The Just constitutes the third and final of Camus' works known as The Revolts; the first was the novel, Le Peste, or The Plague and the third, the essay, L'Homme Révolté, or The Rebel. The Just is a play based upon real events. To convey his concept of moral revolutionaries, Camus fictionalized the 1905 Moscow assassination of Grand Duke Sergei Alexandrovitch, the uncle of Czar Nicholas II.
When originally published in 1971, The Exorcist became not only a bestselling literary phenomenon, but one of the most frightening and controversial novels ever written. (When the author adapted his book to the screen two years later, it then became one of the most terrifying movies ever made.) Blatty fictionalized the alledgeded true story of a child's demonic possession in the 1940s. Of course, it is still jus a book :)
