 Upon publication of his book, Yallop agreed to donate every penny he made from sales to a charity of the Vatican's choice if they agreed to investigate his central claim, that when the body of the pope was discovered, his contorted hand gripped a piece of paper that was later destroyed because it named high-ranking members of the curia who were Freemasons and others who had a role in numerous corruption scandals and the laundering of mafia drug money.One of the names believed to be on the paper was that of Bishop Paul Marcinkus, who was later promoted by Pope John Paul II to Pro-President of Vatican City, making him the third most powerful person in the Vatican, after the pope and the secretary of state.None of Yallop's claims, which are unproven, has thus far been acknowledged by the Vatican, although Yallop disclosed the amount of Masonic Lodge members from the Curia, whom he alleged to be Freemasons, within the pages of his book.
