"And my wife, Antonio--where is she?" I inquired, looking him straight in the face. "Ah, how can I tell, Signor Holford? Have I not already told you that I am entirely ignorant of her whereabouts?" And he exhibited his bony palms. "You have been with your master in Hungary or in Roumania, I hear?" "Certainly! Why not?" he said, as we stood within the wide hall. "But the Signor Kirk is upstairs in the study. Perhaps you will care to see him? I believe he has been trying to telephone to you at Chiswick." I started in eager anticipation. "Of course, I'll see Mr. Kirk," I said. And endeavouring to steady my nerves and control my temper, I mounted the thickly-carpeted stairs to the room I so well remembered. The point which puzzled me was whether I should now boldly accuse Kirk of duplicity and fraud. If I did, I feared that, to the bogus Professor, he might give the alarm, and that he would again slip through my fingers. On my way to the study I resolved upon a purely diplomatic course. I would not let Kirk know of my visits to Birmingham and Sheffield, or even that I had noticed the report of the Professor's announcement. For a second I held my breath. Then I turned the handle of the door and boldly entered. "Why, my dear Holford," cried Kirk, jumping up from the writing-chair and grasping my hand as though delighted at my visit, "I've been trying to get on to you at your garage three times this morning, but your people have been engaged. You must be pretty busy down there--eh?" The thin-faced man was, indeed, a perfect actor. "I called to see Antonio," I said. "I heard he had returned." "Then it is fortunate--most fortunate," he said. "I am awaiting the return of someone who is very desirous indeed of making your acquaintance. It was for that reason that I've been trying to ring you up." My lips parted in an incredulous smile. So the impostor was anxious to meet me--doubly anxious, no doubt, because he was aware that I knew the truth of poor Greer's death. Yes, I would meet and unmask him. CHAPTER TWENTY EIGHT. "NO TRUMPS." In the failing London light, as Kirk rose and stood near the window, his countenance was even more sinister and more mysterious than ever. About his lips played that enigmatical, sarcastic smile which so tantalised and irritated me. Here was a man who had actually deceived the hard-headed Sheffield magnate into a belief that he possessed power and influence, while, in reality, he was only a clever adventurer. "Sit down, Holford," he said, in a cheery voice, inviting me to a big leather arm-chair. "The time has come when it is very necessary for you and me to arrive at some clear and definite understanding." "Yes," I cried, "I agree with you. Have I not asked you all along for a clear statement of facts? Have I not urged you to tell me where I can find my wife?"
