Netflix today announced the premiere date for The Final Problem , the new limited series starring Jose Coronado ( The Truthers , The Snow Girl ), María Valverde ( Sounds Like Love , All We Cannot See) , Martiño Rivas ( Snakes and Ladders , Cable Girls ), and Maribel Verdú ( Pan's Labyrinth , Elite ), among others. Based on the bestselling novel of the same name by Arturo Pérez-Reverte , The Final Problem will premiere on Netflix on September 25 .

In the spring of 1959, thirteen people find themselves stranded by a violent storm on a small island off the coast of Mallorca. No one could imagine what is about to unfold at the secluded hotel where they are staying: Elisa Mander, a quiet English tourist, is found dead. What initially appears to be a suicide soon reveals itself to be something far more disturbing a murder.

Basil ( Jose Coronado ), a retired actor who once portrayed Sherlock Holmes on the big screen, unexpectedly finds himself taking on the role of investigator. As suspicion spreads among the guest, including Adela Figueroa ( María Valverde ), a mysterious young woman travelling with a friend, he joins forces with Foxá ( Martiño Rivas ), an aspiring thriller writer, to search every corner of the luxurious hotel for answers, all while testing the composure of Mrs. Ausländer ( Maribel Verdú ), the hotel's manager.

In a place where no one can leave and no one can arrive, every guest and member of staff becomes a suspect in a crime that proves to be far more intricate and elusive than anyone could have imagined. The Final Problem is a sophisticated adaptation of one of Arturo Pérez-Reverte's bestselling novels, a period thriller filled with secrets, mystery, and unexpected twists.

The cast is rounded out by Gonzalo de Castro ( Políticamente incorrectos, La ternura ) as Fonseca, an ambitious film director, and Cristina Kovani ( Muted, La caza: Guadiana ) who plays a young and passionate actress. The ensemble also features José Condessa ( Cacau, Turn of the Tide) and Pepón Nieto ( Smiley, A Remarkable Tale ), among many others.

The miniseries is produced by Mod Producciones, with Fernando Bovaira ( While at War, La Fortuna) serving as producer, Urko Errazquin ( The Champion, Two Many Chefs) as executive producer, and Alberto Macías , Carlos Molinero , and Marisol Farré as screenwriters. It is directed by Félix Viscarret ( Una vida no tan simple, Staring at Strangers ).
