Miss Scarlet And The Duke - Season 4 〈RELIABLE × Edition〉

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.

So, is the Duke gone for good? Not entirely. Martin appears in a limited capacity, acting as a narrative bridge. The season premiere cleverly writes Wellington out by having him accept a prestigious position at the New York Police Department. This transatlantic move leaves Eliza (Kate Phillips) utterly alone in London. Miss Scarlet and the Duke - Season 4

The season ends with Eliza standing on the roof of her agency, looking out over a smoky London. Blake is downstairs waiting to take her to a new case. Ivy is baking a cake in the kitchen. The Duke’s desk is gone. The game has changed

This moment defines Season 4. Eliza Scarlet is no longer a girl waiting to be chosen. She is a woman deciding who is worthy of her partnership. By the finale, she kisses Blake—not with passion, but with calculation. It is a kiss of acceptance, not surrender. The final episode brings the Duke back for one crucial scene. William Wellington returns to London to collect his remaining belongings. Seeing Eliza running the agency with Blake by her side, the Duke has a moment of quiet devastation. Stuart Martin plays this with heartbreaking subtlety—a single tear, a forced smile, and a goodbye that feels permanent. Not entirely

To survive, Eliza takes a case involving a missing aristocrat’s daughter. This case forces her to team up with the one man she swore she never would: Alexander Blake (Tom Durant-Pritchard), a charismatic, roguish ex-convict turned informant. If the Duke is order, Alexander Blake is chaos. Introduced as a morally grey fixer with a silk scarf and a silver tongue, Blake is the most dangerous addition to Season 4. He isn't interested in rules; he is interested in results.
