“Now, Watson,” said Holmes, as a tall dog-cart dashed up through the gloom, throwing out two golden tunnels of yellow light from its side lanterns. “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.”

“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.”

“My dear fellow, you may laugh, but I give you my word that I shall be very glad to have you back safe and sound in Baker Street once more.- Holmes, to Watson.”

“I felt Holmes's hand steal into mine and give me a reassuring shake.- Watson”

“Watson: When do we start?Holmes: You are not coming.Watson: Then you are not going. I give you my word of honour - and I never broke it in my life - that I will take a cab straight to the police station and give you away unless you let me share this adventure with you.”

A fool takes in all the lumber of every sort that he comes across, so that the knowledge which might be useful to him gets crowded out, or at best is jumbled up with a lot of other things, so that he has difficulty in laying his hands upon it. Now the skilful workman is very careful indeed as to what he takes into his brain-attic. He will have nothing but the tools which may help him in doing his work, but of these he has a large assortment, and all in most perfect order. It is a mistake to think that that that little room has elastic walls and can distend to any extent. Depend upon it there comes a time when for every addition of knowledge you forget something that you knew before. It is of the highest importance, therefore, not to have useless facts elbowing out the useful ones.’‘But the Solar System!’ I protested.‘What the deuce is it to me?’ he interrupted impatiently: ‘you say that we go round the sun. If we went round the moon it would not make a pennyworth of difference to me or to my work.”

“Very sorry to knock you up, Watson,' said he [Holmes], 'but it is a common lot this morning. Mrs Hudson has been knocked up, she retorted upon me, and I on you.”
