Brian Cox stars as McLevy with Siobhan Redmond as Jean Brash and Michael Perceval-Maxwell as Mulholland in this BBC Radio 4 full-cast dramatisation. Inspired by the real-life memoirs of a Victorian Inspector in Scotland, James McLevy prowls the dark streets of 1860s Edinburgh bringing criminals to justice, with the assistance of Constable Mulholland. In 'Jack O'Diamonds', Jean Brash plans revenge on a sadistic client, but the malign Mr Caleb Grant has a finger in every criminal pie in Edinburgh and is not a man to cross lightly. Written by David Ashton. Directed by Patrick Rayner.
