“The whole force of the State is at your back if you should need it. I’m afraid that all the queen’s horses and all the queen’s men cannot avail in this matter.”

“WATSON: Then you are yourself inclining to the supernatural explanation.     HOLMES: if Dr. Mortimer's surmise should be correct, and we are dealing with forces outside the ordinary laws of Nature, there is an end of our investigation. But we are bound to exhaust all other hypotheses before falling back upon this one.”

“I should be very much obliged if you would slip your revolver into your pocket. An Eley's No. 2 is an excellent argument with gentlemen who can twist steel pokers into knots. That and a tooth-brush are, I think, all that we need.”

“Some of you rich men have to be taught that all the world cannot be bribed into condoning your offences.\”

“It was surely well for man that he came late in the order of creation. There were powers abroad in earlier days which no courage and no mechanism of his could have met. What could his sling, his throwing-stick, or his arrow avail him against such forces as have been loose tonight? Even with a modern rifle it would be all odds on the monster.”

“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.”

“I care not how humble your bookshelf may be, or how lonely the room which it adorns. Close the door of that room behind you, shut off with it all the cares of the outer world, plunge back into the soothing company of the great dead, and then you are through the magic portal into that fair land whither worry and vexation can follow you no more. You have left all that is vulgar and all that is sordid behind you. There stand your noble, silent comrades, waiting in their ranks. Pass your eye down their files. Choose your man. And then you have but to hold up your hand to him and away you go together into dreamland”
