I'm not sure if there is a specific 'Holmes and Smart Dr Watson' fantasy novel that is widely known. There are many Holmes - related works, but this title doesn't ring a common bell. It could be a relatively unknown or self - published piece.
You can watch the complete set of the TV series "Everything About Doctor Tang" on Mango TV.

Maybe it could involve Holmes and Watson using their detective skills in a fantasy world filled with magic and mythical creatures. They might solve mysteries related to ancient spells or magical artifacts.
In the TV series Ode to Joy, Guan Ju 'er and Doctor Zhao did not end up together. At the end of the novel, Qu Xiaoxiao and Dr. Zhao got together while Guan Ju 'er left the city and returned to the countryside.
Well, Irene Adler stands out. She was a strong and intelligent woman in a time when women were often not shown in such a way. She was able to best Holmes in a way. Professor Moriarty is another. His devious mind and his power made him a formidable foe for Holmes. And Mary Morstan, Watson's wife, was also an important character. Her presence changed Watson's life and added a different dimension to the stories.
