Enola Holmes 3 on Netflix: Millie Bobby Brown and Henry Cavill Deliver the Best Mystery of the Summer

Millie Bobby Brown and Henry Cavill reunite for the sharpest installment yet in Netflix's beloved mystery franchise.

If you've been craving a smart, fun detective movie to kick off your summer streaming marathon, Enola Holmes 3 just dropped on Netflix — and it might be the best entry in the series since the 2020 original. Millie Bobby Brown is back as the fiercely independent younger sister of Sherlock Holmes, and this time the stakes are higher, the mystery is darker, and the chemistry between her and Henry Cavill's Sherlock has never been better.

A Wedding Gone Wrong in Malta

The film picks up with Enola traveling to the sun-soaked island of Malta to finally marry her beloved Lord Tewkesbury, played once again by Louis Partridge. But this is Enola Holmes we're talking about — things never go according to plan. When Sherlock mysteriously vanishes during the wedding festivities, Enola puts her own happily-ever-after on hold to track him down. What she uncovers goes far beyond a simple missing-person case: a sprawling military cover-up that puts both siblings in serious danger.

Why This One Works

Director Harry Bradbeer, who helmed the first two films, returns behind the camera and clearly knows what makes this franchise tick. The pacing is tighter than Enola Holmes 2, the humor lands without feeling forced, and the Malta setting gives the whole thing a gorgeous Mediterranean vibe that's a welcome change from the foggy London streets.

Millie Bobby Brown continues to prove she was born for this role. She brings vulnerability and fierce determination in equal measure, and her comedic timing — especially in scenes where Enola breaks the fourth wall to address the audience directly — is sharper than ever. Henry Cavill, meanwhile, gets significantly more screen time this go-around, and their sibling dynamic is the emotional backbone of the film.

The Supporting Cast Delivers

Louis Partridge brings genuine warmth to Tewkesbury, and Helena Bonham Carter returns as the eccentric Eudoria Holmes in a smaller but memorable role. The new additions to the cast hold their own, particularly the villains who feel more menacing than anything we've seen in the series before.

Is It Worth Your Time?

Absolutely. At just under two hours, Enola Holmes 3 is the perfect weekend watch — entertaining enough for a movie night, smart enough to keep you guessing, and charming enough that you'll be hoping Netflix greenlights a fourth installment. If you loved the Nancy Drew energy of the first film or the expanded world-building of the second, this one delivers both in spades.

Stream it now on Netflix. Your watchlist will thank you.
