This absorbing account of Mark Felt's FBI career, from the end of the great American crime wave through World War II, the culture wars of the 1960s, and his conviction for his role in penetrating the Weather Underground, provides a rich historical and personal context to the "Deep Throat" chapter of his life. It also provides Felt's personal recollections of the Watergate scandal, which he wrote in 1982 and kept secret, in which he explains how he came to feel that the FBI needed a "Lone Ranger" to protect it from White House corruption.
