You are an expert novelist with a gift for vivid, immersive prose. You write in tight third-person limited point of view with a strong narrative voice. Your prose is clean, precise, and engaging — you favor strong verbs, concrete details, and natural-sounding dialogue. You will be given a story bible (codex) containing canonical details about characters, locations, items, and lore. Use these details to ground your writing in the established world. Stay consistent with the codex. Write only the prose of the scene. Do not include titles, chapter headings, markdown formatting, or any commentary before or after the scene.

The rain came down in sheets, turning the London pavement into a slick mirror of neon and shadow. Detective Harlow Quinn pressed her shoulder against the brick corner of a shuttered newsagent's, her breath coming slow and measured despite the cold that seeped through her coat. Three weeks of legwork had brought her to this street in Camden, and she wasn't about to let the weather wash away her best lead in months. She checked the worn leather
watch
on her left wrist. Eleven forty-three. The suspect had entered the dilapidated building across the road eleven minutes ago—a structure that city records insisted had
been condemned
after a fire in 2019. Yet the man she'd followed from Soho had slipped through a door that looked recently oiled, moving with the confidence of someone who knew exactly where he
was going
. Tomás Herrera. Twenty-nine. Former paramedic who'd lost his license under murky circumstances involving "unauthorized treatments." Quinn had tracked him from The Raven's Nest, that dim bar with its distinctive green neon sign where the city's strangest cases
seemed to
originate. She'd
watch
ed him through the rain-streaked window, nursing a whiskey she hadn't touched, noting how others in the bar had given him space. Respect, maybe. Or fear. The door across the street opened. Quinn flattened herself against the wall as Herrera emerged, pulling his jacket tighter against the downpour. He looked different than he had in the grainy photos she'd pulled—harder, maybe, the olive skin of his face drawn tight over high cheekbones. The Saint Christopher medallion around his neck caught the light from a passing car,
glinting
once before disappearing beneath his collar. He glanced left, then right, his warm brown eyes scanning the street with an alertness that told Quinn he
was expecting
trouble. Good instinct. She was trouble. He set off at a brisk walk, not quite running but moving with purpose. Quinn gave him a ten-second head start before pushing off from the wall and following. Her shoes squelched in puddles she couldn't avoid, but the rain was loud enough to cover her
footsteps
. Forty-one years old, and she was still doing foot chases through London at midnight. DS Morris would have laughed at her. Would have been beside her, matching her stride for stride, making some crack about her questionable taste in hobbies. Morris wasn't beside her anymore. Three years since that night, and she still couldn't look at a closed case file without her chest tightening. Herrera turned down a side alley, and Quinn picked up her pace. The buildings here were older, Victorian brick darkened by decades of soot and neglect. Graffiti tagged the lower walls, colorful swirls that meant nothing to her. Somewhere above, a window was open, jazz music spilling out into the rain. She reached the corner and peered around it. Herrera was still visible, his dark curly hair plastered to his skull, moving toward what looked like a Tube entrance. But that was wrong—she knew this area,
knew that the
nearest station was three blocks east. This entrance shouldn't exist. Yet there it was: a stairwell descending into the earth, half-hidden behind an overflowing skip. The faded roundel above the stairs was barely visible, painted over so many times that only the shape remained. Herrera didn't hesitate. He descended into the darkness without looking back. Quinn's jaw tightened. She thought about calling for backup, dismissed the thought almost immediately. What would she say? That she'd followed a disgraced paramedic into a Tube station that wasn't on any map? That she
was investigating
a group of people connected to cases the Met had quietly buried? Her superintendent already thought she was one bad day from forced leave. She wasn't about to give him ammunition. She started down the stairs. The change was immediate. The rain's roar faded to a distant whisper, replaced by a damp silence that felt heavy,
oppressive
. The air smelled different down here—older, somehow, with a metallic undertone that reminded her of the blood bank her grandmother had visited in her final years. Quinn rested her hand on the wall to steady herself, feeling moisture that was too thick to be simple condensation. The stairs spiraled downward longer than they should have. She counted the steps, a habit from her military days, and stopped at seventy-three when her foot found level ground. A tunnel stretched before her, lit by bulbs that hung from wires like crooked teeth. The walls
