The minicab had dropped him at the lights on Camden High Street, and now Tomás Herrera was running, and Quinn was running, and the rain came down on both of them without preference. She'd watched him leave the Raven's Nest at half past eleven, the green neon of the sign bleeding across the wet pavement of Brewer Street, his black bag in hand, collar up against the weather. Three weeks she'd had the Nest under her eye. Three weeks of logging Silas's crowd in and out of that bar, and Herrera was the softest target of the lot — Tomás Herrera, twenty-nine, born in Seville, struck off the medical register for administering treatments nobody would put a name to in the paperwork. The clique's patch-man. She'd followed his cab north, meaning only to see where he slept. Then he'd made her tail somewhere past Mornington Crescent, bailed out at a red light, and bolted. "Herrera!" she shouted. "Police. I only want a word." He looked back once. Rain had flattened his dark curls to his forehead, and the little gold medallion at his throat jumped as he ran — Saint Christopher, patron of travellers. He was about to need him. "Turn back, Detective!" he called over his shoulder. "Not down here. Please." The please chilled her more than any threat would have. He cut left off the High Street, into the shuttered day-market, and Quinn went after him, shoes slipping on the wet paint of a crossing, her coat heavy with water. Tarpaulins cracked like sails in the wind off the canal. Herrera vaulted a chain strung across an alley mouth, and as his sleeve rode up she caught the pale line of the scar along his left forearm — the one in his file photograph, the knife wound. Confirmation, if she'd needed it. He ran like a man with somewhere to be. Not panic. Purpose. That frightened her more than panic would have. The alley narrowed. Above them, through a tear in the cloud, the moon slid out — a day shy of full — and slid back again. At the alley's end stood a green iron gate Quinn had driven past a hundred times and never once seen open. Chained, always chained. Tonight it stood ajar, and beyond it a tiled stairwell breathed cold air up into the night, and a peeling sign said NO ENTRY in letters older than her career. Herrera ducked through. Something fell from his fist and clicked across the threshold — small, white. Quinn's hand closed on it without consulting her: eighteen years of evidence habit. A knucklebone, carved with a mark she didn't know. Warm, though the night was cold. She pocketed it and went down. A dead escalator descended like a spine into the earth. The tiles were the colour of old teeth. On the wall, a roundel had been painted over in black, the station's name erased, and Quinn — who had grown up on this city's geography the way other people grew up on scripture — could not have said what station this was, or that it had ever existed. Behind her the rain's voice thinned and died. Below, other voices rose. Glass clinking. A fiddle playing in a time signature her feet couldn't find. And light — lamplight, by the way it breathed. Her earpiece crackled once and went silent. At the bottom of the escalator stood a man shaped like a door. Tall — Quinn was five-nine in her socks and used to looking level at the world, and he made her look up. His gloved hand was extended, palm up. Ahead of her, Herrera slapped something into that palm and was waved through, vanishing into the light and the crowd beyond. Quinn reached the warden. The hand did not move. "Token," he said. His eyes caught the lamplight and gave it back twice, like a dog's. She showed him her warrant card. He looked at it the way she might look at a bus ticket in Barcelona — an object whose entire category had failed to arrive. "Token." This was the first door, and she knew it. Behind her: the stairs, the rain, the rational city, a phone call, a report typed in fluorescent light. Ahead: whatever this was. Her hand went into her pocket and found the knucklebone — still warm, absurdly warm — and she laid it in his palm before she'd fully decided to. He turned it over. Nodded. "The market keeps the moon's calendar," he said. "Moon comes full day after tomorrow. We fold." His gaze dropped, briefly, to the cuffs on her belt. "Mind the rules." "What rules?" He smiled, and she wished he hadn't. "You'll learn them," he said. "Or you'll keep." Then she was through, and the market opened around her. It had been a platform once. The tracks were boarded over into a floor, and the tunnel mouths at either end were hung with curtains of chain that swayed though no wind blew. Stalls filled the alcoves where passengers had waited out a different century, lit by lanterns on sagging cable. Quinn's trained eye did what it always did — catalogued, assessed — and then, item by item, began to fail. Jars in which things turned slowly toward her as she passed. A man selling single gloves, each one flexing gently, as if remembering a hand. Vials of gold liquid that a woman weighed on a brass scale, weeping silver tears into a bottle as she worked. A book with a clasp like a mouth. The smells came in layers: wet stone, incense, copper, something sweetly rotten underneath. Stagecraft, her mind offered. Projection. Something in the incense. She held on to that the way she'd hold a rail on ice. Her phone showed no service — normal, underground, she told herself — but the clock on the screen read 00:00 and would not change. The watch on her left wrist, its leather strap gone soft with years, ticked on indifferently. Mechanical. Nothing in it to be hexed, she thought, and was disturbed to catch herself thinking it. She was forty-one years old, eighteen of them in the Job, and she had never in her life been this alone in her own city. No comms. No backup. No authority that meant anything here. Her warrant card was a bus ticket in Barcelona. She moved along the platform, scanning for a black bag, a gold medallion, olive skin, a scarred forearm — and stopped. A curio stall. A brass dish. In it, a careless heap of carved knucklebones, identical to the one she'd handed over at the door. Small change, here. Currency. Item fourteen, said a voice in her head, in the flat grammar of an evidence log. One carved bone object, origin undetermined. Morris. Three years gone. A stairwell in Whitechapel, a body without a mark on it, a pathologist's report written in the passive voice of the baffled. And closed in Morris's fist, a piece of carved bone that two specialists had failed to identify, bearing a mark no reference book could place. She had seen that mark in her dreams more often than she'd ever admitted to anyone, including the department counsellor. Here it was. Here it was small change. Her partner had died with this place in his hand, and nobody had known. Whatever the clique was into — whatever Herrera was into — it had touched Morris. The ground of the case, the ground of the last three years, shifted under her like a deck. Then, at the far end of the platform: a flash of gold. Herrera, at a curtained arch in the tunnel's mouth, talking fast and low to someone inside it. He glanced back — she was sure he saw her, sure his face changed — and then he was through the chains and gone, the curtain swaying in his wake. Quinn stood very still in the lamplight and ran the calculus. Withdraw. Climb. Call it in. Return at dawn with a team — and find what? A bricked-up stairwell. A painted-out roundel. A market folded with the moon, gone to some other dark, taking Herrera and every answer with it. Or go in. Alone, unarmed but for cuffs and a voice that used to command rooms, into territory whose rules she didn't know, whose warden had smiled at her like a man watching a fish consider the hook. Every instinct eighteen years had honed said withdraw. Everything that had happened to Morris said go. She set her jaw. Checked the watch — 00:11, the second hand steady, one sane thing in a place that had misplaced its sanity. Above her there was rain falling on a city she understood, and a desk, and a file with Morris's name on it that she had never once closed. Quinn stepped off the edge of the lamplight and went down the platform toward the chained dark, and the market, noticing her at last, made room.
