As the 50th anniversary of the JFK assassination approaches, we are likely to be inundated with material that's been compiled from a variety of sources over those 50 years; conspiracy theories, re-examinations of the published reports, and endless speculation about 'what really happened.' Stephen Hunter, in his Acknowledgements at the end of The Third Bullet, notes that at one time, he considered writing a JFK, 'what really happened' novel, and created his recurring character, Bob Lee Swagger, as the assassin. As it turned out, he abandoned the JFK tale, but kept Bob Lee Swagger, much to the delight of those among us who've grown to appreciate this character (not to mention his knowledgeable-about-guns-ammo-trajectory-science family).
While there appears to be a predictable groan emanating from the general populace, which has, after 50 years, had its fill of alternative history explanations for the event, it's important to remember as you consider whether this novel is worth your time, that the character of Bob Lee Swagger is not 'fresh off the boat.' Those of us who've followed his exploits over a series of novels have come to appreciate his style, his knowledge, and yes, even his eponymous swagger. You are in the hands of a skilled author here, and whatever you may think of his theory, which emanates, unlike other stories of the assassination, from a detailed knowledge about guns, you cannot argue with his craftsmanship in the construction of a compelling tale.
It never occurred to me until I read this book (somewhat of a spoiler alert here; not much, though) that the two bullets that entered Kennedy's body behaved differently. One (which came to be known as the Magic Bullet) charged on through, went on to hit the governor of Texas, and shatter his wrist, and ended up (if memory serves) in his thigh. The other bullet, seen in painful detail on the Zapruder film, blew up in Kennedy's head. How does this happen? How do two bullets, fired presumably from the same gun, act so differently? The question arises from the annals of ammunition technology. Some bullets are designed to explode on contact. Others are not. Two bullets from the same weapon that behave so differently is a little odd. While there's a lot about ammunition technology that might account for it (a sort of Murphy's Law thing, related to a sort of 'shit happens' theory), Hunter's premise is that it's indicative of another weapon, another assassin.
This second assassin (a team, actually, with one shooter) begins to materialize as Swagger starts looking into the assassination. He's prompted to do so by virtue of a request that he finds compelling.
At one point in this story, the narrative is taken over by the Master Planner, who writes in a detailed memoir of the circumstances leading up to, and beyond the immediate gunshot events of November 22, 1963. This Master Planner's 'voice' is first-person narrative, and much livelier than the third-person 'voice,' which tracks Swagger's investigation. You get so you like this guy, even though he's the architect, if not the trigger man, of Kennedy's death.
My strong recommendation in regards to this book (recommended on the book jacket by Lee Child, Michael Connelly, and Vince Flynn, among others) has less to do with the theory that Hunter articulates, than it does with the style in which he articulates it. It's a terrific read, and unless I'm sadly mistaken will do more to bring this moment of history to light again, than any of the academic tomes to which we are likely to be subjected over the next nine months.
