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 'Picture of Innocence', a high court judge is dead and suspicion falls on his wife. Her alleged adultery with a fashionable portrait painter suggests a strong motive for murder, but she protests her innocence and turns to McLevy for help. Written by David Ashton. Directed by Patrick Rayner.
