The shock was so overwhelming, that in a moment my whole physical organisation seemed at a standstill. I lost my balance. The whole place swam before me. I felt myself swaying to and fro. If I had not leaned against the glass case, I believe I should have fallen. In my whole life I had never before behaved so stupidly. A voice recalled me to myself. 'Take care there, sir! Do you want to break the glass?--or to knock the whole thing over?' A person who seemed to have charge of the place addressed to me this, under the circumstances, not unnatural inquiry. I steadied myself as best I could. After a second or two I began to see things with something approaching to clearness. By degrees I got the man inside the case, as it were, in focus. Was it Twickenham? I could not decide. It was fifteen years since I had seen him. As regards certain details my memory had possibly become a trifle blurred. Yet it was absurd to suppose that I could by any possibility fail to recognise him if we met. If it was not he, then it was his double. His very self, reproduced in another form. Fifteen years make a difference in a man's appearance--especially fifteen such years as it might be taken for granted that Twickenham had lived. Allowing, in my mind's eye, for that difference, I became more and more at a loss to determine whether this was or was not the absentee. Never before had I been conscious of such a condition of mental bewilderment. I lost my presence of mind; was unable to arrange my thoughts; became incapable of deciding what to say or do. The situation was the very last I had expected. Coming at such a moment it found me wholly unprepared. If this was Twickenham, this uncanny-looking mountebank in the guise of death, then the entire edifice we had been laboriously constructing for fifteen years crumbled at a touch. Edith's words, 'You and I can never marry,' would be indeed proved true. And Reggie and Vi--what of them? Where would Reggie be if his brother turned up at this hour of the day? And I? Reggie was my debtor to the extent of nearly every penny I had ever had. If he was not the Marquis, because Leonard still was in the flesh, then he and Vi, and I, were ruined. And Edith could never marry a pauper. Down toppled our whole card edifice, never again to be rebuilt by us.
