I'm still a little stuck on Tandy's disappearance and the main case (the murders of a young couple who seemed to have no enemies) being connected. I'm not sure how useful this review is going to be, since I've already started on Innocent in Death and I finished this book yesterday.
The layers of this case get a little confusing at some point. Who it was doesn't make any sense until Eve digs into the layers of the victims lives. Several more people die before the end of the book and at least one of them is made to look like a suicide.
I think I got a little caught up in Tandy's disapearance by the time the murder case was solved to really be all that into the who's and why's.
