Feet of Clay

There's a werewolf with the pre-lunar tension in Ankh-Morpork. And a dwarf with attitude and a golem who's begun to think for itself. But for Commander Vimes, Head of Ankh-Morpork City Watch, that's only the start. There's treason in the air. A crime has happened. He's not only got to find out whodunit, but howdunit too.
