I asked her if I might call and see her. She hesitated for a moment, glanced round to see if any one was near us, and then said, "Yes; to-morrow at a quarter to five." I begged Madame de Rastail to tell me about her; but all that I could learn was that she was a widow with a beautiful house in Park Lane, and as some scientific bore began a dissertation on widows, as exemplifying the survival of the matrimonially fittest, I left and went home.
'The next day I arrived at Park Lane punctual to the moment, but was told by the butler that Lady Alroy had just gone out. I went down to the club quite unhappy and very much puzzled, and after long consideration wrote her a letter, asking if I might be allowed to try my chance some other afternoon. I had no answer for several days, but at last I got a little note saying she would be at home on Sunday at four and with this extraordinary postscript: "Please do not write to me here again; I will explain when I see you." On Sunday she received me, and was perfectly charming; but when I was going away she begged of me, if I ever had occasion to write to her again, to address my letter to "Mrs. Knox, care of Whittaker's Library, Green Street." "There are reasons," she said, "why I cannot receive letters in my own house."
