go. Ninety-four steps, iron-edged and slick with a century of damp, spiralling past tiles the colour of old teeth. Somewhere around sixty the air changed. It stopped smelling of Camden, of diesel and fried onions and the canal, and started smelling of nothing at all. That bothered her more than rot would have. At the bottom a uniformed constable lifted the tape for her. He looked about nineteen and grey around the mouth. "Ma'am. DS Reyes is on the platform." "How long have you been down here?" "Since four, ma'am." He hesitated. "It's cold, isn't it? For August." It was. Her breath hung in front of her when she answered him, and she could feel the chill working through the wool of her coat. She checked her watch, the worn leather strap stiff against her left wrist. 6:52 a.m. She filed the temperature away and walked on. The platform opened in front of her like the inside of a lung. Arc lamps on tripods threw hard white light across the curved ceiling, and the tunnel mouths at either end swallowed it whole. The station had been sealed since the war, according to the TfL file on her phone. Nobody had come down here in eighty years except rats and the occasional urban explorer with a GoPro and more nerve than sense. The dead man lay near the platform edge, on his back, arms at his sides. Callum Reyes stood over him with a coffee in one gloved hand and an expression of settled boredom. He was younger than Quinn by a decade, good at his job in the way that people are good at jobs they have decided not to find interesting. "Morning, guv. Sorry to drag you out." "You didn't. The Super did." She stopped two metres from the body and did not go closer. "Talk." "White male, forties. No ID, no phone, no wallet. Explorer found him about three-thirty and nearly had a coronary. Doc's had a first look. No obvious trauma, no ligature marks, nothing under the nails." Reyes shrugged. "My money's on an overdose. He's come down to use, or somebody's brought him down to party, it's gone wrong, and his mates have legged it and taken his stuff. We get a couple of these a year in the old stations." "Down ninety-four steps." "People do strange things when they're high." Quinn crouched. The victim wore a charcoal suit, well cut, and the kind of brogues that cost more than a constable made in a week. His face was calm. His eyes were open, and there was a thin rime of frost in the lashes. "Doc say anything about that?" Reyes followed her look and his mouth tightened, just slightly. "Said it was odd. Said the core temperature was odd, too. Lower than it should be for the time frame." He waved the coffee at the tunnel. "It's cold down here. Draughts." "It's cold," Quinn agreed. "It isn't freezing." She stood and turned a slow circle, letting her eyes adjust to what the lamps showed and what they didn't. The first thing she noticed was the dust. It lay thick across the platform, grey and soft as ash, and in the arc light it took footprints the way snow did. She could see her own trail coming in from the stairs, and the constable's, and Reyes's, and the scuffed arc where the doctor had knelt. Four sets. Five, counting the explorer, whose trainers had left a frantic zigzag that ended at the body and fled back again. There were no other prints near the dead man. None. "How did he get here, Callum?" "Walked." "Show me." Reyes looked down. She watched him see it, watched him start to build the explanation before he'd fully understood the problem. "He's been carried. Or he came in from the tunnel side." "The tunnel side is a two-foot drop onto the track bed. There's dust on his trousers, but only on the back, where he's lying in it. There's none on the knees or the cuffs." She pointed with her chin at the brogues. "And look at his soles." The soles were clean. Not polished, but clean, the way shoes were when a man had walked on pavement and carpet and nothing else. No grey on them at all. "So he was carried," Reyes said. "Then where are the carrier's footprints?" He didn't have an answer for that. He drank some coffee instead. Quinn moved away from the body and walked the length of the platform, keeping close to the wall. Out here, beyond the ring of disturbed dust around the crime scene, the surface was smooth, almost pristine. Almost. Every few metres she found a small round mark, a dimple in the grey the size of a two-pence piece, with a drip of something hard and pale at its centre. She crouched and touched one with a gloved fingertip. Wax. Tallow, by the smell of it, animal fat, the kind nobody had burned in London for a hundred years. The dimples ran in a line. Then another line, parallel, three metres further out. She paced it. The rows ran the whole length of the platform, evenly spaced, like the outlines of stalls at a street market. Like somebody had set up shop down here, with hundreds of candles, and then lifted every trace of themselves out of the dust except the candle drips. A memory rose, uninvited: Morris on a stairwell in Deptford three years ago, calling up to her that the door at the bottom was cold to the touch. The last thing he'd said to her. The inquest had called it misadventure. Quinn had never once believed it. She put the memory back where she kept it and kept walking. "Guv." Reyes had followed her. "The doc found something in his hand. I bagged it. Didn't think it was relevant." He held out an evidence bag. Inside was a compass, small and brass, the casing gone green at the seams with verdigris. Someone had etched the face with symbols, dense looping marks that weren't letters in any alphabet Quinn recognised. They looked less like decoration than like instructions. "Antique," Reyes said. "Probably nicked. Probably what he was going to sell for his next fix." Quinn turned the bag in the light. The needle didn't point north. She knew roughly where north was; the stairs had come down facing it. The needle pointed across the platform, toward the far wall, and when she stepped left, it stayed fixed on the same spot. When she stepped right, it swung to keep it. "Callum. Which way's north?" He pointed. Correctly. She held up the compass so he could see the needle pointing the other way. He looked at it for a long moment and said, "It's broken." "It's not broken. It's pointing at something." She followed it. The far wall was tiled like the rest, cream and oxblood, with the station's name picked out in a mosaic panel that had lost half its letters. The needle led her to a patch just to the left of the panel, a stretch of tile no different from the tiles around it. Except that when she held her palm an inch away, she felt heat coming off it. Not warmth. Heat, like standing near a radiator, in a station where her breath still smoked. She took her glove off and touched the tile. It was smooth and almost hot, and beneath her fingers, very faintly, she felt a vibration, the way a window hums when a lorry goes past outside. There was no lorry. There was nothing above them but eighty feet of London clay. "Guv?" "Get the explorer back in. I want to know exactly what time he came down, and I want to know if he saw lights." "Lights?" "Candles. People. Anything." She pulled her glove back on, flexing her fingers against the lingering heat. "And find out when the last full moon was." Reyes gave her a look she'd seen before, from colleagues, from her Superintendent, from the Federation rep after Deptford. "Harlow, with respect—" "This man didn't walk in here and he wasn't carried in. Somebody ran a business on this platform last night, a big one, and cleaned up behind them better than any forensics team I've ever worked with. He died in the middle of it, and they left him because they couldn't take him where they were going." She looked back at the wall. "And they went through there." "That's a wall." "Then why is it warm?" He didn't answer. She walked back to the body. Something else was nagging at her, and she crouched again and looked at the dead man's suit, at the inside breast pocket, which sat slightly open. Reyes had said nothing on him. Reyes was usually thorough, but Reyes had decided this was an overdose before he'd even seen the brogues. With two fingers she drew the pocket wider. Tucked into the lining, where the stitching had come loose, was a slip of card. She eased it out. It was a reading-room request slip, the kind the British Museum used for its restricted collections. The requested item was a catalogue number she didn't recognise. Under *Authorised by* someone had signed in quick, looping ballpoint, the letters slanting hard to the right. *E. Kowalski.* Quinn knew that name. She had written it in her notebook six weeks ago, in a list of five names, beside a photograph of a curly-haired redhead in round glasses tucking her hair behind her ear on the steps of a Camden pub while her friends laughed around her. Behind her, on the far wall, she thought the tiles hummed a little louder. She slid the slip into an evidence bag and sealed it, and for the first time since coming down those ninety-four steps, Harlow Quinn felt something warmer than the cold. It wasn't comfort. It was the old, clean feeling of a thread pulled taut.
