She gave me her hand, and smiled her most bewitching smile. I turned and stared at Louis. He had no alternative but to fall back a pace or two.

"Madame," I said, bending towards her, "it was here that Bartot came and dined. I have heard it whispered that it is not safe to eat here if you are not a friend of Louis'!"

For a moment she failed to grasp the significance of my words. Then the color died slowly out of her cheeks. Her face was like the face of an old woman. Fear had come suddenly, and she was haggard.

"You mean that he would dare, monsieur?" she said—

"It is easy," I answered. "A dozen or more of these waiters are his creatures. From what I have heard I gather that your visit here with this gentleman is for a purpose inimical to some scheme in which Delora and Louis are interested. I warn you that if it is so, you had better change your mind about lunching."

"We will go at once!" she answered. "You are very kind. I came to confront Louis and that other with me," she declared, nodding vigorously at her companion. "I came because I would have them understand who it was that had ruined their plans, because they made use of me—of Bartot and me—and threw us aside like gloves that were finished with. But it was a foolish thing to do, monsieur. I see that, and I thank you now for your warning."

She gathered her things together for her departure, and leaned across towards her companion. What she said to him I do not know, for I returned to my place.

"They will not eat," I whispered to Lamartine. "Tell me, who is the man?"

"Hush!" Lamartine said. "Look there!"

Apparently angry words had been passing between Felicia and Delora. She had risen to her feet, notwithstanding his efforts to detain her, swept past my table with scarcely a glance, and made her way towards where the two latest arrivals were sitting. She stooped down towards the man, and talked to him earnestly for several moments. All the time he looked at her with the puzzled, half-vacant expression of a child who is confronted with something which it does not understand. Delora had risen to his feet, and stood nervously clutching the serviette in his hand. Louis hurried up to him, and they talked together for a moment.
