Commander Vimes has the joyeous task of upholding the law in Ankh Morpork, along with his strange and unsettling band of watchmen. Together they have to stop assassins, trolls, brigands, robbers, thives and nobility from completely destroying everything around. Not an entirely easy job.
The best Pratchett novel around. I just could not put it down. I even bought is as a audiobook to take along in the car. Truly amazing!!
