Explores an often overlooked connection in the JFK assassination. During the late 1950s, Thornley became friends with Lee Harvey Oswald when the two served together in the Marines. He was actually writing a novel based on Oswald three years before John F. Kennedy''s assassination. These connections would later cause New Orleans district attorney Jim Garrison to suspect that Thornley was one of the notorious Oswald doubles and a part of a JFK assassination plot. Well-known conspiracy commentator Adam Gorightly examines these allegations and their validity.
