CHAPTER VI.
THE ENEMY IN CAMP BERRY "Captain Prescott!" uttered Mock, starting back in dismay.
"Donner und blitzen!" (thunder and lightning) ejaculated the stoop-shouldered one.
"The fellow has just answered your question for you," Dick went on, pointing an accusing finger at the stranger.

"You know what language he was betrayed into using just now." "German, sir," said Mock.
"That's right," nodded Prescott.
"Is he one of them Kaiser-hound spies, sir ?" demanded Mock, stung to wrath and throwing grammar to the winds.

"Why, I've dreamed of catching one and tearing him to pieces.

With your permission, sir-----!" Not stopping to finish Mock threw himself upon the stoop-shouldered one, But that worthy had foreseen it, and adroitly stopped the ex-sergeant with a blow on the end of the nose that dazed him for an instant.
"I'll take care of him, Mock!" cried Captain Dick, leaping forward.
As he did so the stranger turned and fled.

No longer stoop-shouldered, but bearing himself like an athlete, the unknown turned and darted away, Prescott racing after him.
"Get back!" warned the fugitive, drawing an automatic revolver and flourishing it over his head.
Though unarmed, save for his fists, Prescott continued to pursue with all speed.
