"I didn't get a chance to listen. As I was coming up I saw the first man give the second man some money. Then the second man looked up and saw me, and shoving the money into his pocket, he dove across the street and into the crowd. That made me feel sure it was Crabtree, and I ran after him pell-mell. I followed him for about half a block. But the crowd was too much for me, and he got away. I was going to tell a policeman, but then I thought he couldn't do any more than I could, and I made up my mind I'd wait for you."

"What became of the other fellow—the man with the pointed chin?"

"I don't know. He went off somewhere while I was after Crabtree—if it was Crabtree," answered Sam.

"Show me which way Crabtree went," said Dick, and the brothers walked in the direction the fugitive had taken. But, though they spent over an hour in looking for the man, not a trace of him could be found.

"Well, this proves one thing anyway," said Dick, as he and Sam started on the return to the hotel. "Crabtree is in league with Pelter, Japson & Company. If he wasn't, he wouldn't show himself so close to their offices."

"Just what I think," returned his brother. "And another thing, Dick; I think that man with the pointed chin is in with the brokers, too."

"More than likely. For all we know he may be one of the firm!" went on Dick suddenly. "Wait, I've got an idea. I think I'll go back to those offices."

"And see if the man with the pointed chin is there?"

"Yes."

"All right. Want me to go back, too?"
