Dr Sheila Carlin is good friends with Della who calls Perry in when she is being pestered by someone. On the theory that it could be somebody that she works with at a radio stations she arranges Perry to be interviewed by Winslow Keene who is also the station's owner. Winslow enrages the rest of the talk show hosts on the station by informing them of changes that he is making to their time slots. That night, Winslow is shot by a hit man hired by someone at the station and Sheila is set up for the murder. She calls in Perry and as usual Perry, Della and Ken swing into action to find out who really did it.
Unfortunately the movie Perry Mason: The Case of the Telltale Talk Show Host is not yet available on HBO Max.
