L. Frank Baum,
Mary Louise — VIII. A FRIENDLY FOE
(1916)
“ The conductor of the train, as he passed through the car, paused at the rear end and gazed thoughtfully at the little man huddled in the rear seat, who seemed unconscious of his regard. After watching him a while the conductor suddenly turned his head and looked directly at Mary Louise, with a curious expression, as if connecting his two passengers. Then he went on through the train, but the girl's heart was beating high and the little man, while seeming to eye the fleeting landscape through the window, wriggled somewhat uneasily in his seat. ”
