A critical and commercial success, the books present four perspectives on a single set of events and characters in Alexandria, Egypt, before and during World War II. As Durrell explains in his preface to Balthazar, the four novels are an exploration of relativity and the notions of continuum and subject-object relation, with modern love as the subject. The Quartet offers the same sequence of events to us through several points of view, allowing individual perspectives to change over time.
