What is the author's style in Death Masks by Jim Butcher?

The novel's structure is linear and straightforward, moving from its point of beginning (the confrontation in the television studio) through to its climax/ending (the confrontation on the train) and its denouement, or resolution (the tying up of loose ends) in clear, cause-and-effect, action-reaction fashion. There are occasional and necessary narrative diversions into exposition or back story in which Harry explains events and circumstances in the past that have contributed to the present situation, but for the most part these are brief and don't interrupt the book's overall narrative flow. All that said, it's important to remember, when considering its structure, that the book is part of the mystery-thriller genre. With that in mind, it's possible to see how elements of the book's structure have been designed and shaped to realize that intention.
