“The old man and the Mex were dead at the fall, and just swung and spun slowly. But young Tetley didn’t cut. His horse just walked out from under, letting Martin slide off and dangle, choking to death, squirming up and down like an impaled worm, his face bursting with compressed blood. Gerald didn’t move even then, but stood there shaking all over and looking up at Martin fighting the rope.”
