By David Baldacci. Sean King is a former Secret Service agent who allowed his attention to wander for a split second, an error that resulted in the death of the presidential candidate he had been protecting. Michelle Maxwell is a former Secret Service agent who “lost” the politician she was supposed to protect when the politician vanished behind closed doors while comforting a grieving widow. Their destinies converge when Michelle becomes obsessed with Sean’s case, and when Sean needs the help of a new friend to solve crimes that implicate him as the culprit. Professional pride, romantic tension, and common causes bring together King and Maxwell as a crime-solving dynamic duo.
