“Be a MAN in the City Watch! The City Watch needs MEN!”. But what it s got includes Carrot (technically a dwarf), Cuddy (really a dwarf), Detritus (a troll), Angua (a woman, most of the time) and Nobby Nobbs (species unknown). And they need all the help they can get. Because there s evil in the air, murder afoot and something nasty in the streets. It d help if it could be sorted by noon, because that s when Captain Vimes is retiring. But since this is Ankh-Morpork, noon promises to be not just high, but stinking.
