This reflection rendered the girl very uneasy and caused her to watch the fat-nosed man guardedly all through that tedious day. She constantly hoped he would leave the train at some station and thus prove her fears to be groundless, but always he remained in his seat, patiently eyeing the landscape through his window. Late in the afternoon another suspicious circumstance aroused her alarm. 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, Mary Louise now decided he was a detective. She suspected that he had been sent to Beverly, after the other man left, to watch her movements, with the idea that sooner or later she would rejoin her grandfather. Perhaps, had any letter come for her from her mother or Gran'pa Jim, this officer would have seized it and obtained from it the address of the man he was seeking. That would account for their failure to write her; perhaps they were aware of the plot and therefore dared not send her a letter. And now she began wondering what she should do when she got to Dorfield, if the little man also left the train at that station. Such an act on his part would prove that her suspicions were correct, in which case she would lead him straight to her grandfather, whom she would thus deliver into the power of his merciless enemies. No; that would not do, at all. If the man followed her from the train at Dorfield she dared not go to Peter Conant's house. Where, then, COULD she go? Had she possessed sufficient money it might be best to ride past Dorfield and pay her fare to another station; but her funds were practically exhausted. Dorfield was a much bigger town than Beverly; it was quite a large city, indeed; perhaps she could escape the supervision of the detective, in some way, and by outwitting him find herself free to seek the Conant's home. She would try this and circumstances must decide her plan of action. Always there was the chance that she misjudged the little man. As the conductor called the station the train halted and the girl passed the rear seat, where the man had his bare head half out the open window, and descended from the car to the platform. A few others also alighted, to hurry away to the omnibuses or street car or walk to their destinations. Mary Louise stood quite still upon the platform until the train drew out after its brief stop. It was nearly six o'clock in the evening and fast growing dark, yet she distinctly observed the fat-nosed man, who had
