Rain hammered Camden High Street so hard it bounced, a silver haze knee-high on the tarmac. Quinn ran through it with her coat flapping open and her lungs burning, eyes fixed on the dark curly head bobbing thirty yards ahead. Tomás Herrera ran well for a man who fixed people for a living. He cut between the late-night kebab queues and vaulted a bike rack without breaking stride. The Saint Christopher medallion at his throat flashed once under a streetlamp, a cheap little wink of gold. She had followed him for two hours. Out of the Raven's Nest, past the green neon that buzzed and stuttered above the door, then onto the Northern line with a newspaper held up like an amateur. He had been careful all the way. Somewhere between Mornington Crescent and the market he had stopped being careful and started being scared. That interested her more than anything else he'd done. "Herrera!" Her voice cracked off the wet brick. "Police! Stop!" He didn't. Of course he didn't. He swung left at the railway bridge and dropped down the slick steps toward the canal. Quinn took them two at a time, her left hand skimming the rail, the worn leather watch strap sliding against her wrist. Eighteen years on the Met. She'd run down muggers, arsonists, and one very fast grandmother. She was not about to lose a disgraced paramedic in the rain. The towpath was black and narrow. Water dripped from the arches in long, ropy strings. A cyclist's lamp swung past and gone, and then there was only the sound of two people breathing and the canal slapping against its stone lip. "Tomás!" She used the name deliberately, the soft version, the one his friends used. "I only want to talk!" His laugh came back thin and ragged. "You want to talk in a cell!" "I want to talk about the man with the knife! Your arm, Tomás! Who cut you?" That was a gamble. She'd seen the scar on his forearm in the file, pale and puckered, and she'd guessed it had a story. He faltered for half a step, just enough. She gained five yards. Then he was through a gap in a chain-link fence she would have sworn was solid, and by the time she squeezed after him, wire snagging her sleeve, he was crossing a gravel yard toward a squat Victorian building. Its tiled front was the color of old teeth. Boards covered the windows. Above the door, half hidden by ivy, a roundel had faded to a ghost of red and blue. A Tube station. Long dead, and not on any map she'd ever studied. Quinn slowed, one hand drifting to her hip, where her radio sat next to a holster she was not, technically, wearing tonight. This was surveillance. Off shift. Off book. Her breath smoked and the rain ran into her collar and down her spine. Herrera stood at the door with his back to her. He was fumbling something out of his jacket, something small and pale. He pressed it flat against the boards. She saw it plainly for a second. A disc of yellowed bone, no bigger than a coin, carved with a spiral. The boards shivered, and the wood seemed to breathe in. A seam of amber light opened down the middle of the door. Warmth rolled out with it, and a sound she couldn't place at first. Voices, hundreds of them, layered and eager, and under that a rhythm like a heartbeat. The smell arrived a moment later: hot sugar, woodsmoke, something like struck matches, something like copper. Herrera turned. Water streamed from his curls and plastered his shirt to his chest. He looked exhausted, and terrified, and something else she hadn't expected. He looked sorry. "Don't, Detective," he said. His accent, thinned by years in London, had thickened with fear. "Please. Go home. Whatever you think this is, you are wrong about it, and being wrong about it will kill you." "Then explain it to me." "I can't." He almost smiled. "Not because I won't." "Tomás." "Go home, Detective Quinn." He stepped through. The seam of light narrowed, and Quinn understood she had perhaps four seconds. She stood in the rain with her heart slamming and made herself think it through the way she'd been trained. No backup. No warrant. No jurisdiction she could name for a building that didn't exist. If she called it in, she'd be explaining to a superintendent why she was tailing a man on her own time, and the seam of light would be a boarded door by the time anyone arrived. If she went in, no one knew where she was. Nobody would come looking until morning, and when they did, they would find a wet patch of gravel. That was how it had gone for Morris. Three years, and she could still see the flat in Bermondsey. The door standing open. Morris's coat on the floor, his keys still in it. No blood, no body, no signal on his phone after 11:42 p.m. The inquiry called it *unexplained circumstances*. Quinn had called it a lie by people too tired to say what they'd seen in the CCTV. She had watched that footage until the pixels bled. The hallway, and Morris walking into it, and something in the corner of the frame that the camera couldn't hold onto. Something the light seemed to bend away from. She had spent three years hunting the shape of that absence. And here, at last, was a door in the shape of it. Four seconds. Three. Every instinct she'd built into herself said walk away, gather, plan, return in daylight with a team. But she also knew how these places worked. They moved. They closed. Come back tomorrow and there would be gravel and ivy and a fence with no gap in it. Two. She pressed her thumb against the watch face, an old habit, and felt the tick of it through the leather. Then she crossed the yard in four long strides and jammed her shoulder into the closing seam. It didn't feel like wood. It felt like pushing into warm water, a resistance that gave grudgingly, and for one awful moment she thought it would hold her, pin her half in and half out. Then it let go with a soft, wet sound, like a breath released. She stumbled forward into light. The door shut behind her. She didn't need to look to know that the handle she'd been reaching for was gone. A staircase of white tile fell away ahead, worn hollow in the middle by ten thousand ghost commuters. The stairwell walls were plastered with handbills in a dozen alphabets, some of which seemed to shift when she looked away. Far below, the noise swelled. A bell rang. Someone was shouting prices. Someone else was singing in a language that made her back teeth ache. Halfway down the flight, Herrera had stopped. He was gripping the rail, staring up at her, and the look on his face was not the look of a man who'd been caught. It was the look of a man watching someone step off a cliff. "You shouldn't have followed me," he said quietly. Quinn drew herself up to her full five-foot-nine, wet through, salt-and-pepper hair dripping, and let the military stillness settle over her like armor. She started down the stairs. "Then you'd better keep up," she said, "and tell me who I'm not supposed to trust."
