Imagining the figure of the fictional detective as an archetype in the study of modern culture, the author argues that contemporary detective fiction can help us better comprehend fundamental shifts of the Digital Age in communication, family, entertainment, society, even the way we think as individuals. The nature of the detective story itself models how we build and share knowledge. Drawing on concepts from literature and media studies, the author reveals clues about modern phenomena like conspiracy theory, groupthink and the nature of our digital identities."
