After attempting to illegally crossover into Ul Qoma, Mr Geary is taken by Breach and swiftly deported from Beszel with his wife. Borlú is desperate to know who Mr Geary was planning to meet, but it is out of his hands. Major Syedr leads a rally before swarms of True Citizens - the extreme right nationalist group in Beszel. Borlú thinks that TCs were involved in Mahalia's death, that Syedr is hiding something and knows more about Mahalia's death than he's letting on. Before Borlú can ask him more questions, one of Syedr's men launches a snooker ball at Borlú, knocking him out. Gadlem tells Borlú Mahalia's murder is now with the Ul Qoman Militsya. Borlú doesn't want to give the case up - he needs to go to Ul Qoma to investigate it. Maybe Katrynia is still there? Maybe he can find her? Borlú takes the orientation course, learning to see Ul Qoma and block out Beszel, and he remembers when he first did the course all those years ago with Katrynia. Corwi gives Borlú a code if he runs into trouble, and Borlú tells her to keep watching Syedr. Borlu is taken across a unique border to Ul Qoma, where he is met by SENIOR DETECTIVE DHATT. She makes it clear to him this is now her investigation - Borlú now works for her.
