'Vimes ran a practised eye over the assortment before him. It was the usual Ankh-Morpork mob in times of crisis; half of them were here to complain, a quarter of them were here to watch the other half, and the remainder were here to rob, importune or sell hotdogs to the rest. ' Insurrection is in the air in Ankh-Morpork. The Haves and Have-Nots are about to fall out all over again. Captain Sam Vimes of the city's ramshackle Night Watch is used to this. It's enough to drive a man to drink. Well, to drink more. But this time, something is different - the Have-Nots have found the key to a dormant, lethal weapon that even they don't fully understand, and they're about to unleash a campaign of terror on the city. Time for Captain Vimes to sober up.
