Silver Cross

When her friend is murdered, Tolman rushes to North Carolina to investigate. She finds a vast conspiracy hanging on a letter from Napoleon III to Confederate president Jefferson Davis, pledging French aid to the Confederacy for the "Silver Cross." The letter was lost when confederate spy Rose Greenhow drowned just yards from Confederate soil. Tolman asks history professor Nick Journey for his help, and soon the two are following a treasure map deep into the west Texas desert. Hot on their trail are others desperately trying to cover up the existence of the "Silver Cross", including Ann Gray, a freelance assassin gone rogue, and her former employers, a secretive group known only as the Associates. As horrifying acts of domestic terrorism erupt throughout the country, Journey and Tolman seek an answer to the 150-year-old riddle before it's too late.
