“And where did he say that he lived?”

“Among the old houses on the hillside—the stone huts where the old folk used to live.”

“But how about his food?”

“Selden found out that he has got a lad who works for him and brings him all he needs. I dare say he goes to Coombe Tracey for what he wants.”

“Very good, Barrymore. We may talk further of this some other time.” When the butler had gone I walked over to the black window, and I looked through a blurred pane at the driving clouds and at the tossing outline of the wind-swept trees. It is a wild night indoors, and what must it be in a stone hut upon the moor. What passion of hatred can it be which leads a man to lurk in such a place at such a time! And what deep and earnest purpose can he have which calls for such a trial! There, in that hut upon the moor, seems to lie the very centre of that problem which has vexed me so sorely. I swear that another day shall not have passed before I have done all that man can do to reach the heart of the mystery.

The extract from my private diary which forms the last chapter has brought my narrative up to the 18th of October, a time when these strange events began to move swiftly towards their terrible conclusion. The incidents of the next few days are indelibly graven upon my recollection, and I can tell them without reference to the notes made at the time. I start then from the day which succeeded that upon which I had established two facts of great importance, the one that Mrs. Laura Lyons of Coombe Tracey had written to Sir Charles Baskerville and made an appointment with him at the very place and hour that he met his death, the other that the lurking man upon the moor was to be found among the stone huts upon the hill-side. With these two facts in my possession I felt that either my intelligence or my courage must be deficient if I could not throw some further light upon these dark places.

I had no opportunity to tell the baronet what I had learned about Mrs. Lyons upon the evening before, for Dr. Mortimer remained with him at cards until it was very late. At breakfast, however, I informed him about my discovery, and asked him whether he would care to accompany me to Coombe Tracey. At first he was very eager to come, but on second thoughts it seemed to both of us that if I went alone the results might be better. The more formal we made the visit the less information we might obtain. I left Sir Henry behind, therefore, not without some prickings of conscience, and drove off upon my new quest.

When I reached Coombe Tracey I told Perkins to put up the horses, and I made inquiries for the lady whom I had come to interrogate. I had no difficulty in finding her rooms, which were central and well appointed. A maid showed me in without ceremony, and as I entered the sitting-room a lady, who was sitting before a Remington typewriter, sprang up with a pleasant smile of welcome. Her face fell, however, when she saw that I was a stranger, and she sat down again and asked me the object of my visit.
