Gabriel Allon, the Israeli spy in many of Daniel Silva’s novels, is cast against terrorist groups from al-Qaeda and the sword of Allah who would attack the Vatican and kill the Pope and/or the U.S. President should their schemes succeed. The Secret Servant follows The Messenger and includes many of the same characters and intrigues of the prior novel. These adventures give the reader a bad taste for most of the antagonists and an appreciation for Israeli secret service. The Secret Servant has an extra twist of an Arab willing to help the Israelis in an effort to save a woman’s life as well as that of his own son. In both novels, a young woman is in great danger in the hands of terrorist but Allon and his team come to the rescue.
