This was the first time I had been left on my own, in a cell, in a maximum-security prison, with a man convicted of serious sexual offences. It would be far from my last. I have spent the 25 years since that day in the mid-90s, when I was just 22 years old and in possession of a shiny new psychology degree, assessing, treating and researching men who commit sexual offences, including sexual murder.
