In the build-up to Sunday's premiere of Turn, the Revolutionary War thriller based on Alexander Rose's fascinating 2007 book Washington's Spies, AMC has released a beautifully illustrated online comic that details the backstories of the members of the Culper spy ring.

Turn: Origins is drawn by Steve Ellis, known for his work on High Moon, Box 13 and The Only Living Boy, and penned by Turn writer LaToya Morgan, whose credits include Shameless and Parenthood. Kevin Colden did the lettering.

Premiering Sunday at 9 p.m. ET/PT, Turn stars Jamie Bell as Abe Woodhull, a farmer living in British-occupied Long Island who bands together with his childhood friends to form the Culper Ring, an unlikely team of secret agents who not only went on to help George Washington turn the tide of the war but also gave birth to modern spycraft.
