“Do you know, Watson," said he, "that it is one of the curses of a mind with a turn like mine that I must look at everything with reference to my own special subject. You look at these scattered houses, and you are impressed by their beauty. I look at them, and the only thought which comes to me is a feeling of their isolation and of the impunity with which crime may be committed there.”

“Are they not fresh and beautiful?" [Watson] cried...Holmes shook his head gravely."... You look at these scattered houses, and you are impressed bu their beauty. I look at them, and the only thought which comes to me is a feeling of their isolation and of the impunity with which crime may be committed here... They always filled me with a certain horror. It is my belief, Watson... that the lowest and vilest alleys in London do not present a more dreadful record of sin than does the smiling and beauty of the countryside... But the reason is obvious. The pressure of public opinion can do in the town what the law cannot accomplish.”

“It's a very cheery thing to come into London by any of these lines which run high and allow you to look down upon the houses like this."I thought he was joking, for the view was sordid enough, but he soon explained himself."Look at those big, isolated clumps of buildings rising up above the slates, like brick islands in a lead-coloured sea.""The board-schools.""Light-houses, my boy! Beacons of the future! Capsules with hundreds of bright little seeds in each, out of which will spring the wiser, better England of the future.”

“Now, Watson,' said Holmes, (...) 'you'll come with me, won't you?''If I can be of use.''Oh, a trusty comrade is always of use. And a chronicler still more so. My room at The Cedars is a double-bedded one.'(...)'You have a grand gift of silence, Watson,' said he. 'It makes you quite invaluable as a companion. Pon my word, it is a great thing for me to have someone to talk to, for my own thoughts are not over-pleasant.”

“All right, Watson. Don’t look so scared,” he muttered in a very weak voice. “It’s not as bad as it seems.”“Thank God for that!”“I’m a bit of a single-stick expert, as you know. I took most of them on my guard. It was the second man that was too much for me.”“What can I do, Holmes? Of course, it was that damned fellow who set them on. I’ll go and thrash the hide off him if you give the word.”“Good old Watson!(...)”

“I rose to go, but Holmes caught me by my wrist and pushed me back into my chair. 'It is both, or none,' said he. 'You may say before this gentleman anything which you may say to me.”

“I should prefer that you do not mention my name at all in connection with this case, as I choose to be only associated with those crimes which present some difficulty in their solution.”
