The stairs went down farther than they had any right to. Harlow Quinn counted them without meaning to, a habit from her Army years, when knowing how many steps lay between you and daylight had seemed like a sensible thing to keep in your head. Eighty-one. At the bottom the tiled passage bent left and the air changed. It was cold and mineral, the kind of cold that had been sitting in one place since the Blitz and resented being disturbed. Somebody had strung work lights along the ceiling. They buzzed. Beyond them, the old platform of a station that had not appeared on any Tube map in her lifetime opened out under a vaulted ceiling crusted with soot. Cream and oxblood tiles, most of them cracked. A faded roundel with half its letters gone. Down on the trackbed, rails rusted to the colour of dried blood. And in the middle of the platform, a man lay on his back with his arms folded neatly across his chest, as if someone had tucked him in. "Guv." DS Dominic Haines peeled himself away from the tiled wall, where he'd been talking to a uniform. He was thirty, earnest, and very tired, and he held a paper cup of coffee that he had clearly carried down all eighty-one steps as a matter of survival. "Sorry to drag you out. TfL engineer found him at half six doing a flood survey. Thought you'd want a look before the pathologist moves him." "Why would I want a look?" "Because it's weird, and you like weird." He had the grace to look sheepish. "But honestly, I don't think there's much here. Rough sleeper. There's a gap in the grille at the Camden Road end that you could fit a pushchair through. He comes down to get out of the cold, takes whatever he takes, and doesn't wake up." Quinn didn't answer. She stood at the edge of the lights and looked at the floor first, because the floor was the one witness that never lied on purpose. Dust. Decades of it, soft and grey as ash, lay across the platform so thickly it held a print like snow. She could read the morning in it easily enough. There was the engineer's boot tread, heavy and wandering. The uniforms had trampled a path in. Haines had come in his cheap brogues with the worn left heel, and he'd gone to the body, back to the wall, and to the body again. That was all. "How did he get to where he's lying?" she asked. Haines followed her eyes. "Sorry?" "The dead man. Where are his footprints?" He looked down at the dust, and then at the body fifteen feet from the nearest trodden path, and she watched him work at it. "Maybe the engineer walked over them." "The engineer walked in a straight line from the stairs to within ten feet of the body and then ran away. I can see where he turned." She pointed. The scuffed half-moon of a man pivoting on his heel. "Nobody has walked to where that man is lying except you. Did you carry him in?" "No, obviously I didn't—" "Then he didn't walk in either." She took the overshoes from her coat pocket, pulled them on, and walked Haines's path out to the body. She crouched on her heels with her forearms on her knees and her hands clasped so she wouldn't touch anything before she meant to. The dead man was perhaps sixty. He had a grizzled beard and a wool coat gone shiny at the elbows. His face was grey and peaceful. His hands were folded right over left, and the right hand was closed around something. His shoes were clean. Not polished, not new. Just clean. There was no grey powder in the welts and no dust on the soles, where she could see them tipped towards the ceiling. She glanced at the rim of the platform, at the rails furred with rust, and back again. "Rough sleeper," she said. "The coat," Haines offered. "The beard." "There's a laundry tag on the inside of his collar. It's a dry cleaner in Hampstead. His nails are trimmed. There's a callus on the second finger of his right hand, the kind you get from a fountain pen." She tilted her head. "Rough sleepers don't dry-clean." "People fall on hard times, guv." "They do." She didn't look up. "But they don't levitate onto platforms." She looked at the dust again, not near the body this time but past it, along the length of the platform. The work lights threw everything flat, so she took out her torch and laid it on its side against the floor, the way Morris had taught her a lifetime ago. The low beam skated across the grey. And the floor stood up out of the dark. Rectangles. Dozens of them, laid out in two long rows down the platform, as clean-edged as if someone had lifted furniture away. Where the rectangles lay, the dust was thin, a fine skin a day or two deep. Around them it lay decades thick. Between the rows ran a long pale lane, worn smooth by a great many feet, all of it