Having accomplished his mission (according to his understanding with the General’s minions), found a place to live, and settled his other personal affairs, Waterhouse begins hanging around the Ascot Racetrack and the adjacent whorehouse, trying to find some way to make himself useful. Actually he would rather sit in his room all day and work on his new project, which is to design a high-speed Turing machine. But he has a duty to contribute to the war effort. Even if he didn’t, he suspects that when his new roommate gets back from his mission, and finds him sitting indoors all day drawing circuit diagrams, he will thrash Waterhouse to the point where Mrs. McTeague will no longer like his looks.
