In the latest thrilling Cotton Malone adventure from international bestseller Steve Berry, one by one the seven precious relics of the Arma Christi , the weapons of Christ, are disappearing from sanctuaries across the world. After former Justice Department agent Cotton Malone witnesses the theft of one of them, he learns from his old boss, Stephanie Nelle, that a private auction is about to be held where incriminating information on the president of Poland will be offered to the highest bidder - blackmail that both the United States and Russia want, but for vastly different reasons. The price of admission to that auction is one of the relics, so Malone is first sent to a castle in Poland to steal the Holy Lance, a thousand-year-old spear sacred not only to Christians but to the Polish people, and then on to the auction itself. But nothing goes as planned and Malone is thrust into a bloody battle between three nations over information that, if exposed, could change the balance of power in Europe. From the tranquil canals of Bruges, to the elegant rooms of Wawel Castle, to deep beneath the earth in an ancient Polish salt mine, Malone is caught in the middle of a deadly war - the outcome of which turns on a secret known as the Warsaw Protocol.
