Rain tapped on stained glass. Cold wind shook the door. Arthur entered the quiet parlor. A sharp metallic odor lingered. He saw the leather armchair. Lord Sterling sat there motionless. Red blood stained his collar. A silver dagger lay nearby. The antique clock ticked loudly. Footsteps echoed down the hall. Arthur reached for his revolver. Someone watched from the shadows.
