The book, by one of my favorite writers, tells the story of a world-weary architect who travels to the heart of Africa to escape his life yet is found there by a journalist. Like all Greene's books, whether set in Africa or Haiti, it's full of sounds, sights and smells.
Classic journalism demands that every story tell the reader who, what, when, where, how and why.
Every writer must be equally specific, no matter what the subject. It might add to our picture of her, both visually and psychologically. Or it might not. If it does, don't leave it out. As a newspaper reporter in Toronto, I once followed the Pope around for a day.
