World-famous author Sir Arthur Conan Doyle in this three-part adaptation of Julian Barnes' acclaimed novel follows the separate but intersecting lives of two very different men: a half-Indian son of a vicar who is framed for a crime he may or may not have committed, and Doyle, who investigates the case.

After the death of his wife, Sir Arthur Conan Doyle is presented with a real-life mystery involving a man claiming to be innocent of the charges against him.

ir Arthur Conan Doyle recaptures his zest for life by pursuing and challenging a notorious miscarriage of justice. In 1906, Sir Arthur Conan Doyle, having lost his first wife, was overcome with grief; even Sherlock Holmes and Dr Watson refused his call. It was only when his secretary, Woodie, presented him with an apparent real-life miscarriage of justice, that he could be roused to action. The case in question was that of George Edalji, a Parsee solicitor, who was imprisoned for writing obscene letters and killing livestock in Great Wyrley, Staffordshire. George needed Arthur's help to clear his name. However, as the twists and turns of the case unfold, Arthur himself questions George's innocence. It is only by finding the true culprit, that Arthur can finally put the case, and his grief, to rest; whilst simultaneously becoming influential in a major reform to the English judicial system.
