Rain battered Blackthorn's shuttered windows. Inside, twelve guests waited uneasily. Colonel Vale raised his crystal. Then darkness swallowed the dining room. Someone screamed beside the fireplace. A gunshot shattered the silence. Lightning revealed Vale's fallen body. His crystal lay beside blood. Every guest watched every other. The bridge vanished beneath floodwater. Nobody could leave before dawn.
