What concept about "the hero" does the novel explore?

The novel emphasizes that heroism is not limited to grand acts of bravery or monumental successes but can arise from the mundane actions and choices of individuals in their everyday lives. Characters such as Dunstan Ramsay exemplify this idea as they navigate personal struggles, contribute to the welfare of others, and display significant moral courage and integrity in ordinary circumstances.
