Screwtape Letters (Letter 31)

This book still just really confuses me and I do not enjoy reading it at all.  I feel like I get lost from the very first sentence that I read and never can truly get back into the book.  In this letter Wormwood has lost his patient to the enemy.  I am not quite sure if this lose was due to the fact that the patient died, or if he just recognized that Wormwood was working for Satan and turned away from him, does anyone know which scenario is true? I would assume that the patient died, because I feel like it is hard to live a life where you can recognize Satan completely and knowingly refuse him.  There are too many temptations in our everyday world for us to simply say no.  

The whole rest of the letter was very confusing and I have no idea what Screwtape was trying to tell Wormwood.  If anyone can clarify this for me that would be wonderful.  I am really frustrated, because I thought that the farther we read into the book the more I would understand, but I still seem to find myself very lost.  Please, I need your HELP!!! Thank you!
