For almost two decades, through the War of 1812, James Wilkinson was the senior general in the United States Army. Amazingly, he was also Agent 13 in the Spanish secret service at a time when Spain's empire dominated North America. Wilkinson's audacious career as a double agent is all the more remarkable because it was an open secret, circulated regularly in newspapers and pamphlets. His saga illuminates just how fragile and vulnerable the young republic was: No fewer than our first four presidents turned a blind eye to his treachery and gambled that the mercurial general would never betray the army itself and use it too overthrow the nascent union—a faith that was ultimately rewarded.

From Publishers WeeklyAnyone with a taste for charming, talented, complex, troubled, duplicitous and needy historical figures will savor this book. A Revolutionary War general at age 20, James Wilkinson (1757–1825), whom few now have heard of, knew everyone of consequence in the early nation, from Washington on down. But he squandered his gifts in repeated and apparently uncontrollable double dealing, betrayals (he spied for Spain), conspiracies and dishonesty in the decades following the war. Wilkinson seemed to pop up everywhere, always trying to make a deal and feather his nest. To those ends, he would as soon turn on those whom he had pledged to help as be traitor to the army he served. The only man he remained true to was Jefferson, who in the end spurned him. No one trusted him, as no one should have. Linklater (Measuring America) skillfully captures this sociopathic rogue who, for all his defects, still commands attention from everyone trying to understand the 50 years after 1775. His charisma reaches across two centuries to perplex and fascinate any reader of this fast-paced and fully researched work.
