31 Must-Watch British Crime Shows to Stream Right Now (January 2026)

It’s no spoiler to reveal that Ruth Ellis (Lucy Boynton), the lead character in the new four-episode crime show A Cruel Love,  died by hanging on July 13, 1955. Ruth was a real woman who committed a very real crime: She shot her lover, David Blakely (Laurie Davidson), on Easter the year of her death. But what led the nightclub hostess to carry out such a horrible act?

That’s the question behind A Cruel Love, BritBox’s excellent true-crime drama that explores Ruth’s motivations behind David’s murder, the subsequent trial that dominated the tabloid press and her death by execution, which is still the last time a woman was put to death for her crimes in the United Kingdom. 

This story has been told before, most notably in the 1985 film Dance with a Stranger, but never as absorbing and detailed as it is here. As Ellis, Boynton is never better playing a woman left with few options in life. The show convincingly evokes a period when scandal could ruin reputations and a crime of passion could captivate a still-innocent public.
