I was struck, too, by the immovable determination to compass her own ends at any and every risk, which was manifested by this incident; and, wondering more and more as to what had been the nature of the offence for which Mr. Pollard sought to make reparation in his will, I only waited for a moment of leisure in order to make another effort at enlightenment by a second study of the prayer-book which my dying friend had placed so earnestly in my hands. It came, as I supposed, about eight o'clock that evening. The special duties of the day were done, and I knew of nothing else that demanded my attention. I therefore took the book from my pocket, where I had fortunately kept it, and was on the point of opening its pages, when there came a ring at the door-bell below. As I have said before, my landlady was away. I consequently went to the door myself, where I was met by an unexpected visitor in the shape of the idiot boy, Colwell. Somewhat disconcerted at the sight of a face so repugnant to me, I was still more thrown off my balance when I heard his errand. He had been sent, he said, by a man who had been thrown from his wagon on the north road, and was now lying in a dying condition inside the old mill, before which he was picked up. Would I come and see him? He had but an hour or so to live, and wished very much for a clergyman's consolation. It was a call any thing but agreeable to me. I was tired; I was interested in the attempt which I was about to make to solve a mystery that was not altogether disconnected with my own personal welfare, and--let me acknowledge it, since events have proved I had reason to fear this spot--I did not like the old mill. But I was far from conceiving what a wretched experience lay before me, nor did the fact that the unwelcome request came through the medium of an imbecile arouse any suspicion in my mind as to the truth of the message he brought. For, foolish as he is in some regards, his reliability as an errand-boy is universally known, while his partiality for roaming, as well as for excitements of all kinds, fully accounted for the fact of his being upon the scene of accident. I had, then, nothing but my own disinclinations to contend with, and these, strong as they were, could not, at that time, and in the mood which my late experience had induced, long stand in the way of a duty so apparent. I consequently testified my willingness to go to the mill, and in a few minutes later set out for that spot with a mind comparatively free from disagreeable forebodings. But as we approached the mill, and I caught a glimpse of its frowning walls glooming so darkly from out the cluster of trees that environed them, I own that a sensation akin to that which had been awakened in me by Mrs. Pollard's threats, and the portentous darkness of her sombre mansion, once again swept with its chilling effect over my nerves.
