An investigative criminologist, Christopher Berry-Dee is a man who talks to serial killers. Their pursuit of horror and violence is described in their own words, transcribed from audio and videotape interviews conducted deep inside some of the toughest prisons in the world. Berry-Dee describes the circumstances of his meetings with some of the world's most evil men and reproduces, verbatim, their very words as they describe their crimes and discuss their remorse - or lack of it. This work offers a penetrating insight into the workings of the criminal mind.
