Murder by Decree (1979)

Synopsis
The murders by the infamous British criminal, Jack the Ripper, catch the attention of Sherlock Holmes (Christopher Plummer), but he does not receive the expected call from Scotland Yard because he is being purposefully excluded from the investigation. Instead, Robert Lees (Donald Sutherland), a psychic who volunteered information to the police about the murders, provides the Great Detective with the necessary incitement to action. As the murders proceed, it becomes clear to all concerned that it is more important to stop them than to announce their solution, and Holmes enters the fray with the help of his trusty aide, Dr. Watson (James Mason). The former mistress of a "prominent personage," Annie Crook (Genevieve Bujold), provides crucial information leading to a final confrontation on London's docks. ~ Clarke Fountain, All Movie Guide
