What is the author's style in Black Lamb and Grey Falcon: A Journey through Yugoslavia by Rebecca West?

The book does not have a clearly delineated structure. Passages describing West's travels—which include delightful nature descriptions, scenes in restaurants and cafes, and visits to churches and monuments—jostle alongside long and colorful accounts of the troubled history of the Balkans. At any point, triggered by some observation of the scene or a conversation, West is likely to digress about one of her many pet topics. Often she sees deep significance in small details, and a particular incident may prompt her to make sweeping generalizations about life.
