From the New York Times bestselling author of The Brothers Bulger comes the story of Johnny Martorano, whom the FBI called “the most feared man in the underworld.”

Martin Scorsese’s The Departed barely touched his story, but radio talk show sensation, crime reporter, and Boston Herald columnist Howie Carr takes us into the heart of the life of Johnny Martorano. For two decades, Martorano struck fear into anyone remotely connected to his world. His partnership with Whitey Bulger and the infamous Winter Hill Gang led to twenty murders, for which Johnny would serve only twelve years in prison. Carr also looks at the politicians and FBI agents who aided Johnny and Whitey and at the vibrant city of Boston which they so ruthlessly ruled. But most of all, Carr depicts Johnny—the most fascinating crime figure Carr has ever encountered. A plethora of paradoxes, he was Mr. Mom by day and man-about-town by night. Surrounded by fast-living politicians, sports celebrities, and show-biz entertainers, Johnny was charismatically colorful—as charming as he was frightening. After all, he was, in the end, a hitman.
