These guys are awesome. Secret codes! Daring missions! Dazzling escapes! And awesome spy gear!
These are awesome adventure stories. And they're 100% true.
Thomas B. Allen makes James Bond look lame next to these guys.
And the books (George Washington, Spymaster: How the Americans Outspied the British and Won the Revolutionary War and Harriet Tubman, Secret Agent: How Daring Slaves and Free Blacks Spied for the Union During the Civil War) are even cooler--not only are there secret messages in the gutters for you to decode, there are appendixes, end notes, bibliographies and further reading.
End notes! With in-text numbers to reference them. End notes! In a juvie nonfiction book. Be still my fluttering, dorky heart.
I mean, I always knew these guys did cool things. There's a reason we still talk about them. I didn't quite appreciate how much they kicked ass.
I highly recommend for everyone.
