What is the author's style in Last Courtesies by Ella Leffland?

Suspense in this short story is created out of fear of others. Vladimir is so eccentric he is hard to understand. His emotions are unstable and some of his actions are unsociable. He is as likely to explode as he is to read poetry or play a piano composition by Bach. So when the story focuses on the unpredictable Vladimir, readers feel a sense of the unknown, which contributes to the suspense.
