Rain ran down the green glass of the Raven's Nest sign and fractured into needles on the street. Inside, the air smelled of malt, wet wool, and the iron tang old photographs had when damp crept through the walls. Detective Harlow Quinn sat with her back to the maps, watching the bookshelf by the bar. The volumes looked solid, encyclopaedias, shipping logs, atlases with cracked spines. They were a wall. The wall had moved twice in the past hour. Tomás Herrera had gone through it once. He came out with a black medical bag that had not been on his hip when he entered. Quinn's left thumb brushed the worn leather of her watch. Eighteen years. Enough years to learn that a door in a bar meant a second business. He noticed her at the table. His warm brown eyes narrowed, and his hand closed around the bag's strap. "You were in that room." The old barman polished a glass and did not look up. The photographs on the wall, faces from another century, a river frozen before the embankment was built, held their stillness. Herrera turned for the side passage. Quinn moved before the chair could complain. Her knee caught the table edge; the glass of water tipped and spilled across maps. Herrera had already hit the door with his shoulder. The hinges shrieked. She was three steps behind when he burst into the night. The alley was narrow and slick. A green bin stood against the brickwork, its lid open. Herrera went over it without slowing. His boots splashed through a shallow river of rainwater. A medallion bounced at his throat. St Christopher. Patron of travellers, useless at a run. Quinn took the bin's metal lid and dropped onto it. Her right calf pulled, a hot wire under skin, but her balance held. She came out into Charing Cross Road with the door at her back, the bar's sign bleeding neon onto the wet tarmac. Herrera was fifty yards ahead, heading west with the medical bag swinging. His curly hair was dark and flat. The scar on his forearm showed white when his cuff rode up. She did not shout. Shouts made people faster. She stepped into the flow of the street, counting the distance. Nine. Ten. Twelve. Rain needled her scalp. The closely cropped hair had grown since Morris died; it used to be nearly white at the temples, now it had grey threading through black. Eighteen years and a dead partner had left few places for vanity. Her jaw tightened, sharp as a blade in the light. Herrera turned into a side street lined with shuttered shops. A taxi driver swerved as he appeared from the kerb. The tyres hissed. The taxi horn bled into the rain. Herrera kept going, cutting across a forecourt where a black cab stood with its meter blinking, empty. He pulled a set of keys from his pocket and jabbed the fob. The cab's doors unlocked. Quinn reached the forecourt edge as the cab shot forward. Something slid from the medical bag and hit the wet tarmac. Herrera did not look back. She crouched. The object was small, pale, no bigger than a coin, carved with a mark that had been worn smooth by a thumb. Bone. Her unmarked Vauxhall sat two streets away, its roof black with rain. She got in, started the engine, and pulled into the lane the taxi had taken. Camden's arches opened like wet mouths. The taxi stopped by a closed station entrance with the roundel cracked and a boarded notice across the stairs. Quinn cut her headlights and pulled opposite. She watched Herrera pay through the window, then get out. He had the medical bag. He looked back once. She ducked beneath the dashboard. When she rose, he was gone down the stairs. Rain hammered the windscreen. The wipers made no sense to the street. No sign on the stairs, no platform notice, no guard. Only a metal door set into the brickwork, half-hidden behind a shuttered newsagent's. The door was new enough for the screws to be bright. A woman sat inside the entrance on a folding chair, visible through a gap. Her hands rested on a wooden board. On the board lay more tokens, strings of them, each cut with a different mark. Quinn approached. The woman looked up. Her eyes were brown and tired. "Market's for clients." The voice was flat, not hostile, not welcoming. Quinn held up the bone. "Found this." The woman did not move. "Found things get spent here." "Herrera went through." "Then he belongs inside." "He's carrying evidence." "The market carries what people need." The woman nodded at the token. "Hand it over." Quinn tightened her fingers. The rain ran into the gutter and blacked out the edge of the stairs. Through the open door's lower seam, she smelled damp, candles, something metallic, and another smell like a hospital corridor cleaned too hard. She looked down. A single light burned at the bottom. The walls were tiled with old cream squares and newer black paint. A discarded poster showed a Tube map with Camden Town crossed out. The platform beyond had been walled in long before London had admitted it was dead. "If I go through, what happens to the man with the medical bag?" "He answers for the room he enters." "He answers for me?" The woman's mouth shifted. "You want to see him in a market where your badge is paper? You follow a man into a place built on debt and secret, that's your choice. The door doesn't make it safe." Quinn's shoulders had stopped shaking, but the cold had moved into her bones. Eighteen years of procedure. Crime scene first. Backup. Warrant. Chain of custody. The city had soaked those things through, and the rain would take what remained. Morris's final words sat folded in her coat pocket. The paper had worn at the crease from her thumb. The woman lifted the board from her lap. "Token." Quinn dropped the bone into the hand. The gatekeeper turned it against the light, inspected the mark, then reached beneath her coat and produced another, longer, yellowed, tied with black cord. She handed it across. "Hold that at your throat. Walk two minutes down the first corridor. Do not touch goods. Do not take photographs. If the men at the stalls know you are police, they will not care." Quinn took the cord. "If they don't know I'm police?" "Then learn what you can before they do." The light at the bottom of the stairs blinked. Somewhere beyond it, Herrera's voice carried, too low to make words, followed by the hiss of rain dropping onto an iron grating. "Full moon," the woman said, closing the door against the street. "So we're under Camden. Last month it was Whitechapel." Quinn climbed the steps. Each one rang under her heel. The street noise faded, sirens, wet tyres, the cough of a motorcycle. The air thickened with incense, sweat, and cold stone. The token's cord rubbed the skin of her neck. At the bottom, the old platform had been broken into stalls. Green cloth hung over tiles. Glass jars sat on wooden crates. A man with gloves sold folded maps from a tray. A woman arranged vials in a case lined with dark velvet. A table held animal teeth drilled through with wire, and beside them, cards with prices written in a hand Quinn did not recognise. Herrera stood twenty feet ahead, talking to a figure behind a counter. The medical bag rested on the counter. He touched his forearm, the scar pulling under the cuff. The figure answered by pushing the bag toward him. A vendor beside him glanced toward the door, then at Quinn. His gaze snagged on the black cord, then slid to Herrera. Herrera lifted his chin. His warm brown eyes found her across the stalls. Quinn did not slow.
