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 citys ramshackle Night Watch is used to this. Its 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 dont fully understand, and theyre about to unleash a campaign of terror on the city. Time for Captain Vimes to sober up.
