When a prominent conservative politician is killed inside his lakeside cabin, authorities have no suspect in sight. And two more seemingly different deaths might be linked to the same murderer. From a quiet D.C. suburb to the corridors of power to a deserted island hideaway in Maine, Will, his CIA director wife, Kate, and the FBI will track their man, set a trap-and await the most dangerous kind of quarry, a killer with a cause to die for.
