Watergate disguised as fiction, by one of the innermost participants, whom Richard Nixon described as "one of the finest public servants I've ever known" when he accepted Ehrlichman's resignation. This book is nominally "about" the CIA (hence the title), but is really about the spying scandal that brought down Richard Nixon, the only President of the United States to resign his office. (Interestingly enough, his vice-president, Spiro Agnew, also resigned, although not due to Watergate.) Personally, I regard Ehrlichman as less than a fine public servant, but nevertheless, his book gives a great deal of insight into not WHAT happened, but WHY it happened...the thirst for enemy intelligence, the need to control outcomes, the desire for revenge. Definitely worth reading, if you were a Watergate Buff.
