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 in mouldering pennons from the wall. Only at the end of the room was it possible to stand upright, and the sight of the wretched bed and the odour of corruption that pervaded the place made me turn faint and sick. Here I found him munching a piece of bread; he seemed surprised to find that I had kept my promise, but he gave me his chair and sat on the bed while we talked. I used to go to see him often, and we had long conversations together, but he never mentioned Harlesden or his wife. I fancy that he supposed me ignorant of the matter, or thought that if I had heard of it, I should never connect the respectable Dr. Black of Harlesden with a poor garreteer in the backwoods of London. He was a strange man, and as we sat together smoking, I often wondered whether he were mad or sane, for I think the wildest dreams of Paracelsus and the Rosicrucians would appear plain and sober fact compared with the theories I have heard him earnestly advance in that grimy den of his. I once ventured to hint something of the sort to him. I suggested that something he had said was in flat contradiction to all science and all experience. 'No,' he answered, 'not all experience, for mine counts for something. I am no dealer in unproved theories; what I say I have proved for myself, and at a terrible cost. There is a region of knowledge which you will never know, which wise men seeing from afar off shun like the plague, as well they may, but into that region I have gone. If you knew, if you could even dream of what may be done, of what one or two men have done in this quiet world of ours, your very soul would shudder and faint within you. What you have heard from me has been but the merest husk and outer covering of true science—that science which means death, and that which is more awful than death, to those who gain it. No, when men say that there are strange things in the world, they little know the awe and the terror that dwell always with them and about them.' There was a sort of fascination about the man that drew me to him, and I was quite sorry to have to leave London for a month or two; I missed his odd talk. A few days after I came back to town I thought I would look him up, but when I gave the two rings at the bell that used to summon him, there was no answer. I rang and rang again, and was just turning to go away, when the door opened and a dirty woman asked me what I wanted. From her look I fancy she took me for a plain-clothes officer after one of her lodgers, but when I inquired if Mr. Black were in, she gave me a stare of another kind. 'There's no Mr. Black lives here,' she said. 'He's gone. He's dead this six weeks. I always thought he was a bit queer in his head, or else had been and got into some trouble or other. He used to go out every morning from ten till one, and one Monday morning we heard him come in, and go into his room and shut the door, and a few minutes after, just as we was a-sitting down to our dinner, there was such a scream that I thought I should have gone right off. And then we heard a stamping, and down he came, raging and cursing most dreadful, swearing he had been robbed of something that was worth millions. And then he just dropped down in the passage, and we thought he was dead. We got him up to his room, and put him on his bed, and I just sat there and waited, while my 'usband he went for the doctor. And there was the winder wide open, and a little tin box he had lying on the floor open and empty, but of course nobody could possible have got in at the winder, and as for him having anything that was worth anything, it's nonsense, for he was often weeks and weeks behind with his rent, and my 'usband he threatened often and often to turn him into the street, for, as he said, we've got a living to myke like other people—and, of course, that's true; but, somehow, I didn't like to do it, though he was an odd kind of a man, and I fancy had been better off. And then the doctor came and looked at him, and said as he couldn't do nothing, and that night he died as I was a-sitting by his bed; and I can tell you that, with one thing and another, we lost money by him, for the few bits of clothes as he had were worth next to nothing when they came to be sold.' I gave the woman half a sovereign for her trouble, and went home thinking of Dr. Black and the epitaph she had made him, and wondering at his strange fancy that he had been robbed. I take it that he had very little to fear on that score, poor fellow; but I suppose that he was really mad, and died in a sudden access of his mania. His landlady said that once or twice when she had had occasion to go into his room (to dun the poor wretch for his rent, most likely), he would keep her at the door for about a minute, and that when she came in she would find him putting away his tin box in the corner by the window; I suppose he had become possessed with the idea of some great treasure, and fancied himself a wealthy man in the midst of all his misery.
'Well, Dyson, I must say that I think you have contrived to surround the whole thing with a mystery of your own making. I go for the doctor's solution: Black murdered his wife, being himself in all probability an undeveloped lunatic.'
'What? Do you believe, then, that this woman was something too awful, too terrible to be allowed to remain on the earth? You will remember that the doctor said it was the brain of a devil?'
'Yes, yes, but he was speaking, of course, metaphorically. It's really quite a simple matter if you only look at it like that.'
'Ah, well, you may be right; but yet I am sure you are not. Well, well, it's no good discussing it any more. A little more Benedictine? That's right; try some of this tobacco. Didn't you say that you had been bothered by something—something which happened that night we dined together?'
'Yes, I have been worried, Dyson, worried a great deal. I——But it's such a trivial matter—indeed, such an absurdity—that I feel ashamed to trouble you with it.'
'Never mind, let's have it, absurd or not.'
With many hesitations, and with much inward resentment of the folly of the thing, Salisbury told his tale, and repeated reluctantly the absurd intelligence and the absurder doggerel of the scrap of paper, expecting to hear Dyson burst out into a roar of laughter.
'Isn't it too bad that I should let myself be bothered by such stuff as that?' he asked, when he had stuttered out the jingle of once, and twice, and thrice.
Dyson listened to it all gravely, even to the end, and meditated for a few minutes in silence.
'Yes,' he said at length, 'it was a curious chance, your taking shelter in that archway just as those two went
