“Well, as I told you last night, I had a bad fire in my house at Bombay. Half of it was burned down, and, among other things, my pathological collection was largely destroyed. What you see are the poor remains of it. The hand of the hillman went with the rest, but I gave the matter no particular thought at the time. That was six years ago. “Four years ago--two years after the fire--I was awakened one night by a furious tugging at my sleeve. I sat up under the impression that my favourite mastiff was trying to arouse me. Instead of this, I saw my Indian patient of long ago, dressed in the long grey gown which was the badge of his people. He was holding up his stump and looking reproachfully at me. He then went over to my bottles, which at that time I kept in my room, and he examined them carefully, after which he gave a gesture of anger and vanished. I realised that he had just died, and that he had come to claim my promise that I should keep his limb in safety for him. “Well, there you have it all, Dr. Hardacre. Every night at the same hour for four years this performance has been repeated. It is a simple thing in itself, but it has worn me out like water dropping on a stone. It has brought a vile insomnia with it, for I cannot sleep now for the expectation of his coming. It has poisoned my old age and that of my wife, who has been the sharer in this great trouble. But there is the breakfast gong, and she will be waiting impatiently to know how it fared with you last night. We are both much indebted to you for your gallantry, for it takes something from the weight of our misfortune when we share it, even for a single night, with a friend, and it reassures us as to our sanity, which we are sometimes driven to question.” This was the curious narrative which Sir Dominick confided to me--a story which to many would have appeared to be a grotesque impossibility, but which, after my experience of the night before, and my previous knowledge of such things, I was prepared to accept as an absolute fact. I thought deeply over the matter, and brought the whole range of my reading and experience to bear upon it. After breakfast, I surprised my host and hostess by announcing that I was returning to London by the next train. “My dear doctor,” cried Sir Dominick in great distress, “you make me feel that I have been guilty of a gross breach of hospitality in intruding this unfortunate matter upon you. I should have borne my own burden.” “It is, indeed, that matter which is taking me to London,” I answered; “but you are mistaken, I assure you, if you think that my experience of last night was an unpleasant one to me. On the contrary, I am about to ask your permission to return in the evening and spend one more night in your laboratory. I am very eager to see this visitor once again.”
