people in her office again. She used abbreviations and a torrent of jargon he couldn't follow. Finished the call and closed her phone.
"We'll bring a Metro traffic chopper in," she said. "Keep it low enough to be obvious. He'll have to pass the Armenian Embassy, so we'll put some extra cops there. They'll blend in. I'll follow him in the car on D Street fifty yards behind. I want you out ahead of him with your eyes wide open."
"When are we doing this?"
"Within ten minutes. Go up the street and left."
"OK," he said. She restarted the car and rolled forward so he could step onto the sidewalk clear of the tent. He got out and zipped his jacket and walked away into the cold. Up First Street and left onto C Street. There was traffic on Delaware Avenue ahead of him and beyond it he could see Capitol Plaza. There were low bare trees and open brown lawns. Paths made from crushed sandstone. A fountain in the center. A pool to the right. To the left and farther on, some kind of an obelisk memorial to somebody.
He dodged cars and ran across Delaware. Walked on into the plaza. Grit crunched under his shoes. It was very cold. His soles were thin. It felt like there were ice crystals mixed in with the crushed stone underfoot. He stopped just short of the fountain. Looked around. Perimeters were good. To the north was open ground and then a semicircle of state flags and some other monument and the bulk of Union Station. To the south was nothing except for the Capitol Building itself far away across Constitution Avenue. Ahead to the west was a building he assumed was the Department of Labor. He looped around the fountain with his eyes focused on the middle distance and saw nothing that worried him. Poor cover, no close windows. There were people in the park, but no assassin hangs around all day just in case somebody's schedule changes unexpectedly.
He walked on. C Street restarted on the far side of the plaza, just about opposite the obelisk. It was more of an upright slab, really. There was a sign pointing toward it: Taft Memorial. C Street crossed New Jersey Avenue and then Louisiana Avenue. There were crosswalks. Fast traffic. Armstrong was going to spend some time standing still waiting for lights. The Armenian Embassy was ahead on the left. A police cruiser was pulling up in front of it. It parked on the curb and four cops got out. He heard a distant helicopter. Turned around and saw it low in the north and west, skirting the prohibited airspace around the White House. The Department of Labor was dead ahead. There were plenty of convenient side doors.
He crossed C Street to the north sidewalk. Strolled back fifty yards to where he could see into the plaza. Waited. The helicopter was stationary in the air, low enough to be obvious, high enough not to be deafening. He saw Froelich's Suburban come around the corner, tiny in the distance. It pulled over and waited at the curb. He watched people. Most of them were hurrying. It was too cold for loitering. He saw a group of men way on the far side of the fountain. Six guys in dark overcoats surrounded a seventh in a khaki raincoat. They walked in the center of the sandstone path. The two agents on point were alert. The others crowded tight, like a moving huddle. They passed the fountain and headed for New Jersey Avenue. Waited at the light. Armstrong was bareheaded. The wind blew his hair. Cars streamed past. Nobody paid attention. Drivers and pedestrians occupied different worlds, based on relative time and space. Froelich kept her distance. Her Suburban idled along in the gutter fifty yards back. The light changed and Armstrong and his team walked on. So far, so good. The operation was working well.
Then it wasn't.
First the wind pushed the police helicopter slightly off station. Then Armstrong and his team were halfway across the narrow triangular spit of land between New Jersey Avenue and Louisiana Avenue when a lone pedestrian did a perfect double take from ten yards away. He was a middle-aged guy, lean from neglect, bearded, long-haired, unkempt. He was wearing a belted raincoat greasy with age. He stood completely still for a split second and then launched himself toward Armstrong with his legs taking long bouncing strides and his arms windmilling uselessly and his mouth
