Captain Jack hesitated.

"It seems a pity, too," he said. "You're rather handy with a gun. You could be of great use to me. Now, for example, I have word—picked up by my wireless station inland—that a certain ship is about to pass through these waters. It will be loaded with riches. I intend to capture it. I would like to have you lend a hand."

"You've a lot of nerve," said Frank. "You talk about capturing an American ship—or even a British or French, or of a country allied with the United States—as though it were nothing."

"Who said it was an American ship or a vessel of an allied nation?" demanded Captain Jack.

"What else could it be?" demanded Frank.

"In this case, it chances to be a German ship," said Captain Jack.

Frank looked incredulous.

"What? Didn't you know the Germans had established a naval base far to the north of this island?" asked Captain Jack. "It's there their raiders put in supplies. There are also a dozen submarines. As a matter of fact though, the Kaiser is a submarine shy. That's the one I 'cut out' about five months ago."

Frank listened to this tale with wide-open eyes.

"If you're fighting the Germans, I'm with you," he said.
