The rain had come in off the canal an hour earlier and hadn't let up since. It hammered the awnings of Camden High Street and ran in black ribbons down the gutters, and Harlow Quinn ran through it with her coat open and her warrant card cold in her fist. Ahead, the man in the dark jacket cut left past a shuttered kebab shop and vanished into the mouth of an alley. Tomás Herrera. Former paramedic, struck off, currently the most useful pair of hands in a city full of things that bled wrong. She had watched him stitch a man's throat in a Soho back room eleven days ago, and she had watched the man's throat close up under his fingers like a zip. She had not written any of it down. That was the first mistake she had made in three years, and she intended it to be the last. She took the corner hard. Her boots skidded on painted metal. The alley was narrow, walled by corrugated hoarding and the blind backs of warehouses, and it smelled of wet cardboard and diesel. Halfway down, a stack of pallets had been pushed aside. Beyond it, a gap in the hoarding showed a rusted gate hanging from one hinge. Her left wrist was wet where the leather strap of her watch had darkened. She glanced at the dial out of reflex. Twelve minutes past midnight. Eighteen years in the Met had taught her the value of a timestamp, and the value of never letting a suspect set the pace. "Herrera!" Her voice bounced off brick. "Police. Stop where you are." Nothing answered her but the rain and the faint, sweet hum of a generator somewhere behind the wall. She pushed through the gap. Beyond the gate, a set of concrete steps sloped down into a throat of darkness. Someone had painted a sign over the arch, long since flaked to ghost-letters: CAMDEN TOWN, and beneath it, in a newer hand, scratched into the tile with what looked like a nail, a small white symbol she didn't recognise. A bone, or a stylised version of one. Fresh chalk lay in a line on the lowest step, unsmudged, as if someone had laid it there that evening. The tunnel below was lit by a string of bulbs that flickered and steadied, flickered and steadied. She could hear voices now, a murmur of many people, and a burst of laughter that was not quite human in its pitch. Then, closer, the scuff of a shoe on tile. Herrera's shoe. She'd have known that gait anywhere by now. She took the first step down and stopped, because her body stopped her. Three years ago, in a flooded basement off the Old Kent Road, she had gone down a set of stairs after Ray Morris. She had heard him call her name from below, and she had gone down, and when she reached the bottom there had been nothing there but his torch lying on the wet floor, still burning, and a smell like struck matches and something sweeter underneath. They had never found him. The official report said he had absconded under suspicious circumstances. The truth was in her notebook, and the notebook was full of things she had no words for. Her hand went to her hip, to the radio. She thought about calling it in. Who would she call? Her Superintendent, who had already asked her twice whether she was sleeping? The rest of the Met, who would find a chalk symbol and a tunnel full of noise and conclude she had lost her mind? Morris's brother, who still sent her Christmas cards? She thought about the bone token she did not have, and the fact that the chalk on the step was clearly a mark for people who did. Below, Herrera spoke, low and unhurried, to someone she could not see. "She's not supposed to be here," he said. "Not yet." A woman's voice answered, amused. "Then she's either very brave or very stupid. Which one are you banking on, Tommy?" Quinn breathed in. Rain ran off the end of her nose and dropped onto the step. She could go back up the alley and wait for the morning. Herrera would surface eventually, or he wouldn't. The clique would keep doing whatever it did behind its locked doors, and she would keep a list of names that no court in England would accept. Or she could go down into the place that had swallowed her partner and see what it wanted from her. Quinn unbuttoned the second button of her coat, moved her hand away from the radio, and started down the steps, one measured stride at a time, the way she had been trained to walk into rooms where the danger had not yet declared itself.
