You mentioned a book called "The Creature from Jekyll Island". Over 20 years ago, I took a 2- week course at the Federal Law Enforcement Training Center (FLETC) in Brunswick GA. Its basically like a military base with barricks, mess hall , etc. On the weekend we were free to leave and I took a day trip with fellow classmates to tour Jekyll Island and St.Simon Island.. As I recall, it had some old mansions and compounds previously visited by the ultra rich. So its interesting to know that this Island figures into the book you mention about the Federal reserve and international banking power!
I was looking into buying book but found this link to a pdf version. Reading it now, and it is very interesting!

Always wanted to know more on this topic, but seems there is sooooo much more to it.
Coolhand, Thank you for telling us about the book.
