At the beginning of the long twilight of a summer evening, Sam McPherson, a tall big-boned boy of thirteen, with brown hair, black eyes, and an amusing little habit of tilting his chin in the air as he walked, came upon the station platform of the little corn-shipping town of Caxton in Iowa. It was a board platform, and the boy walked cautiously, lifting his bare feet and putting them down with extreme deliberateness on the hot, dry, cracked planks. Under one arm he carried a bundle of newspapers. A long black cigar was in his hand. In front of the station he stopped; and Jerry Donlin, the baggage-man, seeing the cigar in his hand, laughed, and slowly drew the side of his face up into a laboured wink.
