In "The Devil in the White City," Erik Larson intertwines the stories of the 1893 World's Fair in Chicago and the infamous serial killer H.H. Holmes. The fair showcased technological wonders and American ingenuity, reflecting a time of transformation in both architecture and society. Among the innovations celebrated was the Kodak camera, a revolutionary invention that democratized photography by requiring no intricate adjustments like lens and shutter settings.

Larson skillfully contrasts the excitement of the fair with the dark, chilling actions of Holmes, who preyed on fairgoers. This dual narrative explores the brilliance of the era alongside the underlying madness, illustrating how the celebration of progress coexisted with hidden horrors. The Kodak camera symbolizes this shift, capturing moments of joy while also linking to the sinister events unfolding simultaneously in the city.
