This is a series to which I've been looking forward. I spent a fair amount time while working at the Fraunces Tavern Museum -- another center for Washington's spies -- looking at the activities of the Culper Ring.
For background in this action of the War of Independence there is an excellent book, Washington's Spies: The Story of America's First Spy Ring (2006), by Alexander Rose.
For a detailed background and shooting of the AMC Turn, Hank Stuever of the Washington Post has written one, which can be read here (with the caveat -- really? the only comparison, Mr. Stuever, you can make about the character of
General Washington and the actor playing him is to frackin' Don Draper? -- how pathetic is that -- even though Mad Men is an AMC show? Television writing has a long way to go ....)
Personally, I find it more than ironic, considering our national history, particularly of who held the presidency more than any other state or region, that the shooting of Turn -- a story of the role of the New York region -- is done in Virginia. Even in television Virginia 'owns' all of our history: all of it still belongs to Old Dominion, as it has always and still claims!
