Clemency Burton-Hill recorded her journey after being left unable to speak or walk. Plus: the twist-filled season finale of Death in Paradise. Here’s what to watch this evening

9pm, BBC Two
“Music was my greatest ally, and now it’s like my toxic friend.” A film following the remarkable story of Clemency Burton-Hill, who was 38 years old when a brain injury left her unable to speak or walk. Before that, she was a violinist who had also achieved a double first from Cambridge and had a successful career as a broadcaster and writer. Through recordings from her early days of recovery, we trace an inspiring journey as she is reunited with her “ally”, the violin. Hollie Richardson
