Danger, Dr. Danfield aired from August 18, 1946 to April 13, 1947 and consisted of 26 episodes. It starred Michael Dunn as Dr. Danfield, an obnoxious unlicensed private investigator/criminal psychologist, and JoAnne Johnson as Rusty Fairfax, his secretary. The series, written by Ralph Wilkinson and produced by Wally Ramsey, was often criticized for its poor acting and writing. The show followed a formula where the crime was committed in the first third, solved in the second third, and then explained by Dr. Danfield to Rusty in the conclusion. The characters were generally one-dimensional, but the show remains enjoyable for light, casual listening.
