The rain came down like it had a grudge against Camden. Quinn had been standing in it for forty minutes outside the Raven's Nest, watching that green neon bleed across the wet pavement, and her coat had given up somewhere around minute fifteen. Water ran off the back of her collar and down between her shoulder blades. She didn't move. Then the side door opened and Tomás Herrera came out fast, hood up, and turned left instead of right. Left was wrong. Left was away from the Tube, away from the night bus, away from the flat in Kentish Town she'd already pulled the lease on. Left meant he had somewhere else to be. Quinn pushed off the wall. She stayed on the far side of the road for the first three hundred metres, keeping a van and then a skip between them, her boots finding the quiet parts of the pavement out of eighteen years of habit. Herrera moved like a man who'd been taught to look over his shoulder but hadn't been taught to do it well. He checked behind him at every second corner. Predictable. She timed her steps to his rhythm and let the rain cover the rest. At Kentish Town Road he stopped under the awning of a shuttered kebab shop and took something from his jacket. Small. Pale. He turned it over in his fingers like a man counting rosary beads, and the streetlight caught it — not plastic, not metal. Yellowish. Porous at the edges. Bone, Quinn thought, and something cold walked up her spine that had nothing to do with the weather. Three years ago they'd pulled Morris out of a stairwell in Deptford with his eyes open and no mark on him anywhere, and in his fist, so tight they'd had to break two fingers to get it out, a little disc of bone with a symbol scratched into it. She'd filed it. She'd asked questions. She'd been given a bereavement leave form and a number for the counselling service. Herrera pocketed the token and started walking again. Quinn crossed. She closed to thirty metres. Then twenty. Water sheeted off a broken gutter and she went through it without slowing, and maybe that was the mistake — the splash, the sound of a footfall that wasn't rain — because Herrera's head came round and this time he didn't just look. He saw her. For half a second neither of them moved. Under the hood his face was all planes and shadow, olive skin gone grey in the sodium light, and she watched the calculation happen behind his eyes. Then he ran. "Police!" Quinn shouted, and hated herself for it, because the word only ever made them faster. "Herrera! Stop —" He was quick. Paramedic quick, the kind of fitness that came from years of carrying dead weight up narrow stairs, and he knew the ground. He went off the pavement into a service alley behind the pound shops and Quinn went after him, shoulder clipping a wheelie bin, the lid clanging behind her like a starting gun. Puddles exploded under her feet. Her lungs began their protest at the second corner and she told them what she always told them, which was later. "You'll want to think about this," she called. Save the breath, some part of her said, but talking was pressure and pressure made men stupid. "There's nothing on you yet. Nothing that sticks. You stop now, you're a witness." His answer was a fire escape. He hit it at speed, hauled himself up two rungs, then dropped back down and cut right instead — a feint, and a good one; she'd already committed her weight towards the ladder and lost a full second recovering. Right took them out onto a stretch of hoarding where the council had been promising a development for six years. Plywood, graffiti, a gap where two boards had been prised apart and never fixed. Herrera went through it sideways without slowing. Quinn followed and came out into what used to be a station forecourt. She knew this place. Everyone knew this place. Disused since the fifties, sealed, condemned, and photographed by every urban explorer with a blog. The tiling above the boarded arch still said the old name in cream and oxblood, half of it lost behind a crust of moss. The rain drummed on corrugated iron and the whole yard smelled of rust and wet brick and something sweeter underneath, like sugar burning. Herrera had stopped at a maintenance door set into the arch. Not stopped to surrender. Stopped to open it. "Herrera." Quinn slowed to a walk. Twelve metres. Ten. Her hand went to her belt out of instinct and found her radio, her cuffs, her torch, and nothing else, because this was supposed to be a surveillance shift. "Tomás. Look at me." He looked. He was breathing hard, one hand flat against the door, and he was frightened — but not of her. That was the thing that landed wrong. He kept glancing past her, up, at the rooflines and the gaps in the hoarding, like the rain might be carrying something. "Go home, detective." His accent thickened when he was winded. "Please. Go home and write that you lost me." "Can't do that." "You don't know what this is." "Then tell me." "I am telling you." He pressed the pale disc against a plate beside the handle and Quinn heard something in the door move that no lock in her experience had ever sounded like — a long soft grinding, like teeth. "I'm telling you the only useful thing anyone will ever tell you. Go home." He went through. The door swung shut, and she got one glimpse of what was on the other side: not the black of a derelict stairwell but a warm crawling amber, like firelight, going down. Quinn reached the door in four strides and it was already sealed. No handle her side. She put her shoulder into it anyway, twice, and got nothing but a bruise. She stood in the rain with her palms flat on the wood and made herself think. Protocol was simple. Withdraw. Call it in. Request a unit, request a warrant, request a structural assessment for an unsecured Victorian station box, and by the time any of that arrived Herrera would be in Seville or worse, and whatever was down those stairs would be a rumour again, and DS Morris would stay filed under unexplained. She'd done it the right way once. She'd sat in that inquest room and watched a coroner write *misadventure* in a hand that never shook. The rain kept coming. Somewhere under her feet, faint through brick and clay, something was playing music — a thin reeded thing with too many notes in it. Quinn crouched and ran her fingers along the base of the door. Grit. A gap of maybe two centimetres. And wedged in the corner where the frame met the sill, catching the light, something small and pale. She worked it out with her fingernails. A bone token. Chipped along one edge, warm, which made no sense in weather like this, and scratched with a symbol she'd last seen prised from a dead man's fist. Quinn looked at it a long moment. Then she stood, wiped the rain out of her eyes, and pressed it to the plate. The door made its grinding sound. She turned her radio off before she went in — because a signal was a leash and a leash could be pulled — and then she stepped through onto the top of a staircase that smelled of tallow and cardamom, and the door shut behind her, and the amber light went down and down and down.
