The stunning new thriller from the master of modern espionage When Pope Paul VII dies suddenly, apparently of a heart attack, legendary spy and art restorer Gabriel Allon is quickly summoned to Rome. The Holy Father's loyal private secretary, Archbishop Luigi Donati, suspects his master was murdered. The Swiss Guard who was standing watch 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 an old friend: 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. For that reason alone, the Order of St. Helena will stop at nothing to keep it out of Gabriel's hands. A shadowy Catholic society with ties to the European far right, the Order is plotting to seize control of the papacy. And it is only the beginning ... Praise for Daniel Silva: 'A spy-fiction master ...
