"Oh, oh!" Valentine remarked. "Still I hope I shall alter your opinion."

"Try it. Stay!" he added, suddenly changing his tone. "Enough of that sort of farce. I am in your power—nothing can save me. Kill me—no matter, I shall not say a word."

The two men exchanged glances of strange expressiveness.

"You are an idiot," Valentine answered coldly; "you understand nothing."

"I understand that you want to know the secrets of the expedition."

"You are a fool, my dear friend. Did I not tell you that I knew all?"

The bandit seemed to reflect for a minute.

"What do you want, then?" he said.

"Merely to buy you."

"Hum! that will be dear."
