The House of the Four Winds
John Buchan, 1st Baron Tweedsmuir
 At the beginning of the novel several characters formerly seen in Huntingtower and Castle Gay are about to go to Europe for the summer, for a number of different reasons: Mr McCunn going to a German Kurhaus for his health, Alison to join her parents in the Tirol, the Roylances to attend a dull conference in Geneva, Jaikie on a walking tour, Dougal on a mission for his newspaper. Jaikie meets Randal Glynde who encourages him to visit Evallonia, which is on the verge of a revolution, and arranges for him to meet Prince Odalchini at his castle, "The House of the Four Winds". On the way he meets Ashie, a friend from Cambridge who is now a leader of the third element in the Evallonian political scene, Juventus, a cross between a youth group and a national revival movement. The Juventus people, like the Monarchists, want to overthrow the corrupt and unpopular government, but see young Prince John as a puppet of the conservatives, "the old gang". Jaikie eventually agrees to act as a secret liaison between the two groups. Meanwhile Alison and the Roylances have rescued Prince John from Mastrovin. They bring him into Evallonia in disguise. Dickson McCunn, informed of the situation by Dougal and feeling obliged by his promise to Prince John to lend a hand, joins the Monarchists and proposes a shrewd scheme for inducing Juventus to back Prince John. Mishaps and the machinations of Mastrovin lead to dangerous complications before the prince attains the throne.
