This book presents an exploration of how Golden Age detective fiction encounters educational ideas, particularly those forged by the transformative educational policymaking of the interwar period.Charting the educational policy and provision of the era, and referring to works by Agatha Christie, Dorothy L. Sayers, Edmund Crispin and others, the book explores the educational capacity and agency of literary detectives; the learning spaces of the genre; and the kinds of knowledge that are made available to inquirers both inside and outside the text. It is argued that the genre explores a range of contemporaneous propositions on the balance between academic curriculum and practicum, length of school life, and the value of lifelong learning. The book's closing chapter considers the continuing pedagogic value for contemporary classrooms of engaging with the genre as a rich discursive and imaginative space for exploring educational ideas.Framing Golden Age detective fiction as a genre profoundly concerned with learning, this book will be highly relevant reading for academics, postgraduate students, and scholars involved in the fields of English language arts, 20th century literature, and the theories of learning more broadly. Those interested in detective fiction and interdisciplinary literary studies will also find the volume of interest.
