The final volume of Remembrance of Things Past chronicles the years of World War I, when, as M. de Charlus reflects on a moonlit walk, Paris threatens to become another Pompeii. Years later, after the war's end, Proust's narrator returns to Paris, where Mme. Verdurin has become the Princesse de Guermantes. He reflects on time, reality, jealousy, artistic creation, and the raw material for literature-his past life.
