'It is not often I go out in the morning,' Dorothy said, 'and I should think I could prove that I did not do so on the morning of the 16th; but I cannot be sure if, in a state of somnambulism or in a sort of trance, I did not call at the jewellers and on you. I might, had I gone out, have changed that cheque in a similar state. That would have been a straightforward thing, but how could I get rid of the jewels? If I had them now and wanted to raise money on them I should not have the least idea how to do so, and I could hardly have carried out such a scheme in a state of unconsciousness. The jewellers say I was dressed in a blue dress with red spots, and I went out in a gown of that pattern on that day.' 'I did not notice the dress particularly,' Mr. Singleton said, 'but it was certainly a blue of some sort. Of course it is quite out of the question that you could have done all these things unconsciously; but what does it all mean? I am absolutely bewildered.' 'We have only one theory to account for it, Singleton. We believe, in fact we are positively convinced, that there is somewhere a girl so exactly resembling Dorothy that even those who know her well, like yourself, might take one for the other, and that she and perhaps an accomplice are taking advantage of this likeness to personate Dorothy. They have even gone the length of having a dress made exactly like hers. I will now tell you the real history of that affair that got into the papers. You will see that the party we believe to be at the bottom of it would know, or would have means of finding out, that Gilliat was our family jeweller, and that you were an intimate friend. Our theory is that revenge as well as plunder was the motive, and that the first part of the affair was simply an endeavour to injure Dorothy, and to suggest a motive for her need of money just at this time.' 'It is an extraordinary story,' Mr. Singleton said, when he heard it all. 'I cannot doubt that it is as you suggest. That my little Dorothy should behave in this way is too ridiculous to be believed for a moment; though I own that I should have been ready, if obliged, to swear in court that it was she who came to me.' 'Did she wear a veil?' Dorothy asked, suddenly. 'I forgot to ask Mr. Gilliat that.' 'Yes, she had a veil on and kept it down all the time. It was a warm day and I rather wondered afterwards at your wearing it, for I do not think I ever saw you in a veil. But I supposed that you did not want to be seen coming up to me, and that perhaps you felt that you could tell your story more easily behind it.' 'Was it a thick veil?' 'No, it seemed to me the usual sort of thing ladies wear.' 'Did you notice anything particular about the voice?'
