Rain hammered glass as Detective Mara Vale entered Blackthorn Manor. The butler with hollow eyes showed her the dining room. Lord Blackthorn sat slumped at the head of the table. A silver knife protruded from his chest, glistening under candlelight. The guests stood frozen near the fireplace, whispering uneasy accusations. Mara knelt beside the body and studied the crimson wound. The old clock above the mantel stopped at exactly midnight. No footprints marked the carpet, no forced entry, no motive. Someone in this room truly knew exactly how he died. Mara looked up and asked, "Which one of you lied?"
