What is the author's style in The Life and Adventures of Nicholas Nickleby by David Edgar?

Edgar perfected several forms of theatrical presentation that resemble filmic methods, such as the "zoom lens" effect, scenic cuts, and superimposed scenes. Through a combination of stage arrangement, lighting, and juxtaposition, Nicholas Nickleby simulates film, as when separate episodes are displayed simultaneously, indicating that actions are occurring in separate parts of London at the same time.

Edgar also makes wide use of double entendre "referential irony," a form of dramatic irony in which the audience understands more than the characters do themselves. Words expressed innocently come to take on a secondary importance. Double entendre refers to a second meaning, but in Edgar's juxtapositions, the second context involves a deeper meaning because of its application to that other context, which is enhanced by the interweaving effect of the two story lines.
