–Terry Pratchett - Guards! Guards! - c.1989, 1990
Discworld series #8 / The City Watch series #1
This is the book. The one that really made me love the Discworld ‘verse.
In this we first meet Sam Vimes and Ankh-Morpork’s Night Watch, and it really is some of the best of Pratchett’s writing. Blending social commentary with humour and insight. It is wonderful.
Sam Vimes is a down and out drunk. All the members of the Night Watch are down and out, the greatest mistake one of their number can make is running to fast and actually catching a criminal! But change is afoot. A new dwarf has come to the Ankh-Morpork to join the Watch, and he has read The Book. He knows the laws and isn’t afraid to arrest people.
And then there is that trouble incident with the dragon…
