The rain came sideways off the Thames, needling through the collar of Harlow Quinn's coat as she cut across Shaftesbury Avenue at a dead run. Her boots struck the wet asphalt in a hard, even rhythm — a rhythm she'd learned at nineteen and never lost — and somewhere behind her a car horn blared uselessly into the dark. Ahead of her, forty yards and closing, the man in the olive jacket vaulted a row of bollards and vanished down a service lane between two darkened restaurants. Quinn didn't slow. She'd clocked him on Greek Street twenty minutes ago, moving with the furtive efficiency of someone who knew he was being watched, and she'd watched him anyway, because that was the job. When he'd spotted her reflection in a shop window and bolted, the night had become very simple. He was fast. Faster than her, if she was honest, and younger by a decade. But she had run down faster men in worse weather, and she had the advantage of knowing what he didn't: that every street in Soho was a dead end if you pushed it hard enough. The lane narrowed. Steam bled from a vent above a kitchen door, and the smell of old grease and wet brick filled her mouth. She saw him at the far end, shoulder-checking a fire door, spilling out into the sodium glare of a back court. She put her hand flat against the wall as she turned, using it for leverage, and her worn leather watch caught the light — the second hand sweeping past the nine, indifferent to all of it. "Police!" she shouted, because you shouted it, even when your lungs were burning and the man could not have heard you over the rain. "Stop!" He didn't stop. They never stopped. The back court opened onto a construction site, and he went over the hoarding in a scramble of limbs, tearing his jacket on a nail. Quinn went through the gap he'd made rather than over it, ducking low, and came up with her torch in her hand. The beam sliced through the downpour, catching scaffolding, a half-dug trench, the pale of a cement mixer. Mud sucked at her shoes. Then she saw where he was headed, and something cold turned over in her chest. The hoarding on the far side was tagged with a spray of symbols she didn't recognise — a spiral, a pair of crossed lines, a mark like a keyhole. Beyond it stood the dark mouth of the old Camden Town station, the one that had been closed since before she was born, boarded and bricked and left to rot beneath the northern line. Except the boards had been pulled away. Except there was light down there, faint and yellow, and the smell of incense, and a low murmur of voices that had no business existing at two in the morning in a condemned Tube station. The man — she had a name for him now, Tomás Herrera, from the file she'd read three days ago and shouldn't have had — ducked through the gap and was gone. Quinn stopped at the threshold. Rain drummed on the hoarding behind her. The torch beam found the first steps of the escalator, and she saw them: bones. Small ones, wired together with red thread, hung in bunches from a rusted handrail like wind chimes. They turned gently in a draft that came up from below, and the sound they made was not quite a rattle and not quite a chime. She thought of Morris. She thought of him more than she told anyone, and always at moments like this — the threshold moment, the point where a case stopped being a case and became something with teeth. Three years ago he'd gone down a stairwell not unlike this one. She'd been two minutes behind him. Two minutes. They'd found his radio at the bottom, still transmitting, and they'd found his coat, and they had never found him, and the report had used the word *unexplained* in a way that meant *don't ask*. Her hand went to her left wrist and turned the watch, a habit as old as the watch itself. Then she keyed her radio. "Control, this is Quinn. I'm at the old Camden station, north entrance. Suspect has entered the structure. Requesting backup, immediate." The radio hissed. A woman's voice, thin and bored, came back: "Received, Detective. Units are twenty minutes out. Do not pursue into an unsafe structure. Repeat, do not pursue." Twenty minutes. In twenty minutes Herrera would be a rumour. Quinn clipped the radio back to her belt and stood in the rain with her jaw set, and she was aware — with the clarity that came to her only in the worst moments — that she was forty-one years old, that her knees hurt, that she had made a promise to a widow in a hospital corridor three years ago that she would find out what happened, and that every promise she had ever kept had started exactly like this, at the top of some stairs she had been told not to descend. "Right," she said, to no one. She went down. The escalator had been stripped to its frame; the steps were wood, nailed across. She took them slowly, torch off, letting her eyes adjust to the yellow light that leaked up from somewhere below. The air changed as she descended — warmer, thicker, carrying a smell of candle wax and iron and something sweet underneath, like overripe fruit. The bone chimes turned as she passed, and she felt their attention on her, and refused to give it a name. At the bottom, the platform had become a street. That was the only word for it. The old tiles were still there, cracked and black with damp, but between the tracks and along the platform edge a market had grown up like fungus after rain: stalls built of scavenged timber and tarpaulin, hung with lanterns that burned a colour that was almost green. People moved among them — and they were people, she was nearly sure, though some were too tall and some moved too smoothly, and none of them were looking at her the way people looked at a police officer. Quinn stepped off the last stair and the noise of the market did not stop, but it changed. A tuning. A settling. She was aware of herself as an intrusion, the way you are aware of a wrong note in a piece of music. She found Herrera at the third stall. He had his back to her, arguing in low Spanish with a woman whose hair was bound up in copper wire, and he was holding something small and pale in his hand — a token, a knuckle of bone with a hole drilled through it. "Herrera." He turned. The fear on his face was real, and so was the anger underneath it. The scar on his forearm showed where his sleeve had torn. Around his neck, the Saint Christopher medallion glinted. "You shouldn't be here," he said. "You really, really shouldn't." "You're going to want to come back up those stairs with me." Quinn kept her voice flat, her hands loose at her sides. "We can talk about the man in the hospital, and the prescriptions that don't exist, and whatever it is you've been doing for the last six months. Or we can do it down here. Your choice. But you're not walking out of this station alone." For a moment — she would swear to it later — the man looked at her with something like pity. Then the copper-haired woman said a word in a language Quinn didn't know, and every lantern in the market went out at once. The dark was absolute. Quinn dropped into a crouch out of instinct, her hand going to her radio, and the radio was dead, and the air was full of the sound of a great many people moving very quietly in the same direction. She had a choice to make. She had been making it, she realised, since the top of the stairs. She stood up, drew her torch, and switched it on. The beam found a wall of faces — not hostile, exactly. Curious. Ancient in a way that made her stomach cold. And somewhere behind them, somewhere in the tunnels that ran beneath the whole of her city, Tomás Herrera was already gone. Quinn turned the watch on her wrist, once, and walked forward into the market. "Right," she said again, quietly, to the dark. "Let's have it, then."
