The Adventures of Biggles. Major James Bigglesworth, generally known as Biggles, was a fictional character created by Captain W.E. Johns in the 1930s. Chronicling his own WWI experiences, Johns went on to write almost 100 stories about Biggles, including WWII and peace time adventures as well. If you're interested in learning more about Biggles, why not try the International Biggles Association, or a complete illustrated list of all stories, including plot summaries? Or perhaps Monty Python's take on Biggles is more your style.
While nearly every title catches my fancy, my favourites must be Biggles Gets His Men, Biggles Cuts It Fine, Biggles Flies North (with a visit to Camp Beaver), and of course the classic Biggles Takes It Rough.
