"Vanished" is a political thriller written in 1968 by Fletcher Knebel, co-author of "Seven Days in May". I usually enjoy these type novels, but was a little disappointed in this one. The story is well written, the characters fairly interesting, and for most of the novel it was quite good. However, as the novel went on it was apparent the close friend and advisor of the President that vanished was on a special top secret mission for the President, which took away much of the mystery. The main character is the Press Secretary, who all in all is not that interesting. He feels abused by the Press, is in love with his younger secretary, and starts to get upset when the President doesn't share everything with him. The novel bounces around to other characters to tell the story, including a very talented black FBI agent, a wall street investor, a big shot investigative reporter, and a lobbyist. The novel's big reveal was that the vanished man was working with others to unit all nuclear scientists to go on strike unless nuclear weapons are dismantled and never seen again. All countries with nuclear weapons go along. (How likely was that in 1968?) The whole thing seemed off. If the President wanted to keep it quite, why stage a headline making disappearance of his advisor. It could have been accomplished by his going on a vacation in Europe, for example. Oh well, it was an interesting novel but overall not really one that stands up.
