You are an expert fiction writer. Always keep the following rules in mind: - Write in past tense and use General English spelling, grammar, and colloquialisms/slang. - Write in active voice - Always follow the "show, don't tell" principle. - Avoid adverbs and cliches and overused/commonly used phrases. Aim for fresh and original descriptions. - Convey events and story through dialogue. - Mix short, punchy sentences with long, descriptive ones. Drop fill words to add variety. - Skip "he/she said said" dialogue tags and convey people's actions or face expressions through their speech - Avoid mushy dialog and descriptions, have dialogue always continue the action, never stall or add unnecessary fluff. Vary the descriptions to not repeat yourself. - Put dialogue on its own paragraph to separate scene and action. - Reduce indicators of uncertainty like "trying" or "maybe" When writing text: - NEVER conclude the scene on your own, follow the beat instructions very closely. - NEVER end with foreshadowing. - NEVER write further than what I prompt you with. - AVOID imagining possible endings, NEVER deviate from the instructions. - STOP EARLY if the continuation contains what was required in the instructions. You do not need to fill out the full amount of words possible.

The abandoned Tube station beneath Camden reeked of damp and old rust. Detective Harlow Quinn stepped over a puddle of black water, her boots splashing softly. The beam of her torch cut through the gloom, illuminating peeling posters on the walls, their edges curled like dead leaves. A bone token lay near the entrance, its surface smooth and cold. She crouched, picked it up, turned it over in her fingers. Not something you’d find in a standard London underground. A voice echoed from the shadows. “You’re late.” Harlow didn’t flinch. She knew that tone—dry, weary, but sharp as a scalpel. Eva Kowalski stepped into the light, her round glasses catching the torch’s glare. A worn leather satchel hung from her shoulder, stuffed with books that threatened to burst the seams. She tucked a curl of red hair behind her left ear, a habit Harlow had seen a hundred times before. “Traffic,” Harlow said. Eva smirked. “Since when does the Met let traffic stop you?” Harlow ignored the jab. Her gaze swept the platform. The scene was wrong. Too clean. No signs of struggle, no blood spatter, no discarded weapons. Just a single body, sprawled near the edge, arms outstretched like it had been placed there with care. A man in a dark overcoat, his face pale under the flickering torchlight. His eyes were open, staring at nothing. She knelt beside him. No wounds. No defensive marks on his hands. “Cause of death?” Eva shifted, her boots scuffing against the concrete. “That’s the thing. The coroner’s not sure. No poison, no trauma. Heart just... stopped.” Harlow’s fingers hovered over the man’s wrist, not touching. “Time?” “Roughly midnight. Witnesses say he was alive when he walked in here.” Harlow’s jaw tightened. Midnight. The Veil Market’s schedule moved with the full moon, and tonight was one. She stood, her torch beam sweeping the walls again. The bone token in her pocket felt heavier. “And the witnesses?” “Swore he came down here alone. No one followed. No one saw anything.” Harlow exhaled through her nose. “Bollocks.” Eva adjusted her glasses. “You think it’s connected?” “To what?” “The other cases. The ones that don’t make sense.” Harlow didn’t answer. She didn’t need to. Eva knew. They both did. Three years ago, DS Morris had walked into a similar scene—abandoned, no signs of struggle, no cause of death. The case had been closed as a heart attack, but Harlow had seen the look in Morris’s eyes the day before. Fear. Not the kind you got from a dodgy suspect, but the kind that settled in your bones. She moved further down the platform, her torch catching something metallic near the tracks. A small brass compass, its casing dull with verdigris. The face was etched with symbols she didn’t recognise—sigils, Eva would call them. The needle didn’t point north. It twitched, restless, as if searching for something just out of reach. Harlow picked it up. The weight was wrong. Too light, like it was hollow. Or like it wasn’t entirely there. “That’s new,” Eva said, stepping closer. Harlow turned it over. No maker’s mark. No engravings. Just the sigils, spiralling inward like a maze. “You know what this is?” Eva’s fingers twitched, like she wanted to snatch it. “A Veil Compass. Points to rifts. Portals. That kind of thing.” Harlow’s grip tightened. “And how do you know that?” Eva’s cheeks flushed, but she didn’t look away. “I’ve read about them. The Market trades in them.” “The Market.” Harlow’s voice was flat. The Veil Market. A place that wasn’t supposed to exist. A place where things were bought and sold that