Iain takes us to 1908 Glasgow, where 83-year-old Marion Gilchrist is found murdered in her Glasgow flat. A missing brooch and a fleeing spark a transatlantic manhunt, and decades of fighting for justice.

But this isn't just a story of a manhunt. What unfolds is one of Scotland's most controversial trials, where prejudice, weak evidence, and a famous detective novelist collide.
