In "The Devil in the White City," Erik Larson explores the intersection of architecture and true crime during the Chicago World's Fair. Within this narrative, he introduces the idea that exceptional individuals, even those who commit heinous acts like murder, often share distinct physical traits. The quote about great murderers having blue eyes serves as a metaphor for their larger-than-life presence and charisma, indicating that evil can sometimes be alluring or captivating.

This juxtaposition raises questions about human nature and the complexities of morality, suggesting that those capable of profound creativity or destruction often possess similar attributes. Larson's work not only delves into the psychology of such figures but also reflects on the broader societal implications of their actions during a transformative time in American history.
