I read the book fully, he is 1 year. Thanks to the many historical references and some selected drawings in it, I have almost all retained. Obviously, do not expect to discover the secrets of the organization (which I reminds you is a "secret" society although she storefront). However, if like me, you seek to know his origins, to understand its operation and its history you will be satisfied. For others, the author evokes some works of authors too talkative (which revealed, in their time, Freemasons secrets) it can be a track.
This is not a book that glorifies the Freemasons or the same condemnation if we feel that the author has affection for this community. The book has answered most of my questions I have asked myself and Wikipedia did the rest. I finally understand the films and references used constantly here and there (more or less wisely elsewhere).
The book is really knowledgeable (we refer to reliable and recognized websites without that one is obliged to visit to understand).
Respect!
