Secret societies have flourished for many centuries in many different cultures. Though some, like the Shriners, perform semi-public activities, not much is known about what goes on within them – that’s why they’re called ‘secret.’ This lack of knowledge has led the mysterious groups to captivate our cultural imagination, as unexplained coincidences and nefarious plots are attributed to them.

If you’ve watched The Good Shepherd, National Treasure, or read about the V.F.D in A Series of Unfortunate Events, then you’ve already been exposed to how fun and engrossing the idea of a sinister secret society can be. To help you find more things to enjoy in that vein, here’s a round-up of books that feature shadowy groups, conspiracy theories, and men in fezzes.

The Illuminatus! Trilogy by Robert Shea and Robert Anton Wilson

If you want to get the most bang for your buck, conspiracy-wise, start with the Illuminatus! trilogy. Every weirdo theory out there is covered, and connected to the most secretest secret society of all – the Illuminati. There are lots of symbolic eyeballs, and you’ll be eyeballing your surroundings after reading it, especially that buck – what’s the deal with that spooky staring pyramid, anyway?

 The New Avengers: Illuminati by Brian Michael Bendis, Brian Reed, and Jim Cheung

This is a kinder, gentler Illuminati. Sort of. A gathering of well-known powerful Marvel comics characters are revealed as having manipulated several important events from behind the scenes. Their intentions are mostly good, but as with many tales of good versus evil, things get muddy, and what Professor Xavier, Tony Stark, and Doctor Strange (among others) resort to meet their goals may not always be so nice.

 The Boys From Brazil by Ira Levin

Can you have a good secret society/conspiracy theory reading list without Nazis? No, you cannot. Nazis are the fallback conspiracy of literature at large. So, here is a book about secret Nazis hiding in South America and plotting to kill six aging men. Why do they want to kill these six men in particular? What are the connections between them and the exiled SS members? The writing has been described as ‘cinematic,’ which explains why there is a movie version.

The Incrementalists by Steven Brust and Skyler White

The members of the secret society in this group want to save the world and make it a better place – but very slowly, over hundreds of years and multiple reincarnations. One could say they want to do so in increments. The plan seems to be progressing well, if at a glacial place, but then something goes wrong with the lovebirds who star in the story, and they go wrong rather quickly, as they often do.

Ritual America: Secret Brotherhoods and Their Influence on American Society, a Visual Guide by Adam Parfrey

Most of the secret societies on this list are fictional, but as we mentioned before, there have been real ones throughout history. This book takes a comprehensive look at the secret fraternal societies of America in particular, describing their history, traditions, and influence. As indicated by the ‘visual guide’ part of the title, almost every page features reproductions of fraternal memorabilia, including many snapshots of men in aprons and silly hats.
