A Little Death

by A.J. Cross

Published 31 January 2017

Dr Kate Hanson and the Unsolved Crime Unit are facing their most challenging cold case yet: the year-old murder of a female student.

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. The badly decomposed remains are offering up few clues, and witnesses are proving either unreliable or reluctant to talk at all.

With little in the way of forensic evidence, Kate realizes 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. To do that, she must look beyond what she and her colleagues are being told by those who knew Elizabeth - and into the twisted psyche of a dangerous murderer: a killer whom Kate suspects is ready to kill again.

Professor Kate Hanson and the Unsolved Crime Unit unearth some shocking findings when they re-examine a 10-year-old murder case.

For the past ten 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 re-examining 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? In following her hunch, Kate makes a professional decision which undermines her colleagues, and threatens her very future with the Unsolved Crime Unit.

Dr Kate Hanson and the Unsolved Crime Unit are baffled as to motive when the body of a young man is discovered.

When a body is discovered locked inside a church crypt, its throat torn out, the victim's identity is quickly established 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 .
