Model response

The body lay there still. Rain hammered the old dock. Detective Marsh arrived at midnight. Her flashlight cut the fog. A man floated face down. His coat was soaked through. Nobody had called it in. A dog had found him. Marsh knelt beside the water. His hands showed no wounds. Something felt deeply, horribly wrong. A rose sat nearby, fresh. She bagged it with care. Her partner radioed for backup. The dock creaked behind her.
