"Yes, I am off," he replied, with a kind of forced gaiety; "I am bad company for anyone to-night, and I won't inflict myself upon you, Casimir. Au revoir! I will put mademoiselle into the carriage if she will permit me."

We went down the steps together, Heliobas watching us from the open door. As the Prince assisted me into the brougham, he whispered:

"Are you one of them!"

I looked at him in bewilderment.

"One of them!" I repeated. "What do you mean?"

"Never mind," he muttered impatiently, as he made a pretence of covering me with the fur rugs inside the carriage: "if you are not now, you will be, or Zara would not have kissed you. If you ever have the chance ask her to think of me at my best. Good-night."

I was touched and a little sorry for him. I held out my hand in silence. He pressed it hard, and calling to the coachman, "36, Avenue du Midi," stood on the pavement bareheaded, looking singularly pale and grave in the starlight, as the carriage rolled swiftly away, and the door of the Hotel Mars closed.
