Thud   by Terry Pratchett

The story itself is a fairly complicated detective story, with lots of dialogue and interplay between the various actors, making it scan almost like an Ian Rankin novel. A painting goes missing and some dwarfs are killed in a mine in which, it transpires, a troll happened to be lurking. The ensuing investigation is constantly side-lined by racial prejudices and tensions, and the hero of the book is a human policeman who refuses to take sides and battles to maintain a balanced inquiry. Parallels with issues in the real world are obvious, but thankfully they are never elucidated and the book manages to progress with a happy bounce in its stride.

The only problem that I had was that there are a lot of characters, and keeping track of who is _what_ creates more confusion on an already complicated plot.

The book is most notable, however, for its exquisite balance of outlandish fun and deep philosophical depth. Unfortunately both of these come together in a slightly weak and distinctly improbable climax.
