Chapter 22 was really the height of The City and the City. Dhatt and Yolanda had just been shot in Copula Hall and Borlú was after the shooter. As the murderer fled he “was jogging through the Besź crowds”, while Borlú was in Ul Qoma running down “quieter alleys” (p. 236). As they both started to reach total areas of Besźel and Ul Qoma, respectively, Borlú was running out of time. “He stepped toward space where no one in Ul Qoma could go. I raised the pistol and shot him” (p.237).
Borlú knew he had breached. He looked into Besźel without unseeing and he had also murdered the murderer over the border. Borlú had heard “Breach, Breach” (p 237). He stated that “thought it was a shocked declaration by those who had witnessed the crime”, But he thought wrong. I thought this was weird how Breach arrived so quickly. The way Borlú described how quickly the “unclear figures” and the “grim-featured something” emerged and grabbed him seems like this happened immediately after he had shot the murderer (p. 237-238)
I thought Breach was more of a government figure. Like they would hold court hearings like we have here in the US. Instead, they actually go out, respond, and pick up they people that breach.
