Netflix is officially gearing up for the return of its fan-favorite detective duo — Millie Bobby Brown as Enola Holmes and Henry Cavill as Sherlock Holmes. After the global success of Enola Holmes (2020) and Enola Holmes 2 (2022), the streaming giant has confirmed the development of Enola Holmes 3, which is expected to mark the final chapter in this acclaimed mystery franchise.
The Enola Holmes series has become one of Netflix’s strongest original properties, blending period drama, mystery, and modern sensibilities. Based on Nancy Springer’s popular novels, it follows Enola, the younger sister of Sherlock Holmes, as she builds her identity as an independent detective in Victorian England.
Henry Cavill’s Return as Sherlock Holmes
After months of speculation, multiple entertainment sources have confirmed that Henry Cavill will officially return as Sherlock Holmes in Enola Holmes 3. Cavill’s portrayal of Sherlock — calm, intelligent, and quietly emotional — has been widely praised for bringing warmth and humanity to the character, without overshadowing Enola’s journey.
According to early reports, Enola Holmes 3 will give Sherlock a larger and more personal storyline. Instead of just being a supportive figure, Cavill’s Sherlock will face his own inner conflicts and challenges as he partners with Enola on a case that tests both their intellect and their bond as siblings.
Millie Bobby Brown Leads the Final Mystery
At the heart of the story remains Millie Bobby Brown, who continues to establish herself as one of Netflix’s biggest global stars. In Enola Holmes 3, she will portray a more mature version of Enola — a confident and renowned detective facing her toughest mystery yet.
Sources close to the production reveal that the new film will explore a powerful political conspiracy in Victorian London. A mysterious disappearance connected to the British government pulls Enola into a dangerous investigation, forcing her to rely on Sherlock like never before.
The film is expected to explore deeper emotional themes — family, trust, and independence — while maintaining the wit, charm, and adventurous tone that made the previous two installments fan favorites.
Storyline and Tone of Enola Holmes 3
Director Harry Bradbeer, who helmed the first two films, will return to direct the third installment. Screenwriter Jack Thorne is also back to continue the narrative.
According to early creative discussions, Enola Holmes 3 will have a darker and more cinematic tone, with higher stakes and a more emotionally layered story.
The movie will likely begin with Enola running her own detective agency, gaining recognition after the events of Enola Holmes 2. When a high-profile figure vanishes under mysterious circumstances, Enola and Sherlock’s investigations collide — leading them to uncover a conspiracy that threatens the stability of London itself.
The story will focus not only on the mystery but also on the relationship between Enola and Sherlock, exploring how two brilliant minds from the same family handle their differences while working toward a common goal.
Cast and Production Updates
The confirmed returning cast includes:
- Millie Bobby Brown as Enola Holmes
- Henry Cavill as Sherlock Holmes
- Louis Partridge as Viscount Tewkesbury
- Helena Bonham Carter as Eudoria Holmes
Filming for Enola Holmes 3 is expected to begin in mid-2025, once Millie Bobby Brown wraps up her other Netflix commitments. The movie is likely to premiere globally on Netflix in 2026.
Why Fans Are Excited
The Enola Holmes series has been praised for its blend of mystery, humor, and social commentary. It delivers a fresh take on the Sherlock Holmes universe by focusing on a strong female lead who defies the gender norms of her time.
Fans particularly admire the on-screen chemistry between Henry Cavill and Millie Bobby Brown — a dynamic that balances logic with emotion. Cavill’s calm portrayal of Sherlock perfectly complements Millie’s energetic and rebellious Enola, creating a family connection that resonates deeply with viewers.
Industry analysts believe that Enola Holmes 3 will not only serve as a satisfying conclusion but also stand as one of Netflix’s biggest releases in 2026. With growing global anticipation, Netflix is expected to give it a large marketing push similar to Stranger Things and The Witcher.
Conclusion
Enola Holmes 3 is shaping up to be a powerful and emotional conclusion to Netflix’s most beloved detective saga. Combining Henry Cavill’s final portrayal of Sherlock Holmes with Millie Bobby Brown’s bold and evolving character, the film promises to deliver mystery, action, and heartfelt drama in equal measure.
With production likely beginning in 2025 and a release in 2026, fans can expect a grand finale that celebrates intelligence, courage, and the legacy of the Holmes family.
