“Listen, my boy,” I whispered in his ear. “I am Arsène Lupin. You are to deliver over to me, immediately and gracefully, my pocketbook and the lady’s jewels, and, in return therefore, I will save you from the police and enroll you amongst my friends. One word: yes or no?”

“Yes,” he murmured.

“Very good. Your escape, this morning, was well planned. I congratulate you.”

I arose. He fumbled in his pocket, drew out a large knife and tried to strike me with it.

“Imbecile!” I exclaimed.

With one hand, I parried the attack; with the other, I gave him a sharp blow on the carotid artery. He fell⁠—stunned!
