The New Adventures of Nero Wolfe, airing from October 20, 1950, to April 27, 1951, on NBC, was an American radio drama series featuring Rex Stout's armchair detective, Nero Wolfe, played by Sydney Greenstreet. The show followed Wolfe as he solved cases without leaving his home, relying on his assistant Archie Goodwin to collect facts and report back. Archie's character was portrayed by several actors, including Gerald Mohr and Lawrence Dobkin. Produced by Edwin Fadiman and directed by J. Donald Wilson, the series was known for its focus on characterization over plot. It was the third radio adaptation of Nero Wolfe and is seen as the most responsible for popularizing the character on radio. Despite Sydney Greenstreet's health issues, all episodes except "The Case of the Headless Hunter" have survived in radio collections.
