So, what can fans expect from season three?

The third season follows on from season two's dramatic ending, which saw Ada Forte inherit a large sum of money following the death of her husband Rev. Forte, while Peggy Scott quit her dream job at the New York Globe and Marian Brook called off her engagement to Dashiell after realising her feelings for Larry.

While an official synopsis has yet to be released, creator and writer Julian said Marian and Larry's blossoming romance will result in more interactions between Marian's aunt Agnes and Larry's mother Bertha in season three.

"It might be quite nice to involve them in some situation that didn't depend on them liking each other but where they both had to turn up," he told TV Line . "I think that we might look for some dramatic situations that would provide that."
