What are the current and future challenges in criminal investigation carried out by the police in the UK? How has the role of the detective changed over time and is there a real journey towards professionalism?

Written by an author with extensive practical and training experience, this book provides a comprehensive overview and critical analysis of the development and practice of criminal investigation. It examines decision-making within criminal investigations, from volume crime through to major and serious crime investigations and links investigative influences on policing with the evidence-based agenda. The book:

* discusses the move from the art and craft of detective work to a new science-based professionalism;

* contextualises the current position of investigation within the context of government austerity measures and the College of Policing and Government agendas;

* critically examines models of investigation such as the Core Investigative Doctrine and the Murder Investigation Manual;

* explores the legal framework for modern critical investigations and the role of the IPCC.

Part of Key themes in policing, a textbook series of evidence-based policing books for use within Higher Education curriculums and in practice, this book is suitable for policing and criminal justice programmes at undergraduate and postgraduate level.
