"What science do you mean?""The science of the great city; the physiology of London; literally and metaphysically the greatest subject that the mind of man can conceive. What an admirable salmi this us; undoubtedly the final end of the pheasant. Yet I feel sometimes positively overwhelmed with the thought of the vastness and complexity of London. Paris a man may get to understand thoroughly with a reasonable amount of study; but London is always a mystery. In Paris you may say: 'Here live the actresses, here the Bohemians, and the Ratés'; but it is different in London. You may point out a street, correctly enough, as the abode of washerwomen; but, in that second floor, a man may be studying Chaldee roots, and in the garret over the way a forgotten artist is dying by inches.""I see you are Dyson, unchanged and unchangeable," said Salisbury, slowly sipping his Chianti. "I think you are misled by a too fervid imagination; the mystery of London exists only in your fancy. It seems to me a dull place enough. We seldom hear of a really artistic crime in London, whereas I believe Paris abounds in that sort of thing.""Give me some more wine. Thanks. You are mistaken, my dear fellow, you are really mistaken. London has nothing to be ashamed of in the way of crime. Where we fail is for want of Homers, not Agamemnons. Carent quia vate sacro, you know.""I recall the quotation. But I don't think I quite follow you.""Well, in plain language, we have no good writers in London who make a speciality of that kind of thing. Our common reporter is a dull dog; every story that he has to tell is spoilt in the telling. His idea of horror and of what excites horror is so lamentably deficient. Nothing will content the fellow but blood, vulgar red blood, and when he can get it he lays it on thick, and considers that he has produced a telling article. It's a poor notion. And, by some curious fatality, it is the most commonplace and brutal murders which always attract the most attention and get written up the most. For instance, I dare say that you never heard of the Harlesden case?""No; no, I don't remember anything about it.""Of course not. And yet the story is a curious one. I will tell you over our coffee. Harlesden, you know, or I expect you don't know, is quite on the out-quarters of London; something curiously different from your fine old crusted suburb like Norwood or Hampstead, different as each of these is from the other. Hampstead, I mean, is where you look for the head of your great China house with his three acres of land and pine-houses, though of late there is the artistic substratum; while Norwood is the home of the prosperous middle-class family who took the house 'because it was near the Palace, ' and sickened of the Palace six months afterwards; but Harlesden is a place of no character. It's too new to have any character as yet. There are the rows of red houses and the rows of white houses and the bright green Venetians, and the blistering.doorways, and the little backyards they call gardens, and a few feeble shops, and then, just as you think you're going to grasp the physiognomy of the settlement, it all melts away."
