The stairwell smelled of rust and standing water, and Quinn had counted forty-seven steps before the torchlight caught the bottom of it. The old Tube station had been sealed since the seventies — she'd checked the records on the drive over, because checking records was the kind of thing that kept her hands from shaking. Camden Borough Council had it listed as a structural hazard. No power, no maintenance, no reason for anyone living to be down here. And yet there were nine officers, a forensics tent, and a body. "Watch your footing, Detective." A young constable steadied a portable lamp as she came off the last step. The platform opened out before her, tiled in cream and oxblood, the curve of the ceiling vanishing into a dark that the lamps couldn't fully push back. The tracks below the platform edge had long since been pulled up, leaving a trench of gravel and black silt. "Who found him?" "Urban explorers. Couple of kids with a camera. They're upstairs, shaken up." The constable hesitated. "DI Reyes is already with the body, ma'am." Of course he was. Quinn adjusted the worn leather strap of the watch on her wrist — an old habit, a way of marking that she had arrived, that the clock had started — and walked the length of the platform with the unhurried, deliberate stride that eighteen years had taught her. You learned more in the first thirty seconds at a scene than in the next thirty minutes, but only if you slowed down enough to let the scene speak. This one was already saying something she didn't like. The dust. That was the first wrong thing. A station sealed for fifty years should be carpeted in it, undisturbed, the kind of grey felt that took your footprints like fresh snow. But the platform had been swept. Not perfectly — there were drifts in the corners, against the cracked tile skirting — but the central walkway was clean. Recently clean. She crouched and ran two fingers along the ground. They came away grey but not filthy. Someone had used this place, and used it often enough to keep a path clear. "There she is." DI Marcus Reyes straightened from beside the forensics tent, peeling off a blue glove. He was good-looking in a tired way, the sort of detective who closed cases by being likeable in interview rooms. "Wasn't sure they'd pull you in on this one. Bit out of the way." "They pulled me in because it's out of the way." She stood. "What have we got?" "Male, late fifties, no ID. COD looks like blunt force trauma to the back of the skull." Reyes pulled the tent flap aside. "Story tells itself, honestly. Vagrant, or one of these explorer types, gets down here, slips on the platform edge in the dark, cracks his head on the way down into the trench. We've got the impact point on the concrete lip, blood and hair, the lot. Tragic, but it's an accident waiting to happen in a place like this." Quinn stepped past him and looked at the body. The man lay on his back in the gravel trench, one arm flung wide, the other folded across his chest in a way that no falling body folded itself. His face was lean, grey-stubbled, the eyes half-lidded. He wore a long oilcloth coat, good boots, a knitted scarf — not the layers of a rough sleeper, but the deliberate dress of someone who'd chosen to come somewhere cold and wanted to be ready for it. "Slipped," she said. "Off the edge, yeah. Backward." "He's facing the platform." She gestured. "If he slipped off the edge backward, he falls away from it. His head should be toward the trench wall, feet toward the platform. He's the other way around. His head's pointing back at the concrete lip you've got blood on." Reyes frowned, looked, recovered. "So he turned as he fell. People windmill." "Maybe." She crouched at the trench's edge, careful not to disturb the gravel, and studied the dark crust on the concrete lip — the impact point. The blood there was a smear, a contact mark, a few strands of hair caught in it. But the body was nearly a metre away. "If he hit his head here and fell there, where's the spatter? A blunt-force wound to the skull bleeds. It bleeds a lot, and it bleeds where the blow lands and where the body goes down. I've got a smear on the concrete and a pool under his head, and nothing in between." "He could have crawled." "With his skull caved in?" She glanced up at him. "And he tidied his own arm across his chest after?" Reyes had the grace to fall quiet. Quinn took the small Maglite from her coat pocket and played it slowly across the trench floor. Gravel, silt, the rusted bolt-holes where the rails had been lifted. And there — pressed into the silt beside the body, half-filled by seepage but unmistakable — the prints. Not the cleated soles of police boots, not the dead man's heavy treads. Bare feet. Long, narrow, the toes too far apart, the heel oddly slight. Several sets of them, coming from the dark mouth of the tunnel and returning to it. A cold weight settled in her stomach, familiar and unwelcome. She had seen prints like that once before, on a riverbank in the rain, three years ago, the night DS Morris stopped answering his radio. She had told herself then that the mud had distorted them. She had told herself a great many things since. "Marcus," she said evenly. "Did your forensic team log these?" He came to the edge, looked down, and she watched his eyes pass over the bare prints without snagging on them at all. "Log what?" "The footprints." "His, you mean." He pointed at the dead man's boots. "Yeah, those are flagged." She looked at him for a long moment. He wasn't lying. That was the thing about Reyes — she'd worked beside him for years, and he didn't have the talent for it. He genuinely could not see the bare prints in the silt, the same way he could not see the swept walkway as anything but ordinary, the same way the whole scene had arranged itself into a tidy accident in his mind and refused to come apart. But she could see them. She always had. That was the curse Morris had died trying to spare her from understanding. Quinn rose slowly, brushing the grey dust from her knees, and turned her attention to the dead man's folded hand. Something glinted there, half-hidden under the cuff of the oilcloth coat. She crouched again and, with a gloved finger, eased the fabric back. A small brass compass lay against his palm, its casing green with verdigris, its face etched with markings she didn't recognise — angular, deliberate, almost like writing. The needle was not pointing north. It was pointing at the black mouth of the tunnel, trembling, as though something down there was pulling it. "That's not standard issue," she said quietly, more to herself than to Reyes. Behind her, Reyes was already saying something about wrapping up, about the coroner's van, about getting out of this dump before the air gave them all something. His voice had the flat, soothing quality of a man eager to be told the story was over. Quinn stayed where she was, looking at the needle, at the bare prints leading into the dark, and felt the old ground shift beneath her certainties. The evidence didn't add up. Which meant she wasn't looking at all of it yet. She slipped her phone from her pocket and, while Reyes's back was turned, photographed the compass, the prints, the impossible angle of the body. Then she stood and faced the tunnel, and the cold that came out of it had nothing to do with the depth. "Get the kids' statements properly," she told Reyes. "Word for word. And I want this station kept sealed. No one comes down here without my say-so." "Quinn, it's an accident—" "Then it'll survive a closer look." She gave the dark one last glance. There was a name forming at the edge of her mind, a name she'd been avoiding for three years, a young woman with an Oxford degree and a satchel full of books who would know exactly what the markings on that compass meant. She would have to make a call she'd sworn she never would.
