The next day, after his shift at school, Tristram notices that he's being followed. He spends some time trying to lose the person tailing him, but eventually gives up and decides to wait for him in a high-class bar nearby.
Not long after Tristram finds an empty table and orders a drink, the man tailing him comes through the door. The man's uniform indicates that he's a Captain of the Population Police.
Captain Loosley insinuates that he's after Tristram's brother Derek, for some reason, and tells Tristram about Derek's affair with Beatrice-Joanna.
Tristram suddenly realizes that Beatrice-Joanna must be pregnant with Derek's child, not his. In his anger, he reveals his wife's pregnancy to Captain Loosley.
Captain Loosley tries to convince Tristram to murder Derek. Tristram suddenly begins to suspect that he's being used, or set up in some way.
Tristram leaves angry and drunk, intent on finding Beatrice-Joanna and having it out with her. Captain Loosley tries once more to convince Tristram to deal with Derek first.
