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. 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 and threatens to abduct them, 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 this groundbreaking book, renowned psychiatrist Michael H. Stone explores the concept and reality of evil from a new perspective. In an in-depth discussion of the personality traits and behaviors that constitute evil across a wide spectrum, Dr. Stone takes a clarifying scientific approach to a topic that for centuries has been inadequately explained by religious doctrines.

Criminologist Christopher Berry-Dee goes behind bars to get the last word from some of the worst criminals in the world. They speak of their violence and shocking deeds in their own words, from within some of the hardest prisons on earth. These interviews have been collated into this disturbing and unflinching analysis of the criminal mind. Here is what happens when you meet the people most of us know only from our nightmares and newspaper headlines. 

Kerry Daynes has worked with some of the most complex and challenging criminals in prisons and secure hospitals as well as the victims of crime. A large part of her day job is spent delving into the psyche of convicted men and women to try to understand what lies behind their actions and how to set them on the path to becoming law-abiding citizens. Welcome to the life of a forensic psychologist. No two days are the same. The people you work with are wildly unpredictable, sometimes frightening and often deeply frustrating. 

Never before has criminal justice rested so heavily on scientific evidence. With ever-more sophisticated and powerful techniques at their disposal, forensic scientists have an unprecedented ability to help solve even the most complex cases. Angela Gallop has been a forensic scientist for over 40 years. After joining the Forensic Science Service, the first crime scene she attended was for a case involving the Yorkshire Ripper.

In his 26 years in the field, Richard Taylor has worked on well over a hundred murder cases, with victims and perpetrators from all walks of life. In this fascinating memoir, Taylor draws on some of the most tragic, horrific and illuminating of these cases - as well as dark secrets from his own family's past - to explore some of the questions he grapples with every day: why do people kill? Does committing a monstrous act make someone a monster? Could any of us, in the wrong circumstances, become a killer?

Professor David Wilson has spent his professional life working with violent men - especially men who have committed murder. Aged 29 he became, at that time, the UK's youngest ever prison governor in charge of a jail, and his career since then has seen him sat across a table with all sorts of killers: sometimes in a tense interview; sometimes sharing a cup of tea (or something a little stronger); sometimes looking them in the eye to tell them that they are psychopaths.

Revisiting Dr. Michael Stone's groundbreaking 22-level Gradations of Evil Scale, a hierarchy of evil behavior first introduced in the book The Anatomy of Evil, Stone and Dr. Gary Brucato, a fellow violence and serious psychopathology expert, here provide even more detail, using dozens of cases to exemplify the categories along the continuum. The New Evil also presents compelling evidence that, since a cultural tipping-point in the 1960s, certain types of violent crime have emerged that in earlier decades never or very rarely occurred.

Inside the minds of the world's most depraved serial killers. Sunday Times best-selling author Christopher Berry-Dee is the man who talks to serial killers. A world-renowned investigative criminologist, he has gained the trust of murderers across the world, entered their high security prisons and discussed in detail their shocking crimes. The killers' pursuit of horror and violence is described through the unique audiotape and videotape interviews which Berry-Dee conducted, deep inside the bowels of some of the world's toughest prisons. 

We know of psychopaths from chilling headlines and stories in the news and movies - from Ted Bundy and John Wayne Gacy, to Hannibal Lecter and Dexter Morgan. As Dr. Kent Kiehl shows, psychopaths can be identified by a checklist of symptoms that includes pathological lying; lack of empathy, guilt, and remorse; grandiose sense of self-worth; manipulation; and failure to accept one’s actions. But why do psychopaths behave the way they do? Is it the result of their environment - how they were raised - or is there a genetic component to their lack of conscience?

From sex-crazed fiends to cold-eyed professional assassins, only those convicted of the most terrible murders are told they will die behind bars. This audiobook tells the stories of those most depraved killers whose crimes outraged society and demanded the harshest penalty available to a British court.

There are many myths about serial killers: that they are all dysfunctional loners; all white males; only motivated by sex; that they all travel and operate across a wide area; cannot stop killing; are all insane, or evil geniuses; and that they all want to get caught. Of course, there are some serial killers who fit into these categories, but the married Green River Killer was not a dysfunctional loner; there are plenty of female and non-Caucasian serial killers, Dr Harold Shipman was certainly not motivated by sex; and many serial killings (such as the Ipswich prostitute murders carried out by Steve Wright) happen within a confined area.

Throughout his time as a murder squad detective, Trevor Marriott has seen firsthand the wanton slayings and butcheries that have been committed by both men and women who have warped, depraved and sadistic minds. In this fascinating and chilling book, he examines the world's most notorious serial killers and the despicable crimes they committed.

Studies in Forensic Psychiatry is the product of extensive research into the psychological motivations for criminal behavior. Bernard Glueck draws his conclusions from a huge wealth of experience with the criminally insane and with the public health care systems. He recognized the need for criminology to be expanded to reflect a deeper understanding of motive and inclination on the part of the criminal, rather than being considered solely in terms of the criminal act itself.