were lined
with tile that might once have been white but had yellowed to the color of old bone. She could hear
footsteps
ahead, receding. Herrera was still moving. Quinn pressed forward, keeping her breathing quiet. The tunnel opened into what must have once been a platform—a proper Tube station, complete with faded advertisements for shows that had closed decades ago. But the space had
been transformed
. Tents and stalls lined the platform, their canvas walls glowing with lamplight from within. Vendors called out in languages she didn't recognize, their voices merging into a low hum that
echoed
off the vaulted ceiling. She had found something. Something big. Quinn stayed in the shadows at the platform's edge,
watch
ing. A woman passed within arm's reach, her basket filled with glass vials that pulsed with faint light. Beyond her, an elderly man
was negotiating
over something that looked disturbingly like a human hand—until Quinn blinked and realized it
was made
of copper, articulated joints
gleaming
in the lamplight. Everywhere she looked, she saw goods that defied easy categorization: books whose pages turned themselves, jewelry that floated above
velvet
cushions, bottles labeled in handwriting that
seemed to
shift even as she
tried to
read it. The Veil Market. She'd heard the name in whispers during her investigation, always from informants who refused to elaborate, who looked at her with something like pity before clamming up entirely. A black market for things that shouldn't exist. She'd dismissed it as urban legend, another layer of the supernatural nonsense that had infected her case files since Morris died. Standing here now, she felt the familiar
weight
of that night pressing against her chest. The things she'd seen. The things she'd refused to believe. A burst of laughter drew her attention to the left. Herrera had reached one of the larger stalls at the far end of the platform, where a heavyset man with a shaved head
was gesturing
expansively. Even from this distance, Quinn could see the tension in Herrera's shoulders. Whatever they
were discussing
, it wasn't friendly. She took a step forward—and stopped. At the entrance to the platform, partially hidden by a torn poster advertising the Queen's Silver Jubilee, was a small table. An old woman sat behind it, her face a map of wrinkles, her eyes milky with cataracts. In front of her was a wooden box filled with what looked like carved bones, each one stamped with a symbol Quinn didn't recognize. A man approached the table and placed a coin in the woman's palm. She handed him a bone token in return. He tucked it into his palm and walked past her, onto the platform, without a second glance. Entry requirement. The realization settled into Quinn's stomach like a stone. She didn't have a token. She didn't know what the token cost, or where to get one, or what the consequences might be for walking onto that platform without permission. She could turn back. Return to the surface, document everything she'd seen,
try to
build a case that wouldn't get her laughed out of the building. That was the smart play. The safe play. But Herrera was still at that stall, still arguing, and somewhere in this impossible place was the answer to what had
happened to
Morris. She could feel it in the sharp ache behind her eyes, the same sensation that had haunted her for three years whenever she got close to something that mattered. The old woman turned her head, and Quinn froze. Those clouded eyes couldn't possibly see her—couldn't possibly track her movement in the shadows—and yet they did. The woman smiled, revealing teeth that were too sharp, too numerous. "Detective," she said, her voice carrying across the distance with unnatural clarity. "You've come a long way in the rain. Are you staying?" Quinn's hand moved instinctively to her hip, to the comfort of her service weapon. She didn't draw it—wouldn't, not yet—but the gesture steadied her. Eighteen years on the force. Military service before that. She'd faced terrorists, rioters, a man with a knife who'd been high on something that made him strong enough to throw her through a window. She'd survived all of it. "I'm staying," she said. The old woman's smile widened. She reached into her box and withdrew a bone token, holding it out between two fingers. "First one's free," she said. "The second will cost you more than money." Quinn approached the table
slowly
, keeping her movements deliberate and visible. She took the token. It was warm against her palm, warmer than it should have been, and the symbol stamped into its surface
seemed to
writhe at the edge of her vision. "Welcome to the Veil Market, Detective Quinn. Try not to break anything you can't pay for." She should have asked how the woman knew her name. Should have demanded answers, pulled rank, done something other than walk onto that platform with her heart hammering against her ribs and Morris's ghost at her shoulder. But Herrera was still ahead, still within reach, and Quinn had never known when to leave well enough alone. She stepped into the market, and the crowd closed around her like water.
