The rain had been going since four, and by half eleven it had worn the city down to a slick black shine. Quinn stood in the doorway of a shuttered dry cleaner's on Berwick Street with her collar up and her hands loose at her sides, watching the green neon of The Raven's Nest bleed across the wet pavement forty feet away. Green light. She'd started to hate that colour. Eleven nights she'd given to this door. Eleven nights of takeaway coffee and numb feet and a notebook full of faces she couldn't put names to, of people who went in and didn't come out, or came out looking wrong — pale, or too bright-eyed, or moving like something had been taken out of them and something else put back. Her governor had asked her twice now, gently, whether she was sleeping. Gently was worse than shouting. Gently meant paperwork was being prepared somewhere. At 11:34 by the worn leather watch on her left wrist, the door opened and Tomás Herrera came out. She knew him instantly. She'd built him out of scraps — a hospital HR file, a struck-off notice from the HCPC, a witness statement from a stabbing in Deptford where the victim had survived injuries the paramedic's own notes described as unsurvivable. Twenty-nine. Olive-skinned, short curly hair going flat in the rain. He carried a canvas satchel across his body like a man who'd been taught to protect it. He also, she noticed, checked the street the way she did. Left, right, upper windows. His eyes stopped on the dry cleaner's doorway. There was a half-second — she'd think about it later, that half-second, the way you think about a stair you nearly missed — where he simply looked at her and she looked back, two people acknowledging a shared piece of information. Then he ran. "Police!" she shouted, already moving. "Herrera! Stop where you are—" He was fast and he knew the geometry of Soho, which was worse. He went right, into the mouth of an alley she'd walked past nine times and never gone down, over a stack of crates, through a beaded curtain into the back of a restaurant kitchen. Quinn came through six seconds behind him into wet heat and shouting, a wall of steam, a man in whites holding a stockpot and screaming something in Cantonese. She kept her feet on the greasy tiles because eighteen years had taught her exactly how to run on a bad floor, shoulder low, weight forward, and she came out the other side onto Wardour Street with her lungs already burning. He was thirty metres up, arms pumping, satchel clamped under one elbow. She hit the radio at her shoulder. "Control, this is DI Quinn, I'm in foot pursuit northbound on Wardour, male IC3, dark jacket, requesting units—" "—say again, Quinn, you're breaking up—" Of course she was. She always broke up around this lot. She'd stopped believing in coincidence about a year ago and now she just filed it, one more grain on the pile. He took Oxford Street at a diagonal through traffic. A taxi hauled sideways and blared and she went through the gap behind it close enough to feel the heat of the bonnet on her thigh. Rain came at her in sheets under the streetlights, silver and then gold and then silver again. Her coat was three stone heavier than it had been at four o'clock. She'd smoked for eleven years and quit for nine and she could still feel the ghost of it, a hand around her ribs, squeezing. Northbound. Fitzrovia. Then the long dark stretch up towards Camden, past the shuttered fried chicken shops and the scaffolding and the men in the doorway of the Lord Palmerston who cheered as he passed and cheered louder when she did. He didn't try to lose her. That was the thing that started to bother her, somewhere around Mornington Crescent, when the stitch in her side had become an actual knife and her breath was coming in tearing gulps. He kept looking back. Not with panic. With something closer to calculation. Checking she was still there. *He's herding you*, said the part of her brain that sounded like DS Morris. Morris had had a voice like a Radio 4 announcer and a laugh like a drain. Three years ago Morris had gone down a set of stairs in Rotherhithe ahead of her and she had followed nine seconds later and there had been nothing at the bottom. Not a body. Not a door. A dry basement, four walls, and Morris's warrant card sitting in the middle of the floor, absolutely flat, absolutely centred, as if placed. She had written *lost contact with subject* in her statement because there were no words in the English language for the other thing. Herrera cut left off the high street into a service road behind a row of lock-ups. Quinn followed and nearly went down on her hands — the tarmac was covered in something slick and dark, and the smell hit her, wet iron and burnt sugar. Ahead, at the end of the road, was a hoarding: blue plywood, faded planning notices, TRANSPORT FOR LONDON, DANGER DEEP EXCAVATION. He didn't slow down. He hit the hoarding at a run, and a panel swung inwards on hinges she couldn't see, and he was gone. Quinn stopped. She stood in the rain with her hands on her knees and made herself breathe, four counts in, four out, the way the force psych had taught her for other purposes entirely. The panel had swung shut. From here it looked like plywood. It looked like nothing. Water ran off the end of her nose. She straightened and put her palm flat on the wood and felt, through it, faintly, a vibration. Not a train. Trains had rhythm. This was more like a crowd. Like a market hall, four hundred voices going at once, coming up from a long way down. She knew what was under here. Everyone who'd worked London long enough knew about the disused stations, the war-time deep shelters, the tunnels that didn't appear on any public map. What she didn't know was why her hand didn't want to be touching the wood. *Radio it in.* She keyed the mic. Static, thick as porridge. She looked at her phone: no bars, and the clock reading 11:34, which was wrong, which was the time she'd looked at her watch outside the bar, and she felt something cold go down her spine that had nothing to do with the rain. Her watch said 12:02. She chose to believe the watch. Right. So. Options. Option one: back off, mark the location, come back at ten in the morning with a warrant, a van, and four officers who would look at the blue plywood, look at her, and find nothing behind it, because she had already learned what happened when she brought other people to places like this. Nothing was ever behind it. And then the gentle conversations would stop being gentle. Option two. Quinn put her fingers into the gap at the edge of the panel. It was warm. She thought about Morris's warrant card lying flat in the middle of a clean floor. She thought about the eleven nights, and the file with no names in it, and the fact that she was forty-one years old and had precisely one thing left that she wanted, which was to know. She pulled the panel open. Concrete stairs went down into the dark, and the dark was not empty — there was a glow at the bottom, low and amber and shifting, and the noise of it came up at her all at once now that the wood wasn't in the way: voices, hundreds, and something being hammered, and something laughing, and under it all a low bell-note like a finger on the rim of a glass. Halfway down the first flight, a shape resolved itself in the gloom. Herrera. Standing on the landing, breathing hard, one hand braced against the wall, the other holding something small and pale between two fingers. A token, she thought. Bone. "Don't," he said. Spanish under the London, warm and ragged. "Detective. *Please*. Don't come down." "You knew my name," Quinn said. Her voice was steadier than she'd expected. "Back on Berwick Street. You clocked me and you knew who I was." "Everybody knows who you are." Rain dripped off him onto the concrete. Around his neck, a Saint Christopher medallion had swung free of his collar, catching the amber light. "That's the problem I've been trying to solve for four months." "I'm coming down." "You don't have a token." He held his up. "You can't get in without one. And if you go in without one, they'll—" He stopped. His jaw worked. "There are things down there that will take an interest in you. That's not a threat, that's — that's triage. I'm telling you what the injury will be." Quinn came down two more steps. On the landing wall, someone had painted a symbol she'd seen once before, in a basement in Rotherhithe, and her hands went cold and steady, and she said, very quietly, "Three years ago I lost my partner. There was a mark like that one on the wall." Something moved across Herrera's face then. Not surprise. Recognition. Which was, she understood in that moment, the single most dangerous thing she'd seen all night. "*Dios*," he said softly. "You're the one from Rotherhithe." Below them, the bell-note sounded again, and the amber light shifted, and the market breathed. Quinn took the last four steps.
