From The Perry Mason TV Show Book (Revised)
Betty Kaster is hired by Philip Stark to take care of Stark’s invalid wife, Frances, who has recently been injured in a car accident. Philip wants her in Mexico to recuperate. Supposedly a doctor has said it would be good for the sick woman’s lungs. But Betty suspects Philip is more concerned about Frances's recent $2 million inheritance than her lungs.

Betty knows Della from a lecture she gave at college and asks her for help, but she soon needs the Big Guy even more when Philip Stark is found murdered.

Perry believes Betty’s story about Philip’s illicit affair with bombshell Jill Fenwick. However, he focuses on the $2 million and the flock of vulture-relatives circling the Stark house.
