“I could not rest, Watson, I could not sit quiet in my chair, if I thought that such a man as Professor Moriarty were walking the streets of London unchallenged.”

“I am a brain, Watson. The rest of me is a mere appendix.”

“And here it is that I miss my Watson. By cunning questions and ejaculations of wonder he could elevate my simple art, which is but systematized common sense, into a prodigy. When I tell my own story I have no such aid.”

“You would not call me a marrying man, Watson?""No, indeed!""You'll be interested to hear that I'm engaged.""My dear fellow! I congrat-""To Milverton's housemaid.""My dear Holmes!""I wanted information, Watson.”

“The London criminal is certainly a dull fellow. Look out of this window, Watson. See how the figures loom up, are dimly seen, and then blend once more into the cloudbank. The thief or the murderer could roam London on such a day as the tiger does the jungle, unseen until he pounces, and then evident only to his victim. There have been numerous petty thefts. This great and sombre stage is set for something more worthy than that. It is fortunate for this community that I am not a criminal.”

“Should I ever marry, Watson, I should hope to inspire my wife with some feeling which would prevent her from being walked off by a housekeeper when my corpse was lying within a few yards of her.”

“We're at close grips at last," said Holmes as we walked together across the moor. "What a nerve the fellow has! How he pulled himself together in the face of what must have been a paralyzing shock when he found that the wrong man had fallen a victim to his plot. I told you in London, Watson, and I tell you now again, that we have never had a foeman more worthy of our steel.”
