The letter begins by brining up the patient's new girlfriend and Screwtape seems really annoyed that the nephew has not included this significant fact in his last letter. In response to his annoyance he sends his nephew a booklet.
Screwtape seems very disgusted by the patient's new girlfriend calling her a "brute" and states "she makes me want to vomit" why does Screwtape feel this way about the girlfriend?
When he talks about her house he speaks of it reeking and that anyone who visits smells horribly after they leave the house. What is the smell suppose to symbolize?
I also thought that it was very interesting that at the end of this letter he turns himself into a centipede...how that happened I am not quite sure though.
Overall this was just a very jumbled and confusing letter.
Hopefully some of you can help me to better understand the deeper meaning!
