Field Guide to Secret Societies examines the exploits and details the history of a wide variety of organizations, from the obvious (Freemasons, Rosicrucians) to the mysterious (Hai San, the Bohemian Club), and from the bizarre (Independent Order of Odd Fellows, Ordo Templi Orientis) to the frightening (Ku Klux Klan, Bilderberg Group). Some are more active and famous than others. Some are harmless whereas others pose a threat, but whether that threat is real or imaginary will be up to the reader to judge.

If you know where to look and what to look for – and this book tells you just that – secret societies are indeed everywhere. Using the information inside, the eagle-eyed reader will be able to identify the hallmarks, members and handiwork of secret societies, many of which are still operating today.

People, places, architecture and other clues are there to be found, hiding in plain sight, and Field Guide to Secret Societies shows where they came from, whether they still exist (if known!) and details what purpose they serve.
