An inch over six feet with the thick, muscular build of the undersized linebacker he had once been in college, Knox was in his fifties with thinning hair that he still had barber-shop cut and then slicked back. He also possessed a pair of pale green eyes that were the human equivalent of an MRI: they missed nothing. He gripped the wheel of the Rover with long fingers that had pulled just about every trigger there was while in service to his country. From his secluded, forested neighborhood he turned on to Chain Bridge Road in McLean, Virginia. The traffic would still be heavy on the Beltway this time of morning. Actually, there was really no longer a time when the asphalt noose around the capital city’s neck wasn’t strangled with cars. He pointed his SUV toward the District and backtracked his way to eastern Maryland from there. Eventually he smelled the sea, and with it he envisioned the murder scene. All in a day’s work.

Three hours later he was walking around the truck as fat raindrops pelted down. Carter Gray still sat in his seat-belt harness, his head destroyed and his life ended by what appeared to be a long-range rifle round, although the postmortem would confirm that. While police, FBI and forensic teams buzzed everywhere like bluebottle flies, looking for some place to land and do their business, Joe Knox squatted in front of the white grave marker and small American flag planted in front of it by the side of the road. It was on a curve. The motorcade would have slowed here. A curious Gray had obviously seen these two items and rolled down his window—a fatal mistake.

Grave marker and American flag. Just like at Arlington National. An interesting and perhaps telling choice.

The fact that the windows rolled down showed Knox that the vehicle wasn’t armored. Such vehicles’ windows were phone-book thick and did not move. Gray had made his second mistake there.

Should’ve asked for the armor, Carter. You were important enough.

This wasn’t baseball, Knox knew. In his business, it never took more than two strikes to finish you.

Knox looked off into the distance, tracing in his mind the trajectory of the lethal round. None of the protection detail had seen any sign of a shooter, so he had to cast the potential flight path out farther where the optic and muzzle signatures would be nearly invisible to the naked eye.

Thousand yards? Fifteen hundred? To a target inside a vehicle revealed only through a barely two-by-two-foot opening in the dark and drizzle. And planted the bullet right in the brain.

Remarkable shot any way you look at it. No luck there. A pro.

Revealing again.
