IN AMERICAN GANGSTER , THE FEDS TOOK DOWN INFAMOUS HEROIN DEALER FRANK LUCAS. BUT THE KINGPIN BEHIND LUCAS’S CRIMINAL REIGN, LEROY “NICKY” BARNES, REMAINED “MR. UNTOUCHABLE.” UNTIL ONE UNDERCOVER AGENT PROVED TOUGH ENOUGH—OR CRAZY ENOUGH—TO INFILTRATE HIS DOMAIN AND NAIL THE MOST DANGEROUS DRUG CZAR IN AMERICAN HISTORY. Growing up in Red Hook, Brooklyn, where physical violence was a daily reality at home, at school, and on the streets, Louis Diaz had what it took to survive—and to one day become what he vowed to be: a man of uncompromising principles who is “compassionate on the inside, fierce on the outside.” These were the qualities, along with his street fighter’s steely nerves and hair-trigger temper, that drove Diaz from his savage beginnings and early forays in organized crime to become one of the DEA’s bravest undercover agents—the man who was instrumental in taking down some of the nation’s and the world’s most notorious crime rings. In an unforgettable and utterly engaging first-person narrative, Diaz tells his gritty, colorful, painful, and even humorous life story—a story with all the raw emotional power and bare-knuckle action of Wiseguy or Serpico . From his headline-making cases of Nicky Barnes and the Medellín cartel . . . to his account of outwitting a key villain linked to the record-breaking heist known as The Great English Train Robbery . . . to his all-out confrontations with murderous gunrunners and drug dealers on the mean streets of New York . . . to leading commando raids on clan-destine cocaine labs inside the Bolivian jungles, Dancing with the Devil is an explosive memoir that stands as a classic of true-crime literature.
