Dead to Rights

Someone had killed Melly Warren.
Melly herself had let them know when Mike brought her to meet Jack & Jamie. She knew that her killer had most likely been her husband. Seemed like a simple case, right? Domestic violence, arrest the husband, case closed.
Not so much. When Jack and Jamie think they've got the case in the bag, everything gets upended with a twist even Mike didn't see coming.
Just when you think you've got the killer dead to rights, you find out there's a whole lot more going on and the list of dead - and killers - gets a whole lot longer.
