Rain battered the lonely mansion. Detective Black entered with caution. Candles flickered near the corpse. Blood pooled across ancient oak. Whispers echoed from hidden quarters. Shadows danced across peeling wallpaper. A note lay beside victim. Footsteps echoed down empty corridor. Someone watched through dusty window. Winter wind moaned through cracks.
