The Best Murder Mystery TV Shows of 2026

Agatha Christie's Seven Dials

A fresh 1920s-set adaptation following Superintendent Battle as he investigates a murder tied to a secret society. For fans of the classic country-house whodunit, this is the most faithfully Golden Age entry on the list — closed circle of suspects, a methodical detective, and a properly fair-play solution.

Only Murders in the Building, Season 6

The true-crime-podcasting trio returns for another Manhattan mystery. What keeps this show fresh five-plus seasons in is its willingness to keep reinventing its own format while never losing the comedy-mystery balance that made it a breakout hit in 2021.

Scarpetta

An adaptation of Patricia Cornwell's long-running novel series, following medical examiner Kay Scarpetta across dual timelines. A more forensic, procedural take on the genre than the cozy entries on this list, and a strong pick if you prefer your mysteries grounded in investigative detail over drawing-room deduction.

The Puzzle Lady

A British cozy mystery in the Midsomer Murders tradition, built around a crossword-enthusiast amateur sleuth solving crimes in a small town. Low on violence, high on charm — a good pick for viewers (or hosts) who prefer their whodunits gentle.

Young Sherlock

A teenage Sherlock Holmes investigates his first real case in a story that leans into origin-story world-building as much as the mystery itself. Worth watching for how it reframes detective fiction's most iconic character for a new generation.

Also Worth Watching

The Lincoln Lawyer, Season 4 and Dark Winds, Season 4 both return with strong new murder-driven seasons, leaning more character-driven and procedural than puzzle-box, for viewers who want their mystery wrapped in richer drama.

Why This Genre Keeps Growing

Every one of these shows is doing a version of what murder mystery games have always done: hand the audience a closed set of suspects and a fair chance to solve it themselves. If a show on this list has you hooked, that's exactly the itch a live murder mystery party scratches — you get to be a suspect instead of just watching one.
