Set against the disparate worlds of art and intelligence, PORTRAIT OF A SPY moves swiftly from the corridors of power in Washington to the glamorous auction houses of New York and London to the unforgiving landscape of the Saudi desert. Featuring a climax that will leave readers haunted long after they turn the final page, this deeply entertaining story is also a breathtaking portrait of courage in the face of unspeakable evil-and Daniel Silva's most extraordinary novel to date.
