Whenever long bloody feud between dwarfs and trolls heats up the cry, “Koom Valley”, springs up just before both sides decide to fight the next one but now it looks like it’s in Ankh-Morpork but not on Sam Vimes watch. Thud! is the 34th installment of Terry Pratchett’s Discworld series and seventh in the “Watch” subseries focusing Sam Vimes pursuing culprits across the Ankh-Morpork and beyond to bring them to justice, no matter the species.
A dwarf demagogue is killed and a troll is the only witness, all of this as the anniversary of the Battle of Koom Valley is approaching with tensions in Ankh-Morpork between dwarfs and trolls reaching a boiling point. After Sam Vimes learns that the murder was supposed to be hidden from him, he leaps to action to solve the murder as well as not sending both species into war. Unfortunately Vimes has to contend with a new vampire member of the Watch, an auditor, and always making it home by 6 to read to Young Sam. And then the case begins to involve mystical elements, really annoying Vimes especially as they travel to Koom Valley in pursuit of justice.
Although the overall plot was well thought out, especially concerning Vimes there were problems. The various secondary arc, the humor, and quality of writing were noticeably not up to Pratchett’s earlier standards and ranged from bad to passable.
Although Thud! isn’t the best of Pratchett’s work nor the best in the Watch series, it is still a good read for any fan.
