The Scarpas were a Mafia dynasty led by Greg Scarpa, Sr., a man so addicted to killing that he was nicknamed “The Grim Reaper.” His son, Gregory, Jr., worshipped him and was slowly drawn into his 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 protected him and gave him a virtual license to kill. But faced with arrest in the late 1980s, Greg dropped the dime on his own son. Gregory, Jr., was imprisoned alongside terrorist Ramzi Yousef. He offered to trade information on Yousef with the government in exchange for leniency, providing detailed intelligence on what would eventually result in the September 11th attacks—and more. His warnings were ignored, and he was sentenced to forty years to life in prison, where he remains. A story that gained national notoriety as a result of former FBI agent Lin DeVecchio’s sensational murder trial of 2007, at which Sandra Harmon testified, this is an unforgettable tale of violence, wealth, and sex, set in a world where a man’s word can be everything or nothing at all.
