On the first car that got away there was a horn that made Boris start convulsively as he heard its bugle note, and grasp Fred's shoulder.
"That horn belongs only to a car used by a full general!" he said.

"It must be von Hindenburg going, Fred! That flying machine brought important news!" That had been evident to Fred almost from the first.

He wondered mightily what was going to happen next.

It seemed incredible that the Germans, knowing that he and Boris must soon be found, and that only patience was necessary if they were to be caught, would so quickly give up looking for them.

And yet--Boris was right, of course.
