As of October 2023, "Enola Holmes 3" has not been officially confirmed, but there is speculation about its potential due to the popularity of the first two films. "Enola Holmes 2," released in November 2022, continued the story of Sherlock Holmes' younger sister, played by Millie Bobby Brown. While there are no concrete announcements regarding a third installment, fans are hopeful for more adventures featuring Enola. Keep an eye on news from Netflix or the filmmakers for any updates.

In "Enola Holmes 2," there is no explicit indication that Enola marries Tewksbury. The film focuses on Enola's adventures as a young detective and her journey toward independence. While there are romantic undertones in their relationship, the story emphasizes her growth and self-discovery rather than concluding with a marriage. The film leaves their relationship open-ended, allowing for future possibilities without confirming a romantic commitment.

"Enola Holmes 2" is not based on a true story; it is a fictional narrative inspired by the book series by Nancy Springer. The film continues the adventures of Enola Holmes, the younger sister of Sherlock Holmes, as she embarks on a new case. While the characters are drawn from Arthur Conan Doyle's iconic Sherlock Holmes universe, the specific events and plots in "Enola Holmes 2" are creative inventions rather than historical occurrences.

As of my last update in October 2023, there hasn't been any official announcement regarding the filming locations for "Enola Holmes 3." However, the previous films were primarily shot in the UK, particularly in locations around London.
