Sherlock Holmes took his bottle from the corner of the mantel-piece, and his hypodermic syringe from its neat morocco case. With his long, white, nervous fingers he adjusted the delicate needle, and rolled back his left shirt-cuff. For some little time his eyes rested thoughtfully upon the sinewy forearm and wrist, all dotted and scarred with innumerable puncture-marks. Finally, he thrust the sharp point home, pressed down the tiny piston, and sank back into the velvet-lined armchair with a long sigh of satisfaction.
Far away on the path we saw Sir Henry looking back, his face white in the moonlight, his hands raised in horror, glaring helplessly at the frightful thing which was hunting him down. But that cry of pain from the hound had blown all our fears to the winds. If he was vulnerable he was mortal, and if we could wound him we could kill him. Never have I seen a man run as Holmes ran that night.
As a rule, said Holmes, the more bizarre a thing is the less mysterious it proves to be. It is your commonplace, featureless crimes which are really puzzling, just as a commonplace face is the most difficult to identify.
I have mastered the principles of several religions. They have all shocked me by the violence which I should have to do to my reason to accept the dogmas of any one of them.
I could not rest, Watson, I could not sit quiet in my chair, if I thought that such a man as Professor Moriarty were walking the streets of London unchallenged.
Well, I'm a bacteriologist, you know. I live in a nine-hundred-diameter microscope. I can hardly claim to take serious notice of anything that I can see with my naked eye.
It has always seemed to me that so long as you produce your dramatic effect, accuracy of detail matters little. I have never striven for it and I have made some bad mistakes in consequence. What matter if I hold my readers?
Come what may, I am bound to think that all things are ordered for the best; though when the good is a furlong off, and we with our beetle eyes can only see three inches, it takes some confidence in general principles to pull us through.
In shape they were like horrible toads, and moved in a succession of springs, but in size they were of an incredible bulk, larger than the largest elephant. We had never before seen them save at night, and indeed they are nocturnal animals save when disturbed in their lairs, as these had been. We now stood amazed at the sight, for their blotched and warty skins were of a curious fish-like iridescence, and the sunlight struck them with an ever-varying rainbow bloom as they moved.
One dumb-bell, Watson! Consider an athlete with one dumb-bell. Picture to yourself the unilateral development - the imminent danger of a spinal curvature. Shocking, Watson, shocking!
Perhaps, when a man has special knowledge and special powers like my own, it rather encourages him to seek a complex explanation when a simpler one is at hand.
