Rule Horror: 50 Years Ago

I have always liked reading suspense and horror novels. The writing of this novel is very good and makes people want to keep reading. There are many twists and turns in the back, and the answers to the hidden foreshadowings are also revealed. But I really want to say that there are more than a dozen rules every time. For people like us who can't remember it well, it's not easy to gameover in it, haha

This is a suspenseful and horror-themed novel. The author wrote it carefully and it is beautiful.
