I followed the video but did not find one in the church or mansion locations.Sorry for replied before. It's a difficult question I think to answer because of many possibilities. I found 2 old book at this update (one is in church, second in store) but in walkthrough video, they have 3 books. Where is the next one? Looked at all mansion, as it mentioned above (2 or 3 messages above).
Thanks for answers.
