Meet the Psychopaths - Episode Guide

The first episode looks at psychopathic criminals, including Joanna Dennehy, who murdered three men, and Dennis Nilsen, one of Britain's most notorious killers.

Professor Tony Maden explores what happens when psychopaths gain positions of power. Examples include Jimmy Savile and Robert Maxwell.

Forensic psychiatrist Professor Tony Maden focuses on what makes psychopaths different from the rest of the population, examining the case of Mick Philpott, whose arson attack on his family home in Derby in May 2012 resulted in the deaths of his six children. Maden also explores how psychopathic personality traits can be socially valuable, with surgeon Gabriel Weston admitting to being able to turn off emotions during work, as does a bomb-disposal expert.
