Christopher Berry-Dee is back. In Talking With Serial Killers: World's Most Evil, the bestselling author delves deeper still into the gloomy underworld of killers and their crimes. He examines, with shocking detail and clarity, the lives and lies of people who have killed, and shines a light on the motives behind their horrific crimes.

Christopher Berry-Dee gained the trust of some of the most infamous convicted killers, having corresponded with them and even entered their prison lairs to discuss their horrific crimes in detail. In this book, he presents six unforgettable prisoners and allows them to tell their stories.

With unprecedented access to the world's most evil killers, Christopher spent years interviewing imprisoned criminals - including notorious serial killers - he discovered that the lack of remorse these people showed was in many ways even more terrifying than the crimes they had committed.

Because female murderers, and especially serial murderers, are so rare compared with their male counterparts, this new study will surprise as well as shock, particularly in the cases of women like Beverley Allitt, who kill children, and Janie Lou Gibbs, who killed her three sons and a grandson, as well as her husband.

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.
