This study of Sartre's novels deals with the expression they give to his philosophical and political ideas. Particular attention is given to the technique of narration and to the contribution which Sartre made to the development of the ideas which led to the development of Le Nouveau Roman of the 1950s. The novels are linked to Sartre's whole works, especially to his formal philosophy, critical ideas and plays, and attention is also given to their relationship with his own life.
