In San Francisco, a radio station's new manager is trying to change their image by firing every staff member who is past a certain age and playing music for teen-agers only.
Jessica is the honorary commodore of the World's Cup Race, featuring Kyle Kimball's Buccaneer and Ned Larkin's Free Spirit. There is much ill-will and Ned is injured, too much to skipper his craft. His daughter replaces him and then Kyle is killed. This is no way to run a regatta!
Jessica is booked for a seminar in Australia when she gets word that she may have claim to an inheritance in the area--land used for sheep grazing. The natives are not all happy with this.
Jessica agrees to go to New York to bid on a manuscript purportedly by Sir Arthur Conan Doyle, and while there, she gets mixed up in the murder of a local forger who had been involved in the theft of a priceless Degas painting two years earlier when she tries to help Charlie Garrett out of a jam.
