"It is of the highest importance in the art of detection to be able to recognize, out of a number of facts, which are incidental and which vital. Otherwise your energy and attention must be dissipated instead of being concentrated."
Sherlock Holmes, in "The Reigate Squires"
" Excellent!" I cried.
"Elementary," said he.
Watson and Sherlock Holmes, in "The Adventure of the Crooked Man"
A depleted bank account had caused me to postpone my holiday, and as to my companion, neither the country nor the sea presented the slightest attraction to him. He loved to lie in the very centre of five millions of people, with his filaments stretching out and running through them, responsive to every little rumor or suspicion of unsolved crime. Appreciation of Nature found no place among his many gifts, and his only change was when he turned his mind from the evil-doer of the town to track down his brother of the country.
Watson, in "The Adventure of the Resident Patient"
"But, none the less, my turn that way is in my veins, and may have come with my grandmother, who was the sister of Vernet, the French artist. Art in the blood is liable to take the strangest forms."
Sherlock Holmes, in "The Adventure of the Greek Interpreter"
"My dear Watson," said he, "I cannot agree with those who rank modesty among the virtues. To the logician all things should be seen exactly as they are, and to underestimate one's self is as much a departure from truth as to exaggerate one's own powers."
Sherlock Holmes, in "The Adventure of the Greek Interpreter"
"I said that he was my superior in observation and deduction. If the art of the detective began and ended in reasoning from an arm-chair, my brother would be the greatest criminal agent that ever lived. But he has no ambition and no energy. He will not even go out of his way to verify his own solution, and would rather be considered wrong than take the trouble to prove himself right."
Sherlock Holmes, in "The Adventure of the Greek Interpreter"
"There are many men in London, you know, who, some from shyness, some from misanthropy, have no wish for the company of their fellows. Yet they are not averse to comfortable chairs and the latest periodicals. It is for the convenience of these that the Diogenes Club was started, and it now contains the most unsociable and unclubable men in town. No member is permitted to take the least notice of any other one. Save in the Stranger's Room, no talking is, under any circumstances, allowed, and three offences, if brought to the notice of the committee, render the talker liable to expulsion. My brother was one of the founders, and I have myself found it a very soothing atmosphere."
Sherlock Holmes, in "The Adventure of the Greek Interpreter"
Mr. Melas, however, still lived, and in less than an hour, with the aid of ammonia and brandy I had the satisfaction of seeing him open his eyes, and of knowing that my hand had drawn him back from that dark valley in which all paths meet.
Watson, in "The Adventure of the Greek Interpreter"
"There is nothing in which deduction is so necessary as in religion," said he, leaning with his back against the shutters. "It can be built up as an exact science by the reasoner. Our highest assurance of the goodness of Providence seems to me to rest in the flowers. All other things, our powers, our desires, our food, are all really necessary for our existence in the first instance. But this rose is an extra. Its smell and its color are an embellishment of life, not a condition of it. It is only goodness which gives extras, and so I say again that we have much to hope from the flowers."
Sherlock Holmes, in "The Adventure of the Naval Treaty"
"You suspect some one?"
"I suspect myself."
"What!"
"Of coming to conclusions too rapidly."
Annie Harrison and Sherlock Holmes, in "The Adventure of the Naval Treaty"
"Look at those big, isolated clumps of building rising up above the slates, like brick islands in a lead-colored sea."
"The board-schools."
"Light-houses, my boy! Beacons of the future! Capsules with hundreds of bright little seeds in each, out of which will spring the wise, better England of the future."
Sherlock Holmes and Watson, in "The Adventure of the Naval Treaty"
Standing on the run between us, with his slight, tall figure, his sharp features, thoughtful face, and curling hair prematurely tinged with gray, he seemed to represent that not too common type, a nobleman who is in truth noble.
The description of Lord Holdhurst, in "The Adventure of the Naval Treaty"
It is with a heavy heart that I take up my pen to write these the last words in which I shall ever record the singular gifts by which my friend Mr. Sherlock Holmes was distinguished.
Opening line of "The Final Problem"
"You have probably never heard of Professor Moriarty?" said he.
"Never."
"Aye, there's the genius and the wonder of the thing!" he cried. "The man pervades London, and no one has heard of him. That's what puts him on a pinnacle in the records of crime."
Sherlock Holmes and Watson, in "The Final Problem"
"As you are aware, Watson, there is no one who knows the higher criminal world of London so well as I do. For years past I have continually been conscious of some power behind the malefactor, some deep organizing power which forever stands in the way of the law, and throws its shield over the wrong-doer. Again and again in cases of the most varying sorts -- forgery cases, robberies, murders -- I have felt the presence of this force, and I have deduced its action in many of those undiscovered crimes in which I have not been personally consulted. For years I have endeavored to break through the veil which shrouded it, and at last the time came when I seized my thread and followed it, until it led me, after a thousand cunning windings, to ex-Professor Moriarty of mathematical celebrity."
Sherlock Holmes, in "The Final Problem"
"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. But his agents are numerous and splendidly organized. Is there a crime to be done, a paper to be abstracted, we will say, a house to be rifled, a man to be removed -- the word is passed to the Professor, the matter is organized and carried out. The agent may be caught. In that case money is found for his bail or his defence. But the central power which uses the agent is never caught -- never so much as suspected."
Sherlock Holmes, in "The Final Problem"
"'You crossed my path on the 4th of January,' said he. 'On the 23d you incommoded me; by the middle of February I was seriously inconvenienced by you; at the end of March I was absolutely hampered in my plans; and now, at the close of April, I find myself placed in such a position through your continual persecution that I am in positive danger of losing my liberty. The situation is becoming an impossible one.'"
Professor Moriarty, speaking to Sherlock Holmes in "The Final Problem"
"'Danger is part of my trade,' I remarked."
"'That is not danger,' said he. 'It is inevitable destruction. You stand in the way not merely of an individual, but of a mighty organization, the full extent of which you, with all your cleverness, have been unable to realize. You must stand clear, Mr. Holmes, or be trodden under foot.'"
Sherlock Holmes and Professor Moriarty, in "The Final Problem"
"Now I have come round to you, and on my way I was attacked by a rough with a bludgeon. I knocked him down, and the police have him in custody; but I can tell you with the most absolute confidence that no possible connection will ever be traced between the gentleman upon whose front teeth I have barked my knuckles and the retiring mathematical coach, who is, I dare say, working out problems upon a black-board ten miles away."
Sherlock Holmes, in "The Final Problem"
"I think that I may go so far as to say, Watson, that I have not lived wholly in vain," he remarked. "If my record were closed to-night I could still survey it with equanimity. The air of London is the sweeter for my presence. In over a thousand cases I am not aware that I have ever used my powers upon the wrong side. Of late I have been tempted to look into the problems furnished by nature rather than those more superficial ones for which our artificial state of society is responsible."
Sherlock Holmes, in "The Final Problem"
"I am bound to say that in all the accounts which you have been so good as to give of my own small achievements you have habitually underrated your own abilities. It may be that you are not yourself luminous, but you are a conductor of light. Some people without possessing genius have a remarkable power of stimulating it."
Sherlock Holmes, to Watson, in "The Hound of the Baskervilles"
"Now is the dramatic moment of fate, Watson, when you hear a step upon the stair which is walking into your life, and you know not whether for good or ill. What does Dr. James Mortimer, the man of science, ask of Sherlock Holmes, the specialist in crime? Come in!"
