The moonlit street lay silent. Rain pattered on cobblestone paths. Detective Hale gripped his flashlight. Shadows danced around ancient oaks. A scream shattered the night. Lights flickered in the mansion. He approached the creaking door. Inside, chaos greeted his eyes. A body slumped on rug. Blood pooled near crystal vase. Suspects whispered in dim corners. Clues waited to be found. Mystery hung thick like fog.
