Murder at the Post Office (2025): A Gripping Documentary on Wrongful Conviction and the Post Office Scandal

A Yorkshire postmistress found dead. A husband convicted of her murder. A plea of innocence that echoes across 15 years. Murder at the Post Office is a compelling three-part documentary series that reopens one of the UK's most troubling criminal cases, examining whether the infamous Horizon system—the technology at the center of the Post Office Scandal—may have played a role in a potential miscarriage of justice.

In 2010, postmistress Diana Garbutt was murdered at her family's post office in Yorkshire. Her husband, Robin Garbutt, was arrested, tried, and convicted in 2011.

Now, as the Post Office Scandal continues to unravel and questions mount about the Horizon system's reliability, this documentary series investigates whether Robin's case deserves a second look. What really happened that day, and could flawed technology have contributed to a wrongful conviction?
