In The Power-House, Leithen's quiet life is disrupted when he is pitted against the murderous forces of an international network of anarchists, and its chilling leader. Then, adopting the nom de guerre of "John Macnab," Leithen and two friends risk their reputations when they take to poaching in the Highlands of Scotland in an effort to recover their zest for life. Finally, in The Dancing Floor, Sir Edward befriends a young man haunted by an annually recurring dream, and a young woman stubbornly determined to atone for the sins of her disreputable family, even at the risk of her own life.
