The Game Is Afoot in 'The Final Problem' Trailer
An actor famous for playing Sherlock Holmes is asked to solve a murder. What could go wrong?
Netflix has released the trailer for its Spanish-language adaptation of The Final Problem, a delightfully offbeat Sherlock Holmes adaptation that sees an actor known for playing the Great Detective try to solve a real-life murder in a remote, inaccessible location.
Based on the 2023 novel by Arturo Pérez-Reverte, the story is set in the spring of 1959 and follows thirteen people trapped by a violent storm on an island near Mallorca. (Shades of Agatha Christie, anyone?) When a British tourist mysteriously turns up dead, the group turns to Benjamin Basil to solve the crime. Basil isn’t a detective, however, merely famous for playing one at the cinema. He’s known for his performance as Holmes, and basically that is enough to convince the other guests that he has a chance at figuring out whodunnit. With a little help from aspiring thriller writer Foxá (Martiño Rivas) as his would-be Watson, Basil will have to channel every skill his most famous role possesses to save the day.
The series mixes a lush period setting with a twisty murder mystery, and boasts a sly sense of humor and self-awareness about the genre it’s poking fun at. (Basil is, of course, named after Basil Rathbone, one of the most famous actors to ever don a deerstalker.)
Here’s the series’ synopsis.
During the spring of 1959, thirteen people were isolated by a storm on a small island near Mallorca. No one imagines what is about to happen in the small hotel where they are staying: Elisa Mander, a discreet tourist of English origin, is found dead. What initially seems to be a suicide soon begins to show signs of being something much more disturbing: a murder. Basil, a retired actor who once portrayed none other than Sherlock Holmes on the big screen, will find himself, almost unintentionally, tasked with unraveling what happened. In a place from which no one can leave and to which no one can arrive, all the guests and employees will become suspects of a crime that, with each passing moment, reveals itself to be more complex and convoluted than anyone could have imagined at first.
Alongside Coronado and Rivas, the series also stars María Valverde (We Were Songs), Maribel Verdú (When Nobody Sees Us), Gonzalo de Castro (Politically Incorrect), Cristina Kovani (The Silence), José Condessa (Cocoa), and Pepón Nieto (Smiley).
Félix Viscarret (Don’t Look into Their Eyes) directs all five episodes from scripts adapted by Alberto Macías, Carlos Molinero, and Marisol Farré.
Fernando Bovaira (La Fortuna) produced the series for Mod Producciones, with Urko Errazquin (La vida padre) serving as executive producer.
The Final Problem premieres Friday, September 25, 2026, on Netflix.
