Roku has ordered Scarlett Holmes, a limited series that casts Lucy Hale as a descendant of Sherlock Holmes who applies the family’s famed powers of observation to love instead of crime.
Hale also executive produces the show, which debuts exclusively on The Roku Channel in 2027. Her character inherits the deductive gifts of her ancestor but uses them to untangle clients’ romantic problems, from mixed signals to secret crushes. She works alongside her sidekick, Jane Watson.
Her own love life proves harder to crack. Scarlett falls for Ollie Moriarty, a charming podcast producer who is secretly preparing an exposé on her methods, setting up what the logline calls her toughest case. Each episode takes inspiration from a classic romantic comedy.
Paris Herbert-Taylor, whose credits include On the Roam, and Katie Wilbert of A Vineyard Christmas wrote the series. Jaggi Entertainment produces and handles international sales, with Sophie Tilson and Steve Jaggi serving as executive producers alongside Hale. Morgan Pichinson and Sabrina Lyall oversee the project for Roku. Hale is the only cast member announced so far, and the company has not set a premiere date.
Brian Tannenbaum, head of Roku Originals, praised Hale’s “wit, warmth and comedic instincts” and described the show as a playful mix of two genres his streamer’s audience loves, romance and mystery. Hale called herself “a true diehard fan of romantic comedies” and said the project has the quality that drew her to the genre.
The series fits a pattern for Roku, which has leaned into light, rom-com-flavored originals as its free, ad-supported channel competes for viewers. The company has also put a romantic comedy called Cowboy Hearts, starring Kristin Cavallari as a reality TV producer, into development.
Hale, who rose to fame on Pretty Little Liars, most recently starred in the 2024 thriller F** Marry Kill*. Sherlock Holmes has proven a durable franchise for reinvention, from Netflix’s Enola Holmes films to modern updates on television, and Scarlett Holmes bets that the premise can sustain one more.
