The rain came down like it had a grudge. It rattled on the iron grates along Camden High Street, slicked the pavement to a black mirror, and drummed against the shoulders of Detective Harlow Quinn's coat as she ran. Herrera had twenty meters on her. He moved like someone who had been chased before — head down, elbows tight, no wasted glances behind. A runner's economy. She'd clocked the scar on his forearm back at the Raven's Nest, when he'd reached across the bar to palm a folded envelope from a man she had been watching for six weeks. The envelope had gone into his jacket. He had looked up, and for one clean instant his warm brown eyes had found hers in the mirror behind the bottles, and he had known. Then he had bolted, and the green neon of Silas' sign had smeared past her as she followed. That had been eight blocks ago. Quinn kept her breathing metered, three strides in, three strides out, the way the service had taught her when she was twenty-three and still thought she understood the world. Her radio was clipped to the inside of her lapel. She didn't call it in. Not yet. The moment she put Herrera's name over the air, half the Met would want to know why she was two boroughs outside her patch, chasing a man whose file officially didn't exist. He cut left down Kentish Town Road, and she cut with him. A cyclist swerved, shouted. A bus heaved past, sending a cold sheet of gutter water over her knees. She barely felt it. Her eyes were on the back of Herrera's head — short curly hair plastered flat, the gleam of something on a chain around his neck swinging free of his shirt as he ran. A medallion. Saint Christopher. Patron saint of travelers, of people running for their lives. He made a mistake at the crossing by Inverness Street. He glanced back. That was what she needed. The glance told her he was tired, that the envelope mattered enough to keep, that he hadn't ditched it in any doorway yet. She closed three meters in the time it took him to turn his head. "Herrera!" she shouted. "Metropolitan Police! On the ground!" He didn't go down. He ducked between two parked vans and vanished. Quinn swore and followed. The gap between the vans stank of diesel and piss. Beyond it she found a narrow service road, a skip piled high with sodden cardboard, and — there — a wrought-iron railing hanging loose from its post, peeled back like a page. Behind the railing, a flight of concrete steps fell down into the dark. She knew this stretch of Camden the way any copper with eighteen years' service knew their city. There was no Tube station here. There hadn't been one in sixty years. The line had been closed since the war. She drew her torch. She drew her sidearm, a small comfort she was not officially supposed to be carrying. At the top of the steps she paused, just long enough to hear — beneath the hiss of the rain — the slap of his shoes on stone, dropping away and away. Her watch ticked against her wrist: the old leather strap she hadn't replaced since DS Morris had given it to her on her promotion. Morris, who had chased a man down a staircase not unlike this one, three years and four months ago, and never come back up. She went down. The stairs took two turns and ended in a tiled vestibule gone yellow with age. Posters hung from the walls in rags: Ovaltine, war bonds, a girl smiling over a cup of tea from 1943. The air was warm. That was the first thing that wasn't right. You went underground in London, you got the cold of the tunnels, the ghost-draft of trains in other lines pulling the air through. This was warm, and it smelled of woodsmoke, of cardamom, of something metallic she couldn't place. Ahead, an archway. Inside the arch, a curtain of what looked like black beads — except as the torchlight brushed them they shifted and clicked, and she realized they were small bones, polished, strung on wire. Finger bones. Something smaller. Birds, maybe. She did not want to know. On the floor at her feet, a Saint Christopher medallion lay in a puddle of rain that had run down from her coat. The chain was snapped. He'd dropped it. Or left it. From beyond the curtain came the low churn of voices. Dozens of voices. A market's murmur, the soft bargain-noise of people who did not want to be heard. A woman laughed, high and bright. Something — she could not tell what — barked once, and was hushed. Quinn's hand tightened on the grip of her pistol. She crouched, picked up the medallion with two gloved fingers, and turned it in the torchlight. Warm to the touch. Warmer than it should have been after lying in cold water. She thought of Morris. She thought of the report she had written and rewritten and never filed, the one that used words like inconsistent and anomalous because she could not bring herself to write the words she meant. She thought of the way the duty sergeant had looked at her, afterward, and how he had stopped looking at her at all. She thought: this is the kind of door he went through. The sensible thing was to back up the stairs, call it in, cordon the entrance, wait for tactical. The sensible thing was not to push through a bone curtain into a warm underground no one had told her existed. The sensible thing was what had kept her alive for eighteen years. Herrera had the envelope. Herrera had answers. Herrera was, right now, thirty seconds ahead of her and bleeding velocity into a crowd. Quinn pocketed the medallion. She clicked her torch off — whatever light was on the other side of the curtain would be enough, and she did not want to announce herself — and she let her eyes adjust to the thin red glow seeping through the bones. She breathed in, three counts. Out, three counts. Then Detective Harlow Quinn pushed aside the curtain of small bones, and stepped into the Veil Market, and the door of her old, reasonable life closed quietly behind her.
