Book excerpt: Here is the definitive history of the Watergate scandal—based on the most recently released tapes, in-depth interviews with many of the participants, and hundreds of official and unofficial documents, including notes Haldeman omitted from his own published diaries. Emery's comprehensive coverage and penetrating insights clear up many uncertainties that may still remain about the scandal and the extent of Nixon's involvement. Authoritative and compelling, Watergate is essential reading for anyone who wants to understand fully this traumatizing episode in America's history that challenged the integrity of its political system.
