The Adventures of Sherlock Holmes is an American old-time radio show that aired on US radio networks between 1930 and 1936. The series was adapted from Sir Arthur Conan Doyle's Sherlock Holmes stories by scriptwriter Edith Meiser. For most of the series, Richard Gordon played Sherlock Holmes and Leigh Lovell played Dr. Watson. The series included multiple original stories by Meiser, in addition to Meiser's adaptations of all of Doyle's Sherlock Holmes stories except one. Some episodes in the series were remakes of scripts that had been used for episodes in earlier seasons of the show.
