Whether your favorite recent mystery has been one of the Knives Out movies or one of the twisty seasons of Only Murders in the Building, a well-developed crime mystery can make for gripping television. After introducing its characters, a sudden death gives them a new purpose as the lead detective, or a team of investigators, follows clues, questions suspects and eventually identifies the killer. The familiar formula still makes for compelling viewing.
One recent series built around this kind of mystery is Netflix’s <em>The Final Problem</em>. The Spanish series, released on September 25, 2026, is based on a novel by Arturo Pérez-Reverte and combines period drama with a murder investigation.
