The story concerns a witch replacing her twin sister as queen of a city state, which brings her into conflict with Conan who had been the captain of the queen's guard. Themes of paranoia, and the duality of the twin sisters, are paramount in this story but it also includes elements of the conflict between barbarism and civilization that is common to the entire Conan series. The novella as a whole is considered an average example of the series but one scene stands out. Conan's crucifixion early in the story in the second chapter ("The Tree of Death") is considered one of the most memorable scenes in the entire series. A variation of this scene was included in the 1982 film Conan the Barbarian with Arnold Schwarzenegger.
