The Adventures of Sherlock Holmes and Dr. Watson: Mortal Fight (1980)

Dr. Watson executes Sherlock Holmes' will, who faced death after exposing Moriarty and his gang in the previous episode.

Faced with two false confessions and numerous suspects after a despised civil magistrate is found shot in the local vicarage, Detective Inspector Slack reluctantly accepts help from Miss Marple.

Early in his crime-solving career, Sherlock Holmes attempts to prevent Moriarty from cornering the heroin market.

Dr. Watson, who served in the English armed forces and was in the Afghan war, retires and returns to his homeland, in England. Since the financial situation of the doctor is very precarious, his long-time friend Mr. Stamford offers him to rent a room in the house at 221-B Baker Street, which is rented by an elderly lady - Mrs. Hudson. The second rented room is already occupied by another gentleman - the mysterious Mr. Sherlock Holmes. Holmes makes an ambiguous impression on Watson. He conducts complex chemical experiments with blood, plays the violin, has the deepest knowledge about cigar ash, London dirt and criminal law, but at the same time demonstrates complete ignorance of well-known truths (for example, the fact that the Earth revolves around the Sun), does not read fiction, as well as books on history and philosophy. At the same time, very strange visitors constantly come to Holmes, and on the table he has portraits of personalities of a disgusting appearance.

At the insistence of Ruth Van Rydock, an old schoolfriend who is convinced that there is something wrong, Miss Marple agrees to visit 'Stonygates', the country house of Ruth's sister.

During a murder hunt game at a country house, to which Hercule Poirot is invited as an "expert", a real murder occurs.
