Rapists. Paedophiles. Psychopaths. Their crimes are the most horrific of any criminal and the devastation wrought on the victims and their families is incalculable. Their crimes are often highly organised, systematic and secretive, making their capture a challenge that is never an easy one. In this extraordinary book David Bright takes the reader on a journey into the world of the monsters that plague us. It is an uncompromising, sometimes uncomfortable read, yet vital if we are to understand and combat these demons. His ground-breaking work alerted the public to the existence of organised paedophilia - a menace that had previously either been hushed up, ignored or simply not fully understood. David tells his story with compassion and modesty, revealing the fascinating techniques and methods used to capture the most dangerous men in Britain.
