This film centers on an extremely wealthy man named "Cecil Sheridan Fox" (Rex Harrison) who is living in Venice and wants to play a joke on three attractive women: "Lone Star Sheridan" (Susan Hayward), "Princess Dominique" (Capucine) and "Merle McGill" (Edie Adams). So he sends them letters telling them he is dying and that he has a huge fortune to pass on to one of them--just to see how far each of them will go to prove their love for him. He enlists the aid of "William McFly" (Cliff Robertson) to assist him. But things don't exactly go according to plan. At any rate, rather than disclose any of the secrets that unfold I will just say that this film turns out to be both a comedy and a mystery. Now, while I thought both Cliff Robertson and Rex Harrison performed well enough, I must say that I especially liked Adolfo Celi as "Inspector Rizzi". I also didn't mind having such beautiful and talented actresses like the aforementioned Capucine, Susan Hayward and Edie Adams either. At any rate, this is an enjoyable comedy but be warned-there are a lot of twists and turns along the way.
