"'I was fully prepared to hear the bad news,' he explained, 'which my man Robertson told me when I arrived. The letter I got last night was a bogus one; there is no such person as J. Collins, M.D. My brother had never felt better in his life. You will, I am sure, very soon trace the cunning writer of that epistle—ah! but I was in a rage, I can tell you, when I got to the Metropole at Brighton, and found that Emile, my brother, had never heard of any Doctor Collins.
"'The last train to town had gone, although I raced back to the station as hard as I could. Poor old Robertson, he has a terrible cold. Ah yes! my loss! it is for me a very serious one; if I had not made that lucky bargain with Mr. Shipman last night I should, perhaps, at this moment be a ruined man.
"'The stones I had yesterday were, firstly, some magnificent Brazilians; these I sold to Mr. Shipman mostly. Then I had some very good Cape diamonds—all gone; and some quite special Parisians, of wonderful work and finish, entrusted to me for sale by a great French house. I tell you, sir, my loss will be nearly £10,000 altogether. I sell on commission, and, of course, have to make good the loss.'
"He was evidently trying to bear up manfully, and as a business man should, under his sad fate. He refused in any way to attach the slightest blame to his old and faithful servant Robertson, who had caught, perhaps, his death of cold in his zeal for his absent master. As for any hint of suspicion falling even remotely upon the man, the very idea appeared to Mr. Knopf absolutely preposterous.
"With regard to the old charwoman, Mr. Knopf certainly knew nothing about her, beyond the fact that she had been recommended to him by one of the tradespeople in the neighbourhood, and seemed perfectly honest, respectable, and sober.
"About the tramp Mr. Knopf knew still less, nor could he imagine how he, or in fact anybody else, could possibly know that he happened to have diamonds in his house that night.
"This certainly seemed the great hitch in the case.
"Mr. Ferdinand Knopf, at the instance of the police, later on went to the station and had a look at the suspected tramp. He declared that he had never set eyes on him before.
"Mr. Shipman, on his way home from business in the afternoon, had done likewise, and made a similar statement.
"Brought before the magistrate, the tramp gave but a poor account of himself. He gave a name and address, which latter, of course, proved to be false. After that he absolutely refused to speak. He seemed not to care whether he was kept in custody or not. Very soon even the police realized that, for the present, at any rate, nothing could be got out of the suspected tramp.
