Rain came down in sheets across Camden High Street, silver under the sodium lamps, black where the shadows fell. Quinn ran through it with her coat flapping open and her boots throwing up arcs of oily water, and ahead of her Tomás Herrera ran like a man who had been expecting this moment for a long time. He was fast. She would give him that. A paramedic's body, lean and conditioned, and a paramedic's knack for threading bystanders without breaking stride. He'd slipped past the drunks outside the kebab shop, vaulted a bike chained to a railing, and was now cutting across the traffic on Kentish Town Road with the easy disregard of someone who had done worse things than jaywalk. Quinn's lungs burned. Forty-one was not thirty-one, and the rain had soaked through her collar so that every stride sent a cold trickle down between her shoulder blades. Her left wrist ached where the watch strap had gone soft and heavy with water. She kept her eyes on the back of his jacket — dark canvas, the hood torn at the seam — and forced her breath into a rhythm. In four, out four. Morris had taught her that, years ago, running the towpath at Limehouse before everything went wrong. "Herrera!" she shouted. "Stop — police!" He didn't even glance back. He'd heard her the first three times. A black cab laid on its horn as Tomás cut across its bonnet. Quinn skidded around the back of it, slapped a hand against wet metal, and kept going. Her radio crackled under her lapel, some dispatcher asking her twenty, but she didn't have breath to answer. He was turning. Left, off the main road, down a narrow street she didn't know the name of. Warehouses. Shuttered shopfronts. The kind of street where CCTV went to die. She turned the corner and nearly lost him. He was thirty yards ahead, silhouetted against a streetlamp that guttered and flickered, and then he did something strange. He stopped. He looked up, and around, as if checking the sky. The moon was hidden behind cloud but she knew it was full tonight — she'd noted it that morning, because Morris had been killed on a full moon, and she noted full moons now the way other people noted birthdays. Then Tomás pulled something from his pocket. Small. Pale. He looked once, directly, over his shoulder at her — and she saw his face clearly for the first time, the scar on his forearm briefly visible where his sleeve had ridden up, his Saint Christopher medal caught on the outside of his shirt — and he stepped sideways, into what she had taken to be a brick wall. He was gone. "No," Quinn said aloud, to nobody, to the rain. "No, no, no." She closed the distance at a sprint and slammed her palms against the brick where he had been. It was wet. It was solid. She ran her hand along the seams, feeling for a door, a catch, anything, and her fingers found instead the edge of something that did not quite belong to the wall. A recess. An archway, maybe, that her eyes kept sliding off. She had to look at it sideways, peripherally, the way you looked at a dim star. There were steps going down. Quinn stood at the top of them with rain running into her eyes and tried to make her training tell her what to do. Training said: radio in. Training said: do not pursue a suspect alone into an unknown structure without backup, without a warrant, without a clear idea of ingress and egress. Training said a great many sensible things, and none of them had saved Morris. Three years ago she had stood in a doorway in Whitechapel and she had waited, by the book, for the armed response unit to arrive. Morris had gone in because Morris had heard a child screaming. When Quinn had finally been allowed through the door, there had been no child, and there had been no Morris, only a room that smelled of burnt hair and a chalk mark on the floor that none of the forensic team could photograph properly. The inquest had said accidental. The inquest had said a lot of things. Quinn had not believed any of them. She pressed the button on her radio. "Quinn to control. In pursuit of suspect Herrera, Tomás, foot, off Kentish Town Road — " She looked at the street sign and found that she could not quite read it, the letters somehow wrong. " — vicinity of Camden Lock. Suspect has entered a below-ground structure. I am going in." The radio hissed static back at her. Not the ordinary static of a weak signal. A thicker sound, almost like breath. "Repeat, control. I am going in. Mark my last." Nothing. Then, faintly, very far away, a voice that might have been the dispatcher and might have been something else: "...copy, Quinn, we have your... do not..." and then the hiss swallowed it. She drew her baton. Her service did not issue her a firearm and tonight she regretted it more than usual. She thumbed the safety off the torch clipped to her belt and tested the beam against the wet bricks. The light went in and did not come out the other side, as if the dark at the bottom of the steps were drinking it. Quinn thought of Tomás Herrera's face as he had looked at her over his shoulder. Not afraid. Not triumphant. Something more like pity. That decided her. She stepped down. The rain noise cut off three paces in, as cleanly as a door closing, and she realized she could no longer hear the traffic on Kentish Town Road or the dispatcher's static or her own heart. Only her boots on the stone and, from somewhere below, the distant, unmistakable hum of a crowd — voices, laughter, the ring of coin on metal, a woman singing in a language Quinn did not know. She tightened her grip on the baton, touched the worn leather of the watch at her wrist for luck, and went down into the dark after him.
