Michelle Knotek, Killer - Paperback

Michelle and David Knotek lived just outside of Raymond, Washington. Their home was one of the better ones in the area - on the outside at least. Theirs was a large and beautiful farmhouse sitting in its own four acre plot. The idyll was furthered by the large number of well cared for animals that roamed the farmhouse's extensive grounds.
But inside the warm walls life was very different; three people were murdered viciously within that plot; two following months of monstrous torture after which their bodies simply stopped working.
