(from the back cover) The Adventures of Baron Munchausen, one of the most famous liars in history... This book tells the story of Terry Gilliam and Charles McKeown's exciting and hilarious new screenplay, which shows a company of actors in a besieged town - headed by Henry Salt Esq., the internationally famous actor manager and abetted by his daughter Sally. The play they perform retells the story of Baron Munchausen, but it is interrupted by an aged and outraged member of the audience who claims to be the Baron himself. Only nine-year old Sally will believe that he really is the Baron and so begins an exciting and enthralling series of adventures for them both, which starts with a daredevil wager against a murderous sultan and takes them to the moon and beyond.
