Murder mysteries remain a cornerstone of Netflix’s catalog, offering more than mere suspense through layered deceptions that challenge even the sharpest minds. Among the genre’s legendary detectives, Sherlock Holmes stands apart, and the streaming platform now presents a fresh interpretation in the miniseries The Final Problem.
Though not a direct adaptation of Arthur Conan Doyle’s stories, The Final Problem serves as a loving homage to the classic mystery tradition. Premiering on September 25, 2026, the series draws from a novel by acclaimed Spanish-language author Arturo Pérez-Reverte and follows a seasoned actor, well beyond his prime as a screen Holmes, who is drawn into investigating a genuine murder when opportunity arrives far from the spotlight.
At first glance, The Final Problem appears to follow familiar whodunit conventions, evoking comparisons to classics like And Then There Were None and Knives Out. Yet through its visual style, character dynamics, and carefully placed easter eggs, the series functions as a genuine tribute to the mystery genre and the Golden Age of cinema.
The story begins when actor Benjamin Basil, lured by the promise of a new role, becomes stranded at a luxury hotel on a small island near Majorca, cut off from boats and radio contact alongside nine other guests. When a fellow resident’s suicide raises suspicions, Basil must rely on everything he learned from years of portraying Sherlock Holmes to uncover the killer’s identity and protect the remaining guests before law enforcement arrives.
The series reimagines familiar mystery tropes without growing predictable. Although it employs the classic locked-room setup and isolates its suspects, The Final Problem maintains suspense throughout. Basil is assisted by crime novelist Foxá, but their relationship deliberately avoids replicating the Holmes-Watson dynamic; instead, the narrative scatters clues among every guest on the island, including Basil himself.
The series transports viewers to the 1950s, evoking the golden age of cinema through its camera angles and brief flashbacks of a younger Basil performing as Sherlock Holmes. These sequences mirror the visual language of classic detective films. The homage to Holmes extends to Basil’s very name and the series title, while his constant references to the detective’s methodology make uncovering clues an engaging exercise for longtime fans of Arthur Conan Doyle’s work.
The Final Problem Reinvigorates the Classic Mystery Formula
The Final Problem does not seek to reinvent the genre or deliver a shocking twist, but its strength lies in maintaining suspense until the final act without descending into the grim tone of modern thrillers. It explores themes tied to the film industry and its era, including social class disparities, all while preserving a lighthearted atmosphere.
Elegant and stylistic, The Final Problem favors conversation over forensic grit, setting its deductions against a picturesque backdrop where characters sip coffee and unravel clues through pure reasoning. At its core, the series explores cinematic nostalgia, following an actor who once gave his life to a role as he rediscovers his craft. Spanning just four episodes with a satisfying conclusion, it offers an easy single-day watch that reminds viewers why they love Sherlock Holmes.
