“Where are you going?” the son asked.

“Right up to the school to make the colonel pay dearly for this outrage!” shouted Melvin Gates, entering the house.

Meanwhile the three were on their way to the school, talking over their lucky escape.

“Let’s take the back streets, fellows,” Don advised. “There was quite an uproar at Gates’ house and we don’t want to meet up with any police who might be suspicious. Of course we could explain things to the chief but the thing we want to do is to get back to the school as fast as we can.”

“OK,” agreed Terry. “I guess we had better get into our overcoats, Jim. We’re pretty heated up and we don’t want to catch cold.”

“No, we don’t,” said Jim. “Here, you hold the cup, Don.”

When they had put on their coats Terry chuckled. “I want to compliment you on being a huge success as a sky rocket, Don! The way you shot down out of that tree onto that fellow’s shoulders was a treat!”

“I couldn’t have done it if you and Jim hadn’t been so prompt to warn me of what was going on down there,” said Don. “I had no idea, from up in the tree, that there was anyone else down there with you.”

“He must have been prowling around and heard us up there,” Jim said. “I didn’t hear him come up and the first thing I knew about him was when he grabbed my shoulder. It was a good thing that he thought there were only two of us.”

“When I dropped out of the tree I saw him, but it was too late to do anything about it,” explained Terry. “My first impulse was to yell to Don, but that would have been the worst thing I could have done.”
