Two other elements I should mention here.

As discreetly as possible, I should point out that on this trip I was not alone. I was with a woman who would later become my wife, and the theme of a man being drawn out of disappointment and solitude and despair by the love of a good woman was something I truly felt and that filled me with hope and joy and pleasures I never thought I’d have. I tried to get that into the book too, in the relationship between Bob and his savior, Julie.

Now, embarrassed, I leave that paragraph to stand alone and move on to another love: rifles. I wanted this to be a rifle book. I was-and always have been, as readers surely all know by now-a gun crank. Gun nut? Is that what you want to call it? Gun buff, gun guy, gunnie, gunner, shooter, Mr. Saturday Night Special, something or other. Well, call it what you wish, but the truth is, the firearm has always, always been a reliable provocateur of my imagination. I even remember when it started. I think it was 1954; I was staying up late, illegally, watching Dragnet. My father was out doing something stupid and ugly and drunken, no doubt. My mother was fretting and feeling sorry for herself, and I was watching Joe Friday and Ben Smith hunt down some kind of killer in the San Fernando Valley. Or maybe it wasn’t the valley; I don’t know: some tract house in a dreary far-flung LA burg. But I do remember when Joe and Ben located the suspect, and under Joe’s instructions, Ben called it in to HQ. Joe told Ben, “And tell ’em to bring plenty of.45s for the machine guns. It looks like he wants to go all the way.”

He did want to go all the way. He came out of the house pistols blazing, there to run into Sergeant Friday, that icon of ’50s righteousness, with his Thompson submachine gun, and Joe spoke for civilization when he blew the guy out of his socks. In any event, the next day I sat down with a piece of paper and a pencil and applied myself and in an hour had drawn a respectable silhouette of a “Fifty Caliber Thompson Submachinegun,” as I labeled it, making it, at.50, bigger than Joe’s! At that point, firearms entered my imagination formally, and I began to read about them, to notice them on TV and in movies, to dream about them-and to draw them. All my schoolbooks were inscribed with detailed side views, copiously labeled: “Thompson submachine gun M-1928,.45 caliber” or “M-1 Carbine” or “.45 automatic.” I conspicuously sought out cap guns that were accurate in their representation, and if I found a cap gun that seemed accurate but whose typology I did not recognize, I tracked it down. In 1956, at the age of ten, I became a subscriber to Guns magazine and drank up every word.

Of course today such behavior would get me a daily Ritalin cocktail (or stronger), a permanent appointment with a shrink, and entry onto the school district’s watch list, but nobody then thought it was particularly weird, and I must say this: it was fun. God, it was a pleasure to lose myself among the sweeps and curves and struts and screws of the various creations, to puzzle over the subtlety of line. It was so strange. In time I became a passingly good draftsman of the firearm from the 90-degree perspective, and even occasionally tilted them to 45 degrees, to suggest weight and solidity. I could draw anything except-true to this day-a Colt Peacemaker. For some reason, Colonel Colt’s genius eluded me: I could never capture the nuance of the curves, the subtle orchestration of the variation between the grip curve, the receiver curve, and the trigger guard curve.

Regardless, that love of guns stayed with me, except for a brief, delusional period in the early ’70s when I called myself a liberal and held myself superior to gun culture. But it always beckoned and I always knew it was my true faith, and one of the things that let me progress from wanting to write to writing was acknowledgment of guns’ deep import to me and their power to stir my imagination to its most expressive. Still, I really had never shot much and hadn’t actually bought a gun until just a few years previous, when I was working on The Day Before Midnight, a gun-rich commando novel.

I knew that to make a sniper real I had to make the rifle real, and to make the rifle real I had to shoot it, clean it, take it apart, carry it, make it a part of my life. So I bought as near as I could get to a Marine sniper rifle. It was a Remington 700 in.308, the police model with a heavy bull barrel, plain-Jane it its bluntness and simplicity, with no aspirations toward style or beauty. (This was also a part of my conspicuous separation from Carlos Hathcock, as he’d done all his shooting in Vietnam with a Winchester Model 70.) I mounted a Leupold 10X scope on it, as had the Marines in Vietnam (though theirs were Redfields, but still 10Xs). And I went out to the Marriottsville Road shooting range about five miles north of my house in Columbia, and I shot… and I shot… and I shot. I learned immediately that everything I’d seen in the movies was fake. I learned, first of all, how hard it was. I learned how subtle it was, how you had to find the strength and yet the suppleness to turn your body to structure, to be tight in some places and loose in others, and you had to take command of your breathing. You had to master your heart and mind, in other words, and if you couldn’t, you’d never be any good at it.

I was never any good at it, though in time I became close to adequate. However, the excitement of learning somehow alchemized my writing into something truer. I was aware that the process had never been accurately portrayed in a book, and I thought if I could get that right, I’d have something different, at least.

Finally, there was courage. Bob, I knew, would be brave. He would be one of those rare men (wholly, wildly unlike me, I hasten to add) who could face enemy fire stoically, figure it out as a problem in higher calculus, and work swiftly and efficiently to counter it. It wasn’t that he wasn’t afraid; it was that he had learned to deal with his fear, or that he had a motive so overpowering that it vanquished his fear. And what would that motive be?

I studied the biographies of war heroes to determine what made them so brave. In the case of officers (that is, leaders), it was a belief in cause and system, a fear of not letting others down, a sense of responsibility. But that’s not what would drive a sniper. He’s alone, on his own, out there in Indian country. No one knows if he’s brave or not; he really answers only to himself. What drives him? I had to find out, because I was determined to create the whole man, and I didn’t want to just declare him brave and let it go at that, as happens routinely in B movies and novels.

Ultimately, I hit upon another creature of tremendous will and attainment, who was nevertheless thorny, difficult, even repulsive. I hit upon Tyrus Raymond Cobb. It’s part of my attraction to difficult men that I like Ty Cobb. Yes, I know: racist, sexist, violent, outsider to the end, vicious, vengeful, tough as brass bushings, relentless, unpleasant, ultimately spurned by everyone. But his backstory is very interesting. When he was nineteen years old and had just signed his first professional-baseball contract, his mother murdered his father in her bedroom with a shotgun. Her lover was in bed with her. Ty Cobb loved his father, a prominent Georgia lawyer, seen by all as a fair, kind, brilliant, just man. He felt immensely cheated by the fact that his father never saw him play ball professionally, and he was shattered at the squalid circumstances of his father’s death, so small in comparison to the attainments of the man himself. Nevertheless, he paid for his mother’s defense and saw her get off as not guilty, pleading that she thought it was an intruder at the window.

I decided to give Bob a similar dynamic-a brilliant father, snatched from him early in squalid circumstances that were no match for the accomplishments of the man, so that the haunted son would miss his father greatly and spend his life trying to live up to the man’s brilliance. He would be a man who idealized his father, never having learned that his father was just a man, with his own foibles and flaws.
