Cynara [1932] [DVD]

In Naples, the disgraced London barrister (Ronald Colman) is about to divorce his beloved wife Clemency (Kay Francis) and start anew in South Africa. But before parting she asks him to explain how the affair happened, which is done through a long flashback: When Francis goes to Venice with her sister, Colman meets a "shop girl" and has an affair. It appears that it is not platonic, and after all, this is 1932 England. Unfortunately, the woman he falls for is rather emotionally needy, and when the affair ends, she commits suicide. While Colman cannot be held legally responsible, at the inquest he is held morally responsible. After Colman and Francis separate, his friend who knew of the affair (and actually encouraged it), convinces Francis to think about what it would mean to her to never see him again...hinting at suicide. Francis surprises Colman by showing up on the boat to South Africa.
