Enola Holmes 3 Trailer Just Dropped — Millie Bobby Brown's Final Adventure Goes to the Mediterranean

Netflix just dropped the full trailer for Enola Holmes 3 today (June 17, 2026), and if you thought the first two films were packed with twists, this one looks like it's turning everything up to eleven. The third and final installment in the beloved detective franchise arrives on July 1, 2026, and the trailer promises a sun-soaked Mediterranean mystery that puts Millie Bobby Brown's iconic sleuth in her most dangerous situation yet.

A Bigger, Bolder Mystery

Directed once again by Harry Bradbeer (Fleabag, Killing Eve) from a screenplay by Stranger Things creator Jack Thorne, Enola Holmes 3 takes the young detective far beyond the foggy streets of Victorian London. The newly revealed footage shows Enola tracking a high-stakes conspiracy that stretches across the Mediterranean, with stunning locations in Malta, Italy, and Greece serving as the backdrop for what might be her most complex case yet.

Henry Cavill returns as the legendary Sherlock Holmes, though the trailer hints that the brother-sister dynamic has shifted — this time, Enola seems to be calling the shots. Louis Partridge is back as Lord Tewkesbury, and from the looks of the trailer, the chemistry between him and Brown's Enola is stronger than ever. Helena Bonham Carter also makes a welcome return as Eudoria Holmes, Enola's free-spirited mother who brings her own brand of chaos to the story.

Why This One Feels Different

What makes Enola Holmes 3 stand out is the scale. Director Harry Bradbeer told press that this film was designed as a proper send-off for the character, with a mystery that genuinely raises the stakes. The villain, played by newcomer Jonathan Bailey (Bridgerton, Fellow Travellers), appears to be a charismatic political figure whose influence reaches the highest levels of European society.

The first two Enola Holmes films were massive hits for Netflix, with the 2020 original pulling in over 76 million views in its first four weeks. The sequel in 2022 didn't slow down, becoming one of the platform's most-watched films that year. Netflix is banking on the trilogy's finale to deliver that same energy — and judging by the trailer's visual ambition, they're not holding back.

The action sequences also look significantly upgraded. Expect parkour chases through Mediterranean port towns, a tense confrontation on a moving train, and a climactic scene involving a burning villa that looks straight out of a Bond film. Composer Daniel Pemberton (Spider-Man: Into the Spider-Verse, Project Hail Mary) returns with a score that blends orchestral thrills with the playful, modern energy that defined the previous films.

The Bottom Line

If you've been following the Enola Holmes series since 2020, this trailer is a reminder of why the franchise became such a cultural touchstone. Millie Bobby Brown has grown alongside the character, and Enola Holmes 3 looks like a fitting final chapter — bigger, smarter, and genuinely thrilling. Mark your calendars for July 1st on Netflix. This is one you'll want to watch the same day it drops.
