He went out.

“Wait here a moment,” urged Madame Trebassof, who did not know how to take this abrupt action and whose anxiety was really painful to see.

She disappeared after the man of the false astrakhan. A few moments afterwards she returned. She appeared even more agitated.

“I beg your pardon,” she murmured, “but I cannot let them go like this. They are much chagrined. They have insisted on knowing where they have failed in their service. I have appeased them with money.”

“Yes, and tell me the whole truth, madame. You have directed them not to go far away, but to remain near the villa so as to watch it as closely as possible.”

She reddened.

“It is true. But they have gone, nevertheless. They had to obey you. What can that paper be you have shown them?”

Rouletabille drew out again the billet covered with seals and signs and cabalistics that he did not understand. Madame Trebassof translated it aloud: “Order to all officials in surveillance of the Villa Trebassof to obey the bearer absolutely. Signed: Koupriane.”

“Is it possible!” murmured Matrena Petrovna. “But Koupriane would never have given you this paper if he had imagined that you would use it to dismiss his agents.”
