Model response

The rain fell heavily tonight. Detective Marsh arrived at midnight. The mansion loomed impossibly dark. Someone had died that night. Blood stained the marble floor. A glass lay shattered nearby. No one heard any screams. The butler stood very still. His white gloves held secrets. Marsh knelt beside the body. She had been quite young. Her eyes stared at nothing. A red rose rested nearby. Someone had left it deliberately. Marsh noted every cold detail. The killer was still here.
