What is the author's style in Sharpe's Christmas by Bernard Cornwell?

The point of view of both stories in "Sharpe's Christmas" is third person. This point of view is omniscient and reliable, proven by the fact that the narrator is frequently able to report upon the thoughts and feelings of the characters in addition to the actions and events that occur in any particular scene. This method of writing is useful as it allows the reader to understand the reasons behind the decisions that are made throughout the narrative. Additionally, this provides foreshadowing in the book as the reader is able to predict upcoming events based on the plans that characters consider.
