"They've spotted the trail," I said. I jumped up and ran down the slope, trying to breathe deep, in for four strides, out for four. A man could run for a long time if he didn't get winded. Stones bruised my bare feet.

I angled over toward the highway, with some idea of making better time. Gaston was beside me.

"Nix," he said, puffing hard. "Them bunnies got a machine."

For a moment I didn't know what he meant; then I heard the sound of an engine starting up, and headlights lanced into the darkness, beams aimed at the distant tree-tops as the car headed up the slope of the approach to the bridge from the other side. We had only a few seconds before the car would slant down on this side, and illuminate the road and a wide strip on either side; we'd be spotlighted.

Ahead, I saw a fence, just a glint from a wire. That finished it; we were stopped. I slid to a halt. Then I saw that the fence lined a cross road, joining the road we were paralleling twenty feet away. Maybe a culvert ... I dived for shelter.

A corrugated steel pipe eighteen inches in diameter ran beside the main road where the other joined it. I scrambled over pebbles and twigs and into the mouth. The sounds I made echoed hollowly inside. I kept going to the far end, Gaston wheezing behind me. I stopped and looked over my shoulder. Gaston had backed in and lay a few feet inside his end. The glow of the headlights gave me a glimpse of a heavy automatic in his hand.

"Good boy," I hissed. "Don't shoot unless you have to."

The lights of the car flickered over trees, highlighting rocks. Through the open end of the pipe I saw a rabbit sitting up in the glare, a few feet away. He turned and bounded off.

The car came slowly along, passed, moved on down the road. I breathed a little easier.

I was on the point of turning to say something to Gaston when a small stone rolled down into the ditch before me. I stiffened. A faint scuff of shoes on gravel, another stone dislodged—and then a flashlight beam darted across the gulley, played on the grass opposite, came to rest on the open end of the drain pipe. I held my breath. Then the steps came nearer, and the light probed, found my shoulder. There was a frozen instant of silence, then the sharp slap of the slug-gun hitting my palm. I caught a glimpse of the car a hundred feet away now, still edging along, heard a sharp intake of breath as the man with the light readied a shout. I pointed the gun to the right of the flash and the recoil slammed my arm back. The flashlight skidded across the rocky ground and went out as the man's body crashed heavily and lay still. I groped for the man's feet, hauled him back toward the pipe.
