But that wasn’t the only queer thing in the house. The very next day I found out that Mrs. Brympton had no nurse; and then I asked Agnes about the woman I had seen in the passage the afternoon before. Agnes said she had seen no one, and I saw that she thought I was dreaming. To be sure, it was dusk when we went down the passage, and she had excused herself for not bringing a light; but I had seen the woman plain enough to know her again if we should meet. I decided that she must have been a friend of the cook’s, or of one of the other women servants: perhaps she had come down from town for a night’s visit, and the servants wanted it kept secret. Some ladies are very stiff about having their servants’ friends in the house overnight. At any rate, I made up my mind to ask no more questions.
