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 tree-tops 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 Rosicrucians6 would appear plain and sober fact compared with the theories I have heard him earnestly advance in that grimy den of his.
