Will There Be a 'Miss Scarlet & The Duke' Season 5?

Miss Scarlet & The Duke Season 4 is the show's most dramatic and potentially controversial season yet. The popular will they/won't they tension between the series' titular leads finally tipped firmly into blatantly romantic territory, as William straight-up admitted he loved Eliza and the pair finally (!!!) shared a kiss. Of course, all of this happened literally moments before William announced he was leaving to spend a year in America and though we've gotten a vague update on how he's doing there (thanks, Ivy!), there's a very real chance the character won't even appear in the finale at all. (Star Stuart Martin isn't in any of the promotional photos that have been released from the episode, and it seems unlikely that the show would suddenly jump forward a year in time in the space of a week.)

What I'm saying is that it's extremely likely this season of Miss Scarlet will end with the romantic status of our two main characters still in limbo, and without any confirmation about whether or not the show itself will continue. As of this writing, the show has yet to be renewed for a fifth season, a terrifying prospect for fans who have suddenly been gifted with everything they've ever wanted but who must now confront the possibility that they may not get to see the romance they've been waiting for since the show's first episode actually play out onscreen if the show doesn't return for future episodes.

Season 5 feels like it should be a given. Miss Scarlet & The Duke is a hit for both Masterpiece and Alibi. The show performs well on both broadcast and streaming. Its stars and creatives seem to love the project and it has a sizeable, active fanbase. So how has a renewal not been announced yet?
