What is the author's style in Wideacre by Philippa Gregory?

The novel is written in third person from Beatrice Lacy MacAndrew's point of view. The perspective is limited with additional details and information being offered through stories and memories. For example, Beatrice tells of a particular field that is not currently being used as being the site of a great battle in which her ancestors won the land that is currently Wideacre. Through this method, historical details are offered, though the story is self-contained in the current happenings with no real need for historical information. Those things that happen outside Beatrice's line of vision are related through an array of methods, typically conversation. Letters from Doctor Rose—the physician treating John MacAndrews for his alcohol addiction—are used to impart knowledge of his condition. That knowledge is necessary for the reader because John's imminent return means that he is a threat to Beatrice's plans.
