The Wiley Series in the Psychology of Crime, Policing and Law publishes concise and integrative reviews on important emerging areas of contemporary research. The purpose of the series is not merely to present research findings in a clear and readable form but also to bring out their implications for both practice and policy. In this way, it is hoped the series will not only be useful to psychologists but also to all those concerned with crime detection and prevention, policing and the judicial process. This innovative collection of chapters bridges what used to be a chasm between, on the one side, investigative interviewing (e.g. Bull, Valentine & Williamson, 2009) and, on the other side, forensic linguistics (e.g. Gibbons & Turrell, 2008). A major bridge across this chasm was made by one of this volume’s editors (Tim Grant – a forensic linguist) some ten years ago when he was a Lecturer at Leicester University, when he successfully suggested to me (in my role as Director of Postgraduate Programmes in Forensic Psychology) that we make available to our students a new module/course in forensic linguistics. From this arose a greater appreciation that knowledge on the topic of the present volume (i.e. communication in investigative and legal contexts) is to be enhanced by both a psychological and a linguistic perspective. Encapsulating such diverse knowledge in the one location could present a challenge, but the editors have succeeded in achieving this. The four editors are not only themselves very active researchers but each also is, and has been, directly involved in disseminating the valuable findings of relevant research in the form of workshops, seminars and the like. Their major contributions to and effective participation in relevant international conferences and meetings has allowed the editors to recruit as chapter authors a wide array of leading authors at various stages of their careers
