National Treasure: Book of Secrets
Just after the end of the Civil War, John Wilkes Booth and another man enter a bar and approach Thomas Gates (Ben Gates’ great-great grandfather). They produce a diary containing an encrypted message, and entice Thomas, a well-known puzzle solver, to decode it. Thomas recognizes the message as using the Playfair cipher and begins to translate it. While he does so, Booth leaves for the theater to assassinate President Lincoln. Thomas Gates solves the puzzle, a clue to a treasure map, and realizes the men are still loyal to the Confederate cause and have a sinister motive for finding the treasure. The Confederate man pulls a gun on him, threatening to shoot him if he doesn’t hand over the diary, however he is distracted from Gates by the chaos errupting in the bar over news of Lincoln’s assassination. Thomas rips several pages from the diary and throws them in the fireplace. The second man shoots him and attempts to retrieve the pages, only succeeding in saving a small piece. The dying Gates gasps, "The war is over," but the man disagrees, stating, "You’re wrong about that, the war has only just begun," and rushes from the bar. With his dying breath, Thomas Gates tells his young son Charles, "The debt that all men pay."
