The game is afoot—again. Netflix has dropped the bombshell fans have been waiting for: Enola Holmes 3 is officially on the way, set to premiere on the streaming giant in summer 2026. Millie Bobby Brown reprises her role as the fiercely independent teenage detective, Sherlock Holmes’ younger sister, in what promises to be the most ambitious and emotionally charged installment yet. Henry Cavill returns as the iconic Sherlock, bringing his brooding intensity and razor-sharp intellect back to the screen. Together, they deliver a Victorian-era adventure that blends high-stakes mystery, budding romance, family drama, and the kind of clever twists that have made this franchise a global sensation.

The announcement came as part of Netflix’s “Next on Netflix 2026” showcase, where the streamer unveiled its slate of upcoming films and series. A first-look image sent hearts racing: Louis Partridge’s Viscount Tewkesbury down on one knee, presenting Enola with a flower ring, her expression a perfect mix of shock and delight. The caption? “Millie Bobby Brown, Henry Cavill, Helena Bonham Carter, and Louis Partridge return in Enola Holmes 3, where Enola must crack life’s greatest mystery: love.” It’s a tease that hints at deeper personal stakes amid the usual criminal intrigue.

Filming wrapped in June 2025 after starting in April at Shepperton Studios in England, with additional shoots in the sun-drenched streets of Valletta and Mdina, Malta. Directed by Philip Barantini (known for the acclaimed Adolescence), the film shifts the action abroad for the first time. The official logline sets the stage: “Adventure chases detective Enola Holmes to Malta, where personal and professional dreams collide in a case more tangled and treacherous than any she has faced before.” This Mediterranean backdrop—ancient fortresses, azure seas, labyrinthine alleys—promises a visually stunning evolution from the foggy London streets of the previous films.

Brown, fresh from wrapping Stranger Things‘ final season, brings even more depth to Enola. Now in her late teens, the character has grown from a runaway girl into a confident detective running her own agency. Yet success comes with complications. Enola’s independence clashes with her evolving feelings for Tewkesbury, now a progressive member of the House of Lords. Their relationship, simmering since the first film, reaches a turning point. Partridge’s charming, idealistic Tewkesbury has matured too—political responsibilities weigh on him, but his devotion to Enola remains unwavering. The proposal in the first-look photo suggests romance is no longer subtext; it’s central.

Henry Cavill’s return as Sherlock is a major coup. After stepping away from the role of Superman, Cavill has embraced projects that let him showcase his range. His Sherlock is stoic yet protective, a brother who respects Enola’s brilliance even as he worries about her recklessness. Their sibling dynamic—equal parts rivalry, admiration, and unspoken affection—has been one of the franchise’s strongest elements. Cavill’s physical presence and commanding screen gravitas elevate every scene he’s in, whether delivering dry wit or racing through danger.

The supporting cast is stacked. Helena Bonham Carter reprises Eudoria Holmes, the free-spirited mother whose radical ideals shaped Enola’s worldview. Her appearances, though often brief, pack emotional punch. Himesh Patel returns as Dr. John Watson, introduced in the second film’s post-credits scene. Watson’s partnership with Sherlock adds warmth and grounding realism to the Holmes universe. Sharon Duncan-Brewster is back as the cunning Moriarty (Mira Troy), the criminal mastermind who escaped at the end of Enola Holmes 2. Her presence guarantees high-stakes villainy and intellectual cat-and-mouse games.

Jack Thorne, the Emmy-winning writer behind the first two films (and collaborator with Barantini on Adolescence), pens the script once more. Adapted from Nancy Springer’s The Enola Holmes Mysteries series, the third film takes creative liberties while staying true to the spirit of a young woman defying Victorian expectations. Thorne’s dialogue sparkles with humor, social commentary, and fourth-wall breaks—Enola’s direct addresses to the audience remain a signature charm.

What makes Enola Holmes 3 particularly exciting is its maturation. The first film introduced Enola’s world and her quest for independence. The second expanded her detective skills and introduced broader conspiracies. Now, the third delves into maturity: balancing career ambition with love, navigating family legacy, confronting the consequences of defying societal norms. The Malta setting amplifies this—far from home, Enola faces isolation, cultural clashes, and threats that test her limits. Rumors suggest political intrigue involving colonial tensions or ancient artifacts, blending historical fiction with pulse-pounding action.

The franchise’s success is undeniable. Enola Holmes (2020) became one of Netflix’s most-watched originals, praised for its feminist twist on the Holmes canon and Brown’s charismatic performance. Enola Holmes 2 (2022) built on that momentum, earning acclaim for its expanded scope and emotional depth. Both films hold strong Rotten Tomatoes scores and massive viewership numbers. With Brown’s star power (post-Stranger Things, post-Damsel), Cavill’s draw, and Netflix’s global reach, Enola Holmes 3 is positioned as a summer blockbuster on streaming.

Fans are buzzing. Social media erupted after the announcement—hashtags like #EnolaHolmes3 and #MillieBobbyBrown trended worldwide. Theories abound: Will Enola accept Tewkesbury’s proposal? How will Moriarty strike next? What role will Watson play in the mystery? The blend of romance, danger, and wit has viewers hooked.

Behind the scenes, the production exudes passion. Brown co-produces through PCMA Productions, ensuring Enola’s voice stays authentic. Legendary Entertainment handles the heavy lifting, with a team committed to quality. Barantini’s direction promises dynamic visuals—think sweeping Maltese vistas contrasted with shadowy intrigue.

As summer 2026 approaches, anticipation builds. Enola Holmes 3 isn’t just another sequel; it’s Enola claiming her legacy fully—detective, woman, sister, perhaps fiancée. With wit sharp as a deerstalker hat, danger lurking in every alley, and clever twists around every corner, this chapter promises to be unforgettable.
