Christopher Dickey, foreign editor of The Daily Beast and author of Our Man in Charleston: Britain's Secret Agent in the Civil War South (Crown, 2015), introduces us to Robert Bunch, the British Spy who prevented Great Britain from supporting the Confederacy during the Civil War. 

Christopher Dickey speaks of the documentary he made in 1974 about his uncle's obsession with Civil War ordinance and the final scene: defusing a 100-pound projectile in his basement.
