He reached for the dead man's arm and dragged him over. Seconds remained. He yanked off the dead man's tawny coat and grabbed the gray cap, conscious of baleful eyes upon him from shoppers cowering near the Western Union. This was no time for delicacy. Now he shrugged into the roomy overcoat, pulled the cap down hard on his head. If he was to remain alive, he would have to resist the urge to dart toward the second-level escalators like a jackrabbit: he had gone hunting enough to know that anything that moved too abruptly was likely to be shot by an itchy fingered gunman. Instead, he clambered slowly to his feet, hunched, staggering, weaving like an old man who had lost blood. He was now visible and supremely vulnerable: the ruse had to last just long enough to get him to the escalator. Maybe ten seconds. So long as Cavanaugh thought he was a wounded bystander, he wouldn't waste another bullet on him.

Ben's heart was hammering in his chest, his every instinct screaming at him to break into a sprint. Not yet. Hunched over, shoulders rounded, he staggered on with an unsteady gait, his strides as long as he could make them without exciting suspicion. Five seconds. Four seconds. Three seconds.

At the escalator, which had emptied out, abandoned by the terrified pedestrians, the man in the bloodied camel-hair overcoat seemed to crumple face forward, before the movement of the stairs took him out of view.

Now!

Inaction had been as strenuous as exertion, and, every nerve in his body twitching, Ben had broken his fall with his hands. As quietly as he could, he raced down the remaining stairs.

He heard a bellow of frustration from upstairs: Cavanaugh would now be after him. Every second had to count.

Ben put on another burst of speed, but the second below-ground level of the arcade was a virtual maze. There was no straight route of egress to the other side of the Bahnhofplatz, just a succession of byways, the wider walkways punctuated with kiosks of wood and glass that sold cellular phones, cigars, watches, posters. To a dilatory shopper, they were islands of interest--to him, an obstacle course.

Still, they reduced the number of sight lines. They lessened the chance of the long-distance kill. And so they bought him time. Perhaps enough time for Ben to secure the one thing he had on his mind: a shield.

He ran past a blur of boutiques: Foto Video Ganz, Restseller Buchhandlung, Presensende Stickler, Microspot. Kinderboutique, with its window crammed with furry stuffed animals, the display framed by green-and-gold-painted wood with an incised ivy pattern. There was the chrome and plastic of a Swisscom outlet . . . All of them festively plying their goods and services, all utterly worthless to him. Then, straight ahead, to his right, next to a Credit Suisse/Volksbank branch office, he spotted a luggage store. He looked through the window, heaped high with soft-sided leather suitcases--no good. The item he was after was inside: a large, brushed-steel briefcase. No doubt the gleaming steel cladding was as much cosmetic as functional, but it would serve. It would have to. As Ben darted in the store, grabbed the article, and ran out, he noticed that the proprietor, pale and sweating, was jabbering hysterically in Schweitzerdeutsch on the telephone. No one bothered to run after Ben; word of the insanity had already spread.

Ben had gained a shield; he had also lost precious time. Even as he sprang out of the luggage store, he saw its display window transformed into an oddly beautiful spiderweb in the instant before it disintegrated into shards. Cavanaugh was close, so close Ben didn't dare look around to try to locate his position. Instead, Ben charged forward into a crowd of shoppers emerging from Franscati, a large department store at one end of the cruciform plaza. Holding up the briefcase, Ben lunged forward, tripping on someone's leg, regaining his footing with difficulty, losing a few precious moments.
