“I shall never do that,' I answered; 'you have brought detection as near an exact science as it ever will be brought in this world.”

“There are no crimes and no criminals in these days. What is the use of having brains in our profession? I know well that I have it in me to make my name famous. No man lives or has ever lived who has brought the same amount of study and of natural talent to the detection of crime which I have done. And what is the result? There is no crime to detect, or, at most, some bungling villainy with a motive so transparent that even a Scotland Yard official can see through it.”

“Detection is, or ought to be, an exact science and should be treated in the same cold and unemotional manner. You have attempted to tinge it with romanticism, which produces much the same effect as if you worked a love-story ... Some facts should be suppressed, or, at least, a just sense of proportion should be observed in treating them. The only point in the case which deserved mention was the curious analytical reasoning from effects to causes, by which I succeeded in unravelling it.''—Sherlock Holmes on John Watson's "pamphlet", "A Study in Scarlet".”

“The affair seems absurdly trifling, and yet I dare call nothing trivial when I reflect that some of my most classic cases have had the least promising commencement. You will remember, Watson, how the dreadful business of the Abernetty family was first brought to my notice by the depth which the parsley had sunk into the butter upon a hot day.”

“I suppose I shall have to compound a felony, as usual.”

“Holy men? Holy cabbages! Holy bean-pods! What do they do but live and suck in sustenance and grow fat? If that be holiness, I could show you hogs in this forest who are fit to head the calendar. Think you it was for such a life that this good arm was fixed upon my shoulder, or that head placed upon your neck? There is work in the world, man, and it is not by hiding behind stone walls that we shall do it.”

“By the way, Doctor, I shall want your cooperation.''I shall be delighted.''You don't mind breaking the law?''Not in the least.''Nor running a chance of arrest?''Not in a good cause.''Oh, the cause is excellent!''Then I am your man.''I was sure that I might rely on you.”
