The Fifth Elephant: (Discworld)

Series: Discworld

A few days ago Sam Vimes was a copper - an important copper, true - chief of police - but still, at his core, a policeman. But today he is an ambassador - to the mysterious, fat-rich country of Uberwald. Today, Sam Vimes is also a man on the run. There are monsters on his trail. They're fast. They're werewolves - and they're catching up.
