The Private Life of Sherlock Holmes

Watson described one of the Sherlock Holmes cases, but for various reasons did not publish it. Only 50 years after his death, the heirs were able to read the manuscript and learn about one of the failures of the famous detective.

Holmes, missing an interesting case. They are invited with Watson to a performance of the Russian ballet and a banquet after it. Holmes is offered to become the biological father of the child of a Russian ballet diva. The detective has no desire to enter into a love affair with her and tells the ballerina that he prefers men. Watson, upon learning about this, is very angry, because he is afraid for his reputation.

The intrigue of the film begins with the fact that a cabman delivers a young woman with amnesia to Holmes' apartment, whom he fished out of the river where she was drowning. Friends try to question her, but she doesn't remember anything. In a semi-delirium, a woman takes Holmes for her husband, but he, being a gentleman, does not show physical attraction to her. Sherlock Holmes undertakes to help a woman find her missing husband.

He is summoned by Mycroft, Holmes' brother, who works for the government, and warns that he should not take up this case. But Sherlock does not obey. He, Watson and a young lady who introduced herself as Gabrielle Voladon are together trying to find a trace of her missing husband. They find out that the letters addressed to her husband come to an empty store in which an elderly woman in a wheelchair is caring for canaries. There they find out that they need to go to Scotland.

On the way, they encounter a group of monks. In Scotland, the heroes find two dwarfs, three bleached canaries and a Voladon killed. In the hotel, from the balcony overlooking Loch Ness, Watson sees a monster.

Later it turns out that Sherlock's brother Mycroft is involved in the construction of a submarine for the British Navy with the assistance of Voladon. To hide the tests, the ship was disguised as a monster. The dwarfs, whose disappearance Holmes had read earlier, were recruited as crew members, since they took up less space and needed less air. During the meeting, Mycroft informs Sherlock that his client is actually the main German spy, Ilse von Hoffmannsthal, who was sent to steal a submarine engine. The monks turn out to be German sailors.

Queen Victoria arrives to inspect the new weapon, but does not approve of the development, stating that it is not gentlemanly to shoot from under the water at the enemy and England will never do so. She orders an enraged Mycroft to destroy the ship. He leaves the boat unattended, so it is not difficult for the monks to steal it. After a while, the boat explodes due to a gas leak. Ilse von Hoffmannsthal is arrested for further exchange for a British spy.

In the final scene a few months later, Sherlock receives a message from his brother saying that von Hoffmannsthal was arrested as a spy in Japan and subsequently executed. The heartbroken detective goes to his room.
