"Sounds like our car," said Bob. "All those motors make the same sort of noise."
"Pretty good ears you have," remarked Hugh.
"You ought to see old Heinie," said Bob. "He may look stupid, but he can tell almost any make of car just by the noise it makes."
"What'll he say when you get home?" queried Hugh.
"He'll be mad. He doesn't think I know how to drive the car, and if there is any dirt on it he'll be madder yet."
"The roads aren't muddy now though."
"I know it, but he'll be cross if there's dust on it even."
They emerged on the main road, looked carefully in both directions, and then still keeping to the side of the road, started back toward the spot where they had left the car. A ghostly moon, in its last quarter, shed its pale light on the highway, and aided the boys to distinguish their surroundings.
"There's the place," said Bob a moment later.
They ran quickly across the road and hurried towards the clump of trees where they had hidden the car. Both boys would feel relieved when they were seated in their conveyance once more, and on their way home. It was nervous work prowling around the countryside at night with a suspicious gang of men lurking near.
