Miles outside Paris, high-spirited François de La Barre is the carefree teenager who Charles would like to have been, instead of the somber public servant, bound by the Sansons’ motto of duty and honor, who carries out brutal justice in the king’s name. François proves, though, in the sophisticated, treacherous world of prerevolutionary France, to have a dangerous gift for making enemies . . . and when at last their paths converge, in this true story of destiny and conflicting loyalties, Charles must make a horrifying choice.
