What is the author's style in Deviant: The Shocking True Story of Ed Gein, the Original Psycho by Harold Schechter?

Perspective is an important stylistic component to this. The story is written in third person with a somewhat limited omniscient view. The use of the third person perspective is the only option because Ed Gein did not tell his story and the story is non-fiction. No other person could have offered up the details presented by this author, making third person the only viable option. While an omniscient view might have been preferable, the author is again limited by the fact that this story is reported as nonfiction. There are many details that are simply not known. It should be noted that the author has taken some liberties with the story.
