'Yes, I have been in very strange places. It would have been useless, you know, to go to Ashley Street, and ask Mrs. Beaumont to give me a short sketch of her previous history. No; assuming, as I had to assume, that her record was not of the cleanest, it would be pretty certain that at some previous time she must have moved in circles not quite so refined as her present ones. If you see mud on the top of a stream, you may be sure that it was once at the bottom. I went to the bottom. I have always been fond of diving into Queer Street for my amusement, and I found my knowledge of that locality and its inhabitants very useful. It is, perhaps, needless to say that my friends had never heard the name of Beaumont, and as I had never seen the lady, and was quite unable to describe her, I had to set to work in an indirect way. The people there know me; I have been able to do some of them a service now and again, so they made no difficulty about giving their information; they were aware I had no communication direct or indirect with Scotland Yard. I had to cast out a good many lines, though, before I got what I wanted, and when I landed the fish I did not for a moment suppose it was my fish. But I listened to what I was told out of a constitutional liking for useless information, and I found myself in possession of a very curious story, though, as I imagined, not the story I was looking for. It was to this effect. Some five or six years ago, a woman named Raymond suddenly made her appearance in the neighbourhood to which I am referring. She was described to me as being quite young, probably not more than seventeen or eighteen, very handsome, and looking as if she came from the country. I should be wrong in saying that she found her level in going to this particular quarter, or associating with these people, for from what I was told, I should think the worst den in London far too good for her. The person from whom I got my information, as you may suppose, no great Puritan, shuddered and grew sick in telling me of the nameless infamies which were laid to her charge. After living there for a year, or perhaps a little more, she disappeared as suddenly as she came, and they saw nothing of her till about the time of the Paul Street case. At first she came to her old haunts only occasionally, then more frequently, and finally took up her abode there as before, and remained for six or eight months. It's of no use my going into details as to the life that woman led; if you want particulars you can look at Meyrick's legacy. Those designs were not drawn from his imagination. She again disappeared, and the people of the place saw nothing of her till a few months ago. My informant told me that she had taken some rooms in a house which he pointed out, and these rooms she was in the habit of visiting two or three times a week and always at ten in the morning. I was led to expect that one of these visits would be paid on a certain day about a week
