"The Strength of the Wolf" presents for the first time a definitive history of the Federal Bureau of Narcotics (FBN) from its birth in 1930 until its wrenching termination in 1968. Carefully and extensively documented, the book is based largely on interviews with former FBN agents, and in this respect "The Strength of the Wolf" represents a new chapter in American history, one that introduces a cast of fabulous characters. Douglas Valentine tells how the FBN's premier case-making agents penetrated the arcane world of international drug trafficking and, by uncovering the Establishment's ties to organized crime, brought about their own demise. As the book reveals in startling detail, the CIA and FBI were often protecting the FBN's major targets in the Mafia and the French Corsican underworld. The CIA and its Nationalist Chinese allies were found to be the largest drug-trafficking syndicate in the world, but for political and national security reasons, the FBN was prevented from investigating this overarching conspiracy.
