Until I Kill You: A unique true crime drama about a singular person

Delia Balmer, the protagonist of ITV’s true-crime drama Until I Kill You, is a singular sort of person. She’s a “traveller”, not a “tourist”; a “female” never a “woman”, with the sharpest of tongues.

Balmer, played by Anna Maxwell Martin, is isolated. Living alone in a run-down flat in London’s Kentish Town in 1991, she is virtually friendless at the hospital where she works as a nurse, and her family lives overseas.
