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 should have been pitch black at half past eleven, but a sickly blue luminescence clung to the tunnel walls like algae. Detective Harlow Quinn descended the last of the rusted metal stairs, her torch beam cutting through the strange glow. The light shouldn't exist. Someone had reported flickering in the sealed tunnels, and when the first response team arrived, they'd found a body. "Detective." The uniform at the bottom nodded, his face pale. "It's... you'll want to see for yourself." She'd been told as much over the radio. What she hadn't been told was about the light, or the way the air tasted of copper and something else—something that made her teeth ache. Eva Kowalski stood twenty feet down the platform, her worn leather satchel discarded at her feet, round glasses catching the eerie glow as she crouched beside the victim. Quinn's jaw tightened. She'd specifically requested the scene be kept clean until her arrival. "Who authorized a civilian consultant?" Eva glanced up, tucking a strand of curly red hair behind her left ear. "Detective Inspector Morrison. He thought my expertise might be relevant." "Your expertise is ancient pottery, Dr. Kowalski." "Among other things." Eva straightened, revealing the body behind her. "This isn't pottery, but it's definitely ancient." The victim lay face-up on the platform, a young man in his twenties wearing a torn leather jacket. Three parallel lacerations crossed his chest, deep enough to expose bone. But it was the area around him that pulled Quinn's focus. Symbols, drawn in what looked like ash, formed a perfect circle around the corpse. They weren't gang tags or random graffiti. Each one had been rendered with precision, the kind that spoke of practice and purpose. Quinn knelt opposite Eva, careful not to disturb the circle. "What are they?" "Protective wards. Sumerian origin, though the arrangement is all wrong." Eva pointed to a cluster of marks near the victim's head. "These should form a barrier, keep something in—or out. But look here." Her finger traced the line without touching it. "This sequence is backwards. Whoever drew these opened something instead of closing it." The worn leather watch on Quinn's left wrist showed 23:47. The call had come in at 22:15, which meant the body had been here for at least ninety minutes, probably longer. She swept her torch across the platform. No blood trail. No signs of struggle. The victim's fingernails were clean, no defensive wounds on his hands or forearms. "He wasn't killed here." Eva shook her head. "The circle was drawn after he died. You can see where the blood hasn't spread into the ash. Someone placed him here, arranged him, then completed the ritual." "This isn't a ritual. It's a murder." "Can't it be both?" Quinn stood, playing her torch across the tunnel walls. The blue luminescence seemed brighter now, pulsing almost. She'd worked homicides for eighteen years. Domestics. Gang violence. The occasional serial. She understood rage, greed, fear—human motivations that left human evidence. This felt different. Wrong in a way that reminded her of three years ago, of Morris's final case, of finding his body in a condemned factory with marks that forensics couldn't explain. "What's wrong with the light?" Eva followed her gaze. "Residual energy. Whatever happened here, whatever they were trying to do with these symbols, it left an impression." "Energy doesn't glow." "This kind does." Quinn walked the perimeter of the platform, noting details. Empty crisp packets in the corner, dated from before the station's closure in 1956. Rust patterns on the rails unchanged in decades. But here, around the body, everything looked disturbed. The dust had been swept away in a ten-foot radius, leaving the concrete exposed. She crouched at the edge, running her finger along the clean line. Fresh. Recent enough that new dust hadn't accumulated. Something glinted near the wall. She retrieved it with gloved hands—a small brass compass, its casing covered in verdigris, its face etched with more symbols. The needle spun wildly, refusing to settle. "Dr. Kowalski." Eva joined her, and Quinn caught the sharp intake of breath. "Where did you find that?" "Does it matter?" "It's a Veil Compass. They're not exactly legal." Quinn turned it over in her palm. Protective sigils, Eva had called them. The same style as the ones around the body. "What does it do?" "Points toward supernatural rifts. Portals between..." Eva hesitated, pushing her round glasses up. "It's urban legend, mostly. Black market occult items that supposedly work." "Supposedly." "The needle shouldn't be moving like that unless—" Eva looked at the circle, at the backwards symbols, at the blue light pulsing along the walls. "Unless there's an actual rift nearby." Quinn's pulse hammered steady in her throat. She'd requested this case specifically after Morrison mentioned the location and the unusual circumstances. The Tube station. The sealed tunnels. It matched the pattern from Morris's investigation, the one he'd been pursuing when he died. He'd talked about hidden markets, about things moving through London that shouldn't exist. She'd thought he was having a breakdown from stress. "Is there a market down here? Underground trading?" Eva's freckled complexion went paler. "How do you—" "Answer the question." "The Veil Market moves locations. Every full moon. Sometimes they use abandoned stations, but I don't know how anyone would—" She stopped, her green eyes widening. "Tonight's the full moon." Quinn checked her watch again. 23:51. The victim's jacket had chalk dust on the shoulders, same texture as the symbols. His boots showed scrape marks consistent with being dragged. Someone had brought him here, killed him elsewhere, then used his body as part of something bigger. But what? And why here, why tonight? She stood, scanning the platform with fresh eyes. Not a crime scene. A workspace. The symbols weren't random—they formed a pattern, a purpose. The victim wasn't the point. He was a component. "If someone wanted to break into this market, what would they need?" Eva tucked her hair behind her ear again. "A bone token for entry. But you can't break in, not exactly. The wards are too strong. You'd need to..." She trailed off, looking at the backwards symbols. "You'd need to tear a hole in them. Force your way through." "Using these." "Using blood magic and a sacrifice, yes." The blue light flared brighter, and the compass needle locked suddenly northward, pointing down the tunnel into darkness. From somewhere deep in the station's abandoned passages came a sound like wind through a canyon, though the air here stood still. Quinn drew her torch up, catching movement at the tunnel's edge. Shadows that moved wrong, that stretched and bent against the light's direction. She'd seen something similar three years ago, right before Morris disappeared. "We're leaving. Now." Eva grabbed her satchel, stumbling backwards. "Someone actually did it. They opened a rift." "To where?" "To wherever things like that come from."
