The rain had settled into the kind of steady, indifferent drizzle that made London look like an old photograph of itself. Harlow Quinn kept her distance across Camden High Street, one hand in the pocket of her long grey coat, the other resting near the worn leather strap of her watch. The hands read twenty past eleven. Tomás Herrera had not looked back once in the last ten minutes, which told her he didn't think he was being followed, or that he had stopped caring. She had been watching him since Soho. The green neon above the Raven's Nest had buzzed behind her as he stepped out, collar up, a hand pressed flat against his chest as if to steady something beneath his shirt. She had seen the glint of metal at his throat under the streetlight. A Saint Christopher, the kind sold in tourist shops along the Thames. The kind of thing a man kept when he had nothing else he trusted. He cut left past the closed shutters of a record shop and onto a side street that ran downhill toward the canal. Quinn quickened her pace. Her shoes found the slick cobbles and she adjusted without thinking, the way she had adjusted on a thousand wet nights over eighteen years. Military habit. Her father had called it precision. Her last commanding officer had called it a fault, because it made her predictable. The street narrowed. Iron railings, a dead streetlamp, the smell of wet brick and river mud. Tomás slowed at a boarded-up entrance set into the hillside, a squat stone arch above a stairway that dropped into darkness. The sign had been painted over years ago, but the letters still ghosted through: UNDERGROUND. Someone had chained the grille. Someone had also cut the chain. Quinn stopped at the corner and pressed her back to the wall. Her pulse was steady. It always was, until it wasn't. Tomás reached into his coat and drew out something pale that caught the light. A small carved disc, yellowed, the size of a coin. He held it up to the gap in the boards, almost reverently, and the air beyond the arch shivered. There was no other word for it. The darkness stirred like water disturbed by a stone, and a faint sound drifted up the steps: music, distant and wrong, a reedy tune played in a key she didn't recognise, underneath the rattle of voices. Three years ago, she had stood in a corridor very much like this one with DS Morris's blood drying on her glove and a witness who wouldn't stop repeating that the dead man had walked straight into the wall. The report had said gas leak. The report had said a lot of things. Quinn had written most of them herself, and she had never believed a single word. She took a breath and started forward. Tomás was already descending. She reached the top of the steps just as he turned at the bottom, and for a second their eyes met across the distance. He didn't look surprised. He looked tired, and he looked resigned, and then he looked past her shoulder with a flicker of fear that she didn't like at all. "Detective," he called up, his voice carrying strangely in the stone. "You should go home." "You're under arrest for the Halloway assault," she said. "Step away from the door and put your hands where I can see them." He laughed, short and humourless. "There's no door, Detective. Not for you." The arch was closing. She could see it happen, the darkness drawing in like a curtain, the cold air rising to meet her face with a smell of old iron and something sweeter underneath, like lilies left too long in a vase. Her hand went to her hip out of habit, to a holster that held nothing that would matter down there. Behind her, a bin lid clattered in the alley. She did not turn. Someone was watching from the rooftops; she could feel it on the back of her neck, the same prickle she had felt the night Morris died. Options presented themselves with brutal clarity. She could radio it in. She could wait at the top of the steps for backup that would take forty minutes to arrive and would find nothing but a chained grille and a dead end. She could walk away, go home, and wake tomorrow with another file marked closed. Or she could go down into the place that had taken her partner and find out what it had done with him. Quinn checked the watch on her left wrist. Twenty-three minutes past eleven. The music below rose and fell, and somewhere a crowd murmured in a language that might have been English if she had listened harder. She stepped onto the first stair. Then the second. The arch sealed above her with a sound like a held breath released, and the rain fell away behind her as if it had never existed at all.
