This is the shocking story of a doctor who was addicted to murder: a man who wickedly abused the trust of his patients with horrifying results. He was a pillar of the community: attentive, kind, never too busy to chat. Yet behind this charming facade lay the world's most prolific serial killer, with at least 200 victims. Small, bespectacled Dr Shipman was making house calls - and then committing murder with bloodcurdling expertise and professionalism. He saw himself as playing God. 

Sunday Times best-selling author Christopher Berry-Dee is back with a companion volume that delves even deeper into the savage world of psychopaths and their hideous crimes. This time, however, he combines sections on killers whom he has known, interviewed or corresponded with, with studies of psychopathic serial killers from the past, including Peter Kürten, the 'Düsseldorf Monster'; John Christie, responsible for the killings at 10 Rillington Place; and Neville Heath, a ladykiller in every sense of the word.

They speak of their violence and shocking deeds in their own words, from within some of the hardest prisons on earth.

Here is what happens when you meet the people most of us know only from our nightmares and newspaper headlines. 

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.

As oil-boom money poured into Anchorage, Alaska the city quickly became a prime destination for the seedier elements of society: prostitutes, pimps, con men, and criminals of all breeds looking to cash in. However, something even worse lurked in their midst. To all who knew him, Robert Hansen was a typical hardworking businessman, husband, and father. But hidden beneath the veneer of mild respectability was a monster whose depraved appetites could not be sated. From 1971 to 1983, Hansen was a human predator, stalking women on the edges of Anchorage society.

On 7 August 1985, Nevill and June Bamber, their daughter, Sheila, and her two young sons, Nicholas and Daniel, were discovered shot to death at White House Farm in Essex. The murder weapon was found on Sheila's body; a Bible lay at her side. All the windows and doors of the farmhouse were secure, and the Bambers' son, 24-year-old Jeremy, had alerted police after apparently receiving a phone call from his father, who told him Sheila had 'gone berserk' with the gun. It seemed a straightforward case of murder-suicide, but a dramatic turn of events was to disprove the police's theory. 

At the heart of countless crimes lie the mysteries of the human mind. In this eye-opening book, Dr. Cheryl Paradis draws back the curtain on the fascinating world of forensic psychology, and revisits the most notorious and puzzling cases she has handled in her multifaceted career. Her riveting, sometimes shocking stories reveal the crucial and often surprising role forensic psychology plays in the pursuit of justice - in which the accused may truly believe their own bizarre lies, creating a world that pushes them into committing horrific, violent crimes.

If you've heard any news report on the upsurge in knife crime recently, you'll have heard the words 'county lines'. From the street slang that was once known as 'going country' - it sees powerful drugs gangs supplying outside of the capital through an underworld 'emerging markets enterprise', using children as young as 12 and vulnerable men and women to do their dirty work. Teens whose bereaved relatives assume they led ordinary lives, who tell us they were 'good kids', suddenly end up stabbed to death with no seeming motive.

The principal criminal court of England, historically reserved for the more serious and high-profile trials, Court Number One opened its doors in 1907 after the building of the 'new' Old Bailey. In the decades that followed it witnessed the trials of the most famous and infamous defendants of the twentieth century. It was here that the likes of Madame Fahmy, Lord Haw Haw, John Christie, Ruth Ellis, George Blake (and his unlikely jailbreakers, Michael Randle and Pat Pottle), Jeremy Thorpe and Ian Huntley were defined in history.... 

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. 

Where can a tin of tuna buy you clean clothes? Which British education system struggles with 50 percent illiteracy? Where do teetotal Muslims attend AA meetings? Where is it easier to get 'spice' than paracetamol? Welcome to Her Majesty's Prison Service, a creaking and surreal world that has been left to rot for decades in the shadows of polite society. Like most people, documentary-maker Chris Atkins didn't spend much time thinking about prisons. But after becoming embroiled in a dodgy scheme to fund his latest film, he was sent down for five years.

To his neighbors, Wayne Nance, a furniture mover from Missoula, Montana, appeared to be an affable, considerate, and trustworthy guy. No one knew that Nance was the "Missoula Mauler," a psychopath responsible for a series of sadistic sex slayings that rocked the idyllic town between 1974 and 1986. Nance's only requirement for murder was accessibility - a preacher's wife, a teenage runaway, a female acquaintance, a married couple. Putting on a friendly façade, he could easily gain his victims' trust. Then, one September night, thirty-year-old Nance pushed his luck.

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.

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.
