Killer Couples
About

Killer Couples examines four very different and peculiar cases, each involving a couple instead of the traditional single killer. In every episode we seek to understand what drove these couples to kill.
The vast majority of killers prey on their victims alone and undercover. Yet just occasionally, two people are drawn together to form a deadly duo. How and why does this happen?
Join internationally best-selling crime novelist and former TV actor Mark Billingham as he explores this horrific but fascinating phenomenon, looking at the crimes and motivations of very different killer couples.
He meets the friends who knew the couples, the detectives who caught them, and the psychologists and criminologists who have tried to understand them.
All the time Mark is building a picture of not only what took place, but more importantly: why? Through his investigations, we learn why these couples extraordinarily turned to murder together.
