"Do you know," he asked, "where she is?"

"Yes."

It was amazing what effect the monosyllable had upon him. The mask which he carried always with him fell suddenly away. He turned upon her with an abruptness almost disconcerting. His eyes were lit with fire, and there was a strange flush upon his cheeks.

"Where," he demanded—"where is she?" The Duchess looked at him with sympathy. She was a kindly woman, and she had probed his secret long ago.

"She is in a little village some five hundred miles across the frontier, in Siberia. I had imagined that you might have known."

"Siberia!" He repeated the word in blank amazement. The Duchess nodded.

"Now I have told you something very interesting," she said, "and in return I am going to ask you something. You quarrelled with her, did you not?"

"Scarcely that. I asked her to marry me," he answered.

"Which of course was impossible."

"Impossible? Why?"
