I had observed some newspaper comment at the time, but I was exceedingly preoccupied by that little affair of the Vatican cameos, and in my anxiety to oblige the Pope I lost touch with several interesting English cases. This article, you say, contains all the public facts?"
"Then let me have the private ones." He leaned back, put his finger-tips together, and assumed his most impassive and judicial expression.
"In doing so," said Dr. Mortimer, who had begun to show signs of some strong emotion, "I am telling that which I have not confided to anyone. My motive for withholding it from the coroner's inquiry is that a man of science shrinks from placing himself in the public position of seeming to indorse a popular superstition. I had the further motive that Baskerville Hall, as the paper says, would certainly remain untenanted if anything were done to increase its already rather grim reputation. For both these reasons I thought that I was justified in telling rather less than I knew, since no practical good could result from it, but with you there is no reason why I should not be perfectly frank.
"The moor is very sparsely inhabited, and those who live near each other are thrown very much together. For this reason I saw a good deal of Sir Charles Baskerville. With the exception of Mr. Frankland, of Lafter Hall, and Mr. Stapleton, the naturalist, there are no other men of education within many miles. Sir Charles was a retiring man, but the chance of his illness brought us together, and a community of interests in science kept us so. He had brought back much scientific information from South Africa, and many a charming evening we have spent together discussing the comparative anatomy of the Bushman and the Hottentot.
"Within the last few months it became increasingly plain to me that Sir Charles's nervous system was strained to the breaking point. He had taken this legend which I have read you exceedingly to heart--so much so that, although he would walk in his own grounds, nothing would induce him to go out upon the moor at night. Incredible as it may appear to you, Mr. Holmes, he was honestly convinced that a dreadful fate overhung his family, and certainly the records which he was able to give of his ancestors were not encouraging. The idea of some ghastly presence constantly haunted him, and on more than one occasion he has asked me whether I had on my medical journeys at night ever seen any strange creature or heard the baying of a hound. The latter question he put to me several times, and always with a voice which vibrated with excitement.
"I can well remember driving up to his house in the evening some three weeks before the fatal event. He chanced to be at his hall door. I had descended from my gig and was standing in front of him, when I saw his eyes fix themselves over my shoulder, and stare past me with an expression of the most dreadful horror. I whisked round and had just time to catch a glimpse of something which I took to be a large black calf passing at the head of the drive. So excited and alarmed was he that I was compelled to go down to the spot where the animal had been and look around for it. It was gone, however, and the incident appeared to make the worst impression upon his mind. I stayed with him all the evening, and it was on that occasion, to explain the emotion which he had shown, that he confided to my keeping that narrative which I read to you when first I came. I mention this small episode because it assumes some importance in view of the tragedy which followed, but I was convinced at the time that the matter was entirely trivial and that his excitement had no justification.
"It was at my advice that Sir Charles was about to go to London. His heart was, I knew, affected, and the constant anxiety in which he lived, however chimerical the cause of it might be, was evidently having a serious effect upon his health. I thought that a few months among the distractions of town would send him back a new man. Mr. Stapleton, a mutual friend who was much concerned at his state of health, was of the same opinion.
