The book is about a nurse who took care of a man who was in an accident. Trying to find his identity she went through his belongings and found notes he was taking on how to destroy the Catholic Church from within by entering the priesthood. How he recruted other man. Very good book...you see the fruits of that...not good..in the past few years. The term the “smoke has entered the church” is very clear on what that means. You should read it.
