For some time now, Katherine Stewart has been visiting her husband Phillip every Wednesday in San Quentin prison who has been serving a year for involuntary manslaughter. He has been serving a term for killing his employer but for the last month, he has refused all visits from his wife. He is released on parole. Katherine consults Perry Mason and is at her wits end. She is now afraid that he will do something silly that sends him back to jail so she wants Perry to offer him a job on the east coast and get state approval for it. Jack Mallory, who contacts Katherine, is a private investigator looking into the theft of the valuable Jakarta diamond that disappeared at the same time Phillip Stewart was accused of his original crime. Phillip has managed to get his old job back with the firm Reed and Webber. Webber is buying out Mrs. Reed's part of the business and brought Phillip back to save the business which Reed nearly destroyed. When Mallory is found dead however, it's Phillip who is charged with murder and Perry defends him.
