Arthur Conan Doyle

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?

I had neither kith nor kin in England, and was therefore as free as air -- or as free as an income of eleven shillings and sixpence a day will permit a man to be. Under such circumstances, I naturally gravitated to London, that great cesspool into which all the loungers and idlers of the Empire are irresistibly drained.

A dog reflects the family life. Whoever saw a frisky dog in a gloomy family, or a sad dog in a happy one? Snarling people have snarling dogs, dangerous people have dangerous ones.

You yourself may not be luminous, but you are a conductor of light.

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.

It seems very strange ... that in the course of the world's history so obvious an improvement should never have been adopted. ... The next generation of Britishers would be the better for having had this extra hour of daylight in their childhood.

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!

"I have seen those symptoms before," said Holmes, throwing his cigarette into the fire. "Oscillation upon the pavement always means an affaire de coeur."

The most winning woman I ever knew was hanged for poisoning three little children for their insurance-money, and the most repellent man of my acquaintance is a philanthropist who has spent nearly a quarter of a million upon the London poor.

Still, it is an error to argue in front of your data. You find yourself insensibly twisting them round to fit your theories.

The world is full of obvious things which nobody by any chance ever observes.

I feel that there is reason lurking in you somewhere, so we will patiently grope round for it.

To his eyes all seemed beautiful, but to me a tinge of melancholy lay upon the countryside, which bore so clearly the mark of the waning year, Yellow leaves carpeted the lanes and fluttered down upon us as we passed, The rattle of our wheels died away as we drove through drifts of rotting vegetation--sad gifts, as it seemed to me, for Nature to throw before the carriage of the returning heir of the Baskervilles.

Where there is no imagination there is no horror.

...while the individual man is an insoluble puzzle, in the aggregate he becomes a mathematical certainty.

Clouds of insects danced and buzzed in the golden autumn light, and the air was full of the piping of the song-birds. Long, glinting dragonflies shot across the path, or hung tremulous with gauzy wings and gleaming bodies.

There is nothing like first-hand evidence.

Indeed, I cannot think why the whole bed of the ocean is not one solid mass of oysters, so prolific the creatures seem. Ah, I am wandering! Strange how the brain controls the brain! What was I saying, Watson?

Love has been taken away from the poets, and has been brought within the domain of true science. It may prove to be one of the great cosmic elementary forces. When the atom of hydrogen draws the atom of chlorine towards it to form the perfected molecule of hydrochloric acid, the force which it exerts may be intrinsically similar to that which draws me to you. Attraction and repulsion appear to be the primary forces. This is attraction.

All right, Watson. Don’t look so scared,” he muttered in a very weak voice. “It’s not as bad as it seems.” “Thank God for that!” “I’m a bit of a single-stick expert, as you know. I took most of them on my guard. It was the second man that was too much for me.” “What can I do, Holmes? Of course, it was that damned fellow who set them on.