had no business being in this world. She’d heard the whispers, the rumours from informants who’d had one too many pints. But this was the first time she’d seen proof. She held the compass out. The needle spun wildly, then settled, pointing toward the far end of the platform. Toward a stretch of wall that looked no different from the rest—peeling paint, rust, grime. Eva followed her gaze. “It’s here. The Market. Or it was.” Harlow moved toward the wall, her torch beam steady. The air grew colder. Her breath fogged in front of her, though the station wasn’t that cold. She pressed her palm against the bricks. Solid. But the compass needle didn’t waver. “It’s not always visible,” Eva said, her voice quieter now. “The Market moves. It’s not... static.” Harlow’s fingers traced the mortar between the bricks. Nothing. No seams, no hidden doors. Just a wall. But the compass insisted. She stepped back, her military precision kicking in. Something was off. The body. The compass. The lack of evidence. She turned to Eva. “The witnesses. Did they mention anything... unusual?” Eva hesitated. “One of them said the man was talking to himself before he came down here. Said he was arguing with someone, but there was no one there.” Harlow’s pulse ticked up. “And the coroner’s report?” “Clean. No drugs, no alcohol. Just... nothing.” Harlow crouched beside the body again. The man’s overcoat was unbuttoned. She peeled it back. His shirt was pristine. No tears, no stains. But his left wrist bore a mark—a faint, red imprint, like a brand. A symbol. The same as the ones on the compass. Eva noticed it too. “That’s not—” “A sigil,” Harlow finished. She’d seen enough of them in Morris’s notes. Notes the Met had dismissed as the ramblings of a man losing his mind. She stood, her mind racing. The body. The compass. The sigil. The Market. It all fit. Too well. Morris had been chasing something similar before he died. Something supernatural. Something the Met refused to acknowledge. Eva was watching her, her green eyes sharp behind her glasses. “You think this is like Morris?” Harlow’s jaw clenched. She didn’t want to think it. But the evidence was there, staring her in the face. “The compass points to the Market. The Market was here. And this man...” She gestured to the body. “He didn’t just die. He was *taken*.” Eva’s breath hitched. “You think someone—or something—killed him?” Harlow didn’t answer. She didn’t need to. The pieces were falling into place. The lack of struggle. The lack of evidence. The sigil. The compass. The Market. It wasn’t a murder. It was a transaction. Or a sacrifice. She turned the compass over in her hand again. The needle still pointed at the wall. She took a step toward it. Then another. The cold intensified. Her torch flickered, as if something was draining the light. Eva grabbed her arm. “Harlow. Don’t.” Harlow shook her off. “We need to know.” “And if it’s still here? If it’s... open?” Harlow didn’t look back. She pressed her palm against the wall again. This time, the bricks gave way. Not like a door. Like a curtain. The torchlight revealed a sliver of space—dark, endless, humming with something that wasn’t sound but vibrated in her teeth. Eva’s grip tightened. “Harlow, for God’s sake—” A gust of wind rushed out from the gap, carrying the scent of ozone and something older, something that made Harlow’s skin prickle. The compass needle spun, then pointed inward, toward the darkness. She pulled her hand back. The wall sealed itself, as if it had never been open. The torchlight steadied. The cold retreated. Eva exhaled sharply. “Well. That’s... new.” Harlow stared at the wall. The compass still pointed at it, insistent. She pocketed it, her mind racing. The Market had been here. The man had gone in. And whatever was on the other side had taken him. She turned to Eva. “We’re missing something.” Eva crossed her arms. “Like what?” Harlow’s gaze dropped to the body again. The sigil on his wrist. The compass in her pocket. The bone token she’d found at the entrance. “A pattern. Morris had one of these.” She tapped her pocket. “In his notes. He’d been looking into the Market. And then he died.” Eva’s face paled. “You think he found it? The Market?” Harlow’s voice was steel. “I think he found something. And I think it killed him.” A silence settled between them, thick with the weight of what they both knew. The Met wouldn’t touch this. Not without proof. And proof was the one thing that kept slipping through their fingers. Eva adjusted her glasses, her nervous habit forgotten for once. “So what do we do?” Harlow looked at the compass in her hand, then at the wall. The Market moved every full moon. Tonight was a full moon. And the compass was pointing at a wall that had just let them see behind the curtain. She met Eva’s gaze. “We follow the needle.”
