Betrayal: Whitey Bulger and the FBI Agent Who Fought to Bring Him Down is the memoir of Robert Fitzpatrick, a former assistant special agent in charge of the FBI’s Boston office. It was written by Fitzpatrick and his co-author Jon Land. In the early 1980s, FBI headquarters in Washington sent Fitzpatrick to the Boston FBI office to evaluate Whitey Bulger's "suitability" as a high level informant. Instead he encountered an environment that appeared to support and enable Bulger's alleged antithetical behaviors and goals.
