The New Adventures of Sherlock Holmes is a radio drama series which aired in the USA from 1939 to 1950,[1] it ran for 374 episodes, with many of the later episodes considered lost media.[2] The series was based on the Sherlock Holmes stories by Arthur Conan Doyle. Some of the surviving episode recordings may be found online, in various audio quality condition.

For most of the show's run, the program starred Basil Rathbone as Sherlock Holmes and Nigel Bruce as Dr. Watson. Other actors played Holmes and Watson in later seasons.

Production From the outset of the show, the series was billed in different listings under various titles including Sherlock Holmes, Sherlock Holmes and Doctor Watson, and other titles. The most popularly remembered title is The New Adventures of Sherlock Holmes.[3] On occasion, the title of a radio episode differs from that of its original story – for example, the radio adaption of "The Adventure of the Red Circle" is entitled "Mrs. Warren's Lodger".

From 1939 until 1943, episodes were adapted or written by Edith Meiser[4] who had written the earlier series The Adventures of Sherlock Holmes which aired from 1930 to 1935. Meiser left the show after disagreements with a sponsor over the amount of violence in the program.[5] It is also reported that Meiser left the show to focus on other projects.[6] From 1943 onward, most episodes were written by the team of Denis Green and Anthony Boucher[4] with some early episodes written by Green and Leslie Charteris.[7][8] Edith Meiser returned to write for the show for its seventh season. Max Ehrlich and Howard Merrill wrote the episodes of season 8. Denis Green returned as a writer for the last season.[9]

Originally, the show starred Basil Rathbone as Sherlock Holmes and Nigel Bruce as Doctor Watson.[10][11] Together, they starred in 220 episodes which aired weekly on Mondays from 8:30 to 9:00 pm.[12] Basil Rathbone's last episode as the famous detective was "The Singular Affair of the Baconian Cipher". He was eager to separate himself from the show to avoid being typecast in the role.[citation needed] On October 12, 1946, Tom Conway replaced him in the starring role,[13] though Nigel Bruce got top billing. The new series lasted 39 episodes, and Bruce and Conway then left the series. From then until 1950 the series continued with various actors playing the two principal parts.

The show first aired on the Blue Network but later moved to the Mutual Broadcasting System.[14] The show moved to Mutual in 1943 at the start of its fourth season.[15] The series was originally broadcast from Hollywood. During World War II, the show was also broadcast overseas through the Armed Forces Radio Service. The program aired on ABC instead of Mutual for its sixth and ninth seasons.[16]

Many episodes were recorded in front of a live audience.
