Never Say No to a Killer — Clifton Adams

THE ROCK WAS about the size of a man's head. A beautiful rock, about twenty pounds of it, and somehow I had to get over to it. The minute I saw it I knew that rock was just the thing I needed. This is going to take some doing, I thought, but I have to get my hands on that rock. Gorgan yelled, "Get the lead out, Surratt! This ain't no goddamn picnic!" Gorgan was one of the prison guards, a red-faced, hairy-armed anthropoid, sadist by instinct, moron by breeding. His lips curled in a grin and he lifted his Winchester 30-30 and pointed it straight at my chest. There was nothing in the world he would like better than an excuse to kill me. He had had his eye on me for a long time. You sonofabitch, I thought, if you knew what was good for you, you would pull that trigger right now, because five minutes from now it's going to be too late!
