Former secret service agents turned private investigators Sean King and Michelle Maxwell have seen their lives splinter around them. Michelle lies unconscious in a hospital bed after a night of suicidal violence. And Sean is forced to take on an investigation into the suspicious death of a scientist just inside the CIA's razor-wire fence near Williamsburg, Virginia.

Soon he is uncovering layer after layer of disinformation that shields a world filled with elite mathematicians, physicists, war heroes, spies, and deadly field agents. Amid more murder, a seemingly autistic girl's extraordinary genius, and powerful breakthrough in the realm of classified codes, Sean soon learns enough to put his life at risk. Now more than ever, he needs Michelle to help him catch a killer, save an innocent life, and solve a terrifying mystery that threatens the very soul of the nation.

From Michelle's couragous struggle to defeat her long-buried personal demons to a centuries-old secret that surfaces in the heat of the action, Simple Genius pulses with stunning, high-intensity suspense. The heroes of Split Second and Hour Game, David Baldacci's #1 New York Times bestsellers, are back - as you've never seen them before.
