Autumn has arrived at Castle Dark, and Nora Blake has settled into her role as an actor in Derek Corby's castle murder-mystery troupe. The setting of the fall mystery is the catacombs in the depths of the castle, and in this follow-up to Death in Castle Dark, the tombs become a place of terror when a man is murdered. Everyone around her is an actor—and therefore capable of convincing others of their innocence—Nora will have to go off-script to prevent a murderous encore.
