"You're too late. She's my wife." "No, she's your widow." His revolver cracked, and I saw the blood spurt from the front of Woodley's waistcoat. He s… - Arthur Conan Doyle

Sherlock Holmes closed his eyes and placed his elbows upon the arms of his chair, with his finger-tips together. “The ideal reasoner,” he remarked, “would, when he had once been shown a single fact in all its bearings, deduce from it not only all the chain of events which led up to it but also all the results which would follow from it. As Cuvier could correctly describe a whole animal by the contemplation of a single bone, so the observer who has thoroughly understood one link in a series of incidents should be able to accurately state all the other ones, both before and after. We have not yet grasped the results which the reason alone can attain to. Problems may be solved in the study which have baffled all those who have sought a solution by the aid of their senses. To carry the art, however, to its highest pitch, it is necessary that the reasoner should be able to utilise all the facts which have come to his knowledge; and this in itself implies, as you will readily see, a possession of all knowledge, which, even in these days of free education and encyclopaedias, is a somewhat rare accomplishment. It is not so impossible, however, that a man should possess all knowledge which is likely to be useful to him in his work, and this I have endeavoured in my case to do.

You know my method. It is founded upon the observation of trifles.

It is a great thing to start life with a small number of really good books which are your very own. You may not appreciate them at first. You may pine for your novel of crude and unadulterated adventure. You may, and will, give it the preference when you can. But the dull days come, and the rainy days come, and always you are driven to fill up the chinks of your reading with the worthy books which wait so patiently for your notice. And then suddenly, on a day which marks an epoch in your life, you understand the difference. You see, like a flash, how the one stands for nothing, and the other for literature. From that day onwards you may return to your crudities, but at least you do so with some standard of comparison in your mind. You can never be the same as you were before. Then gradually the good thing becomes more dear to you; it builds itself up with your growing mind; it becomes a part of your better self, and so, at last, you can look, as I do now, at the old covers and love them for all that they have meant in the past.
