It was the most popular of Verne's Voyages extraordinaires series of novels.Phileas Fogg, a London gentleman of meticulous and unchanging habits, hires as his valet Jean Passepartout, a Frenchman who has had a variety of jobs, including circus performer, but now seeks a tranquil life. After reading in The Daily Telegraph that a new railroad in India has made it theoretically possible to travel around the world in 80 days, Fogg bets his fellow members at the Reform Club that he will make that journey in 80 days or less; the wager is for the princely sum of £20,000 (half his fortune). Leaving that night, Fogg and a nonplussed Passepartout board a train bound for Dover and Calais to begin their journey.
