This is the first book about the intermediary scheme, criminal justice’s untold ‘good news story’. Intermediaries are independent communication specialists who assist children and vulnerable adults at police interviews and trials, helping to improve the quality of their evidence and providing access to justice for those who previously had been excluded. Richly illustrated with case examples through intermediaries’ own descriptions of their work, the book also includes feedback from justice system personnel and over 70 judges. This unique book provides a comprehensive explanation of how intermediaries work in practice and gives ‘behind the scenes’ insights into the criminal process. It will be of interest to practitioners and the wider public in England and Wales and encourage consideration of the scheme elsewhere.
