Exactly three weeks had passed since I bade farewell to Vera. I had breakfasted, and was standing before the window looking out upon the Izak Platz, that broad square in the centre of which the column of Alexander stands out in bold relief. Not having made up my mind whither I should repair in search of pleasure, I was idly watching the busy, ever-changing crowd of pedestrians and vehicles, when I heard the door behind me open, and, turning, confronted a tall, fair-bearded man, who had entered unannounced. He was well-dressed, and as I turned and looked inquiringly at him, he bowed and removed his hat. "Is it to M'sieur Frank Burgoyne I have the pleasure of speaking?" he asked politely, in very fair English. "Quite correct," I replied. "Allow me to present to you the _carte_ of Mademoiselle Vera Seroff, and to introduce myself. Paul Volkhovski is my name, and--er--need I tell you the object of my visit?" he inquired, showing an even set of white teeth as he smiled. "It is unnecessary," I replied, glancing at the card he took from his wallet and handed to me. "The jewels are quite safe in that box upon the ottoman. The seals, you will notice, are untouched." "_Merci_," he replied, a grin of satisfaction lighting up his countenance as he repeated, "The jewels--ah!" Crossing quickly to where the box lay, he took it up and examined it minutely. "_Ha! harosho_!" he exclaimed confidently, replacing it with care. There was something peculiar in his manner which I could not fail to notice. To tell the truth, I was rather disappointed in Vera's friend. I had imagined that any friends of hers must be men with whom I could readily associate, whereas there was nothing beyond mere bourgeois respectability in Monsieur Volkhovski. Somehow a feeling of suspicion crept over me. It was possible some one had personated the man whom I was awaiting! At that moment it occurred to me that the means at my disposal to recognise him were exceedingly slight. This man might be an impostor. "How do I know, m'sieur--if you will pardon my interrogation--that you are the person you represent yourself?" I said, regarding him keenly. With an exclamation in Russian which I did not understand, he said, "It is not for you to doubt! Mademoiselle Seroff asked you to bring the diamonds to me. Your commission is ended." "I had conceived." I replied rather warmly, "that Mademoiselle's friends were mine. Apparently I am mistaken." "It matters not--a mere trifle." "At least you will give me a receipt to show that my promise has been carried out." "She said nothing of any receipt, and I will give none." Evidently he was alarmed. "Then I shall not give up the jewels--" "Not another word! You have safely delivered them, and your commission is ended. Go back to Mademoiselle as quickly as possible. She is expecting you, and will explain all. You have rendered her a great service, and she owes you a debt of gratitude."
