A man who is not born with the novel-writing gift has a troublesome time of it when he tries to build a novel. I know this from experience. He has no clear idea of his story; in fact he has no story. He merely has some people in his mind, and an incident or two, also a locality. He knows these people, he knows the selected locality, and he trusts that he can plunge those people into those incidents with interesting results. So he goes to work.
