To continue on the P and P theme - why am I compelled to go on reading, even when I know the ending by heart, and how the plot unfolds? This is a vital question for a novelist approaching the end of a rewrite, obviously. With Ms Austen, I think the answer is always the same - the reader's entanglement with her heroine's emotions is such that we would follow her to the ends of the earth. And we are not disappointed by the restraint of the ending, because of all that lies beneath.
Endings are very difficult; they've got to be right, for the book, they've got to satisfy, they mustn't cheat. They must somehow, I think, be there from the beginning, although at the same time they have to be earned by the process of the writing. And quite often, it seems to me, the writer gets to the end before the reader, who wants just a little longer with a character or plot, so that the release from the world of the book might nor jar or disappoint.
