“You are the devil, Prince Kalkov,” I cried furiously. “This is just another of your infernal schemes.”

“Is that quite just to me, when I have offered you a safe conduct across the frontier, or to anywhere you please? It is you who place me in this awkward situation.”

“To hell with your hypocrisy,” I exclaimed, losing my head in my rage. “Speak out bluntly, and say what you do mean—that if I won’t consent to leave the country you will take this devil’s way of getting me into one of your cursed prisons while you carry out your other plans.”
