“And if you will do that, Mr. Brown, you will make very good money by it,” Andy heard one of the strange men say. He spoke with a strong German accent.

“You will make far more money that way than you ever did in your business,” added the other stranger.

“Yes, but I’ll be running a big risk,” Mr. Brown replied. “Those things are getting more dangerous every day.”

“Say, Pop, why don’t you go up and see Mr. Martell about this?” put in the son.

“Yes, I think we ought to go up and see Nelson Martell,” answered Mr. Brown.

“I have already seen him,” said one of the strangers.

“Well, it won’t do any harm to talk it over again,” returned Slogwell Brown. “Come on; his offices are up on the fifth floor.”

The party of four turned, and as they did so Andy raised his hand and made a quick motion to the other boys to get out of sight. Then, as Slugger Brown and the men passed him, he turned quickly and, bending down, pretended to fix the lace of his shoe. Thus he was passed without being recognized. A few seconds later the four were in the elevator, going up.

“Why did you motion for us to get out of the way?” demanded Jack, as soon as Andy rejoined the others.

“Because I didn’t want Slugger and his father and those other men to see you,” was the quick reply. “Do you know what I think?”
