McKenzie's lips were set in a determined line. It was plain that he would need no urging.
"Well," said one of the Germans, "it's my belief you are also spies."
"Hands up!" repeated Hal.
"If you must have it you must!" exclaimed the first German.
His hand flashed up and in it was a revolver.
McKenzie's revolver flashed. The German dropped back.
The man at the wheel released his hold on the steering apparatus and also reached for a gun. Hal dropped him without changing his position.
One of the Germans, before either Hal or McKenzie could stop him, hurled himself over the far side of the car. The other two raised their hands.
"That other fellow is probably bent on mischief," said Hal to himself, "but we'll have to take a chance. Cover 'em" he ordered McKenzie, "while I get their guns!"
Hal advanced to the side of the car and deprived the two Germans of their revolvers. Then he climbed in and motioned the Germans to get out. After that he bent over the still form in the bottom of the car. It was Chester.
