"You have met the person who calls himself Captain Wilson. I say 'calls himself' because I have reason now to believe that it is not his correct name. It would take me too long if I were to describe all the means by which he obtained an introduction to me and ingratiated himself into my friendship and the affection of my daughter. He brought letters from foreign colleagues which compelled me to show him some attention. And then, by his own attainments, which are considerable, he succeeded in making himself a very welcome visitor at my rooms. When I learned that my daughter's affections had been gained by him, I may have thought it premature, but I certainly was not surprised, for he had a charm of manner and of conversation which would have made him conspicuous in any society. "He was much interested in Oriental antiquities, and his knowledge of the subject justified his interest. Often when he spent the evening with us he would ask permission to go down into the museum and have an opportunity of privately inspecting the various specimens. You can imagine that I, as an enthusiast, was in sympathy with such a request, and that I felt no surprise at the constancy of his visits. After his actual engagement to Elise, there was hardly an evening which he did not pass with us, and an hour or two were generally devoted to the museum. He had the free run of the place, and when I have been away for the evening I had no objection to his doing whatever he wished here. This state of things was only terminated by the fact of my resignation of my official duties and my retirement to Norwood, where I hoped to have the leisure to write a considerable work which I had planned. "It was immediately after this--within a week or so--that I first realized the true nature and character of the man whom I had so imprudently introduced into my family. The discovery came to me through letters from my friends abroad, which showed me that his introductions to me had been forgeries. Aghast at the revelation, I asked myself what motive this man could originally have had in practising this elaborate deception upon me. I was too poor a man for any fortune-hunter to have marked me down. Why, then, had he come? I remembered that some of the most precious gems in Europe had been under my charge, and I remembered also the ingenious excuses by which this man had made himself familiar with the cases in which they were kept. He was a rascal who was planning some gigantic robbery. How could I, without striking my own daughter, who was infatuated about him, prevent him from carrying out any plan which he might have formed? My device was a clumsy one, and yet I could think of nothing more effective. If I had written a letter under my own name, you would naturally have turned to me for details which I did not wish to give. I resorted to an anonymous letter, begging you to be upon your guard.
