Enola Holmes – Season 3 (2025) continues the thrilling adventures of Sherlock Holmes’ brilliant younger sister, offering a fresh blend of mystery, wit, and heartfelt coming-of-age drama. Set in late 19th-century London, the new season finds Enola (Millie Bobby Brown) stepping more firmly into her role as a detective in her own right, no longer overshadowed by her famous brother. But as her reputation grows, so do the dangers and responsibilities that come with it.
The season opens with Enola running her own detective agency, though clients remain hesitant to hire a young woman. Her fortunes change when she is drawn into a high-stakes case involving the disappearance of a radical suffragist whose campaign for women’s rights threatens to destabilize London’s elite. What begins as a missing-person case soon spirals into a web of political intrigue, blackmail, and betrayal that could reshape the future of the city.
Sherlock (Henry Cavill) returns in a more central role this season, but the dynamic between the siblings evolves. No longer mentor and pupil, they clash as equals—sometimes rivals, sometimes allies—each determined to pursue justice in their own way. Their partnership is tested when Sherlock uncovers evidence that suggests powerful forces within Parliament are orchestrating the crimes Enola is investigating. The tension between their methods and values adds both drama and warmth, deepening their sibling bond.
Tewkesbury (Louis Partridge) also reenters Enola’s world, their relationship now more mature but no less complicated. As an idealistic reformer working within the political system, Tewkesbury becomes entangled in the case, forcing Enola to confront both her feelings for him and the personal sacrifices required by her career. Their slow-burn romance intertwines with the central mystery, balancing danger with tenderness.
The season introduces new allies and adversaries, including a cunning rival female detective whose allegiance remains uncertain, and a shadowy industrialist willing to destroy anyone who threatens his empire. These additions expand Enola’s world while challenging her growth as a detective, pushing her to rely not just on intellect and bravery, but also on her ability to trust others.
By its conclusion, Enola Holmes – Season 3 delivers a story that is as thrilling as it is empowering. The resolution of the suffragist mystery not only cements Enola’s place among London’s greatest detectives, but also underscores the broader themes of justice, equality, and resilience. With fast-paced action, clever twists, and heartfelt character arcs, the new season reaffirms that Enola Holmes is more than Sherlock’s little sister—she is a hero in her own right, ready to shape her destiny in a world that underestimates her at its peril.