somehow gone quiet, with not one individual print left to read. She moved the torch. There were little hard spatters in the dust, dozens of them. She pressed one with a gloved fingertip. Wax, black and still faintly soft. "Dom," she said. "When was the full moon?" "What?" "The full moon. When was it?" He blinked at her, then pulled out his phone, because Haines was a good officer who did what he was told even when he thought his DI had lost the plot. "Last night. Why?" She didn't answer. Something cold had settled low in her stomach, and it wasn't the air. There had been a market here. Stalls had been standing in rows, lit by candles, busy enough to wear a lane in the dust. Then all of it had been lifted away sometime in the night, so cleanly that the floor itself seemed to have forgotten the feet. The only thing they had left behind was the man. "Help me with his hand," she said. The fingers were stiff and cold, but they opened. In his palm lay two objects. The first was small and yellowish-white, about the length of her thumb joint, carved all over with tiny cramped marks. She turned it under the torch. It was bone. It was a knucklebone, and she didn't want to guess what animal it had come from. The second was a compass. It sat heavy in her palm. The brass casing was pocked green with verdigris at the hinge, and the glass was scratched but whole. Around the face, in place of the cardinal points, ran a border of etched symbols. They were angular and interlocking, and they made her eyes want to slide off them. Some of them she half recognised, and she could not have said why. The needle was not pointing north. She knew where north was. She'd had it in her head since the eighty-first step. North was up the line towards Kentish Town. The needle pointed hard to her left, trembling, straight at the tiled wall behind the bench where the uniforms had been standing. She turned the compass through ninety degrees. The needle swung back, steady and patient, to the wall. "That's a nice bit of kit," Haines said, peering over. "Antique, is it? Maybe that's the motive. Robbery gone wrong. They panicked and ran before they could take it." "They carried him fifteen feet across a dusty floor without leaving a mark, folded his hands, then panicked and ran." Quinn stood. Her knees cracked. "Bag the bone. I'll take the compass." "Guv, it needs to go into—" "I said I'll take it." He shut his mouth. She hated herself a little for the tone, and not enough to take it back. She walked to the wall with the compass held flat before her. The needle stayed fixed on one spot. It was a section of cream tile no different from the rest, except for a hairline seam running down it. The seam was so fine she wouldn't have seen it without the torch. When she held her palm an inch from the tile she felt the air moving. It was faint and cold and it breathed through a gap too narrow for a coin. She knew that smell. It was like struck matches and the air after lightning. It had been three years. There had been a warehouse off the Old Kent Road and a door that shouldn't have been there. Morris had gone through it ahead of her, laughing at something she'd said, and never come back out. The report said structural collapse. The report said a lot of things, and she'd signed it, because there'd been nothing else to sign. "Guv? You all right?" "Fine." Her voice came out level. Eighteen years in the job had taught her that much. "Search his pockets properly this time. All of them. Linings too." Haines crouched and went through the coat with more care than before. After a minute he made a small sound. "Found something. Inside pocket, folded up small." He held it out between two gloved fingers. It was a slip of printed paper, soft from handling. "Looks like a request form. British Museum. Restricted archives, reading room access." He squinted. "Authorised by E. Kowalski, research assistant. Dated last Thursday." Quinn took the slip and read it twice. The signature was quick and round-lettered, the kind you'd get from someone who wrote a lot of notes very fast. E. Kowalski. She checked her watch. The worn leather strap was stiff with cold. It was quarter past eight. The museum would open its staff doors in forty-five minutes. Behind her the needle of the compass held its line on the seam in the wall, trembling slightly, like something that was waiting. "Get the pathologist down," she said. "Nobody touches that wall. Nobody. I want a uniform on the stairs until I say otherwise." "Where are you going?" Harlow Quinn slid the compass into her coat pocket, where its weight settled against her hip. "To the library," she said, and started to climb.
