To celebrate Arthur Conan Doyle's birthday, we'll hear radio adaptations of four Sherlock Holmes short stories, each featuring a different actor as the great detective. First, Basil Rathbone stars in "The Speckled Band" (originally aired on Mutual on November 12, 1945). Next, we'll hear Tom Conway in "The Adventure of the Dying Detective" (originally aired on ABC on February 3, 1947). Then, it's "The Adventure of the Empty House" (originally aired on Mutual on April 11, 1948). Finally, John Gielgud plays Holmes in "The Bruce-Partington Plans."
