David Baldacci's suspense thrillers, like Last Man Standing, always find their way to the top of the New York Times best-seller list. Simple Genius follows on the heels of The Hour Game and stars Secret Service agents Sean King and Michelle Maxwell. Scarred and battered, they quickly become ensnared by a dark conspiracy that could have dire ramifications for the free world. A murder occurs at a D.C. think-tank, and King investigates. Maxwell joins him, only to discover that they are being used in a scheme that threatens national security.
