"Rather clever of von Kufner," I commented; "how do you suppose he got trail of it?"
"He admitted his trailing quite frankly," said Marguerite, "for as soon as we were out of the shop, I accused him of preparing the scene. 'Of course,' he said, 'but I had to convince you that your chemist was not so saintly as you thought him. His banker is a friend of mine, and I asked him about von Armstadt's account. He is keeping a girl on the Free Level and evidently also making love to one of better caste, or he would hardly be buying ruby necklaces.' I told von Kufner that he was a miserable spy, but he only laughed at me and said that all men were alike and that I ought to find it out while I was young--and then he asked if I would like him to have the young woman's record sent up from the Free Level for my inspection. I ordered him to leave me at once and I have not seen or heard from him since, until I received a note from him today telling me of the Royal order for you to go to the Arctic."
I first set Marguerite's mind at ease about the checks to Bertha by explaining the incident of the geography, and then told the story of Katrina and the meeting in the café, and the later affair of Holknecht and the necklace.
"And you will promise me never to see her again?"
"But you have forgotten," I said, "that I am leaving Berlin in four days."
"Oh, Karl," she cried, "I have forgotten everything--I cannot even remember that new name you gave us--I believe I must be dreaming--or that it is all a wild story you have told us to see how much we in our simplicity and ignorance will believe."
"No," I said gently, "it is not a dream, though I could wish that it were, for Grauble says that there is no hope of taking you with me; and yet I must go, for the Emperor has ordered me to the Arctic and von Kufner will see to it that I make no excuses. If I once leave Berlin by submarine with Grauble I do not see how I can refuse to carry out my part of this project to which I am pledged, and make the effort to reach the free world outside."
Marguerite turned on me with a bitter laugh. "The free world," she cried, "your world. You are going back to it and leave me here. You are going back to your own people--you will not save Germany at all--you will never come back for me!"
"You are very wrong," I said gently. "It is because I have known you and known such men as Dr. Zimmern and Col. Hellar that I do want to carry the message that will for ever end this sunless life of your imprisoned race."
"But," cried Marguerite, "you do not want to take me; you could find a way if you would--you made the Emperor do your bidding once--you could do it again if you wanted to."
