Redwood: The Untold Story of the Cold War's Most Extraordinary Spy Hardcover – September 15, 2026

From the bestselling author of The Spy and the Traitor (“John le Carré’s nonfiction counterpart”—The New York Times) comes the ultimate true-life Cold War thriller: the story of a Russian double agent with a terrible secret—and the key to stopping a nuclear apocalypse. The year is 1981. Tehran is in violent turmoil in the wake of the Iranian Revolution. The Soviets are planning to overthrow the Ayatollah’s fledgling Islamist regime. If they do so, one response contemplated in the secret chambers of American power—unknown to the public—would be to strike with nuclear weapons. Redwood is the story of how, at the height of the Cold War, one mysterious double agent, whose intelligence reached the highest levels of American and British governments, cracked open the KGB, revealed the Kremlin’s secret plot, and prevented Armageddon.“Redwood” was the MI6 codename for this unsung, hitherto-unknown hero of the Cold War, a highly trained, six-foot-four Russian intelligence officer who chose to expose the KGB’s deepest secrets, compelled to swap sides by a shaming secret of his own. Facing exposure, with both the Iranian Revolutionary Guards and his own KGB colleagues closing in, he demanded that MI6 try to smuggle him out of Iran in a high-stakes escape plan.This is the gripping tale of one man’s courage, and its extraordinary unintended consequences that still shape our world today. It’s about a moving friendship between spies on opposite sides of the global conflict; about marriage, loyalty, betrayal and sexual dysfunction; and about how decisions made in secret can have huge, long-term ramifications. Drawing on never-before-seen material from archives in multiple countries, and interviews with the participants including officers from MI6 and MI5, the KGB and CIA, Redwood plunges readers back into the shadowy world of The Spy and the Traitor. It lifts the lid on an unknown and highly significant Cold War victory, on the machinations of history’s Great Game, and on how espionage really works. Without Redwood, our world would be very different—and might not exist at all. Read more
