The precise Englishman Phileas Fogg bets his London club he can circle the world in eighty days and sets off with his servant Passepartout. The race against a fixed deadline across continents supplies the novel's driving structure.
The feat is possible only because railways, steamships, and the Suez Canal have newly stitched the globe into a connected network. Verne dramatizes the nineteenth-century sense that technology and commerce were collapsing distance.
Fogg's imperturbable precision contrasts with Passepartout's improvisation and the pursuing detective Fix's misplaced zeal. The escalating obstacles expose each character's temperament while sustaining suspense.
Fogg believes he has lost the bet by a day until he realizes crossing the international date line eastward gained him twenty-four hours. The clever reversal turns a geographic fact into the plot's satisfying resolution.
