When Pope Paul VII dies suddenly, Gabriel Allon is summoned to Rome by the Holy Father’s loyal private secretary, Archbishop Luigi Donati. A billion Catholic faithful have been told that the pope died of a heart attack. Donati, however, has two good reasons to suspect his master was murdered. The Swiss Guard who was standing watch outside the papal apartments the night of the pope’s death is missing. So, too, is the letter the Holy Father was writing during the final hours of his life. A letter that was addressed to Gabriel. While researching in the Vatican Secret Archives, I came upon a most remarkable book… The book is a long-suppressed gospel that calls into question the accuracy of the New Testament’s depiction of one of the most portentous events in human history.
