Bestselling author Sandra Harmon uses her inside access to the Mob, law enforcement, and jailed Mafioso Gregory Scarpa Jr. to tell an epic true story of crime and betrayal. The Scarpas were a Mafia dynasty led by Greg Scarpa Sr., so notorious for his addiction to violence and murder that he was nicknamed “The Grim Reaper.” His son, Gregory Jr., a promising young athlete, worshipped his ruthless and manipulative father, and slowly he was drawn into his father’s dark world. What no one but father and son knew was that for thirty years, starting in the 1960s, Scarpa Sr. was an informant, working intimately with FBI handlers. For decades, his connection to the FBI—including the much-publicized agent Lin DeVecchio—protected him, granting him a virtual license to kill.
