Ben Franklin, the ambassador to France, and Marie Antoinette, the queen of France, have been kidnapped!
George Washington sends Colonels Hamilton and Burr, Captain Adlum, and secret agent 351, Elizabeth Schuyler, to France, and they meet up with Beaumarchais, the king’s right-hand man, in wild pursuit across Bavaria. All this time, Franklin has been having an affair with Marie Antoinette in a castle in Bavaria, who is part of a Europe-wide plot to stop the American War of Independence, a position very much at odds with her husband’s. But Franklin, held against his will in a castle in Bavaria, is too clever for the best minds of Europe and breaks free of his captors in a balloon chase across the Black Forest. All along, the king of France has been having marital problems, and in the end, Ben reunites the king and queen, and America gets its funding from the king for the war of independence, now in its second year.
