Fargo went to Argentina for two reasons. The first was money – $20,000 – because he never sells his gun without getting paid in advance. Professional interest was the second reason; in his time, Fargo had picked up the tricks of his deadly trade by fighting Apaches, comancheros, Philippine insurectos, among others, but he had never tangled with a bunch of bandit gauchos, the meanest breed of men in South America. This particular gang was threatening the richest breeder of prize black bulls south of the Rio Grande. Fargo's job was to put them to bed with a shovel. A lot of good men had died trying, but Fargo was better than good. He was the best corpse-maker in the business.
