Quote from : The Letters of Dorothy L. Sayers. Vol. 1, 1899-1936: The Making of a Detective Novelist Book

[N]othing about a book is so unmistakable and so irreplaceable as the stamp of the cultured mind. I don't care what the story is about or what may be the momentary craze for books that appear to have been hammered out by the village blacksmith in a state of intoxication; the minute you get the easy touch of the real craftsman with centuries of civilisation behind him, you get literature.
