He is the Napoleon of crime, Watson. He is the organizer of half that is evil and of nearly all that is undetected in this great city, he is a genius, a philosopher, an abstract thinker. He has a brain of the first order. He sits motionless, like a spider in the center of its web, but that web has a thousand radiations, and he knows well every quiver of each of them. He does little himself. He only plans.
Arthur Conan Doyle,
The Memoirs of Sherlock Holmes
