While visiting old client Sir Henry Baskerville, Sherlock Holmes (Arthur Wontner), aided by Dr. Watson (Ian Fleming), solves two killings and the disappearance of a horse. Professor Moriarty (Lyn Harding) and helper Colonel Moran are involved in the plot in this thriller, acting on behalf of a bookie who wants the favored horse to lose in an upcoming race. Arthur Wontner’s final film as the great detective is a good entry in the series, but familiarity with the original short story may weaken its impact.

  Mildly recommended. Otto judiciously thinks this movie is OK, but not great.

Movie 39 for 2021.
