Or the hidden agenda of secret societies? With every major cornerstone laid by Freemasons, was the city built in a Masonic pattern? Embark upon this incredible journey as Riddles in Stone interviews experts on both sides of the heated debate. Watch as Freemason apologists defend some of the most direct and hard-hitting questions concerning the influence of Masonry in America, and its symbolism in Washington, D.C.
