Netflix keeps expanding its library of whodunits, but The Final Problem arrives with a self-aware twist: the central detective is not Sherlock Holmes, but an actor remembered for playing him. The four-episode miniseries premiered on September 25, 2026, and is drawn from a novel by acclaimed Spanish-language writer Arturo Pérez-Reverte, not from Arthur Conan Doyle’s original stories.
That distinction gives the show room to play. It borrows the familiar outlines of a Sherlockian puzzle while remaining free to comment on the genre and the business of performing a famous character. That meta layer is likely to appeal most to viewers who have grown up on Sherlock Holmes adaptations and enjoy spotting references.
What happens in The Final Problem
Benjamin Basil, years past his success as an on-screen Holmes, accepts what he believes is a new role and travels to a luxury hotel on a small island near Majorca. He is joined by nine other people, and the group soon finds itself with no boat service and no radio contact. When a guest’s apparent suicide begins to look less straightforward, Basil starts investigating—leaning on the deductive habits he developed while playing the great detective.
- Release: September 25, 2026, on Netflix
- Length: Four episodes, easy to finish in a single day
- Source material: A novel by Arturo Pérez-Reverte, not a Conan Doyle adaptation
- Setting: A 1950s island hotel with a Golden Age cinema feel
Why it stands out
The setup may bring to mind And Then There Were None or Knives Out, because an isolated location and a death among strangers are mystery staples. The Final Problem, however, wears those conventions lightly. Its bigger interest is in the romance of cinema: an ageing actor rediscovering the spirit of his craft while the show itself echoes the look and grammar of classic detective films.
Basil has a companion in Foxá, a crime novelist and a loose Watson figure, though the relationship does not try to copy the original duo. The series spreads suspicion widely enough that every guest—including Basil—can seem like a possible culprit, even as the locked-room formula avoids becoming predictable. The show also plants Holmes references—including in Basil’s name and the series title—for viewers who enjoy catching callbacks.
Why it is an easy yes for a weekend watch
The tone is light, elegant and transportive. Instead of dark forensic detail or violent tension, the show favours conversation, deduction and style, all set in 1950s surroundings. For viewers deciding between a new theatrical release and a streaming drop, its four-episode length makes it a realistic one-day watch, and the mystery stays just far enough ahead to hold attention without becoming grim.
If you love Sherlock Holmes but want something warmer than a modern thriller, this is a weekend pick that offers clever references, a satisfying ending and a gentle reminder of why the detective still endures.
