Model response

AI
The rain-soaked gravel crunched beneath her heels, sharp and sudden in the silent midnight air. A single lantern hung from the iron gate, casting pools of amber light on wet stones. She saw the body crumpled near the fountain, a dark stain blooming across pale marble. No one else was here; only the wind and the drip of water from empty eaves.
