"Very good," he growled. "You can go. I shall see your friends,
instead."

"When you get through with 'em you'll think they're idiots," grinned
Captain Jack Benson.

Herr Radberg wasn't a fool. Neither was he a rascal, expert in offering
bribes. Brought up within the wall's of a German university, he would
have been willing to lay down his life instantly for the good of the
Fatherland. Yet he couldn't understand that men of other nations could
be just as devoted to their own countries. From Herr Professor
Radberg's point of view Germany was the only country in the world that
was fitted to inspire a real and deep sense of patriotism.

"No harm done, Professor," said Jack, moving toward the door, and
turning the key to unlock it. "I'm sorry you had all the trouble and
expense of coming to Dunhaven on a useless errand. Good-bye!"

"Ach! You may go, but you will come back," scowled the other. "If
not, your comrades will, I hope, prove to be young men of better sense
and judgment."

"Oh, they'll listen to you," smiled Jack. "Good-bye!"

"I shall have two of you, anyway," were Radberg's last words before the
door of the outer room closed and Jack's footsteps sounded in the
corridor.
