Under the code-name "Deep Throat," Mark Felt provided vital information to Washington Post reporter Bob Woodward, a scoop that would bring down Richard Nixon's presidency. In 1982, Felt documented his personal recollections of the Watergate scandal, explaining how he came to feel that the FBI needed a "Lone Ranger" to protect it from White House corruption. In this memoir, he supplements this material with an absorbing account of his FBI career, from the end of the great American crime wave through World War II, the culture wars of the 1960s, and his controversial role in penetrating the terrorist network Weather Underground.
