Question: Were  Sidney Sheldon and W. Somerset Maugham both writers?
Context: Robert Lorin Calder, a Canadian writer and professor, won the Governor General's Award for English-language non-fiction in 1989 for his "Willie: The Life of W. Somerset Maugham", a biography based on extensive archival work and interviews with surviving associates of Maugham, in particular Alan Searle.  Unlike Ted Morgan, who had obtained permission from Maugham's executors to publish from Maugham's letters in his biography (1980), Calder was refused permission to do so by the Royal Literary Fund and had to rely on paraphrase in referencing Maugham's unpublished correspondence.
