What happens in Season 4 of Miss Scarlet and the Duke?

In Season 4, Miss Scarlet takes over running Nash & Sons though things are not quite running as smoothly as she would like. Help comes from some familiar sources. Outside of work, her relationship with William “The Duke” Wellington builds towards a looming decision that will shape both their lives.

The show's creator, writer, and executive producer Rachael New teases, "I can tell you that Season 4 does set a few hairs running with both of those things. I don’t want to give too much away, but it does set Eliza on a different track, and it does bring home to Duke what he really does want."

Kate Phillips, who plays Miss Scarlet, hints at the Duke's relationship with her character, "There’s a little bit more about Eliza and William’s history, how they came to be. There’ll definitely be some more fun characters for you to meet that are really great and you’ll just love them. And more sparring and back and forth than ever!"

Felix Scott, who plays Nash on the series, talks about the dynamic between Nash and Miss Scarlett going into Season 4, "I think what you are going to see, particularly from Season 3 and into Season 4, is the development of the relationship between Eliza and Patrick in both friendship and a business sense. You’re going to see more action, more intrigue, more suspense, more detective work, and even more fun arguments between the two of them. Because frankly, that’s the pattern that they have between the two of them and the repertoire that really drives forward their friendship and their working relationship, as well."
