It was a stormy night. Lightning flared across the sky. Footsteps echoed down empty hall. Detective Harper arrived carrying briefcase. Bloodstains spread on antique carpet. A whisper slithered from curtains. Victim’s lifeless eyes stared upward. Rain tapped softly on window. Someone gasped behind closed door. Footsteps retreated into looming shadows.
