"Yes," said Sergeant Jimmy, "he saved our lives—there's no doubt about it. But he's a spy. It breaks my heart to do it, but duty is duty! We'll have to expose him!"
He looked at Roger and Bob. Solemnly and mournfully they nodded their heads in assent.
"I don't know as much about it as you three fellows do," said Franz, "but it sounds as though you'd have to. Tough luck, but it's got to be done."
"How about you, Iggy?" asked Bob.
"I fights mit youse," said the Polish lad simply, "and what you says I say!"
"That ends it!" went on Jimmy. "I'd rather lose ten times five thousand francs than do this, but—well, let's get it over with, and then we'll jump into the fight and try to forget it."
He walked up to the group of officers, in the midst of which still stood the captain. Jimmy saluted Major Wrightson, the senior officer then present, and when the latter looked at the lad, seeing that he had something to say, Jimmy spoke:
"My comrades and I," he said, indicating his four Brothers, "wish to denounce that man as a German spy!" He spoke quietly, and pointed an accusing finger at Captain Dickerson.
"What's that?" cried the major, in great surprise.
Jimmy repeated his statement, and as he did so he kept his eyes on the face of the accused. The latter smiled faintly, but did not seem at all alarmed.
