Peter Levenda attempts to assemble (or disassemble, depending on your point of view) a vast web of interlocking coincidences, or more accurately, synchronicities in American history going back to ancient times. I hesitate to label what Levenda writes about as "conspiracy theories" for a couple of reasons. If readers are to consider this a book about "conspiracy theories" they need to know that (and I'm speaking as someone who has read voraciously on all sides of that slippery genre for twenty years) it is NOT a Conspiracy 101 book. One may consider it Advanced Conspiracy Theory for graduate students, not for "conspiracy hobbyists".
Anyone who approaches this book expecting everything to be tied up neatly at the end is going to be disappointed. It is the first of three volumes, and I don't have any idea if Levenda will (or can) come to a succinct conclusion for his thesis in three volumes, or how he's going to get there. I'm dying to find out, though. Even if he doesn't accomplish that feat the wealth of weird, fascinating, and sometimes, downright stunning information makes for a fantastic read for anyone with more than a passing interest in odd history, the occult, etc.
Also included in this first volume (and I feel they are going to pop up again in the other volumes) are Nazi scientists in America after World War II (Operation PAPERCLIP), Nazis in general, JLM Laboratories founder Jack Parsons, his sort-of friend/accomplice and founder of Scientology L. Ron Hubbard, Aleister Crowley, H.P. Lovecraft, the JFK assassination, the CIA, "wandering bishops" (I can't possibly explain this in a blurb), ancient mounds in North America, MK ULTRA, BLUEBIRD, ARTICHOKE, and mind control, LSD, and Charles Manson. Manson seems to be a major thread on the web that runs through these three volumes, but I'm not sure why...yet. Fair warning: these topics barely scratch the surface of all the things Levenda covers in Sinister Forces: The Nine.
As far fetched as that all seems, Levenda pulls primarily from what are considered scholarly sources (end-notes for each chapter), utilizes his vast knowledge and research of the subject while mixing in his sardonic wit and skepticism which distances himself from conspiracy hobbyists who latch on to any theory no matter how ridiculous. He even admits some of the information he covers is astoundingly bizarre and the connections he makes seem far-fetched at a glance, but upon further inspection one realizes they are FACTUAL assertions.
Levenda is no kooky tin foil hat guy with only a youtube channel and a self published book. His research is deep and his insights are unique, fascinating, stimulating, challenging, and above all else highly readable. If you have patience, a strong interest in the subject matter, and the ability to sequester yourself away from distractions and just let yourself slide down the Rabbit Hole you will be rewarded tremendously on multiple levels.
