A horn tooted softly just behind us and we turned. A big limousine was waiting to get in front of the door. The man driving it was Niko, Ivanovitch’s servant. Pride jumped into the driving seat of our car and pulled away at once, saluting without another word. I turned and went up to the door. Ivanovitch himself let me in. “Ah, you’re back again in time. I’m glad; for I should have had to go without you. However, I’ve telephoned about you, and they are expecting you. Now let us go, shall we?” “Expecting me, are they?” I thought. “That makes it nice.” Ivanovitch picked up his coat and hat from a chair and held the front door open for me, and together we went down to the car. Niko had disappeared, but, to my surprise, another man sat in the driving seat. Naturally I looked him over pretty sharply. And then I started in my turn, For the face of Ivanovitch’s new driver was quite familiar to me. He was one of the two men who had been with Vining the day he caught me burgling his flat! A wave of feeling went through me as I stepped into the car. It was compounded of hope and delight. I hoped the man would not recognize me because of the mask I wore that night. But I was tremendously elated. For here was final proof positive that I was on the right track. Vining and Ivanovitch, Mrs. Fawcette and the rest of the bunch of Russians were all in the same gang then. And the orgies of Vining’s stories to Moore must be the orgies of Ivanovitch’s stories to me. At last I was on my way to the headquarters of the gang. Ivanovitch stepped in after me and closed the door. As he sat down beside me he laughed softly. “I thought afterwards that it would be so dull for us both if I drove,” he observed. “So I sent for the chauffeur after all. You see, some one would have to ride with you anyway, to be sure you did not look out to find how and whither we were going.” “What a mystery!” I laughed. “It’s like the _Arabian Nights_.” “Ye-es,” he drawled; “quite like, indeed.” The car started smoothly away from the curb, and Ivanovitch leaned forward and pressed a button half concealed by the rug rack. To my amazement, shutters tolled silently up over all the windows and we were in total darkness. A moment later an electric globe flashed on overhead and I turned to find the amused eyes of my guide on me. “Neat, isn’t it?” he inquired. “But it is all marvelous,” I answered in a delighted tone. “Judging by the efficiency of your preparations, these must be a wonderful lot of evenings. How long a drive is it, if you can tell me so much?” He shook his head, smiling still. “Not even that, my friend. I am sure you would not give us away; but you see we make a rule to trust no one, and we stick to it. It’s a pretty good plan, don’t you think so?” “Yes, indeed,” I answered. “But then you must be one of the organizers or officers or charter members, or whatever you call it?”
