Balthazar, published in 1958, is the second volume in The Alexandria Quartet series by British author Lawrence Durrell. Set in Alexandria, Egypt around World War II, the four novels tell essentially the same story from different points of view and come to a conclusion in Clea. Balthazar is the first novel in the series that presents a competing narrator, Balthazar, who writes back to the narrating Darley in his "great interlinear."
