The call had come in at 4:12 a.m., and by half four Detective Harlow Quinn stood at the mouth of a stairwell that shouldn't have existed. Camden High Street lay quiet above her, the shutters down on the tourist shops, a fox picking through takeaway boxes near the lock. But here, wedged between a kebab shop and a shuttered tattoo parlour, a set of tiled steps descended into the earth. Cream and oxblood tiles, the old Underground livery, still bearing the ghost of a station name that had been chiselled away decades ago. Quinn had walked this street a thousand times. She'd never seen the steps. "Morning, guv." PC Adeyemi held the tape up for her, his face grey in the light of the arc lamps someone had dragged down. "Mind the fourth step. It's gone soft." "Soft." "Rotted through, or — I dunno. Just don't put your weight on it." She didn't. The fourth step gave off a smell like wet pennies as she stepped over it, and she filed that away with everything else she'd be filing away tonight. The platform below had been sealed since 1949 according to the log, which meant the fresh boot prints in the dust were a problem. Not a big problem. Just the first of them. Quinn crouched at the bottom of the stairs and swept her torch across the floor at a low angle, letting the beam rake the dust the way she'd been taught eighteen years ago by a sergeant who'd since retired to Margate and stopped answering her calls. Prints. Dozens. Coming and going. Most of them heading east along the platform, toward whatever lay past the reach of the lamps. None of them coming back. "You seeing this?" she called. "Seeing what?" DI Peter Vance came out of the dark with his hands in his coat pockets, which was exactly how he attended every crime scene and exactly why he'd never once found anything Quinn hadn't handed him. He was a good copper in the way a good gate is good. He kept things where they were put. "Footfall. All one direction." "They came in the other way." He nodded vaguely down the tunnel. "Service access. Probably a whole crew of them, urban explorers, that lot. They film themselves. YouTube." "There's no other way in. Adeyemi walked it." "Adeyemi's been in the job eleven months." Quinn stood, brushed her palms on her trousers, and started east. The platform stretched further than the geometry of the street above should have allowed. She counted her paces out of long habit — sixty, eighty, a hundred and twenty — and by ninety she'd stopped believing the count. The body lay in the centre of the platform, arms folded across the chest like something out of a chapel. That was the second problem. "Male, mid-forties," Vance said, coming up beside her. "No ID. No phone. Pathologist's stuck on the Blackwall Tunnel, be another hour. Looks like a fall to me. Cracked skull, blood pooled under the head, you can see it there." Quinn knelt. She did not look at the skull. She looked at the hands. "Guv?" "Whose interpretation is the fall?" "Mine. And it's not an interpretation, it's the obvious read. Bloke gets in here, wanders about in the dark, goes over. Happens more than people think." "He fell." Quinn tilted her head until her cheek was nearly against the tile. From that angle the pool of blood beneath the man's skull resolved itself properly — the edges of it, the way it met the grout lines. "And then he folded his own arms." Vance was quiet for a second. "Rigor. Rigor does funny things." "Rigor holds a position. It doesn't invent one." She took a pen from her inside pocket and used it to lift the cuff of the man's coat. Underneath, the shirt sleeve was clean. Immaculate. White as a dinner napkin. "Look at his sleeve." "So?" "So the floor's got seventy years of dust on it and he's lying in it and his cuff is spotless." She let the coat fall back. "He wasn't dropped here. He was arranged here. Someone knelt where I'm kneeling and put his arms like that, and they were careful, and they had clean hands." "Or he came down here clean and—" "Nobody comes down here clean." Quinn stood and swept the torch out in a slow arc. "Where's the dust disturbance? If he fell, he'd have skidded. There'd be a smear, a scuff, something. There's a body, and there's dust, and the dust isn't touched except by boots." Vance said nothing. Quinn walked a widening spiral out from the corpse, torch low, and it was on the third pass that she found the third problem. The boot prints stopped. Not thinned out. Not scuffed away. They walked east in their dozens — trainers, work boots, one narrow heel, a bare foot she didn't want to think about — and then, at a line as clean as a chalk mark, there was nothing. Beyond it lay six feet of virgin dust, undisturbed, grey and even as fresh snow. And beyond that, the tunnel mouth. "Peter. Come here." He came. She watched his face as he took it in, and she watched the exact moment his mind performed the little sidestep she'd seen a hundred officers perform at a hundred scenes — the flinch away from the thing that didn't fit. "Someone swept it," he said. "Swept it and left the dust perfectly level? With no broom marks?" "Then they came in on the tracks and climbed up." "Then their prints would start at the platform edge and walk inward." She pointed. "These walk outward and stop. They didn't come in this way. They went out this way. And then they weren't on the floor anymore." "Harlow." Vance rubbed his jaw. "Don't." "Don't what." "Don't do the thing you did with the Farringdon job." The name landed the way it always did, low in the ribs. Three years ago. A basement in Farringdon and DS Morris going through a doorway six feet ahead of her, and Quinn following four seconds later into a room with no exits and no Morris and a smell like wet pennies. She'd given eleven interviews. She'd stopped at eleven because the twelfth would have finished her. "I'm reading a scene," she said. "That's the job." "You're reading things into it." "I'm reading a man laid out like an offering on a platform that isn't on any map, in a station that's been sealed since before my mother was born, at the end of forty sets of footprints that walk into thin air." She crouched at the boundary line and held her hand flat above the untouched dust. The air over it was colder. Noticeably, particularly colder, the way air is over water. "Where's the door, Peter?" "There's no door." "There's a door." She moved her hand left. The cold followed, then dropped away. She moved it back. Cold again — a column of it, roughly two feet across, running from the floor to somewhere above her head. She traced the edge with her fingertips and felt the temperature step down and up like a threshold. "Two feet wide. Right here. And every one of those prints walks through it." Something in her coat pocket ticked. Quinn went still. She'd been carrying the brass compass for three years, since she'd taken it off a dead man's chain in Farringdon and never logged it, and in three years it had done nothing but sit there and turn green. Now the needle beat against the glass like a moth. She took it out. Held it flat on her palm. The needle swung, steadied, and pointed dead at the empty air in front of her — at nothing, at the cold, at the two-foot gap where forty people had stopped leaving footprints. Vance stared at it. "What is that?" "Evidence." Quinn closed her fingers around the brass. Behind her, the arranged man lay with his clean cuffs and his folded arms, and she understood, finally, what the folding meant: not reverence. Presentation. Someone had left him there to be found, the way you leave a note on a kitchen table. "Get Adeyemi. Get the tape moved back to the top of the stairs. And nobody — nobody — goes east of where I'm standing." "On what grounds?" She looked at the level, waiting dust. "On the grounds that whoever's on the other side counted us coming in."
