Six: A Novel of Domestic Terrorism

He escaped from St. Elizabeths. He found his crew. And now he's coming for the President - and the FBI agent who put him away.
Robert Smithson should be locked up forever. Instead, he's free - and more dangerous than before. Surrounded by a cell of anti-government extremists who share his hatred and his ambition, Smithson has acquired drones and a bioweapon designed for one mission: a mass-casualty strike on Camp David, targeting the President and the entire senior leadership of the U.S. government.
FBI Special Agent Bill Peterson knows Smithson better than anyone. He also knows Smithson hasn't forgotten him. The question isn't just whether Peterson can stop the attack - it's whether Smithson will come for Peterson's family before he gets the chance.
Cat and mouse. But after two rounds, both of them know: this is the final game.
