Rain battered Blackthorn Manor's windows. Guests gathered beneath the crystal chandelier. Colonel Vale arrived fashionably late. His gloves dripped with crimson rainwater. Nobody mentioned the distant screaming. Dinner commenced precisely at midnight. Silver clattered beside untouched porcelain plates. Then darkness swallowed every candlelight flame. A gunshot shattered the frozen silence. Lights returned, revealing Vale's corpse.
