Until I Kill You (2024) is a British true crime series based on Delia Balmer’s book, Living With A Serial Killer (2017).

Set in London during the 1990s, Delia Balmer (Anna Maxwell Martin) is a nurse who has a live-in relationship with a violent man, John Sweeney (Shaun Evans).

In Episode 3, Delia has recovered – physically – from an assault by Sweeney. One day she meets a kind, gentle man called David (Kevin Doyle) who was an adoptee.

In Episode 4, David supports Delia as she gives evidence in court against Sweeney. The couple subsequently split up and we don’t see David again.
