Perfect marriage. Perfect husband. Well, the wife is not perfect, but a prisoner. A prisoner of complete idiocy.
Behind Closed Doors (affiliate link) by B.A. Paris is a highly praised thriller that has nothing thrilling in it. The entire book is just about the wife's life as a prisoner, and how she ended up there. Nothing exciting happens at any point.
Why so few books marketed as (psychological) thrillers really aren't?
SPOILERS!!
BEWARE!!
Behind Closed Doors is not suitable for animal lovers!
The main reason why this book should be burned at the stake is what happens to a small, helpless dog. The only consolation is that at the end the murderer of the dog in question experiences the exact same fate himself. If you can't stand the death/torture/murder of a dog/animal, don't read this book!
The husband threatens the main character that if you don't obey, I'll put your sister in an institution. Well, in this situation, that institution would be the better place for her, so the main character should have just said, please do that!
