The chilling real-life events recounted by Delia Balmer in her memoir 'Living With a Serial Killer' are set to unfold on ITV in the drama 'Until I Kill You'.
Delia, who was an agency nurse in London, encountered Sweeney at a bar, leading to a relationship that proved not only toxic but perilous.
After moving into Delia's residence, Sweeney unleashed a campaign of terror, at one point holding Delia captive for four days by binding her to her bed and issuing threats.
In a harrowing episode, he lunged at her with an axe and knife, inflicting severe injuries that would take years for Delia to recover from.
