"Louis," I said, "is this a great joke, or are you talking to me in sober, serious earnest?"

"I am talking in earnest, monsieur," Louis said slowly. "I have not exaggerated or spoken a word to you which is not the truth."

"Let me understand this thing a little more clearly," I said. "What has Ferdinand Delora done that he need fear a murderous assault? What has he done to make enemies? Is he a criminal, or are those who seek him criminals?"

"He carries with him," Louis said slowly, "a secret which will produce a great fortune. There are others who think that they have a right to share in it. It is those others who are his enemies. It is those others who hope to attain by force what they could gain by no other means."

A sudden inspiration prompted my next question.

"Was Tapilow one of those?" I demanded.

Louis nodded gravely.

"Monsieur Tapilow was one of those who claimed a share, but he was not willing to run the smallest risk," he assented.

"And for that reason," I remarked, "he is well out of the way! I understand. There is one more question, Louis, and it is one which you must answer me truthfully. You can imagine what it is when I tell you that it concerns mademoiselle!"

"Mademoiselle is innocent of the knowledge of any of these things," Louis declared earnestly. "She is a very charming and a very beautiful young lady, but if ever a young lady needed friends, she does!"
