As the head of Vatican security, Giovanni Figlia must protect a new, African Pope who courts controversy every other day. The Pope's latest project is to make Pius XII, "Hitler's Pope," a saint. Things haven't gotten better since the Pope employed American mercenary Sean Ryan. Then a body fell onto the Vatican doorstep. Soon, a pattern emerges-- people who go into the Pius XII historical archives are dying. Each time, a priest has been in the background-- a priest close to the Pope. One of the victims was an al-Qaeda operative, drawing Scott "Mossad" Murphy of Israeli intelligence to Rome. Soon, Ryan, Murphy and Figlia must join forces to unravel the mystery around the Vatican, as even the man Giovanni is supposed to protect looks like a suspect. To get out of this alive, they must discover if Hitler's Pope was a Nazi collaborator, or a pious man.
