last instant, the attendant started forward with his mouth open to say something, but I didn't wait to hear it. I gunned out into the night, slung into the graveled drive, and headed for the gate. Mallon had had it all his way so far, but maybe it still wasn't too late.... Two sentries, looking miserable in shiny black ponchos, stepped out of the guard hut as I pulled up. One peered in at me, then came to a sloppy position of attention and presented arms. I reached for the gas pedal and the second sentry called something. The first man looked startled, then swung the gun down to cover me. I eased a hand toward my pistol, brought it up fast and fired through the glass. Then the Bentley was roaring off into the dark along the potholed road that led into town. I thought I heard a shot behind me, but I wasn't sure. I took the river road south of town, pounding at reckless speed over the ruined blacktop, gaining on the lights of Mallon's horde paralleling me a mile to the north.

With his new toy, Mallon was dozing his way through the men and buildings that got in his way. I reached the gate, picked my way over fallen wire mesh, then headed for the Primary Site. I couldn't run now. The broken slabs tilted crazily, in no pattern. I slipped, stumbled, but kept my feet. Behind me, headlights threw
