Terry Pratchett's The fifth elephant

Commander Vimes is sent to wild, wintry and Transylvania-like Uberwald to establish trade links with the King of the Dwarfs but he ends up trying to stop an inter-species war.

On his side, though, is a talking dog, a reformed vampyre and a self-made man.

You can tell he's self-made because the stitches still show.

Vimes may have arrived as Ankh-Morpork's ambassador but he soon finds it's not all golden chocolate balls.

Now he's an escaped prisoner - out in the icy woods, wearing only the gloomy trousers of Uncle Vanya and being chased by a pack of fascist werewolves who don't play by the rules.
