“Perhaps,” the Ambassador said thoughtfully, “he never knew.”

“One cannot tell,” Penelope answered.

“Did he say anything when you discovered them?” the Ambassador asked.

“Nothing,” Penelope declared. “It was not necessary. I saw his face. He knows that I understand. It may have been some one else connected with the house, of course, but the main fact is beyond all doubt. Those murders were instigated, if they were not committed, by the Prince.”

The Ambassador walked to the window and back again.

“Penelope,” he said, “you have only confirmed what I felt must be so, but even then the certainty of it is rather a shock.”

She gave him her hand.

“I have told you the truth,” she said. “Make what use of it you will. There is one other thing, perhaps, which I ought to tell you. The Prince is going back to his own country very shortly.”

Mr. Harvey nodded.

“I have just been given to understand as much,” he said. “At present he is to be met with every day. I believe that he is even now in my drawing rooms.”
