Detective Quinn ducked under the police tape strung across the mouth of the old service tunnel, the beam of her torch catching motes of dust that hung motionless in the dead air. Camden Town station rattled somewhere above her, muffled through forty feet of London clay, but down here the silence had a texture to it, thick and expectant. "Careful of the third step," Sergeant Devlin called from below. "Someone's already gone arse over tit on it tonight." She took the stairs two at a time anyway, boots striking concrete slick with condensation. The disused platform opened up ahead, lit by a ring of portable floodlights that threw everything into a flat, clinical white. A body lay near the platform edge, half in shadow where the light couldn't quite reach. "Talk to me," Quinn said, crouching a few feet back from the corpse, close enough to read the scene, far enough not to disturb it. Devlin flipped open his notebook, though she suspected he'd already memorised whatever he'd written. "Male, mid-thirties. Found by a transport worker doing a structural check before the demolition crew moves in next month. No ID on him. No wallet, no phone, nothing." "Cause of death?" "That's the fun part." Devlin crouched beside her, close enough that she caught the mint on his breath, the kind coppers chewed to cover the smell of last night's pint. "Pathologist's initial read is exposure. Hypothermia, maybe. Dehydration." Quinn looked at him. "Down here," she said. "In June." "People do strange things when they're off their heads, Quinn. Squatters, junkies. He could've wandered down, got lost, panicked. Cold as a morgue in these old tunnels even in summer, you know that." She did know that. She also knew hypothermia didn't leave a man's skin the colour of old parchment, didn't shrink the flesh back from his fingernails like something had drawn the moisture out of him from the inside. She leaned closer, careful not to touch, and studied the dead man's face. His eyes were open, fixed on the curved ceiling above, and there was no fear in them. Just a kind of exhausted wonder, like he'd seen something worth the price of looking. "He's been dead less than six hours," she said. "Skin hasn't degraded enough for longer. But look at his hands." Devlin leaned in, obliging but unconvinced. "What am I looking at?" "The nails. Brittle, cracked, yellowed at the base. That takes months to develop, not hours. Same with the hair — see how dry it is, how it's thinning at the temples? That's not a man who wandered down here yesterday. That's a man who's been ageing for years, compressed into an afternoon." "Could be a pre-existing condition." "Could be." She didn't believe it, and she suspected Devlin didn't either, not really — she'd seen him hesitate before he offered his tidy little theory, seen the way his eyes kept sliding to the far end of the platform where the floodlights gave out and the tunnel curved into proper dark. "What's down there?" "Nothing. Dead end. Bricked up, according to the transport authority's schematics." "Then why do you keep looking at it?" Devlin didn't answer straight away. He rubbed the back of his neck, a habit she recognised from three years of working murders with him, the same tell he had whenever a scene didn't sit right and he wanted it to be simple anyway. "There's a draught coming from that direction," he said finally. "Cold air. Shouldn't be, if it's bricked up solid." Quinn stood, joints protesting the crouch, and walked the platform's edge with her torch angled low, sweeping the ground rather than the walls. Fifteen feet from the body, the dust told its own story — scuffed in a wide, dragging arc, as if something heavy had been pulled, not carried. No footprints leading to it. No footprints leading away, save the dead man's own, which stopped abruptly six feet from where he lay, like he'd simply stood still and let whatever happened, happen. "No forced entry," she said. "No sign of a struggle. He didn't fight anyone off, and nobody dragged him down here against his will. He came on his own two feet and stayed put." "Meeting someone?" "Or waiting for someone." She crouched again at the edge of the scuff marks, careful to keep her shadow off them. A faint smell rose from the concrete here, sweetish and metallic, not blood, not anything she'd catalogued in eighteen years of crime scenes. "You smell that?" Devlin sniffed, wrinkled his nose. "Sewage, probably. This close to the old drainage line." It wasn't sewage. Quinn had smelled sewage more times than she cared to count, and this was something else entirely — cold and clean underneath the sweetness, like frost on metal. She'd smelled it once before, three years ago, in a stairwell in Whitechapel, the night she'd lost Morris and gained a scar along her ribs she'd never adequately explained in any incident report. She didn't say any of that to Devlin. She stood instead, brushing grit from her knees, and looked again at the bricked-up end of the tunnel, at the draught that shouldn't exist and the dust that told a story with no beginning. "I want SOCO to check behind that brickwork," she said. "Properly. Not a knock-and-listen, an actual structural survey." "That'll take days. The demolition crew's not going to wait on a hunch, Quinn." "It's not a hunch." She crouched one final time by the body, studying the set of his jaw, the strange, hollowed wonder in his open eyes. "A man doesn't walk into a dead-end tunnel and stand still while his body ages thirty years in an afternoon. Something met him down here. Something came through that wall and left the way it came, and I want to know what." Devlin closed his notebook, slower now, some of the mint-fresh confidence gone out of his voice. "And if there's nothing behind that wall?" Quinn looked at the draught stirring the dust at her feet, cold air breathing out of solid brick, and didn't answer him at all.
