Guards! Guards! (by Terry Pratchett)

A few years ago I thought I would (gradually) re-read Terry Pratchett’s lengthy Discworld series, but I stopped after the seventh. This is possibly because I looked at the eighth - ‘Guards! Guards!’ - and had a vague memory of not much enjoying it.

We acquired this book back in 1996 and I’m sure I read it soon afterwards, but it’s possible that I have not re-read it at all - and my memories of books read over twenty years ago are often wrong. Sometimes, too, my tastes change over the years...
