under arrest."

Neither Hal nor Chester paid much attention to what the Greek officer was
saying. They were too busily engaged watching the antics of their
erstwhile prisoner, who, now safe on his own side of the line, was
shaking his fist in their direction and making other fierce gestures.

Now Hal turned to the Greek officer.

"Will you accompany us back close to the line," he said, "that we may
hear what yonder little fellow is talking about? He seems to be greatly
put out about something."

"First tell me what you are doing here?" was the command.

Hal explained as rapidly as possible and then repeated his request that
they be allowed to go back toward the border a few moments.

At last the officer gave his permission.

Chester, Hal, Colonel Anderson, Ivan and Nikol, each grinning, moved back
toward the border. Stubbs hung back, and seeing this, Hal called:

"Come along, Mr. Stubbs. Here is one time you may look at an enemy with
impunity."

Stubbs followed.

The Bulgarian officer was still angrily waving hit arms about when they
neared him.
