“There has been no traitor in the camp, Major,” the other hastened to assure him. “But nevertheless we have learned that all the while you were there talking to us, and while we have been discussing the intended raid in low tones among ourselves, there was a spy concealed in the hangar who must have heard more or less of what was said, despite our precautions.”
The soldier jumped to his feet. He looked almost frightened as he stared into the face of Frank Chester.
“You are sure of what you say, are you, Frank?” he asked with an effort.
“Oh! there isn’t the slightest doubt about it,” came the reply.
Then Major Nixon began to breathe easier. He saw that Frank was smiling, and his common sense told him the boy would not be likely to show such freedom from anxiety if things were as bad as he had at first feared.
“Frank, tell me the rest without delay. I know you’ve got good news back of this astonishing disclosure. Where is that spy now?”
“In the hangar still,” replied Frank.
“Did you take him prisoner?” demanded the Major eagerly.
“Yes, and I’ll tell you how it was done, sir. We had quite a little circus for a short time, believe me.”
Major Nixon listened, and as he heard how Pudge sat down upon the surprised eavesdropper whom they had dragged from the locker, he even smiled, for that terrible fear had by now left his soul.
