What are some memorable final lines from novels that you like?
Here's one example of mine, from Raymond Chandler's most ambitious novel, "The Long Goodbye", that I think perfectly encapsulate the world-weary, cynical, and yet regretful tone of that story.
"He turned and walked across the floor and out. I watched the door close. I listened to his steps going away down the imitation marble corridor. After a while they got faint, then they got silent. I kept on listening anyway. What for? Did I want him to stop suddenly and turn and come back and talk me out of the way I felt? Well, he didn’t. That was the last I saw of him.
I never saw any of them again—except the cops. No way has yet been invented to say goodbye to them."
