Bob Becker P.I. is Jim Scott Books #22, and introduces Bob Becker and a few other new characters. Bob is Private Investigator, who owns and operates his small company, Bob Becker Decretive/Protection Agency, with his partner Bill Hedden in St. Charles County, Missouri, just across the Missouri River from St. Louis County. After a woman living in Los Angeles sees her husband kill a woman, she flees to the St. Louis area, arriving at Bob's office, just as two of the men working for her husband attempt to kill her.
From that point onward, Bob agrees to protect her, until her husband can be brought to justice. Along the way, he has help from Hector Garcia, who dispatches two of his men to assist him in his efforts, along with the use of Jim Scott's computer, as well as Dan and Janet Orf. Needless to say, he succeeds.
