The true story of Mary Surratt, a shadowy figure behind the assassination of Abraham Lincoln--and the first woman executed by the federal government. Surratt, a Confederate sympathizer, ran the boarding house in Washington where the conspirators, including her rebel son, John Surratt, met to plan the assassination. When a military tribunal convicted her for her crimes and sentenced her to death, five of the nine commissioners petitioned President Andrew Johnson to show mercy on Surratt because of her sex and age. Unmoved, Johnson refused-- Surratt, he said, "kept the nest that hatched the egg." A movie made retelling this moment in American history, is called The Conspirator , directed by Robert Redford.
