Malicious Intent by Kathryn Fox
Dr Anya Crichton, a pathologist and forensic physician, finds that work is sparse for the only female freelancer in the field. Between paying child support, a mortgage and struggling to get her business off the ground, Anya can't yet afford to fight her ex-husband for custody of their three-year-old son, Ben.
When Anya is asked to look into the seemingly innocent suicide of a teenager, Anya notices similarities between the girl's death and several other cases she is working on with her friend and colleague, Detective Sergeant Kate Farrer. All the victims went missing for a period of time, only to be found dead of apparent suicide in most unusual circumstances.
As Anya delves deeper, the pathological findings point to the frightening possibility that the deaths are not only linked, but part of a sinister plot. Nothing can prepare her for the terrifying truth...
