This book examines the narratives of series heroines that preceded and followed Nancy Drew, each in relation to their social, historical, and economic environments. Covering heroines including Miss Pickerell, Madge Sterling, and Polly the Powers Model, among others, this book illustrates that the recovery of stolen inheritances during the Great Depression serves different social ends than, for example, fighting Germans on an international stage. This book expands scholarship that tends to focus on Nancy Drew by drawing attention to the stories of some other “lost” heroines of twentieth century U.S. series fiction. Organized by time period, the chapters give insight into the cultural landscape that perpetuated the popularity of these heroines in their respective eras, how these series reflected the experiences of readers across the decades, and their continued impact well into the twenty-first century.
