The rain came sideways down Frith Street, turning the tarmac into a smear of green and red neon. Quinn ran through it with her coat open, radio dead in her pocket, one hand braced against her ribs where the man had put an elbow six streets back. Ahead of her, Tomás Herrera cut left at the crossing and nearly went down on the wet kerb. He caught himself on a bollard, spun, and looked at her. That was the thing that kept her running. Not the fleeing — anyone ran from police, that was practically a civic tradition in Soho — but the look. Not guilt. Something closer to apology. "Herrera!" She shouted it into the rain. "You've been running eleven minutes. I've been running eighteen years. Do the maths." He went right, past the shuttered fabric shop, past a hen party spilling out of a doorway in matching pink sashes. Quinn shouldered through them. Someone screamed at her about her shoes. She kept the curly dark head in sight, bobbing between umbrellas, the pale flash of a bandaged forearm. She'd found him in the back of a flat above a dry cleaner's on Bateman Street, stitching a stab wound in a woman's shoulder with a curved needle and dental floss. No gloves. No paperwork. Six vials of something the colour of engine oil lined up on the kitchen counter and a Saint Christopher medallion swinging over the woman's collarbone as he bent to work. The woman had been up and walking within thirty seconds of Quinn kicking the door. Walking. With eight centimetres of open muscle in her deltoid. Quinn had eighteen years of decorated service and she had watched that happen, and there was no box on any form she knew how to tick for it. Herrera hit Charing Cross Road and the traffic swallowed him. Horns. A cyclist bailing into a puddle. Quinn timed the gap and went through the middle of it, palm slapping the bonnet of a black cab, the driver's mouth working behind the glass. "Police," she said, to nobody. Her lungs burned. Forty-one years old and she'd taken the stairs at the station for a decade specifically so this moment wouldn't hurt, and it hurt. North. He was going north. Past Foyles, past the crowds, and the crowds thinned as the theatres emptied and the streets narrowed into the wet dark behind Tottenham Court Road. She lost him at a corner, found him again by sound — trainers on standing water, that slap-slap rhythm, unmistakable. By the time she reached Camden the rain had stopped being weather and started being a condition. Her hair was flat to her skull. The leather watch strap on her left wrist had gone slick and cold, and she kept looking at it because she needed something with numbers on it, something that behaved. Herrera slowed. That was the first wrong thing. He stopped at the mouth of a hoarded-off building site on a street Quinn couldn't name, hands on his knees, chest heaving. He looked back at her — twenty metres, maybe less — and he was smiling. Not a taunt. The smile of a man who'd reached the top of a hill. "Don't," he said. Spanish under it, the vowels rounder than the rain. "Detective. Seriously. Don't." "Don't what." She kept walking. Slow. Hands loose. "Don't arrest you? That ship's already in the harbour, Tomás." "Don't come down." He pulled a sheet of plywood aside like a curtain. Behind it, a set of tiled stairs went into the ground, and the tiles were the wrong colour — that cream and oxblood of a Tube station that hadn't seen a train since her mother was in nappies. There was no roundel. No signage. Just the throat of it, and a green glow coming up from below that was not the green of an emergency light. "You're going into a disused station," she said. "Which is trespass, criminal damage, and about nine health and safety violations I'll enjoy reading out to you." "I'm going home." Herrera wiped rain off his face with his forearm. The bandage was pink now, soaked through. "You go to a hospital, you fill in a form. I go to the Market. It's the same thing. It's just that mine doesn't have a car park." "The Market." "You don't have a token." He said it gently, and that gentleness landed harder than a threat. "You go down there without a token, Detective, and nobody sells you anything. They sell you. Do you understand what I'm saying to you?" "No," Quinn said. "That's precisely the problem. I haven't understood a single thing since half nine this evening." He went down. She stood at the top of the stairs with the rain running off her nose and the plywood swinging on one nail, and she thought about DS Morris. Three years, four months. A Tuesday. Morris had gone into a stairwell in Deptford ahead of her because he always went in ahead of her, and she'd heard him say — clearly, calmly, in the voice he used for lost children and drunk students — *oh, you're not meant to be here.* Then nothing. Then a smell like hot copper. Then a stairwell with nobody in it and no exit but the one she was standing in, and eleven months of interviews in which she'd said *I don't know* until the words stopped meaning anything, until Professional Standards wrote *unexplained* on a document and filed the whole of him away. She'd carried that word around like a stone in her shoe ever since. *Unexplained.* As though it were a kind of answer. Down there, a woman with an open shoulder had stood up and walked. Quinn took her phone out. No signal. Of course. She typed the address into a note anyway — *Camden, hoarding, disused stn, Herrera T., 23:41* — and put it back in her pocket, and understood, doing it, that this was a ritual and not a precaution. Bread crumbs for nobody. Procedure said call it in. Procedure said wait for units, wait for a structural assessment, wait for a warrant, wait, wait, wait, and by then Herrera would be a rumour and whatever was down those stairs would have moved, because Herrera had said *moves* — no, he hadn't. He'd said *the Market*, and something in the way he'd said it, capital letter and all, meant it went somewhere else when it wanted to. There would not be another Tuesday. There would not be another chance to be at the top of the stairs. She thought: I have a warrant card and a can of spray and forty-one years of being reasonable. She thought: none of that helped Morris. The green light pulsed. Not flickered — pulsed, slow, like something breathing at the bottom of a well. Underneath it, faint, she could hear noise she recognised and couldn't place: the specific hum of a lot of people bargaining in a confined space. A tube of sound. Somewhere down there a bell rang three times and a hundred voices dropped to nothing and then came back up all at once. Quinn wiped her palm on her sodden coat, which achieved nothing at all, and put her hand on the tiled wall. "Right," she said. She went down two steps. The rain stopped touching her. Not stopped falling — stopped *touching her*, as though the stairwell had drawn a line and the weather respected it. The air came up warm and thick and smelled of salt, tallow, wet fur, and something sweet enough to make her back teeth ache. Three steps. Four. The green light found her hands and made them look like a stranger's. Behind her, the plywood swung shut with a sound like a shop door, and the little bell she hadn't seen jangled somewhere above her head, and every voice in the dark below her went quiet at once.
