Do you have what it takes to join AC-12?

Superintendent Ted Hastings wants one thing, and one thing only: to catch bent coppers. And he needs your help on a series of brand-new operations.

In Line of Duty Case Files: The Official Puzzle Book, readers step into the shoes of an AC-12 investigator. This fully authorized book combines gripping, entirely original scenarios with mind-bending puzzles that test logic, observation, and nerve.

Grab your pen, open the case file, and start the investigation.

Lydia Ramah, Commissioning Editor at Pan Macmillan, said:

Line of Duty is one of my favourite shows of all time. The excitement of throwing a watch party for the Series 6 finale, tuning in alongside over 12 million of us across the country was completely unmatched. With filming now underway, the buzz around the show’s return is already building and will only continue to grow over the coming months. Dr Gareth Moore has crafted an exceptional collection of brand-new cases and brain-teasers that capture the tension, wit and drama of the show. Line of Duty Case Files will be the ultimate Christmas present for every Line of Duty fan this year.’
