What is the author's style in Pudd'nhead Wilson by Mark Twain?

The point of view of this novel is third person omniscient. The narrating character shifts from time to time, from Tom, to Roxana, to Wilson. This point of view allows the reader to see the events through the eyes of the narrating characters and to also see their emotion and their thoughts. This novel's point of view is unique, however, in that it also contains the authorial voice. In this novel, although the narration is seen through the eyes of the characters, there are times in which the narration pulls back and a new, unidentified voice speaks directly to the reader. This voice belongs to the author, giving the reader information to understand the setting and to follow the movement of the plot.
