No group of German plotters had thus far shown themselves to be so utterly unregardful of their own safety.

Ruth believed Irma Lentz to be quite bitter against the United States and its war aims; but she could not imagine the self-styled “artist” to be on the point of risking her personal safety on behalf of America’s enemies.

These same beliefs influenced Mr. Dowd’s mind; and he said frankly:

“It may be well for us to take up the matter with Captain Hastings. However, I cannot really believe that German spies would try to sink the ship, and so endanger their own safety.”

“It does not seem reasonable,” Ruth admitted. “Nor do I mean to say I believe anything like that is on foot. I do think, however, that the woman and that seaman, or stoker, or whatever and whoever he is, should be watched. They may purpose to do some damage to the Admiral Pekhard after she docks at New York.”

“True. And you say there is a third person—a man named Boldig? His name is not on the passenger list.”

“That is so,” admitted Ruth, who had read the purser’s list.

“I’ll scrutinize the crew list as well,” said Mr. Dowd, thoughtfully. “Of course, he may not use that name. I remember nothing like it. Well, we shall see. Thank you, Miss Fielding. I know Captain Hastings will wish to thank you in person, as well.”

Ruth did not expect to be immediately called to the captain’s chartroom or office. Nor was her mind entirely filled with thoughts regarding German spies.

She had, indeed, one topic of thought that harrowed her mind continually. It was that which kept her awake on this first night at sea, as much as did the dull ache in her injured shoulder.
