The game is afoot, and it’s more thrilling than ever! Enola Holmes 3, the highly anticipated third chapter in Netflix’s wildly popular mystery franchise, has officially wrapped filming, and fans are buzzing with excitement. Starring Millie Bobby Brown as the whip-smart, convention-defying younger sister of Sherlock Holmes, this latest installment promises to be the most daring yet, plunging Enola into a treacherous case that blends personal stakes with global intrigue. Set to hit Netflix in 2026, the film takes Enola to the sun-soaked yet sinister shores of Malta, where she’ll tackle her most complex mystery to date. With a stellar cast, a new director bringing a darker edge, and Brown’s magnetic performance at its core, Enola Holmes 3 is shaping up to be the clever, chaotic, and utterly unmissable adventure fans have been waiting for. Here’s why this film is already generating feverish anticipation.

A New Case, A New Horizon

Since her debut in 2020, Enola Holmes has carved out a unique space in the Sherlockian universe, blending Victorian-era sleuthing with a modern, feminist twist. The first film saw Enola, played with effervescent charm by Millie Bobby Brown, searching for her missing mother, Eudoria (Helena Bonham Carter), while outwitting her famous brother, Sherlock (Henry Cavill). The 2022 sequel had her launching her own detective agency, tackling a case inspired by the 1888 matchgirls’ strike and cementing her as a force to be reckoned with. Now, Enola Holmes 3 takes the young detective far from London’s foggy streets to the Mediterranean island of Malta, where “personal and professional dreams collide in a case more tangled and treacherous than any she has faced before.”

The official synopsis teases a mystery that flings Enola into a “nest of vipers,” suggesting a web of deception that tests her sharp mind and fearless spirit. While plot details remain tightly guarded, the setting in Malta—filmed in the historic cities of Valletta and Mdina—promises a visually stunning backdrop of ancient fortresses, azure waters, and shadowy alleys. Enola’s journey will intertwine her detective work with her evolving romance with Tewkesbury (Louis Partridge), the young viscount who’s now a member of the House of Lords. Expect high-stakes sleuthing, heart-pounding action, and a deeper exploration of Enola’s growth as she navigates love, danger, and her own ambitions in a world that underestimates her at every turn.

Millie Bobby Brown: A Star in Her Element

At just 21, Millie Bobby Brown is a powerhouse, and her portrayal of Enola Holmes is a masterclass in balancing wit, vulnerability, and grit. Known for her breakout role as Eleven in Stranger Things, Brown brings a different kind of intensity to Enola—a chatterbox who’s always one step ahead, breaking the fourth wall with a cheeky grin to pull viewers into her chaotic world. In Enola Holmes 3, she’s not just starring but also producing through her company, PCMA Productions, alongside her husband, Jake Bongiovi, who serves as an executive producer. Her Instagram post announcing the wrap, captioned “Case closed,” featured behind-the-scenes glimpses of her in costume, radiating excitement alongside co-stars and crew.

Brown’s Enola is the heart of the franchise, a young woman who defies Victorian gender norms with her intelligence, jujitsu skills, and unapologetic independence. This time, her character faces a darker, more mature challenge, with sources hinting at a tone akin to Harry Potter and the Prisoner of Azkaban—a pivotal shift that deepened that franchise’s emotional stakes. Brown’s ability to convey Enola’s evolution—from a sheltered teen to a confident detective—has fans buzzing, with one X post declaring, “Millie IS Enola. She’s going to crush this darker vibe!” Whether she’s cracking codes, dodging danger, or wrestling with her feelings for Tewkesbury, Brown’s performance is set to be the film’s beating pulse.

A Cast Packed with Heavy Hitters

Enola Holmes 3 boasts a returning ensemble that’s as formidable as its mysteries. Henry Cavill reprises his role as Sherlock Holmes, bringing his brooding charisma to the iconic detective. While Sherlock took a backseat in the sequel to focus on Enola’s agency, his presence here promises a dynamic interplay, especially with the introduction of Dr. John Watson, played by Himesh Patel. Patel’s brief appearance at the end of Enola Holmes 2, setting up Sherlock’s flatmate, hinted at a fresh partnership, and fans are eager to see how this trio navigates their latest case. Will Sherlock and Enola finally team up, or will sibling rivalry rear its head?

