Phil and Dick, after an hour or more spent in this way, were flying back toward Castleton and were still some miles distant from the town. They were only a few hundred feet above the ground and could see everything beneath them with great distinctness.

Suddenly Dick touched Phil’s arm.

“Something going on down there,” he said.

Phil looked in the direction indicated, and saw what seemed to be an angry conversation going on between a girl and man. Even as he looked, the girl started to run. The man ran after her and caught her by the arm and seemed to be trying to drag her toward an automobile drawn up at the side of the road.

“Here’s where we get busy,” exclaimed Phil.

He grasped a lever and the machine with a great sweep came down in a field only a short distance from the couple.

In a moment the Radio Boys were out of the fuselage and hurrying toward the scene of commotion.

As they neared the two, the girl gave a glad cry, wrenched her wrist from the man who now seemed willing enough to release her and came running toward them.

“Oh, I am so glad you came,” she cried, the tears streaming down her face.

“What’s the trouble?” asked Phil.
