Kerry Daynes, leading forensic psychologist, opens up the case files of some of her most perplexing clients to uncover what lies buried behind some of the most extreme and disturbing behaviour.

For twenty-five years, Kerry has worked on the frontline of violent crime, from working with the police on complex cases and acting as an expert witness in court, to advising the government on how to handle high-risk individuals.

Whether she is dealing with a young murderer who says he has heard voices telling him to kill, a teacher who daubs children in red paint, or an aspiring serial killer who faints at the sight of blood, Kerry's quest is to delve beyond the classic question asked of her profession: 'Are they mad or are they bad?'

In her new book, Kerry provides an unflinching, enlightening and provocative insight into the minds of her clients, shedding light on the root causes of their behaviour and challenging our notions about who, and what, is dangerous.
