This B movie is highly overrated. Joan Fontaine was the poor relation of Olivia DeHaviland and starred in mostly B pictures; this is one of them. We are supposed to believe a woman is going to kill a tall, good looking young man she is married to, so she can be the plaything of a rich member of society played by the relatively unattractive Herbert Marshall; a man in his fifties. Now, if the roles were reversed, you might have had a believable plot. Plenty of women married to older, unattractive wealthy men (and even poor unattractive older men) might be up for a little homicide. But to go in the opposite direction? Please. No one I ever met or heard about. The film is dated with its codes of honor and such, and really not worth viewing even for its frozen soap content, unless you are desperate for soap.
