The chief picked up the fake five dollar bill that Jack had thrown on the desk and examined it carefully. He rose and walked to the door and called to his secretary. “Tell Jim Spencer I want to see him right away.”

He returned to his swivel chair and said to the boys, “Now fellows, I am not doubting your story; on the contrary, I think that you may be telling the truth. But you understand that I have to question you closely.” He paused and the boys looked relieved; they even smiled happily. “In the meanwhile, I do wish you would tell me the whole story, from beginning to end, how you happened to discover this gang and all that.”

Paul looked at his friends and they nodded to him. Jack said, “Go on, Paul, tell him. But it will take a long time, though, Chief.”

The Chief of Police nodded. “That’s all right. I’m a good listener.”

Just then a tall, husky man entered the office and said, “You called for me, Chief?”

“Yes. Take a look at this.” And the chief gave Jim Spencer the counterfeit bill.

The detective quickly and expertly glanced at the bill and announced, “It’s fake, all right, Chief. Very clever work, though. Most likely the work of Moonshine Charlie.”

“You know what these boys are telling me, Jim?” asked the Chief. The detective shook his head and Bates continued, “They say that they have located the gang, have been down in their hangout and all they want now, I guess, is for us to step in and clean the gang up, isn’t that so, fellows?”

“That’s right,” cried Jack. “And you had better hurry, too.”

“Very interesting,” commented Jim Spencer. “How did they happen to discover it all?”
