The true writer of the popular boy series was Leslie McFarlane who used the pseudonym of Franklin W. Dixon with other writers. This American sleuth boy series was written not by a true blood American but by a Canadian. The Hardy Boys, a project on which Leslie was the main contributor, wrote 19 of the first 25 books between 1927 and 1946, and 21 overall. Just who was Leslie McFarlane? This seems like a mystery that only the Hardy Boys can solve. Ghost of the Hardy Boys: The Writer Behind the World’s Most Famous Boy Detectives explores the true origins of the writings of the Hardy Boys series.
