One of the most notorious crime bosses in American history, Whitey Bulger was leader of Boston's Winter Hill Gang and topped the FBI's Most Wanted list, despite being an informant for the organization. After 16 years on the run, Bulger was tried and convicted, and only a day after arriving in a West Virginia prison known as "Misery Mountain," he was murdered by fellow inmates. Granted access to exclusive prison letters and interviews, Casey Sherman and Dave Wedge offer new details on Bulger's life on the lam, and the trial that exposed deep corruption within the FBI.
