The grandfather clock struck midnight, but nobody heard it chime. Detective Mara Ellis pushed open the mansion's heavy oak door. Rain dripped from her coat onto polished cold marble floors. Inside, the victim lay sprawled beside overturned mahogany chess table. Blood stained his white shirt, pooling around fallen black king. "Nobody touches anything until forensics arrives," Ellis muttered very sharply. Butler hovered nearby, hands trembling, eyes fixed on silent corpse. Window was open; curtains danced despite locked outside storm shutters.
