Book excerpt: A New York Times–bestseller from an intelligence insider reveals the “fascinating new research” revealing Hemingway’s hidden life in espionage (New York Review of Books). A riveting epic, Writer, Sailor, Soldier, Spy reveals for the first time Ernest Hemingway’s secret adventures in espionage and intelligence. While he was the historian at the CIA Museum, Nicholas Reynolds, former American intelligence officer and U.S. Marine colonel, uncovered clues suggesting the Nobel Prize-winning novelist was deeply involved in spycraft. Now Reynolds's captivating narrative “looks among the shadows and finds a Hemingway not seen before” (London Review of Books), revealing for the first time the whole story of this hidden side of Hemingway's life: his troubling recruitment by Soviet spies to work with the NKVD, the forerunner to the KGB, followed in short order by a complex set of relationships with American agencies. As he examines the links between Hemingway's work as an operative and as an author, Reynolds reveals how Hemingway's secret adventures influenced his literary output and contributed to the writer's block and mental decline that plagued him during the postwar years. Reynolds also illuminates how those same experiences played a role in some of Hemingway's greatest works, including For Whom the Bell Tolls and The Old Man and the Sea, while also adding to the burden that he carried at the end of his life and perhaps contributing to his suicide. A literary biography with the soul of an espionage thriller, Writer, Sailor, Soldier, Spy is essential to our understanding of one of America's most legendary authors. “Important.” —Wall Street Journal
