The Messenger

An art restorer and spy, Gabriel Allon, faces his biggest challenge yet after being approached by Monsignor Luigi Donati, who suspects the death of a young Swiss guard in St. Peter's Basilica was murder, not suicide. As Allon investigates, he uncovers a conspiracy of lies and deception that leads him from the Vatican to Switzerland and beyond, where he discovers an extraordinary enemy with the goal of the most spectacular assassination ever attempted.
