I hurried along the road at the top of my speed without seeing anything of Sir Henry, until I came to the point where the moor path branches off. There, fearing that perhaps I had come in the wrong direction after all, I mounted a hill from which I could command a view—the same hill which is cut into the dark quarry. Thence I saw him at once. He was on the moor path about a quarter of a mile off, and a lady was by his side who could only be Miss Stapleton. It was clear that there was already an understanding between them and that they had met by appointment. They were walking slowly along in deep conversation, and I saw her making quick little movements of her hands as if she were very earnest in what she was saying, while he listened intently, and once or twice shook his head in strong dissent. I stood among the rocks watching them, very much puzzled as to what I should do next. To follow them and break into their intimate conversation seemed to be an outrage, and yet my clear duty was never for an instant to let him out of my sight. To act the spy upon a friend was a hateful task. Still, I could see no better course than to observe him from the hill, and to clear my conscience by confessing to him afterwards what I had done. It is true that if any sudden danger had threatened him I was too far away to be of use, and yet I am sure that you will agree with me that the position was very difficult, and that there was nothing more which I could do.
