The Woman Inside is an intriguing mystery book about the death of a rich couple. It follows their maid and the person she lives with, a father named Bill Olsson. I was really confused by the point of him at first. I haven't read this author's other book A Nearly Normal Family, but I liked the writing style and different point of views. This helped me learn the roles of the different characters. Karla is a maid for the Rytters, the rich couple that gets killed, but while working for them she lives with Bill and his daughter Sally to help him pay rent. However there's sinister things going on at the Rytter's house and Sally and Bill get roped in as they try to get money. As far as thrillers go, this didn't feel like anything special. No twists jumped out at me. But it was an entertaining enough read. It's almost 400 pages but felt like a quick read to me.
