When Kitty is 25, in a panic, she marries Walter Fane and moves to Hong Kong, where he's a bacteriologist who works for the government. When Walter discovers she's having an affair, he gives Kitty a choice: if her lover will divorce his wife and marry Kitty, Walter will give Kitty a divorce. Otherwise, Kitty must follow him to an area in China which lost its only doctor to cholera, and where cholera is still raging. Heartbroken when her lover won't leave his wife, Kitty goes into the heartland of China with Walter. The story finally takes off and Kitty begins to show some character.
