Our series of radio detectives played by multiple actors takes us today to Baker Street and four men who donned the deerstalker cap of Sherlock Holmes. First, Basil Rathbone is the great detective in "The Tankerville Club" (originally aired on Mutual on April 22, 1946). Next, Tom Conway steps in as Holmes in "The Adventure of the Horseless Carriage" (originally aired on ABC on February 24, 1947). Then, John Stanley stars in "The Adventure of Lady Waverly's Imitation Pearls" (originally aired on Mutual on April 4, 1948). Finally, John Gielgud is Sherlock in the syndicated episode "The Speckled Band."
