Mr. District Attorney is a popular radio crime drama which aired on NBC and ABC from April 3, 1939 to June 13, 1952. The series focused on a crusading D.A., initially known only as "Mister District Attorney," or "Chief", and was later translated to television. On television the D.A. had a name, Paul Garrett, and the radio version picked up this name in the final years when David Brian played the role. A key figure in the dramas was the D.A.'s secretary, Edith Miller.

An assistant district attorney gets mixed-up with a woman who is working for the group that he is investigating.

An assistant prosecutor and his spunky friend investigate a suddenly hot case.

Like the first entry, this one is played mostly for laughs, with Radio's Mister District Attorney. James Ellison replacing Dennis O'Keefe as feckless assistant DA P. Cadwallader Jones. The publisher of a tony fashion magazine is murdered, requiring Jones to sift through a colorful array of suspects. He is helped along by snoopy girl reporter Terry Parker.
