On a June night in 1791, King Louis XVI and Marie-Antoinette fled Paris in disguise, hoping to escape the mounting turmoil of the French Revolution. They were arrested by a small group of citizens a few miles from the Belgian border and forced to return to Paris. Two years later they would both die at the guillotine. It is this extraordinary story, and the events leading up to and away from it, that Tackett recounts in gripping novelistic style.
