In mid-1988, a book was published in Italy that caused a lot of noise: an anonymous author offered readers a literary recording of the memoirs of an unknown mafioso named Giovanni. The police began searching for the author of the book and its hero. The effect was unexpected: the author turned out to be the famous writer, master of the detective genre Enzo Russo, the hero of the book was a fictional character, the fruit of the writer's imagination. This is a detective novel, but at the same time it is the fruit of the writer’s careful study of documents about the mafia over many years. This is a truly work of art, a biographical novel that reveals the personality, character of mafioso Giovanni, his psychology.
