The game is afoot with three old time radio mysteries starring the master detective of Baker Street, Sherlock Holmes. Sir Arthur Conan Doyle’s immortal character made his debut as a radio sleuth on October 20, 1932, and we’re celebrating his anniversary with radio adventures starring three different actors as Holmes. First, Basil Rathbone is Holmes, with Nigel Bruce as Watson, in “The Case of the Limping Ghost” (originally aired on Mutual on September 3, 1945). Next, John Stanley and Alfred Shirley are Holmes and Watson in “The Sussex Vampire” (originally aired on Mutual on December 14, 1947). Finally, John Gielgud and Ralph Richardson star in “The Final Problem” (originally aired on NBC on April 17, 1955), featuring special guest star Orson Welles as Professor Moriarty.
