The ticket hall stank of wet copper and something older, something Quinn couldn't name but recognised in the base of her skull. She ducked under the tape strung across the boarded entrance to the old Camden Tube station and descended, torch beam skimming tile that hadn't seen polish since the Blitz. "Ma'am." DC Rahimi met her halfway down, clipboard clutched to his chest like a shield. "Body's on the eastbound platform. Forensics is already down." "Who called it in?" "Urban explorer. Kid climbed in through the ventilation shaft on Kentish Town Road." He swallowed. "He's upstairs with a paramedic. Won't stop shaking." Quinn thumbed her torch off as they cleared the last flight. The platform had its own light, portable halogens set up in a crooked semi-circle, and the glare turned every shadow into an accusation. The smell thickened — iron, yes, but also a sweetness underneath, like overripe fruit left in a drawer. DI Callum Reeves stood at the edge of the cordon, notebook open, pen tapping his teeth. He turned at her approach and offered the half-smile he reserved for ex-colleagues he still liked. "Harlow. Thought you were off rotation this week." "I was. Chief Super rang." She stepped past him. "Said the scene was, and I quote, 'unusual.'" "He's got a gift for understatement." The body lay on its back between the platform edge and the tiled wall. Male, mid-thirties, charcoal overcoat, one brown brogue missing. His eyes were open and very clear. No blood pool. No wound visible at this angle. Quinn crouched, knees complaining, and tilted her head until the halogen found the side of his throat. Nothing. Skin unmarked. "Cause of death?" "Forensics is calling it cardiac, pending post-mortem." Reeves crouched beside her. "Probably got spooked down here. Dark place. Dodgy heart. Falls, dies. Kid finds him two days later." "Two days?" "Lividity suggests it." Quinn didn't answer. She was looking at the floor. The platform was filthy — decades of dust, rat droppings, the powdery residue of fallen tile grout. But around the body, in a rough oval perhaps three metres across, the floor was clean. Not wiped clean. Scoured. As if something had drawn the dust up and away, leaving the concrete beneath exposed and pale. "You see this?" Reeves frowned. "See what?" "The dust." "What about it?" "There isn't any." She traced the oval with her torch. "Here. And here. Stops dead at this line." "Draught, maybe. Trains haven't run through here in seventy years but the tunnels still breathe." "A draught would smear it. This is a hard edge." Reeves stood, knees popping. "Harlow. The man had a heart attack in a derelict station. The interesting bit is how he got in, not what the dust's doing." She heard him, and didn't. Her eye had caught something else. She leaned closer to the body, close enough that the sweet rot smell climbed into her sinuses, and she held her breath. His left hand was curled, palm up. Between the index and middle finger, almost hidden in the crease, sat a small dark fleck. She fished a glove from her pocket, pulled it on, and teased the thing free. A sliver of bone. Yellowed. The edge worked smooth, not snapped. A fragment of something that had been whole and deliberate. "What've you got?" "Bone chip." She held it to the light. Marks, tiny ones, too regular to be natural. "Engraved." Reeves took it from her, squinted. "Piece of jewellery. Tooth from an old necklace, maybe. Means nothing." "It means he was carrying something made of bone, and now he isn't." "Or the explorer kid pocketed the rest before we got here." "The kid's eighteen and covered in his own vomit. You think he stopped to harvest souvenirs?" Reeves gave her the look. The one that meant: don't make this one of yours. She ignored it. She stood, turned a slow circle, and let the platform arrange itself behind her eyes. The halogens. The oval of clean concrete. The body, not flung, not dragged — placed. Legs straight. Arms at his sides, apart from that one curled hand. His overcoat was open. His shirt was buttoned wrong, one hole off from the top, as if he'd dressed in the dark or in a hurry. "Reeves. Where's his shoe?" "What?" "He's missing the right brogue. Where is it?" Reeves scanned the platform. "Fell off in the struggle?" "You said there wasn't a struggle." "I said heart attack." "Right." She walked the oval's perimeter. "So where is it?" They looked. Forensics looked. Rahimi joined in, grateful for a task. The shoe was not on the platform, not on the tracks below, not in the stairwell, not in the ticket hall. A polished brown brogue, size ten, vanished. Quinn came back to the body. Her left wrist itched under the leather strap of her watch; she rubbed it without thinking. Eighteen years of service had taught her that the wrong things at a scene were rarely the loud things. It was always the small absence. A missing shoe. A clean circle of floor. A bone chip in a dead man's hand. She knelt again. Looked at his face. Clear eyes, mouth slightly open, an expression she'd seen before — not fear, not pain. Recognition. He had seen whoever, or whatever, had come for him, and he'd known it. Three years ago, Morris had worn that same expression in the last photograph Quinn ever took of him alive. She had not allowed herself to think of it since. She did not allow herself now, not fully, only enough to register the shape of the thought before she put it down. "Reeves." "Hm?" "When's the next full moon?" He stared at her. "You're joking." "Humour me." He pulled out his phone, thumbed at it, and frowned at the screen. "Tonight. Why?" Quinn looked down at the dead man, at the oval of swept concrete, at the bone chip now sealed in an evidence bag on her palm. "Because this station is about to have visitors," she said, "and I don't think any of them will be ours."
