Shaun Evans and Anna Maxwell Martin to Lead True Crime Drama 'Delia Balmer'

With the ninth and final season of Inspector Morse prequel Endeavour set to arrive in the U.K. in just a few weeks and then headed to America this summer, star Shaun Evans is looking for what's next or him as an actor. And after playing the famous detective for a solid decade, he's shaking things up --- by taking on the role of an infamous killer on the other side of the law.

Evans is set to star in Delia Balmer, a true crime drama about the extraordinary woman who survived a relationship with infamous serial murderer John Sweeney, a carpenter from Liverpool who killed and dismembered two of his girlfriends in 1990 and 2000 before dumping their bodies in canals in Rotterdam and London. The former young Morse will be playing Sweeney, a role that's certainly a rather significant swerve from the opera-loving crime solver that he's made his name as in recent years.

Line of Duty star Anna Maxwell Martin will play the eponymous Balmer, who met Sweeney in a London pub in 1991. The two began dating, but over time their relationship became increasingly unstable as he grew violent and controlling. And when he confessed to killing his previous girlfriend, she began to live in a state of constant fear that she herself could be next.
