What is the author's style in Shadowlands by William Nicholson?

Within each act in Shadowlands, Nicholson has numerous small scenes with clever staging that underline the play's themes and the characters. It is the staging that often defines the transitions between these scenes. The stage directions call for the stage to be divided in two by a translucent screen. The screen defines an inner area and an outer area. Only certain kinds of scenes take place in the inner area: the scenes in the Oxford dining hall; Lewis' study and home, except for one towards the end of Act I when Joy goes into another room during the Christmas party and reads a letter from her husband who wants a divorce; Joy's home in Oxford; the Registry office; and Joy's hospital room. Others take place in the outer area in front of the screen: Lewis' monologues; scenes on the street where characters are walking; the hotel tea room; certain scenes in Lewis' house, especially those in which the outside world is intruding on Lewis; the corridor outside of Joy's hospital room; the scene in Greece. The scenes in front of the screen generally signify the outside world, while those inside are more personal and deep. Changes in lighting also define the passage of time and the change of scene.
