I like that phrasing "The Hidden Hand." I'm glad I caught this, because I must be the goat who likes that phrase the most. I've often thought how I'd like to read every book entitled, "The Hidden Hand." I just finished A.H. Lane's a month or so ago. Cherep-Spiridovich's book is called, "The Secret Government or The Hidden Hand." There's this from a guy named Aldrich (a Rockefeller name): https://www.amazon.com/Hidden-Hand-Britain-America-Intelligence/dp/1585672742
