Seeing the “Sister” hurrying towards me, I got down, wondering if she meant to speak.

“Pardon, m’sieur,” she exclaimed in musical French, rendered almost breathless by her quick walk, “but is this the automobile of M’sieur Bellingham, of London?”

I raised my eyes, and saw before me a face more pure and perfect in its beauty than any I had ever seen before. Contrary to what I had believed, she was quite young—certainly not more than nineteen—with a pair of bright dark eyes which had quite a soupçon of mischief in them. For a moment I stood speechless before her.

And she was a nun! Surely in the seclusion of the religious houses all over the Continent the most beautiful of women live and languish and die. Had she escaped from one of the convents in the neighbourhood? Had she grown tired of prayers, penances, and the shrill tongue of some wizen-faced Mother Superior?

Her dancing eyes belied her religious habit, and as she looked at me in eager inquiry, and yet with modest demeanour, I felt that I had already fallen into a veritable vortex of mystery.

“Yes,” I replied, also in French, for fortunately I could chatter that most useful of all languages, “this car belongs to M’sieur Bellingham, and if I am not mistaken, Mademoiselle is named Pierrette?”

“Yes, m’sieur,” she replied quickly. “Oh, I have been waiting half an hour for you, and I’ve been so afraid of being seen. I—I thought—you were never coming—and I wondered whatever I was to do.”

“I was delayed, mademoiselle. I have come straight from London.”

“Yes,” she said, smiling, “you look as though you have come a long way;” and she noticed that the car was very dusty, with splashes of dried mud here and there.

“You are coming to Monte Carlo with me,” I said, “but you cannot travel in that dress—can you? Mr. Bellingham has sent you something,” I added, taking out the cardboard box.
