their footsteps as they headed toward Jefferson Drive.
Without losing another instant Bourne checked the bypass he'd made on the alarm system. So far it showed everything as normal. He pushed out the door. Night wind struck his face as he saw two agents, sidearms drawn, hurrying up the granite stairs. He had just enough time to register the oddness of the guns before he ducked back inside, went directly to the fire call box.
They came through the door. The leading one got a face full of fire-smothering foam. Bourne ducked a wild shot from the second agent. There was virtually no noise, but something pinged off the Tennessee white marble wall near his shoulder, then clattered to the floor. He hurled the fire extinguisher at the shooter. It struck him on the temple and he went down. Bourne broke the call box's glass, pulled hard on the red metal handle. Instantly the fire alarm sounded, piercing every corner of the gallery.
Out the door, Bourne ran diagonally down the steps, heading west, directly for 12th Street, SW. He expected to find more agents at the southwest corner of the building, but as he turned off Independence Avenue onto 12th Street he encountered a flood of people drawn to the building by the alarm. Already the sirens of fire trucks could be heard floating through the rising chatter of the crowd.
He hurried along the street toward the entrance down to the Smithsonian Metro stop. As he did so, he accessed the Internet through his cell. It took longer than he would have liked, but at last he pressed the FAVORITES icon, was returned to the Metro site. Navigating to the Smithsonian station, he scrolled down to the hyperlink to the next train arrival, which was refreshed every thirty seconds. Three minutes to the Orange line 6 train to Vienna/Fairfax. Quickly he composed a text mail "FB," sent it to a number he'd prearranged with Professor Specter.
The Metro entrance, clogged with people stopped on the stairs to watch the unfolding scenario, was a mere fifty yards away. Bourne heard police sirens now, saw a number of unmarked cars heading down 12th Street toward Jefferson. They turned east when they got to the junction-all except one, which headed due south.
Bourne tried to run, but he was hampered by the press of people. He broke free, into a small area blessedly empty of the gigantic jostle, when the driver's window of a cruising car slid down. A burly man with a grim face and a nearly bald head aimed another one of those strange-looking handguns at him.
Bourne twisted, putting one of the Metro entrance posts between himself and the gunman. He heard nothing, no sound at all-just as he hadn't back inside the Freer-and something bit into his left calf. He looked down, saw the metal of a mini dart lying on the street. It had grazed him, but that was all. With a controlled swing, Bourne went around the post, down the stairs, pushing his way through the gawkers into the Metro. He had just under two minutes to make the Orange 6 to Vienna. The next train didn't leave for four minutes after that-too much time in the platform, waiting for the NSA agents to find him. He had to make the first train.
He bought his ticket, went through. The crowds thinned and thickened like waves rushing to shore. He began to sweat. His left foot slipped. Rebalancing himself, he guessed that whatever was in that mini dart must be having an effect despite only grazing him. Looking up at the electronic signs, he had to work to focus in order to find the correct platform. He kept pushing forward, not trusting himself to rest, though part of him seemed hell-bent on doing just that. Sit down, close your eyes, sink into sleep. Turning to a vending machine, he fished in his pockets for change, bought every chocolate bar he could. Then he entered the line for the escalator.
Partway down he stumbled, missed the riser, crashed into the couple ahead of him. He'd blacked out for an instant. Gaining the platform, he felt both shaky and sluggish. The concrete-paneled ceiling arched overhead, deadening the sounds of the hundreds crowding the platform.
Less than a minute to go. He could feel the vibration of the oncoming train, the wind it pushed ahead of it.
He'd gobbled down one chocolate bar and was starting on the second when the train pulled into the station. He stepped in,
