The lost order

The Knights of the Golden Circle was the largest and most dangerous clandestine organization in American history. It amassed billions in stolen gold and silver, all buried in hidden caches across the United States. Since 1865 treasure hunters have searched, but little of that immense wealth has ever been found. Now, 160 years later, two factions of what remains of the Knights of the Golden Circle want that lost treasure - one to spend it for their own ends, the other to preserve it. Thrust into this battle is former Justice Department agent Cotton Malone, whose connection to the knights is far deeper than he ever imagined. At the centre is the Smithsonian Institution - linked to the knights, its treasure, and Malone himself through an ancestor, a Confederate spy named Angus 'Cotton' Adams, whose story holds the key to everything.
