The Three Musketeers (French: Les Trois Mousquetaires) is a novel by Alexandre Dumas, which recounts the adventures of a young man named d'Artagnan after he leaves home to travel to Paris, to join the Musketeers of the Guard. D'Artagnan is not one of the musketeers of the title; those are his friends Athos, Porthos and Aramis, inseparable friends who live by the motto "all for one, one for all" ("tous pour un, un pour tous").
