In 1952 Welles continued finding work in England, after the success of the Harry Lime radio show. Harry Alan Towers offered Welles another series, The Black Museum with Welles as host and narrator, and this would also run 52 weeks. Director Herbert Wilcox offered him the part of the murdered victim in Trent's Last Case (film), based on the novel by E. C. Bentley. In 1953 the BBC hired Welles to read an hour of selections from Walt Whitman's epic poem Song of Myself. Towers hired Welles again, to play Professor Moriarty in the radio series, The Adventures of Sherlock Holmes.
