Dr. Kate Hanson Series

When, a year after she went missing, the body of 19-year-old student Elizabeth Williams is discovered in a field near her college, Dr Kate Hanson and her colleagues are faced with a seemingly impossible challenge. With little in the way of forensic evidence, Kate realises that if she is to have any chance of discovering who killed Elizabeth, she must find out what motivated the killer, the reason behind the murder, the why.

When a body is discovered locked inside a church crypt, its throat torn out, the victim is quickly identified as 20-year-old Matthew Flynn, son of one of the city's leading entrepreneurs, who disappeared a year earlier. For forensic psychologist Kate Hanson, the evidence reveals careful planning but also loss of control. It makes no sense. Nor can she and her team agree as to motive. Is it drugs? Money? Sex? The only thing that's clear is that Matthew Flynn had been keeping secrets from his family and friends. Then Kate discovers that another young man is missing. And the case takes a disturbing new twist....

For the past 10 years, David Lockman has been serving a life sentence for the murder of Della Harrington. Now an appeal judge has decreed the forensic evidence unsatisfactory and the original verdict unsafe. Tasked with reexamining the case, forensic psychologist Kate Hanson and her colleagues unearth serious flaws in the original police investigation. But if Lockman didn't kill Della Harrington, who did? As they question those involved, it becomes clear that not everyone is telling the whole truth. But have the detectives been working from the wrong assumption from the outset?
