Guards! Guards!

Terry Pratchett’s Guards! Guards! begins when a secret society summons a dragon to Ankh-Morpork, expecting the creature to create a crisis that will place their chosen puppet on the throne. The plan escapes their control. Captain Sam Vimes and the depleted City Watch—Sergeant Colon, Corporal Nobbs, and idealistic new recruit Carrot Ironfoundersson—must investigate fires that powerful citizens prefer to explain away. Sybil Ramkin’s knowledge of swamp dragons gives Vimes evidence that the city’s impossible visitor is real and that somebody deliberately called it.

The novel turns the police procedural into a comic argument about civic responsibility. Vimes starts as a drunk who assumes corruption is permanent, but Carrot’s literal belief in law forces the Watch to reconsider what its badge could mean. Pratchett sets heroic fantasy against paperwork, class privilege, mob enthusiasm, and the practical hazards of dragons. Ankh-Morpork is saved neither by noble blood nor prophecy; its defense depends on overlooked public servants learning to act together. That institutional awakening gives the jokes their consequence and establishes the City Watch as a durable center of Discworld.
