Goodfellow, capo, killer, thief. A man so diabolically evil that he ordered his eldest son to murder his closest associate, and his youngest son to murder his best friend.

When Greg Scarpa was in his early twenties he became a goodfellow in the Profaci family by swearing a blood oath to the Mafia, at the time the country's largest organized-crime syndicate. And for 25 years he betrayed that oath and the men closest to him by acting as a paid informant for the FBI. He fed America's premier law enforcement agency a steady stream of self-serving information accusing the men who trusted him with their lives of every crime he was himself committing. During those 25 years of treachery, Scarpa was a one-man crime wave who spent only 30 days behind bars thanks to his status as the FBI's ultimate Mafia insider. His standing as a prized informant freed him to engage in mayhem and murder knowing he had a virtual license to kill with reckless abandon.

Greg Scarpa, Legendary Evil is a deep dive that provides fresh insight into Scarpa's malignant personality. Dyer peels

back the layers of myth and misdirection to paint as complete and accurate a picture as possible of a man who murdered his enemies and betrayed his friends, of a bigamist who loved only money, of a feared and reviled man whose destructive appetites knew no bounds.
