 Charteris started retiring from writing books following 1963's "The Saint in the Sun".The next book to carry Charteris's name, 1964's "Vendetta for the Saint", was written by science fiction author Harry Harrison, who had worked on the "Saint" comic strip, after which Charteris edited and revised the manuscript.Between 1964 and 1983, another 14 "Saint" books would be published, credited to Charteris but written by others.
