This book explores the thought of – and is dedicated to – David Frisby, one of the leading sociologists of the late twentieth and early twenty-first centuries. Presenting original examinations of his unique social theory and underlining his interdisciplinary approach to the critical interpretation of modern metropolitan society and culture, it emphasises Frisby's legacy in highlighting the role of the social researcher as a collector, reader, observer, detective and archivist of the phenomena and ideas that exemplify the modern metropolis as society. With contributions from sociologists, cultural theorists, historians of the city, urban geographers and designers, and architectural historians and theorists, The Detective of Modernity constitutes a wide-ranging engagement with Frisby's profound legacy in social and cultural theory.
