I remained in London several weeks. I stayed because the MacNairns were so good to me. I could not have told any one how I loved Mrs. MacNairn, and how different everything seemed when I was with her. I was never shy when we were together. There seemed to be no such thing as shyness in the world. I was not shy with Mr. MacNairn, either. After I had sat under the big apple-tree boughs in the walled garden a few times I realized that I had begun to belong to somebody. Those two marvelous people cared for me in that way--in a way that made me feel as if I were a real girl, not merely a queer little awkward ghost in a far-away castle which nobody wanted to visit because it was so dull and desolate and far from London. They were so clever, and knew all the interesting things in the world, but their cleverness and experience never bewildered or overwhelmed me. “You were born a wonderful little creature, and Angus Macayre has filled your mind with strange, rich furnishings and marvelous color and form,” Mrs. MacNairn actually said to me one day when we were sitting together and she was holding my hand and softly, slowly patting it. She had a way of doing that, and she had also a way of keeping me very near her whenever she could. She said once that she liked to touch me now and then to make sure that I was quite real and would not melt away. I did not know then why she said it, but I understood afterward. Sometimes we sat under the apple-tree until the long twilight deepened into shadow, which closed round us, and a nightingale that lived in the garden began to sing. We all three loved the nightingale, and felt as though it knew that we were listening to it. It is a wonderful thing to sit quite still listening to a bird singing in the dark, and to dare to feel that while it sings it knows how your soul adores it. It is like a kind of worship. We had been sitting listening for quite a long time, and the nightingale had just ceased and left the darkness an exquisite silence which fell suddenly but softly as the last note dropped, when Mrs. MacNairn began to talk for the first time of what she called The Fear. I don’t remember just how she began, and for a few minutes I did not quite understand what she meant. But as she went on, and Mr. MacNairn joined in the talk, their meaning became a clear thing to me, and I knew that they were only talking quite simply of something they had often talked of before. They were not as afraid of The Fear as most people are, because they had thought of and reasoned about it so much, and always calmly and with clear and open minds. By The Fear they meant that mysterious horror most people feel at the thought of passing out of the world they know into the one they don’t know at all.
