His Holiness: The Secret Papers of Benedict XVI (Italian: Sua Santità.

The letters in the book portray the Vatican as a corrupt hotbed of jealousy, intrigue and underhanded factional fighting.

―▶This is the paperback book cover of the above story. It is in Italian language. In my Internet search, I have not been able to find English version of this book yet. Just wonder why a book like this has not been published in US. Is there a conspiracy to keep the book from being read in America? I don't know. (by WM)

Content
Nuzzi's book reveals details about the Pope's personal finances, and includes tales of bribes made to procure an audience with him. It reproduces confidential letters and memos to and from Benedict and his personal secretary. It contains letters from a very senior Vatican administrator to Pope Benedict in which he begged not to be transferred for having exposed alleged corruption that cost the Holy See millions of euros in higher contract prices. The documents also cover a 2009 scandal concerning the ex-editor of the newspaper of the Italian bishops' conference, a dinner between Benedict and Italy's president, and a 2011 letter from an Italian talk show host to the pope enclosing a cheque for 10,000 euros for his charity work – and asking for a private audience in exchange. Diplomatic cables include Vatican embassies from Jerusalem to Cameroon. As well as conclusions of the pope's inquiry into the disgraced Legion of Christ religious order - where he is warned that the financial situation of the order, beset by a scandal over its paedophile founder, "while not grave, is serious and pressing".
The documents portray the Vatican Secretary of State, Cardinal Tarcisio Bertone, in a particularly negative light.

Leaked information
Paolo Gabriele, Pope Benedict's personal butler from 2006 to 2012, is believed to have leaked the stolen information to the author. He is now being held by Vatican police, who claim to have found classified documents in his apartment, and will face trial for stealing confidential papers. If found guilty of leaking the private and confidential Vatican documents, he faces up to six years in an Italian prison after being tried, per Vatican canon law and applicable Vatican-Italian concordat agreements, by the Vatican judicial system- through one of the Vatican courts that handle non-religious, secular offenses (as opposed to the Roman Rota, the Apostolic Penitentiary, or the Apostolic Signatura, which deal with serious, often appellate, cases dealing with confession, religious, or Curial affairs). Gabriele told investigators he acted because he saw "evil and corruption everywhere in the church."