Helena Bonham Carter returns as Eudoria Holmes, the radical matriarch whose feminist ideals shaped Enola’s fierce spirit. Carter’s eccentric, commanding presence adds depth to the Holmes family, and her scenes with Brown are sure to spark with emotional resonance. Louis Partridge is back as Tewkesbury, Enola’s love interest, whose boyish charm has matured into a more grounded, political figure. Their romance, described as moving to “the next stage,” will add a layer of personal stakes to Enola’s adventure, balancing heart with her high-octane sleuthing.

Sharon Duncan-Brewster reprises her role as Moriarty, the cunning villain who escaped prison in Enola Holmes 2’s mid-credits scene. Her return signals a formidable foe for Enola, with her shadowy schemes likely tied to the “nest of vipers” in Malta. Adeel Akhtar and Susie Wokoma are expected to return as Inspector Lestrade and Edith, respectively, adding their own flair to the ensemble. There’s also hope for Sam Claflin’s return as Mycroft Holmes, the eldest sibling absent from the sequel due to scheduling conflicts. Director Harry Bradbeer previously noted an “open invitation” for Claflin, and fans are crossing their fingers for a Holmes family reunion.

A Darker, More Mature Vision

The biggest shift for Enola Holmes 3 comes behind the camera, with Philip Barantini (Boiling Point, Adolescence) taking over from Harry Bradbeer, who directed the first two films but remains a producer. Barantini’s vision, described as darker and more mature, aims to elevate the franchise much like Prisoner of Azkaban did for Harry Potter. His work on Adolescence, a critically acclaimed Netflix series, showcases his knack for blending intensity with emotional depth, making him a perfect fit for Enola’s next chapter. Jack Thorne, who penned the first two films, returns to write the script, adapting Nancy Springer’s The Enola Holmes Mysteries with an original story that diverges from the books, much like the sequel’s matchgirls’ strike plot.

Filming, which wrapped on June 27, 2025, took place at Shepperton Studios in the UK and on location in Malta’s Valletta and Mdina, where the island’s historic architecture and Mediterranean allure set the stage for Enola’s most dangerous case yet. The darker tone promises more complex villains, higher stakes, and emotional challenges for Enola, who’s no longer just a plucky teen but a detective coming into her own. Fans on Reddit are speculating about potential plots—could Enola face a betrayal from someone close, or will Moriarty’s schemes threaten her family? Whatever the case, the shift to a grittier narrative has sparked excitement, with one fan tweeting, “A darker Enola Holmes? I’m SO ready for Millie to break hearts and solve crimes!”

Why Enola Holmes 3 Is a Must-Watch

The Enola Holmes franchise has been a Netflix juggernaut, with the first film racking up 76 million household views in its first month and the sequel topping charts in 93 countries. Both films earned critical acclaim, boasting 91% and 93% on Rotten Tomatoes, respectively, for their blend of action, humor, and feminist themes. Enola Holmes 3 builds on this success, offering a fresh setting, a bolder tone, and a cast that’s pure dynamite. Brown’s star power, amplified by her work in Stranger Things and The Electric State, makes her the perfect anchor for a series that celebrates brains over brawn and girl power over outdated norms.

The film’s Maltese backdrop adds a new flavor, trading London’s gaslit streets for sun-drenched intrigue, while its focus on Enola’s romance with Tewkesbury gives it a coming-of-age heart. Barantini’s direction and Thorne’s script promise a mystery that’s both twisty and emotionally resonant, with Enola facing challenges that test her wit and resilience. Social media is ablaze with anticipation, with fans posting, “ENOLA HOLMES 3 WRAPPED. BEST DAY OF MY LIFE!” and “Millie and Louis in Malta? This is gonna be epic!” The film’s blend of adventure, romance, and danger makes it a perfect escape for viewers of all ages.

A Case Worth Waiting For

While an exact release date remains unconfirmed, the production timeline—filming began in April 2025 and wrapped in June—suggests a premiere in Q2 2026, following the pattern of its predecessors. With editing underway and Netflix’s knack for fast-tracking hits, Enola’s next adventure could arrive sooner than expected. Brown’s involvement as both star and producer, alongside Legendary Entertainment’s Mary Parent, Ali Mendes, and Alex Garcia, ensures a polished, high-energy film that builds on the franchise’s legacy.
