Entre esposa y secretaria

A lot of this is typical 1930s melodrama. The story continues because various of the characters fail to have the obvious conversations, which would have cleared things up in a jiffy.

The scene I found particularly interesting and innovative was the penultimate one. In the third from the end scene, Harlow shows up in Loy's stateroom aboard the French Liner ship she is planning to take to Europe to forget about her husband (Gable), whom she imagines, incorrectly, to have had a fling with his secretary Harlow during a business trip to Havana. Harlow tells Loy that if she leaves Gable now, he will turn to Harlow out of loneliness and Loy will never get him back. (Yes, that sounds like the mother's speech to Norma Shearer in The Women.) Loy believes, incorrectly, that she has already lost Gable, so she says she won't go back to him. Harlow tells her that that would make her (Harlow) happy.

The next scene takes place in Gable's office. He is talking with Harlow. We hear footsteps coming down the hall outside. Footsteps that take a long time. It turns out that they belong to the cleaning lady. Then, when she leaves, we hear footsteps again, very assertive footsteps, for a long time. Harlow gets up - she suspects it is Loy, come to return to her husband. And this time it is. Harlow then walks through the next, large office - more long footsteps - and leaves. The use of the footsteps is really very impressive.
