Who really did kill JFK? Fifty years and multiple official reports later, there are still those who doubt that Lee Harvey Oswald acted alone. In The Third Bullet, retired Vietnam sniper Bob Lee Swagger tackles the granddaddy of all conspiracy theories. Using facts from the Warren Commission and his own extensive knowledge of ballistics, Swagger constructs a complicated but plausible theory of what might have happened if a shadowy rogue agent who wanted Kennedy dead used Oswald as the fall guy. The unforgettable Swagger, older and more cerebral than he was in his first appearance in Point of Impact (1992), still has what it takes in his eighth outing as an action hero. Have yet to make Swagger’s acquaintance? He is a younger (though not by much) more polite version of Clint Eastwood in Gran Torino. Want more thrillers focusing on the Kennedy assassination?
