“I think we’ve run over some one,” announced a fussy little man with a monocle and a flower in his buttonhole.

With a warning toot of the whistle, the train began to move slowly forward. It went a few feet, apparently hit something solid, and stopped with a violent jar.

“Oh, my goodness!” wailed a woman who was clearly the wife of the fussy little man. “Won’t some one please go and find out what the matter is?”

Betty looked toward the car door and saw Bob pushing his way toward her.


CHAPTER III

WHAT BOB HEARD

When Bob entered the smoking-car he saw the two men he had pointed out to Betty seated near the door at the further end of the car. The boy wondered for the first time what he could do that would offer an excuse for his presence in the car, for of course he had never smoked. However, walking slowly down the aisle he saw several men deep in their newspapers and not even pretending to smoke. No one paid the slightest attention to him. Bob took the seat directly behind the two men in gray, and, pulling a Chicago paper from his pocket, bought that morning on the train, buried himself behind it.

The noise made by the train had evidently lulled caution, or else the suspected sharpers did not care if their plans were overheard. Their two heads were very close together, and they were talking earnestly, their harsh voices clearly audible to any one who sat behind them.
