From The Perry Mason TV Show Book
Only the rich could have the problems that trouble the Benson family. Daddy is dead, and Matilda Benson rules her children with an iron fist and the promises in her will. Imagine the shock Matilda suffers when her little brood gets involved in a potential gambling scandal and later the unspeakable—murder!
Matilda hires Perry and he finds this a tough case. Watch for Ellen Corby (Granma on The Waltons) as a gambler.
