This fourth series sees our arty, adulterous Bohemians struggling with the issues of class, money and how to become truly modern. Henry is concerned about Vera's dangerous susceptibility to romance, and her tendency to fascinate several women at once. In addition, he is wrestling with his biography of the king, misses the hurly burly of life at the Foreign Office and is tempted to stand for Parliament as a Labour MP. Meanwhile, Vera tangles with a randy Llewd George, accompanies Ginny to Sandwich where they meet Lytton Scratchy and Dora Barrington, and takes part in an indiscreet radio broadcast and a surprising séance. The friends also embark on a trip to Venice, where they meet Dave Lollipop, his pneumatic German wife Frieda and man-eating American art connoisseur Peggy Googleheim.
