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.

Detective Harlow Quinn stepped out of the unmarked car, her boots crunching on the gravel of the abandoned Tube station beneath Camden. The air was thick with the scent of damp stone and something else, something metallic that clung to the back of her throat. She adjusted the collar of her coat, the fabric brushing against her sharp jawline, and glanced at the worn leather watch on her wrist. It was just past midnight, the witching hour, and the Veil Market was supposed to be long gone by now. "Quinn, over here," called a voice from the shadows. It was Detective Inspector Markham, a tall, wiry man with a penchant for conspiracy theories. He stood near the entrance to the platform, his silhouette outlined by the dim glow of a single overhead bulb. "Markham," she acknowledged, striding over with military precision. Her eyes, sharp and discerning, took in the scene. The platform was littered with debris—discarded crates, tattered tarps, and the remnants of what might have been a stall. But it was the body that drew her attention, lying sprawled near the edge of the tracks. "Victim's male, mid-thirties," Markham began, flipping through his notebook. "No ID on him, but the clothes suggest he was a vendor. Found this in his pocket." He handed her a small brass compass, its casing etched with protective sigils and a patina of verdigris. Quinn turned the compass over in her hand, noting the intricate craftsmanship. "A Veil Compass," she murmured, more to herself than to Markham. "Points to supernatural rifts." "Exactly," Markham said, his voice tinged with excitement. "I think he was trying to escape through a portal when something went wrong." Quinn crouched beside the body, her eyes narrowing as she examined the scene. The man's face was twisted in an expression of terror, his hands clutching at his throat. But there were no visible wounds, no signs of a struggle. Just the compass, and a bone token clutched in his other hand. "Doesn't add up," she muttered, more to herself than to Markham. "If he was trying to escape, why didn't he use the token? And why is the compass here, not pointing anywhere?" Markham shrugged, his gaze darting around the platform. "Maybe he was interrupted. Or maybe the portal closed before he could get through." Quinn shook her head, her mind racing. Something was off, something she couldn't quite put her finger on. She stood, scanning the platform with a practiced eye. The debris, the scattered remnants of the market, all seemed too... deliberate. As if someone had staged the scene. "Look at the tracks," she said suddenly, pointing. "No signs of recent activity. No footprints, no drag marks. If there was a struggle, it didn't happen here." Markham frowned, following her gaze. "You think he was moved?" "Possibly," Quinn replied, her voice thoughtful. "Or maybe he was never here at all." She turned her attention back to the body, her mind piecing together the puzzle. The compass, the token, the lack of evidence—it all pointed to something more than a simple escape gone wrong. But what? "There's something else," Markham said, breaking into her thoughts. "We found this near the entrance." He handed her a small, leather-bound book, its pages filled with cramped, spidery handwriting. Quinn flipped through the book, her eyes scanning the text. It was a journal, filled with notes on the Veil Market, its vendors, and its secrets. But one entry caught her attention, a single line scrawled in the margin: "The rift is unstable. Beware the shadows." "Shadows," she repeated, her mind racing. "What if he wasn't trying to escape? What if he was trying to warn someone?" Markham looked skeptical. "Warn them about what?" Quinn met his gaze, her expression grim. "About whatever's lurking in the shadows. Something that doesn't want to be found." She turned back to the body, her mind working through the possibilities. The compass, the token, the journal—it all pointed to something more than a simple accident. But what? "There's more to this," she said finally, her voice firm. "We need to find out who he was, what he knew. And we need to do it before the next full moon." Markham nodded, his expression serious. "I'll get the team on it. But Quinn, if you're right about this..." "I know," she replied, her voice steady. "But we can't let fear stop us. Not now." She turned away, her mind already racing with possibilities. The Veil Market, the rift, the shadows—it was all connected, she was sure of it. And she would find the truth, no matter what it took. As she walked back to the car, the compass clutched in her hand, she couldn't shake the feeling that she was being watched. But when she turned, there was nothing there. Just the shadows, shifting and whispering in the darkness.
