I had to work with this book in my studies in Italian language and it was a great pleasure for me to know this author. He describes brillantly the relations in the big family, where nobody owes to say a word about the big bosses and the crimes, which have happened. This silence, omertá, causes the power of the mafia. Regarding this system the officer gets frustrated, because there's no chance for him to arrest the big boss, which is evidently not innocent. My comment about this book is very positive and I could tell everybody to read it, too.
