Encounters with Evil Episode Rating Graph

This opening episode of new true crime series Encounters With Evil delves deep into the dark world of those that kill, not for revenge or in a fit of rage - but just for the sheer thrill of it. British serial killer Denis Nilsen - who murdered at least fifteen people - took sexual pleasure from killing and kept the corpses in his home for as long as possible as a twisted form of 'company'.

A look at three cases of psycho killers, incapable of empathy or remorse. These include Joanna Dennehy, who murdered three men in a ten day killing spree.

This episode investigates four cases in which girls and young women are held against their will, often for many years.
