The turn of Revolutionary War events after 1780 brings adventure to 15 year old Lesley Ross, at home near New London . Her brother Nat is off with Washingtons's Army and Lesley meanwhile looks forward to a visit from the Ross's relatives and her rather romantic cousin Philip. Before he arrives however, a stranger asks Lesley to deliver a message to Philip which, when she does, she is told not to mention. As war news blackens Lesley hears of a childhood friend Jason Reade, imprisoned aboard a British ship. She hears, too, of Nat's distaste for the flashy Philip. The continental armies begin to fall back and though in the interim it appears as if Jason could be a spy, the truth about Philip and his liaison with the stranger- Benedict Arnold- is discovered at last. Jason and Lesley marry after the Yorktown victory. By the author of Judith of France(1947) The Sword and the Compass (1951), this is substantial fare.
