Dr. John Watson

"It was in the spring of the year 1888 that Holmes called upon me."

"Providence might throw a clue into our way."

"The facts seem to speak for themselves."

"That is indeed most singular."

"All this is very mysterious and rather grim."

"That is indeed a curious case, and one which presents some features of interest."

"The mystery deepens."

"I am endeavouring to be factual and not to be influenced by sentiment"

"London is a cesspool into which all the loungers and idlers of the Empire are irresistibly drained"

"The lowest and vilest alleys of London do not present a more dreadful record of sin than does the smiling and beautiful countryside"

"Life is infinitely stranger than anything which the mind of man could invent"

"The strange thing about the enterprise is that it was so innocent at the beginning"

"You have extraordinary genius and powers of observation"

"Evil comes not from without but from within ourselves"

"Some of my most successful cases have come through my fellow lodger"

"The world is not yet sufficiently advanced to see the wisdom of such actions"

"I found Watson in his old sitting-room which he has hardly ever quitted"

"Now that the matter has been so happily resolved, I do not see why I should be withheld from publication"

"I am afraid that I cannot do justice to this part of my narrative."

"You have brought detection as near an exact science as ever will be brought in this world."

"A long series of sterile weeks occurred, in which I tasted only too well the truth of my observation."

"The matter was too serious for any hesitation on my part."

"I felt powerless and unhappy, sitting at home, even in the society of the best wife in the world."

"The truth of the matter was just as I had deduced in every essential particular."

"It is well to have it all in writing."

"The world is indeed full of queer things, and we who are fortunate enough to live in it get our share of the queerness."

"A single night's investigation has not restored my health."
