What happens at the end of Enola Holmes 3?
Enola Holmes 3 landed on Netflix on 1 July 2026 and went straight to number one — sending Millie Bobby Brown's detective to Malta for a wedding that turns into her biggest case yet. Here's how it all ends, spoilers and all.
The short answer
Moriarty is behind everything. Sherlock's kidnapping was a trap designed to make Enola find a hoard of Afghan gold stolen during the Battle of Khost. Enola defeats her, the gold is returned to Afghanistan, Moriarty survives to fight another day — and yes, Enola and Tewkesbury finally get married.
The mystery, unpacked
Sherlock (Henry Cavill) vanishes on the morning of Enola's wedding, leaving the word "Khost" on his mirror. The trail leads to a decades-old military cover-up:
- The gold — stolen from an Afghan shrine during the Anglo-Afghan War, then hidden in Malta after Tewkesbury's late father refused to hand it over.
- The conspiracy — orchestrated by Brigadier Sampson, Tewkesbury's godfather, with the governor and senior officers keeping it buried for decades.
- "Professor Adeline Rathe" — the mysterious mastermind, revealed to be Moriarty (Sharon Duncan-Brewster), freed from prison by corrupt officials to recover the gold. The alias wasn't even a person: the final shot reveals a sunken ship called The Wrath of Adeline, where the treasure lay hidden.
The showdown
Enola frees Lady Tewkesbury, who frees Sherlock, while Enola fights Moriarty herself. The film's biggest beat: Sherlock holds Moriarty at gunpoint and seriously considers killing her, knowing prison won't hold her. Enola talks him down — a Holmes doesn't kill. Lady Tewkesbury then flattens Moriarty with a rock anyway.
The villain survives, is arrested, and is shipped to a prison she's fully expected to escape. The corrupt officials, Sampson included, are exposed and arrested, and the gold goes back to Afghanistan.
Do Enola and Tewkesbury actually marry?
They do — on her terms. Enola's wobble was never about love; it was about losing the Holmes name she'd spent six years earning. So Tewkesbury gives up his title, they take his non-lord family name, Tebbity-Gore, and marry in a small ceremony officiated by Enola's fugitive mother, Eudoria (Helena Bonham Carter).
Writer Jack Thorne was careful with the Malta backdrop, telling Netflix's Tudum in 2026 that "Enola is not the hero that saves Malta" — the island's independence story belonged to its people.
Is Enola Holmes 4 happening?
Not officially confirmed — but Moriarty is alive, Millie Bobby Brown has said she'd return, and there are ten Nancy Springer novels to draw from. That door isn't closed. It's wedged open.
