Rouletabille looked him over. The Prefect of Police had an arm in a sling, but he was bright and shining as a new ten-rouble piece, while he, poor Rouletabille, was so abominably soiled and depressed. Where did he come from? Koupriane understood his look and smiled.

“Well, I have just come from the Finland train; it is the best way.”

“But what can you have come here to do, Excellency?”

“The same thing as you.”

“Bah!” exclaimed Rouletabille, “do you mean to say that you have come here to save Natacha?”

“How—to save her! I come to capture her.”

“To capture her?”

“Monsieur Rouletabille, I have a very fine little dungeon in Saints Peter and Paul fortress that is all ready for her.”

“You are going to throw Natacha into a dungeon!”

“The Emperor’s order, Monsieur Rouletabille. And if you see me here in person it is simply because His Majesty requires that the thing be done as respectfully and discreetly as possible.”
