"Good!" Mr. Nichols exclaimed. "I am satisfied that you are the sort of man I can use. If you will work secretly with my investigators, I am confident we shall produce results."

"I'll be glad to cooperate in every way I can," the officer promised.

They shook hands to seal the agreement. Jerome Davis turned to leave.

"Thank you for coming here tonight," the detective said as he escorted the officer to the door. "You will receive instructions from me within a short while. A day or two at the latest."

After the door had closed behind the caller, Penny arose from her chair.

"Did you enjoy the interview?" her father asked, smiling.

"It was vastly exciting! I thought surely I'd be seen."

"Mr. Davis was too engrossed in our talk to be very observing."

"I don't wonder that Betty Davis worries about her father. I heard him say that he had been threatened by the Molberg gang."

"Yes, Davis is in an awkward situation. However, he seems to be a man of courage. I can use him."
