The stairwell smelled of iron and wet chalk, and Quinn had learned a long time ago to trust her nose before she trusted anyone's statement. She came down the spiral in her own light, the beam sliding over ninety-four years of soot. Somewhere above, Camden High Street was still shouting itself hoarse at four in the morning. Down here the noise arrived as pressure in the ears, nothing more. "Watch the seventh step from the bottom," DC Pike called up. "Tile's loose. I nearly went the same way he did." "He didn't go any way." Quinn stopped six steps short of the platform and crouched, elbows on her knees, watch face catching the torchlight. "Guv, he's at the bottom of a staircase with his skull open. There's a fairly popular theory about how men end up at the bottom of staircases." The body lay on the platform edge, one arm folded under, the other flung out with the fingers curled toward the tunnel mouth. Male, sixties, wool overcoat worth more than Pike's car. Blood had pooled and then crept along a groove in the concrete, following the camber toward the rails. "Name?" "Wallet says Gerald Ashcombe. Antiquarian bookseller, Bloomsbury. Alarm company flagged the shop door at half one, uniform found it open and empty, then a member of the public rang in about lights down here." Pike thumbed his notebook. "Best guess, he's had a bad night, come down here to score or to hide, misjudged the stairs in the dark. Head wound's consistent." "Consistent." Quinn came down the last steps without touching the handrail and stood over the man. "How much dust is on the platform, Pike?" "Loads." "Thirty-odd years of it. Nobody's swept since eighty-nine." She swung the torch low and flat, the way you'd read frost on a windscreen. The beam raked the floor and turned the dust into a landscape of ridges and hollows and prints. "Count the shoes." Pike squatted. His mouth moved. "That's — a lot." "Forty-one distinct impressions. I've walked six of them coming in and you've made about fifteen wandering around like a Labrador." Quinn traced the air above a line of them with her finger. "Which leaves twenty. Different sizes, different treads, one bare foot with six toes that we're going to come back to later, and every last one of them going that way." She pointed the torch down the platform to where the tiling gave way to a blank wall of cream and oxblood glaze, an advert ghost still legible on it: DRINK MAZAWATTEE. "So they left up the other stairs." "There is no other stairs. This station has one shaft and it's been capped since the war. I checked the drawings before I got in the car." Pike stood, brushing his knees. "Then they came back out this way and their prints are in the mess." "No." She held the torch out to him. "Take it. Get on your belly and look along the platform toward the wall." He looked at her. He got down. She watched his shoulders go still. "There's — nothing coming back," he said. "Twenty people walk two hundred feet along a dead-end platform and then stop existing." Quinn took the torch back. "Now. About that staircase." She crossed to the body and stood at Ashcombe's feet. "Tell me what you see on his shoes." Pike came round, careful now. "They're clean." "Oxford brogues, leather soles, and they're clean. He came down thirty-nine steps of soot and there isn't a mark on the welts." She lifted the hem of the overcoat with the barrel of her pen. "But look at the back of the coat. Look at the heels of his trousers." Grey. Two long parallel smears of it, running from ankle to knee, and above them the coat was rucked up toward his shoulders like a shirt pulled the wrong way over a child's head. "He was dragged," Pike said. "On his back, feet first, from somewhere out there." She nodded down the platform. "Toward the stairs. Not far. Whoever was doing the dragging gave up at the mouth of the stairwell, which is where a sensible person would give up, because the alternative is carrying eighty kilos up a spiral in the dark. And the head wound —" She knelt and angled the light. "Depressed fracture, right parietal. Curved edge. Something with a rim struck him once while he was upright and facing whoever swung it. Nobody gets that shape falling on a step." "Then why drag him to the stairs at all?" "Because they wanted us to write what you wrote in your notebook twenty minutes ago." Quinn stayed down. Her torch had caught something in the curled hand, a wink of green-gold under the fingers. "Glove." Pike passed her one. She worked the fingers open. Cold, and stiffening, and they gave up their contents in pieces: a small brass compass, the casing furred with verdigris, its face crowded with tiny etched figures — spirals, eyes, a ring of marks that were not letters in any alphabet she'd been made to learn. The needle sat hard over. It ignored her. It ignored the tunnel, the rails, magnetic north, and pointed at the cream-and-oxblood wall with the tea advert on it. Quinn turned the compass ninety degrees in her palm. The needle swung and held. She turned it again. Held again. "Battery," Pike offered. "It's a compass." "Then the rails. All that iron." "The rails are behind me and it doesn't care." She stood, and the needle stayed with the wall like a dog watching a door. Footsteps rang on the spiral, quick and light, and Quinn had her torch on the stairwell before the second step landed. "Metropolitan Police. Stop where you are and come down slowly." The woman who came down was small and red-haired and wearing entirely the wrong shoes, and she had a leather satchel clamped under one arm with the strap wrapped twice around her fist. Round glasses threw the torchlight back. She stopped four steps up, which put her eyes level with Quinn's. "I called it in," she said. "About the lights. I'm the member of the public." "Name." "Eva Kowalski. I work at the British Museum, restricted archives." She tucked a curl behind her left ear. "I research Victorian tunnel systems. There's a permit, I can—" "At four in the morning." "The permit doesn't specify hours." Quinn came up two steps. "You rang from the street. Then you went home. Then you came back, past two officers and a cordon, in a hurry, carrying that." She looked at the satchel. "What's in it?" "Books." "What's in your left hand?" Eva's fist stayed shut. Behind Quinn, in her glove, the brass needle swung off the wall and hunted across the compass face and settled on the stairs, on the woman, on whatever she was gripping hard enough to whiten her knuckles. Quinn watched it move. She looked at the needle, and at the fist, and at the twenty sets of footprints walking into a wall, and eighteen years of decorated service turned over in her chest like a key finding, at last, the wrong lock. "Open your hand," she said. Eva opened it. A flat disc of yellowed bone lay on her palm, drilled through, warm enough that Quinn could see the sheen of sweat around it. "He had one too," Quinn said. "Didn't he. And somebody took it off him."
