The Blackstone's Police Investigators' Workbook 2008 is the official accompanying study text for the National Investigator's Exam (NIE) which is taken as part of Phase 1 of the Initial Crime Investigators' Development Programme. It contains many practical excercises, case studies and multiple choice questions to help students prepare for the NIE. The Workbook takes the trainee investigator through each of the topics relevant to the examination, namely in the areas of Property Offences, Assaults, Drugs, Firearms & Defences, Sexual Offences, Offences Against Children and Evidence. The book also contains useful cross references to the Manual in the answers sections, so students can check their understanding of the content.

Based on the content of the Investigator's Manual, the book has been completely revised for the 2007/8 syllabus with reference to all recent legislative changes including the new RIPA and updates to PACE, incorporating coverage of Stop, Search and Seizure Powers.
