In the late 1970s, Detective Ian James had quickly risen through the ranks of the London Metropolitan Police. After ten years, he relocated North to Cleveland where he continued in the role of a detective running informants on the Regional Crime Squad and National Crime Squad to infiltrate the underworld. Drugs and gun were on his watch.

Then, a chance meeting with an old friend changed his life forever. Would he like to be part of a team of just four setting up a brand-new unit working in a dark and challenging world? It meant that for the next two decades he would assume a new identity. For the purpose of the role, Ian became a paedophile. The result is that he saved dozens of children from abuse and sent to prison many who were a danger to society.

This is his incredible true story.
