A long time ago when I was writing for the pulps I put into a story a line like “He got out of the car and walked across the sun-drenched sidewalk until the shadow of the awning over the entrance fell across his face like the touch of cool water.” They took it out when they published the story. Their readers didn’t appreciate this sort of thing — just held up the action. I set out to prove them wrong. My theory was that the readers just thought they cared about nothing but the action; that really, although they didn’t know it, the thing they cared about, and that I cared about, was the creation of emotion through dialogue and description.
That the detective story represented something more to Raymond Chandler than a mere commercial product, furnished for popular entertainment purposes, can be judged from the fact that he came to it late in life, with a long and successful business career behind him.
