The suicide of a mysterious young woman and the murder of two men appear to be inextricably linked. When Dr. Joseph Bell is asked to assist the police, it soon becomes clear that this is more than just a routine case. Dr Bell's relationship with the Chief of investigation is put in the spot light as old resentments come to the surface jeopardising a quick conclusion to the murders. Bell calls in Arthur Conan Doyle for support, but when Doyle seems to side with the Chief rather than his mentor, cracks start to appear in their long friendship. Can Joseph Bell's extraordinary powers of deduction reveal that there is more to this case than meets the eye? Or will he be proved wrong for the first time in his career?
