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 stood at the edge of the derelict Tube station, her breath condensing in the cold subterranean air. The distorted echoes of dripping water amplified the silence. She glanced at her watch, its worn leather strap familiar and reassuring, before scanning the scene. Legends about this abandoned Camden station swirled with dark myths; now it housed an even darker reality. The call had come at the break of dawn. A body had been found within the labyrinthian expanse of the old station, the entrance to The Veil Market. Quinn had arrived to find forensic teams already at work, their torches slicing through the gloom, highlighting the morbid tableau. “A grim locale for a murder,” said Eva Kowalski, adjusting her round glasses and tucking a curl of red hair behind her ear. She stood clutching her leather satchel, the familiar shape laden with books. Eva's green eyes held a mix of intrigue and unease. “Evie, what are you doing here?” Quinn asked, scrutinizing the awkward position of the victim's body, propped against a mossy wall. He wore a crisp suit, incompatible with the filth of his surroundings. “The Museum sent me. The Veil Market's ancient history, restricted archives... figured I might be useful.” Eva's freckles blended with the darkness, a hint of academic fervor in her voice. Quinn huffed slightly—a sound almost resembling a chuckle. “Always where the action is.” She crouched beside the body, her fingers deftly moving to examine the wound. A jagged tear marred the man's chest, yet no blood pooled around him. A clean crime scene suggests a body moved, an uncomfortable thought in itself. “Heart attack,” Eva mused, her voice breaking the eerie silence. “Or natural causes, no sign of struggle.” “Too easy,” Quinn whispered, her eyes narrowing at the puncture mark along the victim’s inner arm. She gestured toward it. “Looks like he was injected with something. Get a close-up of that, Sam.” The forensic photographer nodded, the shutter of his camera capturing what words could not. Quinn stood, taking in the scene, calculating silently. The unnatural stillness hung heavy. A chill slipped between Quinn's collar and neck. “It was staged,” Quinn finally said, more to herself than to Eva. Eva frowned, a hint of curiosity stealing over her determination. “What makes you say that?" Quinn pointed at the ground near the body's feet. “Dust patterns. They’re too... perfect. No signs of disturbance. Someone wanted us to find him like this.” A stifled murmur emanated from the shadows. Quinn turned sharply, eyes finding a young officer nervously flicking through his notes. “Something to add, constable?” “Well, there’s this, ma’am,” he said, holding up a small brass compass, verdigris dulled in the muted glow of the headlights. “Found this close by.” Eva’s eyes lit up. “A Veil Compass. It points towards supernatural rifts.” Quinn turned it over in her hands, the etchings of protective sigils catching the meagre light. “Not something you’d expect to find on a banker,” she murmured, noting the symbols burned into the back. Symbols she'd seen during cases that fought constantly against slipping into the inexplicable. “Means he had business within The Veil Market. Possibly more,” Eva added, her voice pitched with a sense of discovery. Quinn frowned, something uncomfortable gnawing at her thoughts. “If he had this, he wasn’t just wandering lost. He was here for a reason.” Eva nudged one of the discarded items on the ground with her toe—a bone token, commonly used for entry into the Veil Market. "He had access," she murmured. “Did he use it himself or did someone place it?” Quinn wondered aloud. “Check for others like this. This scene smells wrong.” “I... I think I saw something,” offered the constable, glancing down the tunnel, his nervous habit betraying an unspoken discomfort. “Lead on,” Quinn commanded, torchlight bouncing off the grimy walls as they moved deeper. They stepped over a rusty rail and entered a chamber lined with flickering torches. The air smelt of old books and stale alchemy. The gap that once held bustling supernatural haggling now lay silent apart from the shuffle of their footsteps. Quinn noticed shattered glass on the floor, glinting in their lights like tiny mirrors. “Something heavy smashed here. Recent too.” Eva nodded, pulling reference books from her satchel and frantically flipping through pages. “Could be related to the alchemical substances they sell. Volatile stuff, very restricted.” “And yet, look here,” Quinn said, crouching to pick up faded pamphlets and a broken vial. “An empty potion bottle. That doesn't seem important.” Eva squinted. “It could be a binding potion. Whoever’s involved may have tried using it, with unpredictable outcomes.” The constable suddenly stopped, flashlight revealing cleaned stones free of dust and moss. “Someone's been here, recently.” "More than one," Quinn muttered, narrowing her eyes. The vision of foot tracks crisscrossing overly-clean patches put her mind into overdrive. The evidence didn’t fit together neatly like it should have. “Ma’am,” someone called, running toward them with a piece of cloth in hand. He handed it to Quinn, a small, delicate item embroidered with unfamiliar symbols. Eva’s breath hitched. “That’s... that’s ancient Sumerian,” she whispered. “An incantation for banishment. Old magic.” Quinn’s eyes moved rapidly, scanning the surroundings—and then she saw it. A subtle door in the back wall, partially concealed by shadow. "We need this opened." Her tone brooked no argument. Two officers methodically worked the hidden latch, and the stone door creaked open. The small chamber behind it revealed a low-lit sanctum. Candles flickered, their live flames punctuating the oppressive quiet. At the center was an intricate, drawn sigil on the floor, still fresh as if hurriedly completed. Eva gasped again, voice trembling. "That's... a summoning circle. Whoever they tried to summon, they might have succeeded. And it wasn't meant for them." Quinn's expression darkened, the pieces falling into place with chilling clarity. "Whoever killed him disrupted something far darker. They're hiding what truly went wrong here." Eva nodded, gripping her satchel tighter. "And they knew enough to send him as a scapegoat." Silent acknowledgment passed between them, an understanding of the dangerous web they had unwittingly brushed against. With grim determination, Quinn stood, her bearing still sharply military. “Evie, get these symbols documented. We need to cross-reference everything.” Eva obliged as Quinn turned to the young officer, her eyes locking onto his. “Secure the area. We’ve only scratched the surface.” In the dim recesses of the old Tube station, Detective Harlow Quinn felt the shadow of something larger encroaching, a darkness hidden beneath the surface. The evidence didn’t line up, but she knew the truth hid in plain sight. The station's dread remained thick, crawling through the lantern-lit air, telling stories unseen yet felt by those daring enough to seek them. Harlow’s instincts pricked: the case of her late partner DS Morris hung close, with truths tied somehow to this paranormal undercurrent. But that would unravel later, when shadows conversed in blacker nights. “Everyone, be on guard,” Quinn ordered, the words punctuating the twisted mystery expanding beneath London's streets.
