Danger, Dr. Danfield is a detective melodrama that features the story of Dr. Daniel Danfield, an obnoxious, unlicensed private investigator and criminal psychologist. The show follows a formula, with crimes being committed in the first third of the program, Dr. Danfield solving them in the second third, and then explaining the solution to someone (usually his secretary, Rusty Fairfax) in the conclusion. The show is most similar to Nick Carter, Master Detective; Casey, Crime Photographer; and The Falcon but leans more towards a lighter and less demanding approach in terms of emotions and intellect, making it suitable for drive-time or casual listening.
The show aired 26 episodes, beginning on August 18, 1946, and running through April 13, 1947, on the ABC network. All episodes are available and starred Michael Dunn as Dr. Danfield, alongside JoAnne Johnson as Rusty Fairfax. Danger, Dr. Danfield was written by Ralph Wilkinson and produced by Wally Ramsey. Despite featuring some of the worst acting and writing of any detective show, the show was syndicated for several years after its original run.
