The riveting account of former head of Massachusetts State Police Thomas J. Foley’s twenty-year pursuit of murderous Boston gangster Whitey Bulger—and of Foley’s key role in exposing the FBI’s protection of Bulger’s criminal empire.

On June 23, 2011, James “Whitey” Bulger, fugitive Boston mob boss, #1 on the FBI’s Most Wanted list, was arrested after sixteen years on the lam. Incredibly, it was a member of the FBI who originally tipped off Bulger to his impending arrest, undoing nearly two decades of painstaking investigation by a small band of state police officers.

Most Wanted is the story of the campaign, led by Massachusetts State Police Col. Thomas J. Foley, to bring down America’s most brutal crime boss and the painful discovery that Bulger was actually an FBI informant, a rat providing inside information about rivals and witnesses—some of whom wound up dead—in exchange for protection. And in many instances, the man the FBI was protecting Bulger from was Tom Foley, effectively derailing Foley's efforts time and again.

For Foley, life was a double chase: he was going after Whitey while the FBI was going after him. Most Wanted follows the tale as it unfolded, event by event, each one contributing to the deepening truth: that the despicable mendacity of Whitey Bulger was matched only by the terrible corruption of the FBI agents who made his crimes possible.
