The fifth elephant

The Fifth Elephant is the latest installment in the Discworld cycle starring dwarfs, diplomacy, intrigue and big lumps of fat . . . Sam Vimes is a man on the run. Yesterday he was a duke, a chief of police and the ambassador to the mysterious, fat-rich country of Uberwald. Now he has nothing but his native wit and the gloomy trousers of Uncle Vanya (don't ask). It's snowing. It's freezing. And if he can't make it through the forest to civilization there's going to be a terrible war. But there are monsters on his trail. They are bright. They are fast, and they are catching up!
