Signs of Murder: A Small Town in Scotland, a Miscarriage of Justice and the Search for Truth

Before David Wilson became the UK's pre-eminent criminologist, he was just a young boy growing up in the Scottish town of Carluke. When he was a child, the brutal murder of a young woman rocked this small community, but very quickly a man was arrested for the crime, convicted and put behind bars. For most, life slowly carried on - case closed.

But there were whispers in the town that the wrong man was imprisoned. Over the years, these whispers grew louder, to the point that any time David would visit, he'd be asked in hushed tones, 'What are you going to do about the Carluke Case?'

Carluke believed the real killer had evaded justice. A murderer was still on the loose.

Forty years later, it's time for David to return home, and find out the truth.
