To complete the previous comment (which I agree), I will add that Michel Simon's (clever) machiavelism is to visit the lawyer PRIOR the killing of his wife(pretending he already did it),in order to know how to commit the "perfect" murder without being sentenced as much as possible; smart!
Maybe Sacha Guitry's most cynical movie about marriage. The famous Director/writer was an active womanizer and we may think that he was deceived by the female gender at this time (close to his death)and wished some revenge through this film (his young last wife -Lana Marconi- was supposedly interested in his money only and eventually sold his late husband's house in Paris to speculating promoters, only a couple of years after his death (the house was destroyed immediately to build a new building of no interest, whereas Guitry's last deep wish was to open a comedian's museum to exhibit his rarest manuscripts, costumes, theater memorabilia, etc.). What a pity!
