Pham Xuan An was a brilliant journalist and an even better spy. A long-time correspondent for Time and friendly with all the legendary reporters covering Vietnam, he was an invaluable source of news and font of wisdom on all things Vietnamese. At the same time, he was a masterful double agent, a North Vietnamese intelligence agent whose secret reports were so admired by Ho Chi Minh that he clapped his hands with glee on receiving them and exclaimed, “We are now in the United States’ war room!” An inspired shape-shifter who kept his cover in place until the day he died, Pham Xuan An ranks as one of the preeminent spies of the twentieth century. When Thomas A. Bass set out to write the story of An’s remarkable career forThe New Yorker, fresh revelations arrived daily during their freewheeling conversations, which began in 1992. But a good spy is always at work, and it was not until An’s death in 2006 that Bass was able to lift the veil from his carefully guarded story to offer up this fascinating portrait of a hidden life. A masterful history that reads like a John le Carré thriller,The Spy Who Loved Usoffers a vivid portrait of journalists and spies at war.
