In 1760, with the aid of the Indian Shaman Conawago, Duncan McCallum has begun to heal from the massacre of his Highland clan by the British. His new life is shattered when he and Conawago discover a dying Virginian officer nailed to an Indian shrine tree. To their horror, the authorities arrest Conawago and schedule his hanging. As Duncan begins a desperate search for the truth, he finds himself in a maelstrom of deception and violence. While the British army wishes to dismiss the killing as another casualty of its war with France, Duncan discovers a pattern of ritualistic murders that have less to do with the war than with provincial treaty negotiations and struggles between tribal factions. Ultimately he realizes that to find justice, he must go to Philadelphia. There the answers are to be found in a tangle of Quakers, Christian Indians, and a scientist obsessed with the electrical experiments of the celebrated Dr. Franklin. With the tragic resolution in sight, Duncan understands the real mysteries underlying his quest lie in the hearts of natives who, like his Highland Scots, have glimpsed the end of their world approaching
