"You go with him every night to the restaurant in the Place d'Anjou?" I asked.

"I go there very often," she answered. "Monsieur, unless I am mistaken, is a stranger there."

I nodded.

"Last night," I told her, "I was there for the first time."

"You came," she said, toying with her empty liqueur-glass, "with Louis."

"That is so," I admitted.

"Louis brings no one there without a purpose," she remarked.

"You know Louis, then?" I asked.

She raised her eyebrows.

"All the world knows Louis," she continued. "A smoother-tongued rascal never breathed."
