Henry Cavill’s Sherlock Holmes Faces His Darkest Challenge Yet in Enola Holmes 3

A newly surfaced report has sparked excitement among fans of Netflix’s Enola Holmes franchise, suggesting that the upcoming third installment will place Henry Cavill’s Sherlock Holmes in unprecedented danger. According to the rumor, the legendary detective may find himself completely outmatched by a cunning new adversary, forcing him to rely on his younger sister Enola more than ever before.

The report claims that Enola Holmes 3 will introduce a formidable villain named Mira Troy, portrayed by Sharon Duncan-Brewster. While her true identity remains shrouded in mystery, she is allegedly operating under the infamous alias “Moriarty,” a name that instantly raises the stakes for Sherlock Holmes fans. Known in literary history as Holmes’ greatest enemy, Moriarty has always represented a threat capable of matching the detective’s brilliance. In this new adaptation, Mira Troy appears ready to continue that tradition in terrifying fashion.

According to the rumor, Moriarty’s plan begins with a calculated attack on Sherlock himself. Rather than confronting him directly in a battle of wits, she reportedly orchestrates an elaborate scheme that results in his capture. Sherlock is said to be kidnapped and secretly transported to a remote prison located in Malta, far away from the streets of London where he normally holds the advantage. Isolated from his allies and stripped of his freedom, the world’s most famous detective suddenly becomes the victim rather than the investigator.

The alleged imprisonment creates an entirely new dynamic for the franchise. In the previous films, Sherlock often served as a mentor-like figure who admired Enola’s intelligence while occasionally offering guidance. This time, however, the roles may be reversed. With Sherlock trapped and unable to solve the mystery himself, Enola becomes the family’s only hope of uncovering Moriarty’s plot and bringing her brother home.

As rumors suggest, Enola’s journey leads her to Malta, where the film’s central mystery unfolds. The Mediterranean island provides a dramatically different backdrop from the foggy Victorian streets featured in earlier installments. Ancient fortresses, hidden tunnels, rugged coastlines, and isolated prison complexes are expected to play major roles in the story. These locations could transform the film into a globe-spanning adventure filled with danger at every turn.

While searching for Sherlock, Enola reportedly uncovers clues that reveal Moriarty’s larger ambitions. Rather than targeting a single individual, the villain may be manipulating influential figures across Europe, building a network of power through blackmail, deception, and carefully orchestrated crimes. As Enola digs deeper into the conspiracy, she begins to realize that Sherlock’s kidnapping was only the first move in a much larger game.

The report further claims that the story culminates in a dramatic confrontation between Enola and Moriarty. Their showdown allegedly takes place in a canyon-like landscape on the outskirts of Malta, providing a visually striking setting for the final battle. Unlike the intellectual contests often associated with Sherlock Holmes stories, this encounter reportedly becomes intensely physical. Enola and Moriarty engage in a fierce fight, testing not only Enola’s intelligence but also her courage and determination.

During the struggle, Enola gains the upper hand and delivers a powerful kick to Moriarty’s head. However, rather than accepting defeat, the villain allegedly executes one final trick. Moriarty reportedly stages her own death, disappearing from sight and leaving everyone to believe she has perished. This twist would allow the character to evade justice while simultaneously laying the groundwork for future stories. If true, it would echo the classic cat-and-mouse relationship traditionally associated with Sherlock Holmes and Moriarty.

Netflix’s official synopsis confirms at least part of the adventure, revealing that Enola will travel to Malta during the film. The studio describes the story as one in which “adventure chases detective Enola Holmes to Malta,” where personal ambitions and professional responsibilities collide during her most dangerous investigation yet. Although the synopsis does not mention Sherlock’s imprisonment, it aligns with reports suggesting a high-stakes international mystery.

Millie Bobby Brown returns to lead the franchise as the sharp-witted young detective. Following the events of the second film, Enola is no longer simply trying to establish herself. She has already built a reputation and proven her capabilities. This new chapter reportedly explores a more mature version of the character as she begins questioning her future and deciding what kind of detective—and person—she wants to become.

Brown previously hinted that Enola enters a phase that is more defined yet still evolving. The character faces important personal questions while balancing increasingly complex responsibilities. Her emotional journey becomes even more significant through her relationship with Tewkesbury, played once again by Louis Partridge. Their connection is expected to deepen, adding emotional weight to the larger mystery.

Henry Cavill also returns as Sherlock Holmes, though the rumored storyline suggests his screen presence may take a very different form this time around. Rather than confidently solving cases from his Baker Street residence, Sherlock could spend much of the film struggling to survive imprisonment while searching for a way to escape. This situation would reveal a more vulnerable side of the iconic detective, demonstrating that even the greatest minds can be caught off guard by the right opponent.

Returning cast members include Helena Bonham Carter as the unconventional and fiercely independent Eudoria Holmes, as well as Himesh Patel as Dr. Watson. Their involvement could prove crucial as Enola assembles allies to track down Sherlock and uncover Moriarty’s scheme.

Behind the scenes, Enola Holmes 3 marks a significant creative change. Philip Barantini takes over directing duties, replacing Harry Bradbeer, who helmed the first two movies. The screenplay is once again written by Jack Thorne, adapting characters and ideas from Nancy Springer’s beloved book series. Barantini and Thorne previously collaborated on Netflix’s acclaimed series Adolescence, leading many fans to expect a darker and more emotionally intense tone for the third installment.

Production on the film reportedly began in England in April 2025 before moving to Malta for additional filming. The Mediterranean locations are expected to play a central role in shaping the film’s atmosphere and visual identity. Brown later confirmed that principal photography concluded in June 2025, signaling that the project moved smoothly through production.

Although Netflix has not officially confirmed the rumored plot details regarding Sherlock’s kidnapping or Moriarty’s involvement, the report paints a compelling picture of what could be the franchise’s most ambitious chapter yet. If the rumors prove accurate, Enola Holmes 3 may deliver a thrilling blend of mystery, action, family drama, and international intrigue. Most importantly, it could finally place Enola at the center of a case so dangerous that even Sherlock Holmes himself cannot solve it alone.
