The Last Chameleon — James North

Dead Drop. Less than two years after the assassination of her husband, Caroline Dupre joins Vanguard-an ultra-secret organization set up after the Cold War to counter the rise in non-conventional global threats. Soon, she learns that she is the only operative suited for a crucial part of a mission to stop a plan hatched by a former Bulgarian intelligence officer-the Chameleon-to pass nuclear material to a rogue government seeking to develop nuclear weapons. Time is short and the Chameleon is removing anyone and everything threatening his plan. Can Caroline survive his wrath? Can she stop him? James North is a former U.S. Navy intelligence officer, a former consultant to the U.S. Government, political analyst, and university lecturer. He currently lives in Europe."
