What is The Final Problem about?
The story of The Final Problem takes place in the spring of 1959. Thirteen people become stranded on a small island near Mallorca after a powerful storm makes it impossible to leave.
The group is staying at a hotel that initially seems peaceful. However, everything changes when Elisa Mander, an English tourist, is found dead.
At first, the circumstances suggest suicide. Still, several details soon raise questions about what really happened.
Among the guests is Benjamin Basil, an actor whose career has seen better days. Best known for playing Sherlock Holmes, Basil notices unusual details at the scene and begins to suspect that the death may actually be a murder.
As a result, the actor must stop pretending to be a detective and become one in real life.

An isolated hotel and plenty of suspects
Isolation is one of the main elements The Final Problem uses to build its suspenseful atmosphere.
The storm prevents the guests from leaving the hotel. At the same time, outside help is delayed, leaving everyone practically alone with a possible killer.
From that point on, anyone could be a suspect.
Each guest holds information that could completely change the direction of the investigation. As Benjamin tries to discover what happened to Elisa, new details emerge and increase the tension among everyone trapped at the hotel.
The series therefore follows a classic locked-room mystery structure, where clues, secrets, and suspicious behavior may be essential to uncovering the truth.

Benjamin Basil becomes a real-life detective
Benjamin Basil is at the center of The Final Problem. For years, he played Sherlock Holmes and became famous for portraying the legendary detective on the big screen.
However, his career is going through a difficult period when he arrives in Mallorca. The trip is supposed to help him find new professional opportunities, but the mysterious death at the hotel completely changes his plans.
Although Benjamin is not a real investigator, he has spent much of his life portraying someone capable of solving crimes through logic and observation.
Because of that, he begins studying the guests’ behavior, contradictions, and the small clues scattered throughout the hotel.
At the same time, the miniseries plays with the difference between acting like a detective and actually having to solve a murder. This time, Benjamin has no script telling him who the killer is.
A story based on Arturo Pérez-Reverte’s novel
The Final Problem is based on the novel of the same name by Spanish author Arturo Pérez-Reverte, known for stories that combine literature, adventure, history, and mystery.
The adaptation preserves many elements associated with classic detective fiction. It also features clear references to Sherlock Holmes and to traditional mysteries in which several suspects remain trapped in the same location.
The 1959 setting reinforces this approach. Without smartphones, the internet, or modern investigative technology, Benjamin has to rely mainly on observation, logic, and the information provided by the other guests.
Because of this, every conversation may hide an important clue.
Who is in the cast of The Final Problem?
José Coronado plays Benjamin Basil, the actor who unexpectedly takes on the role of investigator during the events at the hotel.
The cast of The Final Problem also includes María Valverde, Martiño Rivas, Gonzalo de Castro, Pepón Nieto, Cristina Kovani, José Condessa, Daniel Holguín, Michael Stobbe, and Maribel Verdú.
The wide range of characters is essential to the mystery because everyone staying at the hotel may know something about Elisa’s death.
With so many possible suspects, Benjamin has to separate coincidences, lies, and real clues as he tries to reconstruct what happened.
How many episodes does The Final Problem have?
The Final Problem is a four-episode miniseries. The episodes follow the investigation from Benjamin’s arrival in Mallorca to the final revelations surrounding the events at the hotel.
The first episode introduces the characters and quickly transforms Benjamin’s trip into an unexpected investigation.
After that, new clues emerge and Benjamin becomes increasingly involved in the case.
As the story moves forward, distrust among the guests grows. At the same time, events connected to the past begin to play a bigger role in solving the mystery.
A classic mystery with plenty of suspense
Viewers who enjoy classic whodunit stories will find many familiar elements in The Final Problem.
There is an isolated location, a mysterious death, several suspects, and a protagonist who must find answers before the situation becomes even more dangerous.
The Spanish setting and 1950s atmosphere also give the production its own identity.
Instead of relying on large action sequences, the miniseries focuses on clues, conversations, and the growing distrust between the characters.
As a result, each episode adds new questions while Benjamin tries to piece together the truth.
Who should watch The Final Problem?
The Final Problem may appeal especially to viewers who enjoy crime suspense, investigative stories, and literary adaptations.
It can also be a good choice for fans of productions inspired by the style of Sherlock Holmes and mysteries set in locations where anyone could be guilty.
In addition, with only four episodes, the miniseries tells a relatively short story. That makes it a convenient option for viewers looking for a mystery they can finish in just a few episodes.
The Final Problem is available to stream on Netflix.
