the two men sat sipping and smoking reflectively for some minutes before Dyson began.
“Let me see,” he said at last, “we were at the inquest, weren’t we? No, we had done with that. Ah, I remember. I was telling you that on the whole I had been successful in my inquiries, investigation, or whatever you like to call it, into the matter. Wasn‘t that where I left off?”
“Yes, that was it. To be precise, I think ‘though’ was the last word you said on the matter.”
“Exactly. I have been thinking it all over since the other night, and I have come to the conclusion that that ‘though’ is a very big ‘though’ indeed. Not to put too fine a point on it, I have had to confess that what I found out, or thought I found out, amounts in reality to nothing. I am as far away from the heart of the case as ever. However, I may as well tell you what I do know. You may remember my saying that I was impressed a good deal by some remarks of one of the doctors who gave evidence at the inquest. Well, I determined that my first step must be to try if I could get something more definite and intelligible out of that doctor. Somehow or other I managed to get an introduction to the man, and he gave me an appointment to come and see him. He turned out to be a pleasant, genial fellow; rather young and not in the least like the typical medical man, and he began the conference by offering me whisky and cigars. I didn’t think it worth while to beat about the bush, so I began by saying that part of his evidence at the Harlesden Inquest struck me as very peculiar, and I gave him the printed report, with the sentences in question underlined. He just glanced at the slip, and gave me a queer look. ‘It struck you as peculiar, did it?’ said he. ‘Well, you must remember that the Harlesden case was very peculiar. In fact, I think I may safely say that in some features it was unique—quite unique.’ ‘Quite so,’ I replied, ‘and that’s exactly why it interests me, and why I want to know more about it. And I thought that if anybody could give me any information it would be you. What is your opinion of the matter?’
“It was a pretty downright sort of question, and my doctor looked rather taken aback.
“‘Well,’ he said, ‘as I fancy your motive in inquiring into the question must be mere curiosity, I think I may tell you my opinion with tolerable freedom. So, Mr., Mr. Dyson? if you want to know my theory, it is this: I believe that Dr. Black killed his wife.’
“‘But the verdict,’ I answered, ‘the verdict was given from your own evidence.’
“‘Quite so; the verdict was given in accordance with the evidence of my colleague and myself, and, under the circumstances, I think the jury acted very sensibly. In fact, I don’t see what else they could have done. But I stick to my opinion, mind you, and I say this also. I don’t wonder at Black’s doing what I firmly believe he did. I think he was justified.’
“‘Justified! How could that be?’ I asked. I was astonished, as you may imagine, at the answer I had got. The doctor wheeled round his chair and looked steadily at me for a moment before he answered.
“‘I suppose you are not a man of science yourself? No; then it would be of no use my going into detail. I have always been firmly opposed myself to any partnership between physiology and psychology. I believe that both are bound to suffer. No one recognizes more decidedly than I do the impassable gulf, the fathomless abyss that separates the world of consciousness from the sphere of matter. We know that every change of consciousness is accompanied by a rearrangement of the molecules in the grey matter; and that is all. What the link between them is, or why they occur together, we do not know, and most authorities believe that we never can know. Yet, I will tell you that as I did my work, the knife in my hand, I felt convinced, in spite of all theories, that what lay before me was not the brain of a dead woman—not the brain of a human being at all. Of course I saw the face; but it was quite placid, devoid of all expression. It must have been a beautiful face, no doubt, but I can honestly say that I would not have looked in that face when there was life behind it for a thousand guineas, no, nor for twice that sum.’
“‘My dear sir,’ I said, ‘you surprise me extremely. You say that it was not the brain of a human being. What was it then?’
“‘The brain of a devil.’ He spoke quite coolly, and never moved a muscle. ‘The brain of a devil,’ he repeated, ‘and I have no doubt that Black found some way of putting an end to it. I don’t blame him if he did. Whatever Mrs. Black was, she was not fit to stay in this world. Will you have anything more? No? Good-night, good-night.’
“It was a queer sort of opinion to get from a man of science, wasn’t it? When he was saying that he would not have looked on that face when alive for a thousand guineas, or two thousand guineas, I was thinking of the face I had seen, but I said nothing. I went again to Harlesden, and passed from one shop to another, making small purchases, and trying to find out whether there was anything about the Blacks which was not already common property, but there was very little to hear. One of the tradesmen to whom I spoke said he had known the dead woman well; she used to buy of him such quantities of grocery as were required for their small household, for they never kept a servant, but had a charwoman in occasionally, and she had not seen Mrs. Black for months before she died. According to this man Mrs. Black was ‘a nice lady,’ always kind and considerate, and so fond of her husband and he of her, as every one thought. And yet, to put the doctor’s opinion on one side, I knew what I had seen. And then after thinking it all over, and putting one thing with another, it seemed to me that the only person likely to give me much assistance would be Black himself, and I made up my mind to find him. Of course he wasn’t to be found in Harlesden; he had left, I was told, directly after the funeral. Everything in the house had been sold, and one fine day Black got into the train with a small portmanteau, and went, nobody knew where. It was a chance if he were ever heard of again, and it was by a mere chance that I came across him at last. I was walking one day along Gray’s Inn Road, not bound for anywhere in particular, but looking about me, as usual, and holding on to my hat, for it was a gusty day in early March, and the wind was making the treetops in the Inn rock and quiver. I had come up from the Holborn end, and I had almost got to Theobald’s Road when I noticed a man walking in front of me, leaning on a stick, and to all appearance very feeble. There was something about his look that made me curious, I don’t know why, and I began to walk briskly with the idea of overtaking him, when of a sudden his hat blew off and came bounding along the pavement to my feet. Of course I rescued the hat, and gave it a glance as I went towards its owner. It was a biography in itself; a Piccadilly maker’s name in the inside, but I don’t think a beggar would have picked it out of the gutter. Then I looked up and saw Dr. Black of Harlesden waiting for me. A queer thing, wasn’t it? But, Salisbury, what a change! When I saw Dr. Black come down the steps of his house at Harlesden he was an upright man, walking firmly with well-built limbs; a man, I should say, in the prime of his life. And now before me there crouched this wretched creature, bent and feeble, with shrunken cheeks, and hair that was whitening fast, and limbs that trembled and shook together, and misery in his eyes. He thanked me for bringing him his hat, saying, ‘I don’t think I should ever have got it, I can’t run much now. A gusty day, sir, isn’t it?’ and with this he was turning away, but by little and little I contrived to draw him into the current of conversation, and we walked together eastward. I think the man would have been glad to get rid of me; but I didn’t intend to let him go, and he stopped at last in front of a miserable house in a miserable street. It was, I verily believe, one of the most wretched quarters I have ever seen: houses that must have been sordid and hideous enough when new, that had gathered foulness with every year, and now seemed to lean and totter to their fall. ‘I live up there,’ said Black, pointing to the tiles, ‘not in the front—in the back. I am very quiet there. I won’t ask you to come in now, but perhaps some other day—’ I caught him up at that, and told him I should be only too glad to come and see him. He gave me an odd sort of glance, as if he were wondering what on earth I or anybody else could care about him, and I left him fumbling with his latch-key. I think you will say I did pretty well when I tell you that within a few weeks I had made myself an intimate friend of Black’s. I shall never forget the first time I went to his room; I hope I shall never see such abject, squalid misery again. The foul paper, from which all pattern or trace of a pattern had long vanished, subdued and penetrated with the grime of the evil street, was hanging
