Ken nodded. “And then what?” he asked.

“Leave the rest to me.”

When the two boys arrived in front of Jack’s home, Paul spoke up rather loudly, “I guess I’ll walk down the block and call Nuthin’. I’ll be back in about five minutes.”

“All right,” answered Ken just as loudly. “Jack and I will wait for you.”

Ken entered the yard while Paul walked off straight ahead. Turning in at the end of the street, he set off at a run around the block.

Returning to the same street at the other end, he hovered close to the wall of a building and looked everywhere to detect the hiding place of the spy. Suddenly he caught his breath. He detected a slight movement behind a fence at the other side of the street, several houses below. He crossed to the other side and walked ahead. Sure enough, a man stepped out and came toward him. As they met, Paul greeted, “Hello, Captain Bob.”

The man grunted and was going to pass on, but Paul instantly got into his way. The man stopped, “Huh?” he muttered. “Did you speak to me?”

“I said hello, Captain Bob.”

“Hello yourself. Now let me see, your face seems to be familiar, but I can’t seem to remember your name.”
