"If that train robber should send a bullet out this way, you wouldn't think it so funny!" Tommy declared. "He's a mighty suspicious fellow. He wouldn't permit me to wake any of the boys to help get supper."
"Look here," whispered Sandy, "I've got that imitation detective out there waiting for me to tell him whether Chester Wagner is here or not. He says he's hungry, too, and insists that I give him a night lunch. Now I'll tell you what we'll do," the boy continued. "I'll go and steer the detective up against the train robber, and we'll see what he'll do."
Before Tommy could reply, Sandy was away in the darkness, whistling softly to the detective.
"Say," he said, when Katz came lumbering into the edge of the illumination, "the boy isn't there, but I've got good news for you, just the same. The man who went in with my chum is one of the train robbers the cowboys are in search of. There's ten thousand dollars reward offered for him, and all you've got to do is to walk in there, hold a gun to his head, and march him off to Green River. You ought to give me half the reward, though," the boy added, "for you wouldn't have caught him only for me."
"All right," whispered the detective in a shaking voice. "I'll creep back into the shadows and come up from behind. When you go back, point with your hand to where he is. I'll be right there with a gun on him in half a minute!"
"All right," replied Sandy, and the detective disappeared from view.
Then the boy walked back to Tommy's side and explained what sort of circus there would be there in about a minute.
