Of course he’s Richard Brook. There is no Moriarty.
Did you almost start to wonder if I was real? Did I nearly get you?
“His position is unique. He has made it for himself. There has never been anything like it before, nor will be again. He has the tidiest and most orderly brain, with the greatest capacity for storing facts, of any man living. The same great powers which I have turned into the detection of crime he has used for this particular business. The conclusions of every department are passed to him, and he is the central exchange, the clearing-house, which makes out the balance. All other men are specialists, but his specialism is omniscience. We will suppose that a minister needs information as to a point which involves the Navy, India, Canada and the bimetallic question; he could get his separate advices from various departments upon each, but only Mycroft can focus them all, and say offhand how each factor would affect the other. They began by using him as a short-cut, a convenience; now he has made himself an essential. In that great brain of his everything is pigeon-holed and can be handed out in an instant. Again and again his word has decided the national policy. He lives in it.”
“They tell us that Suicide is the greatest piece of Cowardice … that Suicide is wrong; when it is quite obvious that there is nothing in this world to which every man has a more unassailable title than to his own life and person.” — Arthur Schopenhauer
