I recently read a book called "Spirit Seeker" which is by a great awarding winning author Joan Lowery Nixon. I have read many of her book. "Spirit Seeker" was one of her books I really liked. She always it so you really don't know who the murder is until the very end. I always have my ideas on who the murder is, but I am never totally sure. She makes all the main characters look somewhat guilty. In "Spirit Seeker" the main characters friend is accused of killing both of his parents in a violent stabbing. All of the evidence points to him doing it, but the main character no matter what still thinks he isn't guilty. You will have to read the book to find out who ends up being the killer.
