The drainage tunnel beneath King's Cross smelled of rust and standing water, and Detective Harlow Quinn hated it before she'd descended six rungs of the maintenance ladder. Her torch beam cut through the dark and landed on the white tent the forensics team had erected against the curved brick wall. Generators hummed. Somewhere ahead, water dripped with the patience of centuries. "Watch the last rung," called a voice from below. "It's slick." She dropped the final two feet and steadied herself against the wall. DC Reyes waited at the bottom, clipboard tucked under one arm, a paper cup of coffee steaming in his hand. "Tell me why I'm forty feet underground at three in the morning," she said. "Body. Male, mid-thirties. Maintenance crew found him during a routine inspection." Reyes handed her the cup. She didn't drink it. "No ID yet. No phone. Pathologist's putting time of death between midnight and two." Quinn moved toward the tent. The brick here was old, Victorian, furred with damp moss. No graffiti. That registered before anything else. Every tunnel in this city wore the marks of someone who'd been there before — taggers, urban explorers, the desperate. This one was clean. "How'd he get down here?" she asked. "That's the thing." Reyes flipped a page on his clipboard. "Only access is the ladder you just came down, and the grate up top was locked. Padlock intact. Maintenance crew had to cut it." She crouched at the threshold of the tent and lifted the flap. The man lay on his back, arms at his sides, as though someone had arranged him. His face had gone the colour of tallow. No blood pooled beneath him, no obvious wound. His clothes were dry. That was the second thing that didn't fit. Quinn looked back over her shoulder at the water sheeting across the tunnel floor, at the mud Reyes had tracked, at her own footprints already filling. "His shoes," she said. "What about them?" "Clean. Dry. He walked through none of this." She pulled a glove from her jacket and snapped it over her fingers. "Help me roll him." They turned the body. Nothing on the back, no exit wound, no lividity where there should have been. A man dead two hours should have settled. The blood should have pooled to the lowest points of him. Instead his skin looked uniform, waxy, as if he'd been drained and posed. "Reyes. What's your read?" He shifted his weight. "Overdose, maybe. Brought down here by whoever he scored from, dumped to keep them clear of it. Tunnel like this, nobody finds him for months." "Through a locked grate." "They had a key. Lifted it, copied it. Half these maintenance contracts get subbed out to firms that hire anyone." He sounded like he believed it. He probably did. It was the answer that let everyone go home. "We find the dealer, we close it." Quinn said nothing. She set her torch on the ground, angled so it raked across the floor at a low slant, and she looked at what the light showed her. Footprints. Hers. Reyes's. The forensic team's, marked with little yellow tents. And around the body, a clean radius where no one had walked — except no one could have laid the man down without standing in that radius. The mud should have held the killer's prints. It held nothing. The dead man lay at the centre of an untouched circle, as if he'd dropped from the ceiling. She tilted her head back. The bricks arched overhead, unbroken, forty feet of solid Victorian engineering. No hatch. No seam. "Reyes, get me the time the grate was last inspected." He thumbed through his pages. "Six weeks ago. Logged and signed." "And the padlock that the crew cut. Where is it?" "Bagged. Why?" "Bring it." He fetched the evidence bag and passed it to her. She held it under the torch and turned the padlock over. The shackle had been sheared by bolt cutters, that much was honest. But the body of the lock — she looked at the keyhole. Around it, a faint discolouration ringed the brass, a bloom of green-grey corrosion that didn't belong on a lock six weeks in service. Verdigris. The same patina that crept across old copper left in damp places for years. Her stomach turned over, slow and cold. "Three years ago," she said, and stopped. "Boss?" She didn't answer him. She was thinking about DS Morris, about a basement off the Caledonian Road where she'd found him laid out like this — arms at his sides, skin gone to wax, in a room with one locked door and no footprints but her own coming in. She'd told herself for three years it had been a fugue, a trauma she'd misremembered. The official report read heart failure. She'd signed it because there was nothing else to write. "Reyes. Did anyone touch his hands?" "SOCO photographed them. Nobody's moved—" She was already crouching, lifting the dead man's right hand by the wrist. The fingers had curled, not in rigour but in a grasping shape, as though they'd closed around something in the last moment and held it. She pried the cold digits open one by one. In his palm sat a sliver of bone. Yellowed, worn smooth by handling, no longer than her thumb, drilled through one end as if it had hung from a cord. "What is that?" Reyes leaned over her shoulder. "Animal bone? Some occult thing?" "He came down here on purpose." Quinn's voice came out flat, certain, the doubt burned off it. "He wasn't dumped. He came through a door we can't see, and he was carrying the key to it." She held the bone token up to the light, watched the torch catch its polished surface. "Look at the floor again. There's no break-in because nobody broke in. The grate was never the way down." "That's not—" Reyes rubbed the back of his neck. "Boss, listen to yourself. There's a rational explanation. There's always a rational explanation." "I used to think so." She slipped the bone token into an evidence bag of her own, one she didn't log, and closed her fingers around it. The verdigris on the padlock, the dry shoes, the circle of clean mud, the curled hand. Eighteen years of decorated service had taught her to trust the evidence over the story. The evidence was screaming, and it wasn't saying anything Reyes wanted to hear. She stood, knees aching, and looked once more at the dead man's tallow face. "Bag everything. Photograph the floor, all of it, the clean circle especially. And I want the name of every firm subbed onto this tunnel's maintenance for the last three years." "You're going to chase the dealer angle?" "No." She pocketed the token and felt its small weight settle against her hip like a question she finally meant to answer. "I'm going to find out where this man was before he was here. And what he came down to buy."
