What is the author's style in The Shadow Box by Michael Cristofer?

Events of the play are presented outside of anyone character's perspective, in the third person. At no time does a character address the audience oroffer any special insight into his or her motivations or actions. Instead, the audience is able to draw conclusions about the characters themselves by observing them in dialogue with various other characters. The dynamic nature of such interactions gives breadth and depth to these individuals and helps the audience to better understand their motivations.For example, Agnes reveals to the interviewer that she has been writing phony letters fromher deceased sister to her mother, Felicity, for two years. In later scenes with her mother, Agnes sayssimply, "If I told you the truth, mama, would you listen?" The audience is already privy to what the truth is without actually hearing Agnes's admissionto her mother.
