Rain came down in sheets across Camden High Street, turning the tarmac into a black mirror that shattered under every footfall. Quinn ran through it with her coat open, her radio dead in her pocket, and the shape of Tomás Herrera thirty metres ahead of her, cutting between a bus shelter and a shuttered kebab shop. He was fast. Faster than a man carrying a courier bag had any right to be. He'd taken the corner off Kentish Town Road without slowing, and she'd lost half a second on the wet kerb, one hand slapping the wall of a Tesco Express to keep herself upright. Her watch strap had gone slick against her wrist. Her lungs burned in that specific way that reminded her she was forty-one and hadn't run the sprints since Hendon. "Herrera!" She shouted it into the rain and didn't expect it to land. "Tomás! Stop!" He looked back. That was his mistake and she filed it away, because in that half-turn she saw his face clear under the streetlight — olive skin, water streaming off his jaw, and something around his neck catching the amber glow. A medallion on a chain, bouncing against his collarbone. Saint Christopher. Patron saint of travellers. Fitting. He put his head down and went left into the mouth of an alley that Quinn knew, because she'd walked this beat for two years before she made DS, ended in a brick wall and three commercial bins. She allowed herself a breath. Something like satisfaction settled in her chest as she took the corner, one hand already going to the cuffs at the back of her belt. The alley was empty. She stopped dead. Water hammered the bin lids, a flat industrial percussion. The wall at the end was exactly where she remembered it, unhelpful and solid, tagged over with three generations of graffiti. No fire escape. No doorway. A drainpipe too narrow and too rusted to hold a grown man's weight. "No," Quinn said. She swept her torch across the ground. Puddles. A crushed can. And there, in the corner where the wall met the terrace, a rectangle of deeper black where the paving had been lifted and set aside — a service hatch, iron, propped open at forty degrees against the brick. She crouched. Cold air came up out of it, and it didn't smell like sewage. It smelled like a Tube tunnel: dust, brake iron, warm electric. And under that, something floral and rotten, incense left too long in a damp room. There were rungs. Someone had welded them in, and they weren't old. Quinn stayed on her heels and did the arithmetic she'd been trained to do. No radio signal — she'd checked twice since Chalk Farm and got nothing but static, which was its own kind of information. No backup, because she hadn't logged this as a pursuit, because she hadn't logged any of the last six weeks, because the moment she put Herrera's name in a case file next to the words *Raven's Nest* she'd be in front of a DCI explaining why a decorated detective was building a wall of red string in her spare room. Eighteen years. Commendations. A file so clean it squeaked. And a partner in the ground. Morris had gone into a basement in Deptford on a Tuesday night in November and come out on a coroner's table with a report that said *cardiac event* and photographs that said something else entirely. Frost on the inside of a warm room. Her partner's hands curled like he'd been holding on to something. Quinn had read that report eleven times and every reading was a hole in the world she couldn't stop putting her hand into. Herrera knew something. She was certain of it in the way she was certain about very little anymore. Former paramedic. Struck off by the NHS for reasons the tribunal minutes described as *administering unauthorised treatments* and then, curiously, redacted for four consecutive paragraphs. He'd been in the Nest three times in the last fortnight. He carried a bag full of things that weren't in any formulary she could find. The hatch breathed cold at her. "Right," Quinn said, to nobody, and swung her legs into the dark. The rungs were slick. She went down twelve of them with her torch clamped in her teeth and her coat catching on the frame, and dropped the last metre onto concrete that rang hollow. The rain became a distant hush above her, like a crowd in another room. She was standing on a platform. Actual platform, tiled, with the curve of a tunnel mouth at each end and a strip of ancient enamel signage still clinging to the wall in cream and blue letters half-eaten by damp. She got two of them: *SO*—something—*RN*. There were no rails. The trackbed had been floored over with pallets and boards. And there were lights. Not electric. Down the length of the platform, hung from the ceiling on wire and from stanchions on hooks, dozens of glass jars glowed a low fungal green, the colour of the neon above Silas' door, the colour of nothing that grew in England. They lit stalls. Trestle tables. Tarpaulins strung as awnings. A tin sign hand-painted with a crescent moon. Somewhere down there a man was laughing, and a woman was singing something with too many syllables in it, and a hundred quiet voices layered into the murmur of a market that should not have existed forty feet under Camden. Quinn switched off her torch. It felt suddenly like walking into a room and turning on the lights during someone's funeral. She could see Herrera. He'd stopped at the top of the stairs at the far end, hands on his knees, chest heaving, and now he straightened up and looked back along the platform at her. Two hundred metres. Between them, a market full of people who turned, one at a time, to see what he was looking at. A boy at the nearest stall put down a mortar and pestle. He was maybe nineteen, and his eyes had no whites at all. Quinn's hand went to her hip and found nothing there worth finding — a warrant card, a phone with no signal, cuffs. She'd left her stab vest in the car in a fit of confidence she was already revising. "You shouldn't be here." Herrera's voice carried, and it carried strangely, arriving thinner than it should have. "Detective. *Detective.* Turn around." "Come here and say it to my face." "I'm saying it from here so you live." He wiped rain off his mouth with the back of his wrist. "You don't have a token. You know what that means? No, you don't. That's the whole problem with you people, you come down without knowing—" A woman stepped out from behind the tarpaulin nearest Quinn. Tall, in a butcher's apron, holding a curved knife she wasn't using on any meat Quinn could see. She said something. Not in English. Not in any language Quinn had heard on the High Street, and Quinn had heard most of them. "She's asking if you're bringing an offering or if you're the offering," Herrera called. "I would answer carefully." Quinn stood on the tiles with rainwater running out of her hair and down the back of her collar, and behind her the rungs went up into an alley with brick walls and bins and a beat she understood. She thought about Morris' hands. Curled. Holding on. "Tell her," Quinn said, and got her warrant card out and held it up so the green light caught the crest, "that I'm buying." The butcher looked at the card. Then she laughed — a wet, delighted sound — and stepped aside, and the market opened up in front of Quinn like a throat. Herrera swore in Spanish and started walking back towards her.
