Throughout the early 1940s on American Radio, Basil Rathbone and Nigel Bruce performed as Holmes and Watson, respectively, in several series of canonical and original Sherlock Holmes stories. When Rathbone finally departed the role before the 1947 season, Tom Conway played Sherlock Holmes opposite Nigel Bruce for one season. After a change of networks, there were two more pairings: John Stanley as Holmes and Alfred Shirley as Watson in 1947-1948 and John Stanley and Ian Martin in 1948-1949.
