Midnight thunder rattled old windows. Shadows danced across marble floors. Scream shattered heavy midnight silence. Detective Gray approached flickering chandelier. Lifeless body lay beside staircase. Blood pooled into dark crimson. Guests trembled behind locked drawing-room. Secrets hid under ancient floorboards. Gray knelt examining ominous footprints. Night swallowed every whispered clue.
