Model response

AI
A clock ticks in silence. Rain taps the window pane. The body lies face down. Blood pools on the rug. A single glove rests nearby. Candles burn on the mantle. Shadows crawl up the walls. The detective lights a cigar. Smoke curls toward the ceiling. Every chair stands in place. The knife is strangely missing. A faint perfume still lingers. Her lipstick was perfectly applied. He never arrived for dinner. A secret rests in stillness. Even the dust holds clues.
