Enola Holmes 3: Cast, Review and That Ending Explained (2026)

Enola Holmes 3 landed on Netflix on July 1, 2026, sending Millie Bobby Brown’s teenage sleuth to sun-baked Malta for a wedding that almost immediately turns into a kidnapping case. It’s a starrier, higher-stakes finale that ties off the Moriarty storyline and Enola’s romance with Lord Tewkesbury — though critics have been distinctly lukewarm. Here’s the full cast, an honest look at the reviews, and a complete spoiler breakdown of that twisty ending. The cast and review sections are spoiler-free; the ending breakdown is clearly flagged before the spoilers begin.

Who’s in the Enola Holmes 3 cast?

The core ensemble all return, with one big change behind the camera: Philip Barantini (of Adolescence) takes over as director from Harry Bradbeer, who made the first two films, while writer Jack Thorne stays on. Here’s who’s who.

What is Enola Holmes 3 about?

Without spoilers: the film opens with Enola, now an established detective, having second thoughts on her wedding day. She’s in Malta to marry Lord Tewkesbury when her brother Sherlock is abruptly kidnapped, forcing her to abandon the ceremony and race to find him. The trail pulls her into a darker, more tangled case than any before — one that spans a Mediterranean conspiracy and the shadier corners of the British Empire — while she also wrestles with what marriage would mean for her hard-won independence. It’s a change of scenery and tone from the London-set originals, leaning into thriller territory over the series’ usual breezy adventure.

Is Enola Holmes 3 any good? The reviews

Honestly? This one has landed as the weakest of the trilogy for many critics. The broad consensus is that the first two films, under Harry Bradbeer, had a galloping, playful energy that made even their thin plots fly by, whereas Barantini’s threequel feels slower and more generic — one widely shared verdict is that where the earlier films were appealingly exhausting, this one just feels exhausted. Reviewers have praised the cast, and Sharon Duncan-Brewster in particular is singled out for praise, but several argue the Moriarty character is underwritten and that Enola, now a seasoned sleuth, has lost some of the underdog spark that made her distinctive. If you’re a fan of the franchise and the cast, there’s still fun to be had and a tidy send-off; just temper expectations if you’re hoping it matches the highs of the first film.

Enola Holmes 3 ending explained (spoilers ahead)

Spoiler warning: this section reveals the full ending. The mystery turns out to be Moriarty’s long game. Released from prison by corrupt army officials on the promise of recovering a fortune in hidden gold, Mira Troy needed someone with intimate knowledge of the Tewkesbury family to find it — so she engineered the whole thing. Through a spy, she planted the idea of a Malta wedding, then kidnapped Sherlock and left a trail of clues (Morse code spelling “Khost,” lace, and the late Lord Tewkesbury’s medals) specifically to lure Enola into solving the puzzle for her.

The rescue plays out in Moriarty’s lair, where Sherlock and Tewkesbury’s mother, Lady Tewkesbury, are being held. Enola frees her future mother-in-law, who in turn frees Sherlock, while Enola takes on Moriarty herself. The film’s biggest character beat comes next: Sherlock gets Moriarty at gunpoint and, knowing she’ll only escape prison to torment the family again, seriously considers pulling the trigger. Enola talks him down, insisting that a Holmes doesn’t kill and that he can’t let his emotions win. He relents — though Lady Tewkesbury gets a satisfying blow in, cracking Moriarty over the head with a rock. Moriarty is left seemingly lifeless, but it’s later revealed she survives and will be moved to a prison she’s fully expected to break out of eventually, keeping the door open for a return. Her arrest also blows the wider conspiracy wide open, leading to the arrest of the officials who freed her.

The shipwreck twist, the wedding, and will there be Enola Holmes 4?

The cleverest wrinkle is the one clue Enola actually misses. Throughout the case she chases a woman she believes is “Adeline Rathe,” only for the film’s final image — the wreckage of a ship — to reveal that Adeline Rathe was never a person at all. It was a coded pointer to the shipwreck where the gold was hidden. The point is thematic: even a mind as sharp as Enola’s can overlook something, yet she still cracks the case her own way rather than by any tidy Holmes formula.

As for the wedding, the film bookends itself neatly. The lavish Malta ceremony collapses when Sherlock is taken, and it emerges that Enola’s cold feet were never about love but about identity — her fear of losing the Holmes name and her independence by becoming a viscount’s wife. The resolution lets her have both: a smaller, second wedding where she marries Tewkesbury as he renounces his title, so she remains a Holmes on her own terms. On a possible Enola Holmes 4, nothing is officially confirmed, but the pieces are there — Millie Bobby Brown has said she’d return if Netflix wants it, there are ten Nancy Springer novels to draw from, and leaving Moriarty alive is about as clear a sequel hook as it gets.

The bottom line

Enola Holmes 3 is a warmer-looking, higher-stakes but slower send-off that closes the loop on Moriarty and finally gets Enola and Tewkesbury to the altar on her own terms — even if critics feel it never recaptures the zip of the original. The ending keeps things hopeful and deliberately open, with Moriarty out there and the door ajar for a fourth film.
