For half a century, the case of Isaiah Oggins, a 1920s New York intellectual brutally murdered in 1947 on Stalin's orders, remained hidden in the secret files of the KGB and the FBI a footnote buried in the rubble of the Cold War. Then, in 1992, it surfaced briefly, when Boris Yeltsin handed over a deeply censored dossier to the White House. The Lost Spy at last reveals the truth: Oggins was one of the first Americans to spy for the Soviets. Based on six years of international sleuthing, The Lost Spy traces Oggins's rise in beguiling detail a brilliant Columbia University graduate sent to run a safe house in Berlin and spy on the Romanovs in Paris and the Japanese in Manchuria and his fall: death by poisoning in a KGB laboratory. As harrowing as Darkness at Noon and as tragic as Dr. Zhivago, The Lost Spy is one of the great nonfiction detective stories of our time.
