"But," I said, "I ask it as a favor."

"Do you?" She gave me a divine smile, and yielded.

At her request we did not leave the church together. She preceded me. I waited a few minutes, and then walked slowly out. Happening to look back as I passed along the square, I saw a woman's figure which was familiar to me, and, dominated by a sudden impulse, I returned quickly on my steps. The woman was Yvette, and she was obviously a little startled when I approached her.

"Are you waiting for your mistress?" I said sharply. "Because...."

She flashed me a look.

"Did monsieur by any chance imagine that I was waiting for himself?"

There was a calm insolence about the girl which induced me to retire from that parley.

In two hours I was on my way to London.
