Ana Montes appeared to be a model employee of the Defense Intelligence Agency (DIA), advancing quickly through the ranks to become its top analyst on Cuban affairs. But for sixteen years Montes sent Castro some of America's most closely guarded secrets and at the same time influenced what the United States thought it knew about Cuba. She is the only member of the U.S. intelligence community ever convicted of espionage for the Cuban government, yet her arrest ten days after 9/11 went largely unnoticed. This book calls attention to the grave damage Montes inflicted on U.S. security--Carmichael even implicates her in the death of a Green Beret fighting Cuban-backed insurgents in El Salvador--and the damage she would have continued to inflict had she not been caught. This inside account of the investigation was written by the DIA counterintelligence investigator who first became suspicious of her activities and, with the FBI, worked over a period of several years to develop a solid case against Montes. Carmichael offers readers a front-row seat on that long and ultimately successful spy hunt. About the Author Scott W. Carmichael, the senior security and counterintelligence investigator for the Defense Intelligence Agency (DIA), served as the lead case agent for the DIA on the Ana Montes espionage investigation. He has been investigating attempts by foreign intelligence services to penetrate DIA operations worldwide for nearly twenty years.
