Books that reveal secrets about history

So far I have not read any book that reveals secrets of history.

Is difficult to believe in a book that reveals secrets, for as are made to be sold, may contain exaggerations or sensational stories just to achieve more sales.

for example, recently saw a book in a showcase that talked about hidden readings Augusto Pinochet, but someone will have a book at home does not necessarily mean you have read.

In my opinion, the biographies are those that give more topics to find secrets about the story, or rather, about historical figures, and even more when they can involve romances or conspiracies. And so one can always speculate who killed Marilyn, or why Bill Gates is so millionaire.

As I searched recently, others to be revealed recurring themes in books are: the Freemasons, the Rosicrucians, the Knights Templarand, and religious issues, especially those having to do with the Catholic Church.

Apparently, apart from the conspiracy, esoteric topics often also attractive, if combined with a little history.

Seeing on the Internet I found books like: "Interview with a Mason", "The Priory", "The Mystery of the holocaust revealed", "We the Rosicrucians", "The Templars and the lost word" and "Code Shakespeare".

In the bibliographical note of "Shakespeare Code" says that those who had previously revealed these codes were victims of relentless persecution.

But the closest thing I've found interesting is that the book "Interview with a Freemason" was written by a social anthropologist at the University of Barcelona.
