The game has changed. For three seasons, fans of the hit PBS Masterpiece series Miss Scarlet and The Duke have been hooked not only by the intricate Victorian-era whodunits but also by the tantalizing, slow-burn chemistry between its two titular characters: the fiery, independent female detective Eliza Scarlet and the stoic, rule-bound Scotland Yard Inspector William "The Duke" Wellington.
However, arrived with a seismic shift that left audiences reeling. Gone is the familiar title card featuring the two leads staring longingly at each other. In its place is a leaner, meaner, and surprisingly bold narrative that proves this show is willing to sacrifice romance for realism. Miss Scarlet and the Duke - Season 4

Stream it on PBS Masterpiece or Amazon Prime Video. Just bring tissues—not for the mystery, but for the goodbye.
This was a high-risk gamble for the writers. The "will-they-won't-they" tension was the emotional engine of the show.

The police force, led by a new antagonist, Detective Inspector Fitzroy (played by a menacing Cal MacAninch), views her as a nuisance.
