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`re bright. They`re fast. They`re werewolves - and they`re catching up. Sam Vimes is out of time, out of luck and already out of breath.
