As of May 2025, Enola Holmes 3 is currently in production, with filming taking place in the UK and Malta. While Netflix hasn’t announced an official release date, filming began in April 2025 and is expected to wrap by July. Considering the franchise’s previous timelines—where Enola Holmes 2 released about 18 months after its announcement—it’s unlikely the third film will premiere before the end of 2025. A more realistic window is early to mid-2026, possibly between March and June, although Netflix might opt for a later release to align with a strategic fall slot.

Enola Holmes 3 Expected cast

The Enola Holmes series thrives on its stellar ensemble, and Enola Holmes 3 brings back familiar faces. Here’s the expected cast:

  • Millie Bobby Brown as Enola Holmes: The heart of the franchise, Brown returns as the witty, fourth-wall-breaking detective. Her star power, bolstered by Stranger Things and Damsel, anchors the series.

  • Henry Cavill as Sherlock Holmes: Cavill reprises his role as Enola’s older brother, the iconic detective. His dynamic with Enola is a fan favorite, and he’s confirmed to return.

  • Helena Bonham Carter as Eudoria Holmes: The Holmes family matriarch, Eudoria, is back, bringing her eccentric and rebellious spirit.

  • Louis Partridge as Viscount Tewkesbury: Enola’s love interest and confidant, Tewkesbury, returns, with his relationship with Enola expected to deepen.

  • Himesh Patel as Dr. John Watson: Introduced in Enola Holmes 2’s post-credits scene, Patel’s Watson is confirmed to appear, likely teaming up with Sherlock and Enola.

  • Sharon Duncan-Brewster as Moriarty: The villainous Moriarty, who escaped prison in Enola Holmes 2, is set to return, promising chaos for the Holmes siblings.

Enola Holmes 3 Potential Plot

While Netflix is keeping the plot under wraps, the official synopsis and franchise trends offer clues about Enola Holmes 3’s story: “Adventure chases detective Enola Holmes to Malta, where personal and professional dreams collide on a case more tangled and treacherous than any she has faced before.”

The shift to Malta suggests an international mystery, possibly involving political intrigue or a high-stakes crime. This new backdrop could introduce exotic locations and cultural elements, differentiating it from the London-centric first two films.

The Enola Holmes films loosely adapt Nancy Springer’s The Enola Holmes Mysteries. The third book, The Case of the Bizarre Bouquets, centers on Dr. Watson’s disappearance and a cryptic bouquet symbolizing death. While Enola Holmes 2 diverged from the books, Enola Holmes 3 may draw elements from this novel, especially since Watson is now in the mix. Enola and Sherlock might race to find Watson, clashing or collaborating.
