Thud! is Terry Pratchett's 34th Discworld novel, released in the United States of America on September 13, 2005, the United Kingdom on 1 October 2005. Thud! was released in the U.S. three weeks before it was released in Pratchett's native UK, to coincide with a United States signing tour. It was nominated for the Locus Award for Best Fantasy Novel in 2006. In 2010 Thud! won the Discworld Cup finals.

Plot

As the book opens, a dwarf demagogue, Grag Hamcrusher, is apparently murdered. Ethnic tensions between Ankh-Morpork's troll and dwarf communities mount in the build-up to the anniversary of the Battle Of Koom Valley, an ancient battle where trolls and dwarves seemingly ambushed each other. Lord Vetinari convinces Commander Vimes to interview a vampire applicant to the Ankh-Morpork City Watch. The new recruit, Lance-Constable Salacia "Sally" von Humpeding, along with Sergeant Angua and Captain Carrot, is attached to the investigation surrounding Hamcrusher's death.

Meanwhile, Corporal Nobbs and Sergeant Colon begin an investigation into the theft of the fifty-foot painting, The Battle of Koom Valley by the insane artist Methodia Rascal, from a city art gallery. Most of the populace believe the painting holds clues to a treasure hidden in Koom Valley. Nobbs has a new girlfriend, exotic dancer Tawneee; Nobby first caught her eye when slipping an IOU into her garter. Other subplots involve the tension between vampires and werewolves (new recruit Lance-Constable von Humpeding and Sergeant Angua), and the presence of Vetinari's auditor, A.E. Pessimal, in the Watch House.

The fictional universe of the Discworld novels by Terry Pratchett features a number of invented games, some of which have gone on to spawn real-world variants.

Stealth Chess

Stealth Chess is a chess variant, played in the Ankh-Morpork Assassins' Guild, according to The Discworld Companion.

It is similar to normal chess, with the exception of an extra piece and the widening of the board by two specially-colored fields (red and white are described, as opposed to the normal black and white) on either side, known as the Slurks. The extra piece is the Assassin (appearing on either side of the Rooks in the beginning of the game), the only piece to be able to move in the Slurk.

The Assassin moves one square in any direction, and two to capture; however, on exiting the Slurks, the assassin may make as many moves as it has taken within the Slurks and, optionally, a capture move.

An example may clarify: If an Assassin enters the Slurks and takes five moves within them (in any direction, including back and forth), it may then appear in any square that is five moves from its original entry point into the Slurk. It is then still able to make a one-square move to capture. If an Assassin were to make fifteen moves (the minimum necessary to go from one corner of the normal board to the opposite corner), it could reappear anywhere on the board. The mechanism of moving the assassin up and down the Slurks is used in order to a) use up a move by the player and b) to keep count of how many spaces the assassin has moved.

Thud is Kevin Gilbert's debut album as a solo artist, and his last release before his accidental death in 1996.
