The rain stopped before midnight, leaving Blackthorn Manor perfectly silent. Inspector Mara Venn arrived to find the gates standing open. A single lantern burned above the steps, staining them gold. Inside, the guests waited beneath portraits of forgotten, watchful ancestors. Lord Alder lay beside the hearth, one hand clutching violets. His dinner jacket was dry, though his shoes dripped seawater. The nearest ocean lay thirty miles beyond the frozen hills. Mara knelt and smelled bitter almonds beneath the cigar smoke. Behind her, someone locked the library door without a sound. Then every clock within Blackthorn Manor began striking thirteen together.
