Graham meets Ostrog, who says that the rebels have won and that the people are demanding that the Sleeper should rule. Ostrog retains power while Graham becomes his puppet ruler. Graham gets interested in aeroplanes and learns how to fly. He sees from the air that no-one lives in the country or small towns any more, all agriculture being run like industry; and that there are now only four huge cities in Britain, all powered by huge wind-mills. His carefree life ends when Helen Wotton tells him that, for the lower class, the revolution has changed nothing. Graham questions Ostrog who admits that the lower classes are still dominated and exploited, but he defends the system. It emerges that Ostrog only wanted to take power for himself and has used the revolution and Graham to do so.
