“I followed you.'I saw no one.'That is what you may expect to see when I follow you.”

“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.”

“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.”

“By George!" cried the inspector. "How did you ever see that?"Because I looked for it.”

“Perchance you shall, fair sir," said Nigel, "for all that I have seen of you fills me with this desire to go further with you. It is in my mind that we might turn this thing to profit and to honour, for when Sir Robert has spoken to you, I am free to do with you as I will.”

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.
