The Chancellor Manuscript, Robert Ludlum

The Chancellor Manuscript is a 1977 novel, by American writer Robert Ludlum, about the alleged secret files of J. Edgar Hoover and how they disappeared after his death, and how they possibly could be used to force people in high places to do the bidding of those who possessed the secrets contained therein. It also speculated that Hoover himself might have been assassinated because he knew too much about too many of the wrong people.
