In which book would you find the manservant Pas Partout

Around the World in Eighty Days
Jean Passepartout, a character in Jules Verne's novel, Around the World in Eighty Days, is the French valet of the novel's English main character, Phileas Fogg. His surname translates literally to "goes everywhere," but this is an idiom for "skeleton key" in French. It is also a play on the English word "Passport.[citation needed]"

At the beginning of the novel, Passepartout has just been hired by Phileas Fogg after Fogg's previous valet failed to meet his exacting standards. Passepartout, who has lived an irregular and well-travelled life, is looking forward to a restful employment, as Fogg is known for his regular habits which never take him farther afield than the Reform Club.

Ironically, on Passepartout's first day at work, Fogg makes a bet with his friends at the Club that he can circumnavigate the world in no more than eighty days and Passepartout is obliged to accompany him. In addition to the wager, the valet has an additional incentive to complete the journey quickly: he left a gaslight burning in his room and the resulting expense of wasted gas will be docked from his salary.
