Golding wrote a play?! Wow. I started reading, and couldn't stop: clever, fast moving and funny. Golding expunged all the the tedious misunderstanding and stunted communication characteristic of Shakespeare that turned me against the medium. If all plays were this good, I'd read a lot more of them!
An emperor deals with the problem of his heir, and the legitimate son and the illegitimate son are in a conversation about, not loyalty to the emperor, but about their respective career aspirations (Edmund and Edgar can be put to rest forever, thank goodness!) An inventor struggles to communicate his vision of the future to the Emperor and his son(s) who are, predictably, more caught up in survival due to family infighting, and the persistent concern about Christians (which is, hilarious, characterized by a complete lack knowledge about the Christian belief system they consider to be so offensive.) There is a fantastic clash of competing ideologies - christian, pagan, and reason itself - for both solving problems - everything from how to survive the advancing army, the problem of succession, how to cause a woman to love you, and optimization of naval commutes, to how to live a good life - to interpreting events such as the great clash of fire and smoke that seriously dented the muscle of the invading army. There is also a hilarious rejection of labor saving technology (steam) on the basis that it would render slavery unnecessary - a benevolent Emperor, it seems, worries about employment for all echelons of the society he rules.
