What is the author's perspective in the book, Jane?

With the exception of Jane's journal and diary, the rest of the book is told from Nelson's perspective. She will occasionally insert passages from other sources, including "The Michigan Murders" or from Edgar Allen Poe, but it is Nelson who is reacting to these bits of information as a means of trying to grasp a better understanding of the case. Nelson is in a dreamlike state of mind for the most part, as she is trying to reach back into her memories and also user her imagination to work through the task at hand. This allows the reader to better appreciate the difficulty of the task, and this mode of narration also has more emotional resonance, since a regular narrative would be similar to "The Michigan Murders," focusing more on the objective facts of the case rather than the emotional truths that Nelson is trying to reach through her variation in form.
