The impulse to perfection cannot exist where the definition of perfection is the arbitrary decision of authority. That which is born in loneliness and from the heart cannot be defended against the judgment of a committee of sycophants. The volatile essences which make literature cannot survive the clichés of a long series of story conferences.

There are people who can write their memoirs with a reasonable amount of honesty, and there are people who simply cannot take themselves seriously enough. I think I might be the first to admit that the sort of reticence which prevents a man from exploiting his own personality is really an inverted sort of egotism.

All men who read escape from something else into what lies behind the printed page; the quality of the dream may be argued, but its release has become a functional necessity.

When in doubt, have a man come through the door with a gun in his hand.

Love interest nearly always weakens a mystery because it introduces a type of suspense that is antagonistic to the detective's struggle to solve the problem. It stacks the cards, and in nine cases out of ten, it eliminates at least two useful suspects. The only effective love interest is that which creates a personal hazard for the detective - but which, at the same time, you instinctively feel to be a mere episode. A really good detective never gets married.

When the plot flags, bring in a man with a gun.

Shake your business up and pour it. I haven't got all day.
