Murder at the Post Office

In 2010, the quiet Yorkshire village of Melsonby was shaken when postmistress Diana Garbutt was found brutally murdered in the flat above the post office she ran with her husband, Robin Garbutt. Suspicion swiftly fell on Robin, and in 2011 he was convicted of her murder—a verdict he has consistently denied.

Years later, the credibility of the Horizon computer system, central to the wider Post Office Scandal, comes under intense scrutiny. This documentary re-examines the original investigation, the evidence used to secure Robin’s conviction, and the systemic failures surrounding Horizon. As new questions emerge, the film asks whether justice was truly served—and if Robin Garbutt’s case could finally be reopened.
