Information about the author.
Forensic psychologist Paul Britton asks himself four questions when he is faced with a crime scene: what happened; who is the victim; how was it done, and why? Only when he has the answers to these questions can he address the fifth: who is responsible?
An intensely private and unassuming man, Britton has an almost mythic status in the field of crime deduction because of his ability to ‘walk through the minds’ of those who stalk, abduct, torture, rape and kill other human beings. What he searches for at the scene of a crime are not fingerprints, fibres or blood stains—he looks for the ‘mind trace’ left behind by those responsible; the psychological characteristics that can help the police to identify and understand the nature of the perpetrator.
