As Line of Duty completes its sixth and possibly final series, just how close to reality was it?
As it happens, the end of the run coincides with the publication of Rot at the Core, an in-depth investigation into the life and times of one of Britainâs most spectacularly corrupt police officers, whose career ended in disgrace before his death in a prison cell.
The authors are a former detective superintendent, Graham Satchwell, who investigated corruption in his own force, and Winston Trew, a victim of the bent officer, whose wrongful conviction from nearly 50 years ago was only recently overturned.
