Helene Hanff, best known for her book "84, Charing Cross Road", was a script writer for the television series version of "The Adventures of Ellery Queen" (1950–1952), which began on the DuMont Television Network but soon moved (in 1951) to ABC. Shortly after the series began, Richard Hart, who played Queen, died and was replaced in the lead role by Lee Bowman. The series returned to DuMont in 1954 with Hugh Marlowe (who had played the role on the radio series) as the title character. George Nader played Queen in "The Further Adventures of Ellery Queen" (1958–1959), but he was replaced with Lee Philips in the final episodes.
