What is the main conflict in The Great Fire by Shirley Hazzard?

The Great Fire is a story of men and women affected by war and the ways in which they work to fit back into society in war's aftermath. The influence of war is one that Aldred must overcome if he is to heal. Helen and Benedict Driscoll play pivotal roles in demonstrating to Aldred what is possible should he open himself to the capacity for love. Benedict's ill health has not made the boy bitter or cynical, and Helen's loving care of her sibling represents the emotional support that has been absent in Aldred's own life.
