“Ah, in Beroldstein.” The name seemed to awaken thoughts which were hardly pleasant, but she dismissed them with a little inward careless laugh. “Well, good-night, Herr Lieutenant, and many thanks. I hope there is no need to ask you not to speak of this affair.”

Her manner was a curious mixture of coldness and a sense of duty which told her that she owed her defender some graciousness.

“There is no need, Princess,” he answered gravely. “You may trust my honour.”
