The Sicilian is a novel by American author Mario Puzo. Published in 1984 by Random House Publishing Group, it is based on the life of Sicilian bandit Salvatore Giuliano. The plot is connected with Puzo's most famous work, The Godfather (1969), and contains characters from The Godfather. It is regarded as The Godfather's literary sequel and is the second book in The Godfather novel series. It was adapted into a film in 1987, though all Godfather references were removed for copyright reasons in the film adaptation. In this novel, the spelling of Salvatore Giuliano's name was intentionally changed by Puzo to "Guiliano". This novel, though a work of fiction, is based on the real-life exploits of Giuliano.
