"But I'm going to interest you in just about one minute!" declared Katz. "The boy who stole my property and left your camp in the night is likely to return there at any time. We want that boy. Will you help us get him? If you don't, you're likely to get into trouble yourselves."

"I guess there isn't much chance of his coming back to us!" Sandy answered. "I guess you know that yourself."

"You know who he is?" ask the detective.

"We've been told," was the reply, "that he is the son of the man you're hunting for, but we don't believe it."

"Well, we've made up our minds that he is," Katz went on, "and we've also made up our minds to watch your camp until the boy shows up again. I'll teach him to steal my badge of authority!"

"When you catch him," Sandy requested, "just let us know. We want to see him ourselves. Will you do that?"

"I guess you'll see him before we do," replied Katz, gruffly. "And now, if you don't mind," the detective went on, "I'll just go over to the camp with you and see what the other boys say about him. And while I'm there, you might make me a couple of cups of coffee. I'm a long distance from my camp and quite hungry."

Notwithstanding the impudence of the request, the boy consented to the arrangement and the two were starting away together when the sound of approaching footsteps was heard.

"Gee whiz!" exclaimed Sandy. "This deserted country seems to me about like the corner of State and Madison streets tonight. There's always some one walking around in the dark."

"Suppose we wait and see who it is," suggested the detective.
