Blackstone's Police Investigators' Manual and Workbook 2022 (Blackstone's Police Manuals)

The book itself is a " heavy" read I would say. A lot of content some of which is unnecessary I suppose since it can be phrased in different ways.The promotional code inside the book doesn't work and when contacting oup for support there is no answer. Disappointing and moved to the other books which are smaller and sum things up better, plus works out slightly cheaper
