The Searching Wind(1946)

Always the diplomat, Alex Hazen is slow to take sides in Europe of the 1920s and 1930s. Cassie Bowman wants him to be more decisive and leaves him in Rome just as Mussolini is coming to power. There Alex marries Emily, daughter of a newspaper publisher who hires Cassie for his Paris bureau -- just before retiring from active management of his paper. Alex and Emily's son Sam, recently returned from active duty in World War II, learns the whole story one night in Washington when Emily invites Cassie to dinner. Sam has a story to tell, too.
