In the season two finale of Channel 4's Welsh drama Light in the Hall: Still Waters, the mystery of who murdered Llyr more than 30 years ago was finally solved. Convicted killer Rhys Owen, played by Mark Lewis Jones, was exonerated after serving 22 years for a crime he did not commit.
Who Killed Llyr?
Aspiring journalist Caryl (Sian Reese-Williams) had been receiving threatening texts urging her to stop investigating Llyr's death. In the finale, she was summoned to an abandoned warehouse, where she came face to face with the real killer: Llyr's sister Megan (Mali Tudno Jones).
Megan confessed that she killed her brother during an argument in 1995. She explained, "I loved my brother so much. And for a long time, it was just him and me. But he wouldn't stop. I didn't have a choice." She struck Llyr with bolt cutters, intending only to injure him, but the blow proved fatal. The reservoir explosion that followed was set by Llyr himself; Megan had been trying to stop him.
Aftermath and Arrest
Following her confession, Megan was arrested by her own husband, Gareth (Matthew Gravelle). Meanwhile, Rhys confronted his father Bryn (Wyn Bowen Harries), who admitted he had lent Llyr Rhys's tools, which explained Rhys's fingerprints on the bolt cutters. Bryn had initially planned to help with the bombing but backed out, leaving Llyr as the sole perpetrator of the explosion.
With his name cleared, Rhys decided to remain in Llanemlyn with his father, while Megan faced a lengthy prison sentence. The Western Herald was eager to publish Caryl's story, but she hesitated, fearing it would hurt people. Rhys encouraged her, saying, "You say you care about the community, do your job."
The Light in the Hall is available to watch on Channel 4.
