Elfreda regarded her frowningly.

“I forgot that you had been in the air so long. Chad occupies the front room on this floor. We are all in the house together, but if trouble doesn’t make us wish we weren’t, I shall be much mistaken. Won Lue comes over to ask about you. He appears to have something on his mind. Have you any idea what it is?”

“Plidgins,” answered Grace laughingly. “What is it you suspect about this woman Marshall?”

“I do not suspect her any more than I do some other persons. I am beginning to believe that our supervisor isn’t as loyal to the cause as she might be. That feeling has been strengthened since Miss Marshall appeared so mysteriously.”

“Elfreda, you know how I feel toward Mrs. Smythe, but for all that I must stand up for her. With all her faults she is an American. Her presence at the front is sufficient evidence of that to satisfy me as to her loyalty. As I have said before, she is a vain and jealous woman, a fair type of the newly rich. As for the other woman, I hope to see her and form my own opinion of her. I think the Intelligence Department is considerably disturbed over spy activities. There is something else going on here too, though I haven’t yet learned what it is. I have some queer fancies in the back of my head, Elfreda, and—”

“You always did have.”

“They are not yet sufficiently clarified to make it prudent for me to speak of them, but remember what I have said. Some day I shall tell you the story that I now warn you of. Whose house is this?”

“It is occupied by a Doctor Klein, a scientific, studious-appearing fellow, and apparently very friendly to Americans. He says the Germans have been in the wrong in this war and—”

“I should be suspicious of that man, Elfreda. Either he is not a German or else he isn’t telling the truth. What is the attitude of the people of Coblenz?”

“Some appear to be afraid of the Americans, while others—these are in the majority—are sullen. The situation appears to me to be very tense, likely to result in an explosion at any moment. There are very few German men of military age here. I think our people are treating the inhabitants very leniently.”
