#20series20days. The Dalziel and Pascoe series
I love these police procedural mysteries with a side of politics. Reginald Hill used these books to discuss issues that interested him. I think some of the books would feel a little dated now, we've moved on from some of these things, but I'm still sorry he died before he finished what had to say about government responses to the resurgence of terrorism. There are 25 books in all - these are a taste.
