Monsieur Decresson touched Louis on the shoulder and motioned him to enter the automobile which was waiting. With many bows and solemn salutes the great car swung off and left me there alone. I watched it until it disappeared, and then, turning in the opposite direction, started to walk toward the Ritz. Curiously enough it never occurred to me to doubt for a moment the assurance which had been given me. I had no longer the slightest fear of arrest.

On the way I passed the Café de Paris. Then I suddenly remembered that strange little note from the girl with the turquoises. I never stopped to consider whether or not I was doing a wise thing. I opened the swing doors and passed into the restaurant. It was almost empty, except for a few people who had sat late over their luncheon. I called Léon to me.

"Léon," I said, "you remember me? I am Captain Rotherby."

He held up his hand.

"It is enough, monsieur," he declared. "If monsieur would be so good."

He drew me a little on one side.

"Mademoiselle still waits," he said in an undertone. "If monsieur will ascend."

"Upstairs?" I asked.

Léon bowed and smiled.

"Mademoiselle is in one of the smaller rooms," he said. "Will monsieur follow me?"
