Murder Rooms on tonight on BBC4

One of Matthew Macfadyen's earlier works is on tonight (Saturday 26 September, 2009) on BBC4 at 21:05

Drama inspired by the real-life relationship between Arthur Conan Doyle and his tutor, pioneering forensic pathologist Dr Joseph Bell. The two embark on a grisly and disturbing case dealing in death, drugs and disease in the highest circles and lowest depths of Edinburgh.
