Novelists’ careers take different paths, and sometimes don’t look much like careers at all. It’s true that some start publishing between 25 and 35, and write a novel respectably every two or three years until they die, like Kingsley Amis. Others don’t start until they are 60, like Penelope Fitzgerald, or stop abruptly without warning, like Henry Green, or write one novel and no more, like Harper Lee.
