The second episode - Rap Sheet from Hell - unearths the horrifying details of one of the most prolific child sexual abuse offenders the NCA has ever investigated – Matthew Falder. Sadly, there are more than 830,000 adult offenders in the UK, using ever-more-sophisticated digital tools in an attempt to remain anonymous. Host Ellie Flynn speaks with psychologists, the Crown Prosecution Service and the NCA officers who caught Falder after years of evading capture to show the lengths teams went to to catch such a horrific offender.
