The Northern line platform had been dead for decades, and the tiles still wore the ghosts of adverts for a brand of cigarettes that no longer existed. Quinn ducked under the blue-and-white tape at the bottom of the stairwell and felt the air change. It was colder down here than the November night above, and it carried a faint sweetness, like a church after the candles had been snuffed. "Ma'am." DC Owen Marsh waited by a support pillar, his hi-vis jacket glowing under the work lamps. He had the flushed cheeks of a man who had been awake too long and had decided to enjoy it. "Glad you came. Didn't think you'd want to bother with a tunnel job." "Tell me why it's a tunnel job." Marsh gestured with his notebook toward the middle of the platform. "Maintenance crew found him at half five. Bloke's fallen from the walkway above, looks like. Access hatch was open. Landed badly." Quinn stepped closer. The body lay on its side at the edge of the yellow safety line, one arm folded beneath the chest, the other stretched toward the tracks as though reaching for something that had rolled away. Late fifties, grey overcoat, good leather shoes scuffed at the toes. A tweed flat cap sat upside down a yard from his head, its lining turned out. She crouched beside him and did not touch anything. The left wrist was bare. A pale band of skin showed where a watch had been for years, and the skin around it had not yet caught up with the loss. "Who is he?" "No wallet. No ID. We're running prints." Marsh shifted his weight. "Honestly, ma'am, I think he was pissed and wandered up the old service stairs. Happens more than you'd credit. Nobody's been down here in ages." Quinn let the silence sit. Marsh, to his credit, filled it with something useful after a moment. "There's a bit of a smell," he offered. "Cordite, maybe? Or fireworks." "Fireworks would be a fine thing to have on a platform with no lights," Quinn said. "Show me the walkway." They climbed the rusted stairs to the gantry that ran above the tracks. Here the dust lay thick and undisturbed except for a single trail of footprints, heavy-soled and widely spaced, coming from the hatch and ending at the rail. Quinn knelt and studied them without rising. Two prints, then a long gap, then two more. Whoever had made them had not been walking so much as stepping across something. "Lads from forensics will want these photographed before someone treads on them," she said. "Already on it." Marsh crouched too, his torch beam bobbing. "See? He's come up here, slipped, gone over. Simple." "Simple," Quinn repeated. She rose and pointed at the rail. "Look at the paint." The rail was painted a flaking green. Along the top bar, where a hand would grip, the paint had been scraped away in a neat half-circle. Beneath it the metal shone dull and dark, almost black, as though it had been rubbed with ash. "Rust," Marsh said. "Friction." "Rust doesn't write a pattern." Quinn leaned close and angled her head. Along the scraped arc ran a line of tiny indentations, evenly spaced, each one no bigger than a grain of rice. "Those are not from a fall. Something was pressed against this rail on purpose. Repeatedly." Marsh frowned at it. "Could be anything. Keys. Coins." "Could be." She walked back toward the hatch. The walkway boards were sticky underfoot in a way that had nothing to do with the damp. She stopped, crouched, and touched one fingertip to the surface. Nothing came away on her skin. Not blood, not oil. Just a faint warmth that should not have been there in a space this cold. "Owen. Did the maintenance crew touch the hatch?" "Dunno. Probably. Why?" "Because it's been shut and reopened by someone who wanted it to look like it had been forced from below." She nodded at the bolt. The metal was bright where something had struck it, but the scratches ran the wrong way. "If a man climbed up and fell, the hatch would be pushed outward. These marks show it was dragged open from the inside." Marsh opened his mouth, then closed it. Quinn went back down the stairs, one hand on the rail she had already decided not to trust. At the bottom she turned slowly on the platform, letting her eyes travel the length of the tiles. Near the pillar where Marsh had been standing she noticed a patch of floor that was cleaner than the rest. The dust had been brushed in a broad circle, roughly the width of a man's outstretched arms, and at its centre lay a small ring of grey powder that had been drawn into a pattern and then smudged by the heel of a shoe. "What's that?" Marsh asked, following her gaze. "Ash, I'd say. Bone ash, if I'm honest, though I hope I'm wrong." Quinn didn't kneel this time. "Somebody stood in that circle and waited. Then they walked up to the hatch and the dead man walked up to meet them." "Ma'am, with respect, that's a bit of a leap." "Then leap with me for one minute." She pointed at the body. "Look at the coat. Buttons are done up wrong. Top one into the second hole. A man who's been drinking all evening doesn't button his coat like a soldier on parade, and a man who's climbing a gantry doesn't keep his cap in his hand. The cap was taken off him. Then the watch was taken off him too, and I'd guess it wasn't a thief who did it, because a thief would have left the shoes." Marsh looked at the body, then at the cap, then back at her. His mouth worked silently. "And there's no blood on the tiles," Quinn went on. "He landed on his side, and that's a fall that should have put blood on the concrete. There's a dark stain on his collar, and his hands are clean. Someone washed them, or they were never in the fight at all." "Could be the cold." "Could be." Quinn turned her wrist over and studied the dial of her own watch, a battered leather strap that had outlasted two partners' worth of birthday presents and one long-dead marriage. The second hand moved with steady precision. The stranger's watch, wherever it was now, had surely stopped at the same minute the man hit the floor. "The thing I can't explain is why the tunnel is so warm at the rail and so cold everywhere else." Marsh's torch wavered across the tiles. "What do we do, then?" "We photograph every mark on that rail, every print on that gantry, and the ash in that circle, before anyone sweeps it. We get a sample from the scrape." Quinn turned toward the stairs, then paused. "And you find out who has been coming down here at night with a bone token in their pocket." "A what?" "Nothing yet," she said, and started back up toward the street.
