From the signals of lying to the profiling of criminals, this guide will demonstrate how understanding the mind helps us better appreciate the justice system.

It is a conundrum that has vexed societies throughout history: how do you deal with those that break the law? If their aim is to evade you, how do identify them? If their aim is to lie, how do you interview them? If they don't see their actions are wrong, how do you help them to successfully reform? Criminal psychology is the discipline which tackles these challenges head on. From the signals which give away we're lying to the psychological profiling of violent offenders, this exhaustive guide, written by the UK's top experts, is the perfect introduction. Also covering policing, and the much debated topic of sexual offenders and their treatment, it will demonstrate how understanding the mind will help us to view modern justice from a more informed perspective.
