The Hound of the Baskervilles When Sir Charles Baskerville is killed outside of Baskerville Hall, his good friend Dr. Mortimer (Lionel Atwill) fears that the curse of the Baskerville has struck once again. Mortimer enlists the help of Sherlock Holmes (Basil Rathbone), before yet another Baskerville can succumb to the evil legend. Pursuit to Algiers (1945) begins as Holmes and Watson learn that the King of Ravenia has been assassinated and his son Nikolas is now a marked man. The great detective and his comrade are pressed into service to protect the life of the soon-to-be crowned monarch.
