Have you read Martin's book, Windswept House: A Vatican Novel? Scary as f_ck. Read it around 2000 as a fiction novel. Then after having jumped on the Q train in 2017, I began re- reading it. It freaked me out so badly that not only did I have to stop reading it, I flushed it from my ereader. Have never done that before but too much of the book seemed true to life after having read anon research.
