June 23, 2011. The news of the notorious gangster Whitey Bulger's capture--after sixteen years on the FBI's Most Wanted list--swept the nation. Many breathed a sigh of relief. But for Thomas J. Foley, a former Massachusetts state police colonel and the investigator who sparked Bulger's flight from Boston, the moment was bittersweet. The FBI may have caught Bulger, but as Foley had painfully discovered almost two decades before, they were also responsible for his escape.

It has been known that Whitey Bulger was a secret informant for the FBI, but it has never been revealed--until now--that the FBI was actually actively protecting Bulger from Foley, effectively derailing Foley's efforts to stop Bulger's horrific crime sprees time and again. At one point, the FBI even presented Foley with a plaque at a holiday party that read "the Most Hated Man in Law Enforcement," a not-so-subtle suggestion that he and his team should lay off their investigation.

Most Wanted is a true-life thriller, and Foley is the hero at its center. His investigative efforts resulted in criminal convictions of a half-dozen of Boston's most notorious thugs and also led to the conviction of John Connolly, one of the FBI agents who abetted Bulger; Connolly is now serving a forty-year prison sentence. In this book, Foley, a cop's cop, honestly recounts how his wide-eyed admiration for the nation's top law enforcement agency was gradually transformed by dark realities he didn't want to believe.
