Coluccello's book on Mafia's legitimisation. In Natoli's novel, the Beati Paoli act not out of economic interest but solely on moral grounds, for the sake of justice. As put by the main leader of the organization: "our justice is not written on any royal charter, it is written on our hearts: we follow it and we force others to follow it".
