"Help, Mr. Totten, help!" called the seaman in a low voice that none the less reached the ears of the departing lieutenant.

Then Runkle moved directly up to the spy leering into his face and making insulting signs that caused the fellow to flush red.

"You're no good—savvy?" insisted Runkle in a low tone, making more faces and gestures.

"He's going to try to rob me, sir!" cried Runkle, not very effectively dodging the blows that the fellow aimed at him.

"Here, what are you up to?" demanded Totten, also in English, as he reached out to grab the spy's collar.
