Paul VI was a spy, claim authors

THE FUTURE Paul VI was an Allied "informer" against Germany and Japan during World War II in a secret pact between American and British Intelligence and the Vatican.
Then a trusted Secretariat of State counsellor, Giovanni Battista Montini who would become Pope 20 years later agreed to report to the US Ambassador to the Holy See during the war, Myron Taylor, and to his deputy.
According to a book by the Italians Ennio Caretto and Bruno Marola, the future Pontiff secretly handed over information he received from the apostolic nunciatures in Berlin and Tokyo. He also kept the British informed of events in Rome, which was occupied by the Nazis at the time.
