My name is Sherlock Holmes. It is my business to know what other people don’t know.
You have a grand gift for silence, Watson. It makes you quite invaluable as a companion.
Life is infinitely stranger than anything which the mind of man could invent. We would not dare to conceive the things which are really mere commonplaces of existence. If we could fly out of that window hand in hand, hover over this great city, gently remove the roofs, and and peep in at the queer things which are going on, the strange coincidences, the plannings, the cross-purposes, the wonderful chains of events, working through generations, and leading to the most outre results, it would make all fiction with its conventionalities and foreseen conclusions most stale and unprofitable.
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.
I am an omnivorous reader with a strangely retentive memory for trifles.
When one tries to rise above Nature one is liable to fall below it.
We must look for consistency. Where there is a want of it we must suspect deception.
In my profession all sorts of odd knowledge comes useful.
The giant rat of Sumatra, a story for which the world is not yet prepared.
I am not the law, but I represent justice so far as my feeble powers go.
When you have eliminated all which is impossible, then whatever remains, however improbable, must be the truth.
A complex mind. All great criminals have that.
Good old Watson! You are the one fixed point in a changing age.
To let the brain work without sufficient material is like racing an engine. It racks itself to pieces.
Everything in this world is relative, my dear Watson.
Education never ends Watson. It is a series of lessons with the greatest for the last.
There is but one step from the grotesque to the horrible.
Mediocrity knows nothing higher than itself; but talent instantly recognizes genius.
It is a capital mistake to theorise in advance of the facts.
Come, Watson, come! The game is afoot. Not a word! Into your clothes and come!
Let us hear the suspicions. I will look after the proofs.
It is impossible as I state it, and therefore I must in some respect have stated it wrong.
One should always look for a possible alternative, and provide against it. It is the first rule of criminal investigation.
What one man can invent another can discover.
There is no prospect of danger, or I should not dream of stirring out without you.
There is nothing more stimulating than a case where everything goes against you.
I had little doubt that I had come to the end of my career when I perceived the somewhat sinister figure of the late Professor Moriarty standing upon the narrow pathway which led to safety.
Out of my last 53 cases 49 have been given full credit to the police and the rest to me.
If I were assured of your eventual destruction I would, in the interests of the public, cheerfully accept my own.
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.
Results without causes are much more impressive.
Any truth is better than indefinite doubt.
Nothing clears up a case so much as stating it to another person.
Data! Data! Data! I can’t make bricks without clay.
Violence does, in truth, recoil upon the violent, and the schemer falls into the pit which he digs for another.
It is, of course, a trifle, but there is nothing so important as trifles.
You know my method. It is founded upon the observation of trifles.
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.
Life is infinitely stranger than anything which the mind of man could invent.
It is quite a three pipe problem, and I beg that you won’t speak to me for fifty minutes.
It is a capital mistake to theorize before you have all the evidence. It biases the judgment.
I never guess. It is a shocking habit — destructive to the logical faculty.
