The rain stopped before midnight, leaving Blackthorn Hall in silence. Then a scream split the darkness above the eastern stairs. Detective Mara Venn found the drawing room door firmly locked. Behind it, someone breathed with the patience of a hunter. She raised her lantern, and the breathing ceased at once. A key turned inside, though all the keys hung downstairs. The door opened onto candlelight, blood, and a motionless figure. Lord Blackthorn lay beneath the window, still wearing his mask. His silver dagger pinned a white invitation to his chest. Across its face, fresh ink had carefully spelled Mara’s name. Outside, the clock struck thirteen as every candle slowly died.
