“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.”

“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.”

“It is my belief, Watson, founded upon my experience, that the lowest and vilest alleys in London do not present a more dreadful record of sin than does the smiling and beautiful countryside.”

“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.”

“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.”

“How sweet the morning air is! See how that one little cloud floats like a pink feather from some gigantic flamingo. Now the red rim of the sun pushes itself over the London cloud-bank. It shines on a good many folk, but on none, I dare bet, who are on a stranger errand than you and I. How small we feel with our petty ambitions and strivings in the presence of the great elemental forces of Nature!”
