Life is full of whimsical happenings, Watson.

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

Evil indeed is the man who has not one woman to mourn him.

I say, Doctor, there may be some little danger, so kindly put your army revolver in your pocket.

My dear fellow, 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.

There will probably be some small unpleasantness. Do not join in it.

Let the whole incident be a sealed book, and do not allow it to affect your life.

The only drawback is that there is no law, I fear, that can touch the scoundrel.

You have really done very well indeed. It is true that you have missed everything of importance, but you have hit upon the method, and you have a quick eye for colour.

My dear doctor, this is a time for observation, not for talk. We are spies in an enemy’s country.

It has long been an axiom of mine that the little things are infinitely the most important.

It saved me from ennui. Alas!

If they fire, Watson, have no compunction about shooting them down.

He is, in my judgment, the fourth smartest man in London, and for daring I am not sure that he has not a claim to be third.

My life is spent in one long effort to escape from the commonplaces of existence.

As a rule, the more bizarre a thing is the less mysterious it proves to be.

From what I have seen of the lady, she seems, indeed, to be on a very different level to your Majesty.

Tragic, but ambiguous.

You are the stormy petrel of crime, Watson.

The sofa is very much superior to the usual country hotel abomination.

That is entirely a question of barometric pressure.

What becomes, then, of these nocturnal whistles?

He has one positive virtue. He is as brave as a bulldog and as tenacious as a lobster if he gets his claws upon anyone.

He is not a bad fellow, though an absolute imbecile in his profession.

Very sorry to knock you up, Watson, but it's the common lot this morning.

I can never bring you to understand the importance of sleeves.
