Sharon Duncan-Brewster portrays Moriarty in the Enola Holmes films.

In the Enola Holmes film series, Moriarty is a modern interpretation of the classic criminal mastermind created by Arthur Conan Doyle.
Unlike many previous adaptations, the Netflix films initially present the character as someone operating behind the scenes rather than immediately revealing their true identity. This allows the mystery to unfold gradually, fitting perfectly with Enola’s detective style.
The movies take creative liberties with the source material, giving Moriarty a unique backstory while preserving the character’s intelligence, manipulation, and ability to stay several steps ahead of everyone else.
Although Sherlock Holmes has faced countless dangerous criminals throughout his career, Moriarty has always been considered his greatest intellectual opponent, and the films continue to build toward that legendary rivalry.

Mira Troy Explained: The Genius Anagram
One of the absolute best twists in the movie is how Moriarty is hidden right in front of us. She is first introduced as Mira Troy, a seemingly unassuming secretary to the Treasury Minister, Lord Charles McIntyre.
Because she is a woman in Victorian London, the powerful men around her completly ignore her brilliance. She uses this to her advantage, orchestrating a massive criminal and blackmail network from the shadows. In the final act, the brilliant reveal happens: “Mira Troy” is an anagram for “I am Moriarty.” This creative liberty gives her a unique backstory while showing exactly how she weaponizes society’s blind spots.
Sherlock Holmes in Enola Holmes
The battle between Sherlock Holmes (played by Henry Cavill) and Moriarty is a clash between two of the greatest minds in fiction. Cavill’s Sherlock represents justice, logic, and deductive reasoning. Every mystery he solves depends on careful observation.
Moriarty represents the opposite side of genius. Rather than solving crimes, she orchestrates them. Their rivalry works becuase neither underestimates the other. Sherlock realizes he has finally met an opponent capable of matching his intellect, and the movie expertly lays the groundwork for this famous conflict.
Enola and the Supporting Characters
Unlike traditional stories, the Netflix films place Enola at the center. As Sherlock’s younger sister, Enola possesses remarkable observation skills and a willingness to challenge social expectations. Her investigations frequently overlap with larger conspiracies, bringing her into contact with Moriarty’s sprawling web.
The supporting characters are crucial here. From Tewkesbury’s political maneuvers to Inspector Lestrade’s Scotland Yard investigations, everyone plays a part in unraveling the mystery. Enola is no longer just watching Sherlock’s famous rivalry unfold—she is an active participant alongside her allies in events that shape the future of London’s underworld.
Moriarty Ending Explained
The ending of Enola Holmes 2 establishes just how dangerous Moriarty truly is. Rather than being an ordinary criminal, she is capable of planning elaborate schemes while remaining hidden until the perfect moment.
While she is initially caught, the mid-credits scene delivers a massive shock: Moriarty has successfully escaped police custody. This ending intentionally leaves room for future adventures. Instead of providing complete closure, it proves that Moriarty’s influence extends well beyond a single case, firmly setting her up as a returning antagonist.
