*An Amazon Best Book of 2023* *An Apple Book of the Month for January* "This is the definitive history of how one of America's most highly regarded intelligence analysts betrayed her country, and how she almost got away with it." --Pete Williams, former NBC News justice correspondent Investigative journalist Jim Popkin weaves the tale of two sisters who chose two very different paths, plus the unsung heroes who fought to bring Ana Montes to justice. With exclusive access to a "secret" CIA behavioral profile of former US intelligence community superstar Ana Montes, family memoirs, and Ana's incriminating letters from prison, Popkin reveals the making of "one of the most damaging spies in US history." After more than two decades in federal prison, Montes was freed in January 2023, and this new paperback edition includes an update on her activities since leaving prison. "Popkin keeps the reader hooked until the handcuffs are slapped on, and beyond." --Star Tribune "Code Name Blue Wren earns a prestigious four out of four trench coats." --The Cipher Brief
