The book is written from the perspective of a participant observer. It is not strictly an autobiography or a history, although it has elements of both, as it would fail without them. It is intended for both the general reader and criminal justice professionals. My intention is that the book is educational, showing the prison system over three decades in the context of social, political and organisational change, in particular the impact of the decline of deference, the growth of public managerialism and the rise of political correctness. The trenchant opinions expressed are based on intellectual rumination, observation of human behaviour, and personal and professional experience. I have deliberately chosen a thematic approach for the book so that explanation and information work in tandem, giving a unique insight into the modern prison service and the workings of the public sector.
