If the spoiler function doesn't work, I will re-do this.
This post gives my detailed analysis of two of the major issues I had with this book. I've locked most of it in "spoiler" mode. Many of you may consider it unnecessary nit picking, and maybe it is.
I've given page numbers based on the 1987 Berkley paperback edition and tried to add chapter/section numbers as often as I could remember to do so, for those who are reading other editions.
One of the issues I had was with the house itself, the second was Ruth's relationship with Pat. Again, this is very tight analysis, which some readers may not be comfortable with.
