It's a truth universally acknowledged that if one is a British actor of mature years, it is pretty much inevitable that one will play a detective on the telly. This is the case for Martin Clunes, who is best known for playing the irascible title character in Doc Martin, and who is now, at last, taking up the magnifying glass to do a bit of investigating.
Sir Arthur Conan Doyle (Clunes) is best-known as the creator of Sherlock Holmes and Doctor Watson, but he was also quite a sleuth himself. In 1903, Anglo-Indian solicitor George Edalji was arrested and jailed for a series of brutal attacks on animals. Three years later he was released, but the taint of the crime remained. He enlisted Sir Arthur Conan Doyle, who, after Kipling, was Britain's most famous author - to help clear his name. Along with his loyal secretary, Alfred Wood, Sir Arthur traipsed around the countryside, using his powers of deduction to track down the truth.
