What is the author's style in The Berlin Stories: The Last of Mr. Norris, Goodbye to Berlin by Christopher Isherwood?

The most noteworthy use of language in this pairing of stories is the creation of a certain sense of objectivity, of distance between the observations of the narrator(s) and himself. Events are described in language that contains little or no opinion and/or explanation - things happened as they happened, are shown as they happened, and are to be interpreted and/or understood on their own terms, rather than those of the author/narrator. Literary devices (parallels, metaphors, etc) are used sparingly, and appear more in "Goodbye to Berlin" which has a slightly more poetic sensibility in its writing (for an example of one of the very few instances of metaphoric writing in "...Mr. Norris" see "The Last of Mr. Norris" - Chapter 14).
