Discussions of Coward's achievement in the theatre between 1920 and 1966 have tended to stay with the colourful biography. The more analytical literary approach adopted here places Coward's success in its wider theatrical context, making the connections with the work of other dramatists. He developed his technique according to what worked with theatre audiences. Taking up the well-made play, he brought in a more colloquial dialogue, explored, for instance, the morality and psychology of marriage and free love, and frequently exploited the dramatic possibilities of characters grouped into two camps. The book considers both the 'pleasant' and 'unpleasant' plays (to use the Shavian terms), and the episodic patriotic plays. It Includes Coward's ambivalent approach to the 'theatre of war' in the 20th century. (123)
