Model response

The old clock struck midnight. Shadows stretched across the floor. A faint scent of ozone. Detective Harding pushed the door. Lord Harrington lay quite still. His pearl tie was askew. Dark blood stained the carpet. Something felt terribly wrong now. A single shard of glass. No light reflected within it. Who would do such a thing? The silence offered zero clues.
