He is killed by Vimes during the fire at the Unmentionables' headquarters. On arriving at the Great Desert he tries to use his phrenological skills to determine Death's character, only to find that Death has no characteristics he can measure. The name Captain Swing has long been associated with civil unrest, being the pseudonym of the (possibly mythical) leader of the Swing Riots. Before the merging of the Watches, the Day Watch dealt with all crimes committed during daylight. The only significant Day Watch member mentioned is its captain, "Mayonnaise" Quirke, who first appears in "Men at Arms". Quirke is nicknamed "Mayonnaise" by the Night Watch as he is rich, thick, oily, and smells faintly of eggs. In "Night Watch" he is revealed to be a little bit older than Vimes. He was originally a Corporal in the Night Watch before kicked out by Sergeant-at-Arms John Keel (actually Vimes). He joined the Day Watch shortly afterwards and presumably rose to the rank of captain at the same time as Vimes did. During the events of "Men at Arms", he is knocked out by Carrot, who tells his men to leave the city; presumably, Quirke left with them. A Klatchian warrior who accompanies the Klatchian envoy Prince Khufurah on a diplomatic journey to Ankh-Morpork in the novel "Jingo". He speaks with a heavy accent and has a penchant for chewing on cloves. Following an attempt on the prince's life by an unknown assassin, he is suspected of killing the Watch's prime suspect, provoking Vimes and other Watch members to pursue him back to Klatch (Particularly after he captures Angua in werewolf form). Apart from belonging to a vicious but honorable warrior clan known as the D'regs, he is later revealed to be the Wali of Klatch, a Klatchian equivalent of a watchman on a par with Vimes (Wali is both a play on the British term "Wally", meaning a simpleton or halfwit and an Arabic word equivalent to "magistrate"). It also turns out his obsessive clove-chewing and broken Morporkian are in fact a disguise meant to delude foreigners into falsely assuming he is nothing but an uncivilized barbarian. Like many privileged foreigners, he was sent to the Assassins' Guild as a child on the assumption that he would get an excellent education. He confounds Vimes by his fond memories of Ankh-Morpork, and even Cut-Me-Own-Throat Dibbler.
