The rain had been falling since dusk, and by eleven it had soaked through the shoulders of Harlow Quinn's coat and found the gap at her collar. She didn't feel it. Her eyes were on the man ahead, a dark shape cutting across Camden High Street, weaving between a bus shelter and a knot of smokers who scattered from his path. Tomás Herrera ran like a man who had once been trained to carry weight through crowds. Even at this distance she could see the set of his shoulders, the rhythm of a body that knew where every obstacle would be before it arrived. Her left wrist ached where the worn leather watch pressed against the bone. She checked it out of habit. Eleven-oh-four. Eighteen years on the job had given her a habit for everything. "Herrera, stop!" Her voice carried, flat and hard, the voice she used in interview rooms. He did not stop. He glanced back once, his face pale under the sodium lamps, and then he was past the bus shelter and turning sharply into Camden Lock Place. She followed, boots striking the wet pavement in a controlled rhythm. Her radio hissed in her coat pocket. She ignored it. Backup was twelve minutes out at best, and twelve minutes was a lifetime when the man you were chasing had just walked out of a surveillance file with two dead informants in his wake. The lane was narrow, lined with shuttered stalls and the dripping canvas of market awnings. Halfway along, Herrera vaulted a low railing and disappeared behind a row of bins. Quinn reached the railing and stopped, breath steaming in front of her. Beyond the bins was a service yard, and beyond that the black mouth of an old ventilation shaft, its iron grille hanging open on one hinge. She drew her weapon and kept it low. Her pulse was steady. It always was, the way Morris used to tease her about, saying she could be shot at and still reach for the sugar. Three years ago Morris had walked into a basement in Hackney with a warrant and a torch, and he had walked out of her life without a body to bury. The coroner's report had used the phrase *unexplained circumstances*. She had read it so many times she could recite it. What the report had not explained was the smell that clung to the basement walls, sweet and metallic, like wet coins in a jar of honey, or the way the security footage had gone white for four minutes and then resumed with nothing in the frame at all. She had spent three years building a case against the people who had been in that basement. Herrera was the first thread that had come loose. She stepped over the railing. The yard was slick with oil and rain. At the shaft she crouched, angled her torch down, and saw the metal rungs descending into a dark that seemed to swallow the light rather than reflect it. Something glinted on the wet concrete beside the grille. She picked it up. It was small, smooth, and pale, the size of a playing die, carved with a spiral of tiny symbols she didn't recognise. It was warm. Not warm from a pocket. Warm the way a stone is warm after lying in the sun all afternoon, though there had been no sun in London for a week. A bone token. She had read about them in a file she had not been meant to see, a file with no case number and a handwritten note in the margin: *Entry to the Market. Do not enter without.* She turned it over in her gloved fingers. Somewhere below, faint and distant, a bell rang once, then fell silent. Her radio crackled. "Quinn, where are you? Sarge says you're not answering." She keyed the mic. "Camden Lock, service yard. Herrera went down a ventilation shaft. I'm following." "Ma'am, wait for—" She let go of the button. The rational choice was obvious. She was a detective, not a field operative. She had no idea what was at the bottom of that shaft, no backup, no reliable map, and a token whose purpose she could only guess. A woman with eighteen years of commendations would wait at the top, call it in, and let the proper people handle it. But the proper people had not been in that basement in Hackney. The proper people had not watched a partner vanish between one heartbeat and the next. And Herrera had not run from her out of fear of a jail cell. He had run the way a man runs toward something he believes will save him, and she had seen the same look on his face that she'd seen on the faces of the dead. She slid the token into her inside pocket, against her ribs, where she could feel its faint warmth through the wet fabric. Then she took hold of the first rung, checked the watch one last time, and started down into the dark.
