"You're not pro-German, then, like so many of your countrymen?" Dave asked, with a smile.

"There are few of us who are pro-German in Denmark," replied the ship's surgeon. "Though, until your Entente allies can protect us against powerful Germany's wrath it is not prudent for us to be too outspoken in favor of England, France and America."

"From your accent you've been in our country?" Dave hinted.

"I took my degree in an American medical school, but I am a Dane. And now, sir, your name?"

"David Darrin, lieutenant-commander, United States Navy."

"And I am Dr. Valpak. And now, Mr. Darrin, I advise that you rest your mind, eat what I am going to order sent here, and then take another nap."

Dave gladly ate of the sea biscuit and soup that were brought to him, after which Dr. Valpak felt his pulse, administered a drink of something with an unfamiliar taste, then uttered the professional command:

"Sleep!"

Dr. Valpak closed the door from outside. Dave closed his eyes, and enjoyed the luxury of another nap.
