This book is a study of the British casino industry and how it has been shaped by criminality, prohibition, regulation and liberalization since the beginning of the First World War.The reader will gain a detailed knowledge of the history, culture, identity and participants within the British casino industry, which has, to date, escaped the attention of a dedicated historical and criminological investigation. This monograph fills this gap in inquiry while drawing on primary source material that has not been used previously, including, but not confined to, records in the National Archives relating to the Gaming Board of Great Britain and the Metropolitan Police. In addition to archive material, oral histories, newspapers, published journals and books have been utilised and referenced where appropriate.Envisaged to close a gap in historical research, this book will be of interest to historians, criminologists, regulators, students and individuals interested in gambling, society and cultural history.
