Enola Holmes 3 Confirmed for July 2026 on Netflix — Millie Bobby Brown Returns as Sherlock's Witty Sister

Enola Holmes 3 Is Officially Coming to Netflix This July

Good news for mystery lovers and millennials who grew up watching Millie Bobby Brown break the fourth wall — Enola Holmes 3 is officially set to premiere on Netflix in July 2026. That's a full four years after Enola Holmes 2 dropped back in 2022, but trust us, it's going to be worth the wait.

Based on Nancy Springer's The Enola Holmes Mysteries book series, the franchise has become one of Netflix's most beloved original film properties. The first movie premiered in 2020 during the pandemic and became an instant hit, racking up over 76 million household views in its first month.

What We Know About Enola Holmes 3

Millie Bobby Brown returns as the titular character, the sharp-witted younger sister of Sherlock Holmes (played by Henry Cavill). Helena Bonham Carter is also expected to reprise her role as their mother, Eudoria Holmes. The film is directed by Harry Bradbeer, who also helmed the first two installments.

The trailer, which just dropped this week, hints at a more dangerous case for Enola — one that takes her beyond the English countryside and into the darker corners of Victorian London. Based on the book series, this installment is expected to draw from The Case of the Gypsy Queen, the fifth novel in Springer's series.

Why Millennials Can't Miss This

The Enola Holmes franchise has always hit differently for millennials. It's part mystery, part coming-of-age story, and part feminist statement — all wrapped in gorgeous period costumes and a killer soundtrack. Millie Bobby Brown also serves as a producer on the film, proving she's not just acting but building her empire behind the camera too.

With Legendary Entertainment and the PCMA Productions banner producing, the production values are only going up. The first two films combined for over 200 million views on Netflix, making this one of the platform's most successful film franchises ever.

Bottom line: Mark your calendars for July 2026. Enola Holmes is back, and she's bringing the whole gang with her.
