Grady's apartment gets invaded by cockroaches just before Jessica arrives for a visit, but an old college friend of Grady's, Garrett Harper, who married hotel heiress Cornelia Montaigne, invites them to stay at the hotel. He even invites a girl Grady knew in high school, Sandra Clemens. However, incidents at the hotel cast doubt on Garrett's generosity as Sandra turns up dead and Garrett acts very suspiciously. With Grady once again the primary suspect, can Jessica extricate her nephew and find who really killed Sandra?
Grady returns again and gets framed for murder, which seems to happen to him all the time. He's so dopey that he doesn't realise that his college friend is using him. Well not until he overhears his friend paying some to frame him. It's a standard episode, has the usual tropes, but it's an ok episode. Plus it's nice to see Janet Leigh as one of the guest stars.
