said:

"Well, we've kept you longer than we should. If this gentleman will give
my government good money for its revenue we'll bid you _bon voyage_. I
suppose there's no objection to my keeping those?" He pointed to the
spurious bills.

"I have paid dearly for them," the professor remonstrated.

"I'm sorry, but you won't lose any more than you've already lost--nor
gain more, as you won't think of using them!"

"Why should I not use them? I will use them--_certainement!_"

"Be explicit, or forever hold your peace," Tommy laughed. "Can't you see
the man reaching for his handcuffs?"

But Monsieur, thoroughly aroused, waved the crisp bills with a great
show of indignation, crying:

"If there is a way to run this cheat to earth I, alone, will know it!
Then you will want me to be telling you! For my own pleasure I have made
a study of counterfeiters and their methods. Perhaps it may surprise you
to learn that the police of Europe come to Bucharest and consult with

We laughed, although I felt tremendously proud of the professor, having

"Then help yourself so I, also, may be helped. But let me take one for
my government and, when you finish with the other, mail it to me with
your report. I shall appreciate your assistance, really."

Monsieur was delighted.

They left us then, and again we settled about the cockpit; each waiting

and my ears strained with listening toward the black Gulf--listening for
a voice, or the unnamable noise of the gods knew what, that might float
to me across the water. I think Tommy half expected me to suggest that
we take one of the small boats, and went to his room to put on darker
clothes. In a few minutes Monsieur yawned and followed him--though I
rather suspected that his yawn was caused more by nervousness than the
want of sleep. A moment later Gates, standing near the wheel, softly
called my name, so I arose and went to him.

It must be remembered that Gates was absolutely dependable. There were
no frills about the old skipper, he shared not one superstitious
sentiment in common with Tommy, and it is extremely doubtful if he knew
the sensation of fear; therefore, when I saw his face, I was astonished,
and in alarm asked:
