Nick and Nora Charles (William Powell and Myrna Loy) are back for their third film in this series, and sporting a new addition to the family (Nick Jr.) Family business with one of Nora's father's associates leads them to a Long Island estate, where the bodies and suspects appear even before they arrive at their destination. Before long, the body count rises and the suspects take on an international flavor (in the form of a very young Sheldon Leonard, who later gained fame as the producer of "The Dick Van Dyke Show" and "I Spy"). Between cocktails, flirting and playful banter between the co-stars, the movie reaches a suspenseful end as Nick put the clues together and reconstructs the crime, probing the minds of those present until the murder cracks. Between your own cracking up (with laughter), you'll be guessing who done it to who in this well-constructed mystery-romantic comedy.
