What is the author's style in The Immoralist by Andre Gide?

The narrative structure and point of view of The Immoralist is somewhat complex. The novel begins with what is called a frame narrative, meaning a brief explanation of the context of the central narrative. Thus, the first two pages of The Immoralist are written in the form of a letter from an unnamed man to his brother, a Monsieur D. R., explaining that Michel summoned his three longtime friends—Denis, Daniel, and "I"—to travel to his hotel in Sidi, North Africa, on an urgent matter. The letter states that Michel told his story to these three friends one night while lounging on his terrace. The letter writer indicates that he has written down Michel's story as it was told to these friends, and that this transcript of the story is enclosed in the letter.
