On glancing over my notes of the seventy odd cases in which I have during the last eight years studied the methods of my friend Sherlock Holmes, I find many tragic, some comic, a large number merely strange, but none commonplace; for, working as he did rather for the love of his art than for the acquirement of wealth, he refused to associate himself with any investigation which did not tend towards the unusual, and even the fantastic.

The emotional qualities are antagonistic to clear reasoning.

I think you want a little unofficial help. Three undetected murders in one year won't do, Lestrade. But you handled the Molesey Mystery with less than your usual - that's to say, you handled it fairly well.

"There are one or two elementary rules to be observed in the way of handling patients," he remarked, seating himself on the table and swinging his legs. "The most obvious is that you must never let them see that you want them. It should be pure condescension on your part seeing them at all; and the more difficulties you throw in the way of it, the more they think of it. Break your patients in early, and keep them well to heel."

Violence recoils on the violent.

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