Bulldog Drummond is a radio crime drama in the United States. It was broadcast on Mutual April 13, 1941 – March 28, 1954. Garyn G. Roberts wrote in his book, Dick Tracy and American Culture: Morality and Mythology, Text and Context, "With its trademark foghorn, Bulldog Drummond was one of the premier mystery programs of its time."
Bulldog Drummond was "a British investigator called 'Bulldog' because he was relentless in the pursuit of criminals." The character was created by British author H. C. McNeile. In addition to McNeile's books, Drummond was featured in a series of films from Paramount Pictures in the 1930s. Drummond was described as "a polished man-about-town, whose hobby is crime detection and the apprehension of criminals."
