CHAPTER VIII A FRIENDLY FOE It required two days and a night to go by rail from Beverly to Dorfield and as Mary Louise had passed a sleepless night at the school she decided to purchase a berth on the sleeper. That made a big hole in her surplus of eight dollars and she also found her meals in the dining car quite expensive, so that by the time she left the train at Dorfield her finances would be reduced to the sum of a dollar and twenty cents. That would not have disturbed her, knowing that thereafter she would be with Gran'pa Jim, except for one circumstance. The little man with the fat nose, who had taken the train at Beverly, was still on board. All the other passengers who had been on the train at that time had one by one left it and been replaced by others, for the route lay through several large cities where many alighted and others came aboard.

"If this little man," she mused, glancing at his blank, inexpressive features, "happens to be a detective, and knows who I am, he may think I will lead him directly to Colonel Weatherby, whom he may then arrest. Gran'pa Jim is innocent, of course, but I know he doesn't wish to be arrested, because he left Beverly suddenly to avoid it. And," she added with a sudden feinting of the heart, "if this suspicion is true I am actually falling into the trap and leading an officer to my grandfather's retreat." This reflection rendered the girl very uneasy and caused her to watch
