This was a solid whodunit. You move back and forth between two timelines of two different mysteries that converge in the present. The past timeline was used a bit sparingly but still pretty interesting.

Annie is an interesting main character because she is thrust into the mystery and we watch her develop emotional attachments to family that she never knew. The motivations shift and change throughout the story which helps keep you guessing without obvious red herrings. 

One big aspect is that Frances (the deceased) kept files on everyone in town so everyone had motive. I loved that and it seemed underused. We get little bits that tie directly into the mystery, but it would have been great to paint a bigger picture of the town by showing us some of the files that were not relevant to the case.
