I looked where he had pointed. Creepers and lianas and thick fern-brakes obscured my view. I couldn't see a thing.

"Out there," he said again.

I could see perhaps five yards, no more. It was utterly silent. It was also hot and humid as it always is in the Venusian swamps. My khakis clung to me with sweat.

"I still can't see a thing," I said. He pointed a third time. I stared and saw nothing and was about to say so when something struck the side of my head just above the ear.

I staggered off into the fern-brake and sat down. I was groggy and I didn't know what had hit me. There still wasn't a sound in the jungle. When I brought my hand up to my ear and brought it away again, it was red and wet and glistening with blood. I turned around slowly, stiffly—

Jason Woods Stevenson stood there in the fern-brake. He looked gigantic. He lifted the big Marlin Magnum .375 over his head and brought it down, butt-first. I rolled over and away and the big rifle struck half a foot from my head. Several inches of the rifle were buried in the mud and I had time to stagger to my feet while Mr. Stevenson pulled it clear.

"What's the matter with you?" I roared. "What's the—"

He stood five feet from me. He swung the rifle around and pointed it at my chest.

There wasn't a sound—not a sound. It was like a nightmare....

I used my own rifle to knock his aside as it went off. The Marlin Magnum packs a kick and he stumbled back a step. I went after him and when he pointed his rifle at me again and looked as if he would squeeze the trigger I had no choice. I swung my own rifle like a club and brought it down with savage force on his shoulder.
