What is the author's style in Paul's Case by Willa Cather?

"Paul's Case" centers on a high school student so taken by the life of wealth and culture that he runs away to New York City on stolen money to live lavishly, if only for a while. When his old middle-class life threatens to reclaim him, Paul commits suicide. The narrator's attitude towards Paul's actions is ironic. The narrator does not endorse Paul's decision to steal in order to live grandly. Nor does the narrator affirm Paul's decision to commit suicide after he realizes that "money was everything."
