System

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.

Write a fully fleshed out scene of at least 1000 words in the mystery genre.

A detective arrives at a crime scene in an unusual location. Something is wrong — the evidence doesn't add up. A colleague is present, offering a different interpretation. Through careful observation and deduction, the detective begins to see what others have missed.

Use the codex entries above as your world reference for characters and setting.
Only include the prose of the scene without any markdown or commentary.

Model response

The abandoned Tube station smelled of rust and damp concrete, a musty undercurrent beneath the sharper scent of blood. Detective Harlow Quinn crouched beside the body, her salt-and-pepper hair catching the harsh beam of her flashlight. The victim—male, mid-thirties—lay sprawled between two rusted tracks, his limbs arranged with an unnatural precision that made the hairs on the back of her neck stand up.

She adjusted the worn leather watch on her left wrist, a nervous habit born of eighteen years on the force. Something here didn't track. The wound pattern suggested a ritualistic killing, but the blood spatter told a different story. Too controlled. Too deliberate.

"Forensics is still processing the scene," said Detective Roberts, hovering at the edge of her periphery. "Looks like a standard underground murder. Probably a drug deal gone wrong."

Quinn's sharp jaw tightened. She'd heard that dismissive tone before. Her fingers traced the edges of the victim's jacket, noting the unusual fabric—not standard street wear. Silk threads with an iridescent sheen caught the light, whispering of something more complex.

A small brass object glinted near the victim's right hand. Quinn carefully extracted an evidence bag from her coat, sliding the item inside. A compass, its face etched with intricate sigils. The needle trembled, not pointing north but quivering like a live thing.

Memories of her partner, DS Morris, flickered at the edge of her consciousness. Three years gone, and still these strange cases haunted her. Supernatural origins lurking just beyond rational explanation.

"This isn't a simple murder," Quinn said, her voice cutting through Roberts' idle chatter. "Look at the precision of the wound. The positioning. This was a message."

Roberts scoffed. "A message? It's a body in an abandoned Tube station. Sometimes a murder is just a murder."

Quinn's brown eyes narrowed. She'd heard that dismissive tone before—right before cases spiraled into something far more complex than anyone anticipated.

The compass in her evidence bag continued to tremble, its needle dancing to a rhythm only it could hear.
