This is number 7 in the DS Katie Maquire series, that combines crime and verges a bit into horror in some parts. The torture of both humans and animals in this one was almost enough to make me stop reading. I also was a bit disappointed by Katie's treatment of her boyfriend John, I found that all a bit out of character.
So although the story seemed to be based on real life criminal behavior it grossed me out a bit too much this time. 3/5
