Model response

The rain fell without mercy. Detective Mills arrived at midnight. The body lay face down. Blood soaked the marble floor. Nobody had heard any screaming. The window stood wide open. Cold air filled the room. Mills knelt beside the victim. Her face showed pure terror. Someone knew she was alone. Footprints led toward the garden. The killer had been careful. Mills pulled out his notebook. This case would not rest.
