The Free Masons have long been the subject of suspicion and intrigue. The mysterious society has sparked public interest and popular culture, resulting in the popular Nicolas Cage movie National Treasure and Dan Brown’s novel The Lost Symbol. One of the first books on the subjects, however, was The Lost Keys of Freemasonry.

In his book, Manly P. Halls—a scholar of the occult and a high-ranking Mason himself—writes about the society that has captivated public opinion for centuries. Halls tells of the ancient history of the society and the philosophy that it still follows to this day. Hall recounts the ethical training that new recruits must go through to join the Mason’s circle and the qualities that they must build as they journey through the ranks of the society.

The new edition of this book can be enjoyed by audiences ranging from Free Masons themselves to those simply interested in cults and secret societies.
