“OK,” Stuyvesant said. “You and Ms. Neagley, on the ground, observing.”

Froelich drove them to Georgetown in her Suburban. They arrived just before ten o’clock. They got out three blocks short of Armstrong’s house and Froelich drove on. It was a cold day, but a watery sun was trying its best. Neagley stood still and glanced around, all four directions.

“Deployment?” she asked.

“Circles, on a three-block radius. You go clockwise and I’ll go counterclockwise. Then you stay south and I’ll stay north. Meet back at the house after he’s gone.”

Neagley nodded and walked away west. Reacher went east into the weak morning sun. He wasn’t especially familiar with Georgetown. Apart from short periods during the previous week spent watching Armstrong’s house he had explored it only once, briefly, just after he left the service. He was familiar with the college feel and the coffee shops and the smart houses. But he didn’t know it like a cop knows his beat. A cop depends on a sense of inappropriateness. What doesn’t fit? What’s out of the ordinary? What’s the wrong type of face or the wrong type of car for the neighborhood? Impossible to answer those questions without long habituation to a place. And maybe impossible to answer them at all in a place like Georgetown. Everybody who lives there comes from somewhere else. They’re there for a reason, to study at the university or to work in the government. It’s a transient place. It has a temporary, shifting population. You graduate, you leave. You get voted out, you go someplace else. You get rich, you move to Chevy Chase. You go broke, you go sleep in a park.

So just about everybody he saw was suspicious. He could have made a case against any of them. Who belonged? An old Porsche with a blown muffler rumbled past him. Oklahoma plates. An unshaven driver. Who was he? A brand new Mercury Sable was parked nose-to-tail with a rusted-out Rabbit. The Sable was red and almost certainly a rental. Who was using it? Some guy just in for the day for a special purpose? He detoured next to it and glanced in through the windows at the rear seat. No overcoat, no hat. No open ream of Georgia-Pacific office paper. No box of latex medical gloves. And who owned the Rabbit? A graduate student? Or some backwoods anarchist with a Hewlett-Packard printer at home?

There were people on the sidewalks. Maybe four or five of them visible at any one time in any one direction. Young, old, white, black, brown. Men, women, young people carrying backpacks full of books. Some of them hurrying, some of them strolling. Some of them obviously on their way to the market, some of them obviously on their way back. Some of them looking like they had no particular place to go. He watched them all in the corner of his eye, but nothing special jumped out at him.

Time to time he checked upper-story windows as he walked. There were a lot of them. It was good rifle territory. A warren of houses, back gates, narrow alleys. But a rifle would be no good against an armored stretch limo. The guy would need an antitank missile for that. Of which there were plenty to choose from. The AT-4 would be favorite. It was a three-foot disposable fiberglass tube that fired a six-and-a-half pound projectile through eleven inches of armor. Then the BASE principle took over. Behind Armor Secondary Effect. The entrance hole stayed small and tight, so the explosive event stayed confined to the interior of the vehicle. Armstrong would be reduced to little floating carbon pieces not much bigger than charred wedding confetti. Reacher glanced up at the windows. He doubted that a limo would have much armor plate in the roof, anyway. He made a mental note to ask Froelich about it. And to ask if she often rode in the same car as her charge.

He turned a corner and came out at the top of Armstrong’s street. Looked up at the high windows again. A mere demonstration wouldn’t require an actual missile. A rifle would be functionally ineffective, but it would make a point. A couple of chips in the limo’s bulletproof glass would serve some kind of notice. A paintball gun would do the trick. A couple of red splatters on the rear window would be a message. But the upper-floor windows were quiet as far as the eye could see. They were clean and neat and draped and closed against the cold. The houses themselves were quiet and calm, serene and prosperous.

There was a small crowd of onlookers watching the Secret Service team erect an awning between Armstrong’s house and the curb. It was like a long narrow white tent. Heavy white canvas, completely opaque. The house end fitted flat against the brick around Armstrong’s front door. The curb end had a radius like a jetway at an airport. It would hug the profile of the limo. The limo’s door would open right inside it. Armstrong would pass from the safety of his house straight into the armored car without ever being visible to an observer.

Reacher walked a circle around the group of curious people. They looked unthreatening. Neighbors, mostly, he guessed. Dressed like they weren’t going far. He moved back up the street and continued the search for open upper-story windows. That would be inappropriate, because of the weather. But there weren’t any. He looked for people loitering. There were plenty of those. There was a block where every second storefront was a coffee shop, and there were people passing time in every one of them. Sipping espresso, reading papers, talking on cell phones, writing in cramped notebooks, playing with electronic organizers.

He picked a coffee shop that gave him a good view south down the street and a marginal view east and west and bought a tall regular, black, and took a table. Sat down to wait and watch. At ten fifty-five a black Suburban came up the street and parked tight against the curb just north of the tent. It was followed by a black Cadillac stretch that parked tight against the tent’s opening. Behind that was a black Town Car. All three vehicles looked very heavy. All three had reinforced window frames and one-way glass. Four agents spilled out of the lead Suburban and took up stations on the sidewalk, two of them north of the house and two of them south. Two Metro Police cruisers snuffled up the street and the first stopped right in the center of the road well ahead of the Secret Service convoy and the second hung back well behind it. They lit up their light bars to hold the traffic. There wasn’t much. A blue Chevy Malibu and a gold Lexus SUV waited to get by. Reacher had seen neither vehicle before. Neither had been out cruising the area. He looked at the tent and tried to guess when Armstrong was passing through it. Impossible. He was still gazing at the house end when he heard the faint thump of an armored door closing and the four agents stepped back to their Suburban and the whole convoy took off. The lead cop car leapt forward and the Suburban and the Cadillac and the Town Car fell in behind it and moved fast up the street. The second police cruiser brought up the rear. All five vehicles turned east right in front of Reacher’s coffee shop. Tires squealed on the pavement. The cars accelerated. He watched them disappear. Then he turned back and watched the small crowd in the street disperse. The whole neighborhood went quiet and still.

They watched the motorcade drive away from a vantage point about eighty yards from where Reacher was sitting. Their surveillance confirmed what they already knew. Professional pride prevented them from writing off his commute to work as actually impossible, but as a viable opportunity it was going to be way down on their list. Way, way down. Right there at the bottom. Which made it all the more fortunate that the transition website offered so many other tempting choices.

They walked a circuitous route through the streets and made it back to their rented red Sable without incident.
