Rain hammered the pavement of Camden High Street, turning the gutters into black rivers that swallowed the neon glow from shop windows. Harlow Quinn sprinted past a shuttered pub, her leather watch catching the light of a passing bus as she pumped her arms. Fifty metres ahead, the suspect's dark jacket flapped like a wounded bird as he cut through the crowd of Saturday night revellers. "Move! Police!" A group of teenagers spilled out of a fried chicken shop, blocking her path for a fraction of a second. She shouldered through them, hearing the thump of bass from a nearby club drowning out her shouts. The suspect vaulted a bicycle rack and disappeared round the corner of Buck Street Market. Her lungs burned. Eighteen years on the force and the chases never got easier. She rounded the corner in time to see him heading straight for the old Tube station entrance—the one that had been closed since the Blitz, its tiled walls now plastered with faded gig posters and graffiti. He didn't slow down. He went straight down the steps. Harlow hit the top of the staircase at full speed, her boots splashing through puddles that had collected on each cracked step. The smell hit her first—wet concrete and something else, something chemical and sharp that tingled the back of her throat. Emergency lighting cast the stairwell in a sickly amber glow that flickered at irregular intervals. The sound of his footsteps echoed below, bouncing off curved walls that hadn't seen a train in eighty years. She counted the landings. One. Two. The air grew colder with each descent, the kind of cold that seeped through her jacket and settled against her spine. "Stop right there!" His footsteps didn't falter. She caught glimpses of him through the gaps in the stairwell railing—dark hair, olive skin, the glint of something metal around his neck. The Saint Christopher medallion. She'd seen it in the file photos. Tomás Herrera. The paramedic who'd lost his licence under circumstances that didn't add up, the one who kept turning up on the periphery of cases she couldn't close. The stairs ended at a landing where the original platform would have been. Instead of tracks, a narrow corridor stretched into darkness, its walls lined with pipes that hummed with some kind of energy. The ceiling was lower here, forcing her to duck her head, and the amber emergency lights had given way to something else—bioluminescent strips that pulsed with a pale green glow, like the veins of something alive. Herrera hadn't stopped. She could hear him ahead, his breathing ragged but his pace steady. He knew where he was going. She didn't. The corridor opened into a space that made her stop dead. It shouldn't have existed. The geography didn't work. They'd descended maybe sixty feet, but the cavern stretched wider than the street above, its ceiling lost in shadow. Stalls crowded the space—hundreds of them—constructed from salvaged materials and draped with fabrics that shifted colours when she wasn't looking directly at them. The air tasted of incense and ozone. Voices murmured in languages she couldn't identify, punctuated by the clink of coins and the hiss of something boiling. The Veil Market. The name surfaced from a informant's rambling testimony she'd dismissed three years ago, back when she still thought the world operated according to rules she understood. Herrera stood at the edge of the market proper, no longer running. He'd turned to face her, chest heaving, rainwater dripping from his jacket onto the stone floor. The scar on his left forearm caught the green light as he raised his hands in a gesture that wasn't quite surrender. "You shouldn't have followed me down here, Detective." "I'm not leaving without you." "You don't understand what this place is." "I understand you're a person of interest in three open investigations. I understand you just led me on a chase through half of Camden. What I don't understand is how any of this is possible." A vendor at the nearest stall—a woman with silver threading through her hair and eyes that reflected light like a cat's—watched their exchange without expression. Around her, the market continued its commerce, unhurried, as if a police detective stumbling into their midst was merely a mild diversion. Herrera took a step back toward the stalls. The crowd behind him shifted, creating a gap that hadn't existed a moment before. "If you come further, you can't unsee it. You can't go back to pretending the world works the way you think it does." "I stopped pretending three years ago." The words came out harder than she intended. DS Morris's face flashed behind her eyes—his desk, still cluttered with case files the morning after he disappeared, his coffee gone cold, his car found abandoned in an alley with the engine running and the doors locked from the inside. The case that had cracked something open in her understanding of the world, a wound that never properly healed. Herrera's expression changed. Something like recognition crossed his features. "Morris. You were his partner." "You knew him?" "I patched him up. Twice." Herrera's hand went to his medallion, fingers wrapping around the metal. "The people who took him—they trade down here. They move through spaces like this one, spaces your cameras can't reach, your warrants can't touch. You follow me in, you're not a detective anymore. You're a trespasser in a world that doesn't recognise your authority." The green lights pulsed. Somewhere deeper in the market, something that might have been music started up—a low, rhythmic thrumming that she felt in her sternum rather than heard with her ears. Harlow checked her watch. The leather strap was soaked, but the face was readable. The hands hadn't moved since she'd entered the corridor. She tapped the glass. Nothing. "What happens to the time down here?" "It doesn't. Not the same way." Herrera lowered his hands slowly, watching her face. "The Market exists in the gaps. Full moon's tomorrow night. After that, this location seals up and moves somewhere else. Could be anywhere in the city. Could be miles underground. You won't find it again without an invitation." "And you have one." "I have a token." He reached into his jacket pocket and produced something that made her stomach lurch—a fragment of bone, smooth and yellowed, strung on a leather cord. "Entry requires payment. The dead pay the toll so the living can trade." The vendors had stopped their murmuring. The entire market had gone quiet, dozens of faces turned toward her, waiting. The silver-haired woman tilted her head, studying Harlow with an expression that bordered on hunger. Herrera held out the bone token, its surface catching the bioluminescent glow. "You want to know what happened to Morris, this is the door. But you walk through it knowing there's no backup coming. No radio signal reaches here. No CCTV. No jurisdiction."
