My Sister's Grave by Robert Dugoni

It's been twenty years since Seattle police detective Tracy Crosswhite's younger sister, Sarah, disappeared. Edmund House was convicted of the crime and sits in prison, even though Sarah's body was never found. Tracey has a lot of doubts about House's guilt, even though he served time before Sarah went missing. She has also spent a lot of time going over the documents from House's trial. Then Sarah's remains are discovered and Tracy figures this is the perfect time to try and find out who killed her--except that there are those who would like the case to stay closed. My Sister's Grave is the first book in Dugoni's Tracy Crosswhite series. It's been 15 years since I've read a book by Dugoni (Damage Control) and after reading this one, I wonder why it's been so long.
