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 echoed with a stillness that felt unnatural. Detective Harlow Quinn crouched beside the chalk outline, her sharp jaw set in concentration. Fluorescent crime scene lights cast harsh shadows across the grimy platform, illuminating details most would miss.

Her worn leather watch caught the light as she shifted, fingers tracing the edge of a peculiar scorch mark near the victim's outlined shape. Not burn marks, exactly. More like a residue of something... else.

"Forensics is calling it a standard mugging gone wrong," Eva Kowalski said, her round glasses sliding down her nose as she consulted a leather-bound notebook. Her curly red hair was pulled back, freckled hands gripping a pen with nervous intensity.

Quinn's brown eyes narrowed. "No. Look closer."

The scorch marks formed a deliberate pattern. Geometric. Intentional. Not random violence, but something ritualistic. Her military precision training demanded logic, pattern, explanation. And this scene offered none of those comfortable assurances.

"The pattern," Quinn murmured, more to herself than to Eva. "These aren't random."

Eva tucked a stray curl behind her left ear, a telltale sign of her rising anxiety. "You think this is... something else? Something not in the standard report?"

Quinn stood, her 5'9" frame casting a long shadow across the platform. Eighteen years on the force had taught her to trust her instincts, especially after Morris's unexplained death three years ago. That case had shown her how thin the veil between normal and supernatural could be.

"We're missing something," she said. "Something fundamental."
