What is the author's style in Lady Audley's Secret by Mary Elizabeth Braddon?

The book was first serialized in 1861 in a magazine, and is formatted into three volumes, Volume I, Volume II, and Volume III. The language of Lady Audley's Secret reflects the esoteric and highbrow terminology frequently found in Victorian literature, and Braddon often interjects with authorial narration to help the reader better understand the motives of individual characters, as if she is unable to have her characters relay that information to the reader themselves.
