Giovanni's Ring is the story of "Giovanni Rocco," a New Jersey police officer, known undercover as "Giovanni Gatto," who spent over twenty years in various undercover roles, penetrating biker gangs, drug cartels, white supremacist groups, and domestic and international terror groups. Most significantly, he was the mysterious agent at the epicenter of Operation Charlie Horse, a federal undercover operation that ultimately brought down ten members and associates of New Jersey's DeCavalcante Mafia family--the criminal organization otherwise known to law enforcement as "the real Sopranos." Giovanni spent nearly three years working his way into the DeCavalcante hierarchy. He was so convincing in his role that capo Charlie "the Hat" Stango (also known as Charlie "Beeps") began to treat him as his "right hand." Over time, the personal relationship between the two men grew to a point where Charlie treated Giovanni more as a favored son than just an associate. Giovanni became so fully trusted that Stango went "on the record" for him with the family's administration and put him in charge of his own crew. Giovanni was permitted to attend meetings with other high-ranking members of the DeCavalcante crime family, as well as with senior members of New York's notorious Gambino, Genovese, and Lucchese Mafia families, and was authorized to speak on his capo's behalf. Each passing day became a roll of the dice for Giovanni, plaguing him with doubts: Is today the day my cover is blown? Is this the last day I see my wife and children? Will one of my deals between families or crews go bad and I'll get clipped? Is this all worth it? Stango eventually assigned Giovanni the task of killing Luigi "the Dog" Oliveri, a troublesome made member of the crime family. That lethal assignment brought the undercover operation to an end in March 2015, and the resulting string of high-profile arrests eviscerated the criminal organization. In the course of the operation, Giovanni secretly recorded hundreds of conversations relating to a wide range of crimes including counterfeit and contraband goods trafficking, warehouse robberies, truck hijackings, and drug trafficking. Also, and importantly for his own safety, he learned that the DeCavalcante family had secured access to sensitive law enforcement information, including information about specific investigations into DeCavalcante members and associates. Giovanni's Ring is not simply a chronicle of Giovanni Rocco's adventures in the murky and dangerous Mafia world he inhabited, but also a fascinating window into the psychological struggles that such a life inevitably entails. Whenever Giovanni returned to his real home and his real family, he needed to perform an invariable ritual: he parked in his driveway, removed his jeweled pinky ring, and dropped it in a cup holder, trying to drop the Gatto identity as well. Giovanni's Ring is a story that is by turns astonishing, electrifying, gut-wrenching, and always deeply human.
