Eventually the husband and children show up, but without the mother and the husband is acting most suspicious. The characters in this book (particularly the husband's family) are as chilling and creepy as in any good suspense thriller. It's also a fascinating look at the complexity of marriage, the Mormon faith, and the tenacious struggle for Susan's family to find out what happened to her.
Despite the spoilery subtitle, this book is incredibly gripping, and one of the best true crime books I've ever read. I still get the creeps when I look at that book cover photo.
