Newfag here, Anon. Potential rabbit hole to go down re: Episcopal Church. Dig on Walter Bosely's Empire of the Wheel trilogy. Bosely is ex-Mason / former FBI. Trilogy gets into 1915 San Bernadino occult murders incl Cora Stanton (Episcopal Nun / secret agent?). Butch Cassidy & Sundance Kid, US Treasury, mysterious Germanic "NYMZA" Secret Space Program in the 18th/19th century. Wild, but legit sounding research.
