Summary: This series was based upon a character developed in over 40 motion pictures of the 1930s and 1940s starring Warner Oland and Sidney Toler and Roland Winters. It was also a sequel to several radio series. The films and radio series were based upon a character created in novels of Earl Derr Biggers, but were said to have been loosely based on the life of Honolulu police detective named Chang Apana.
