In season three of the hit series, Cassie begins to unravel due to the nature of the work she does for the police, particularly when their final suspect, Peter Finch, admits to the serial killing and sexual assault of countless women. His confession is particularly cold and heartless, as he was hiding the fact that he was a psychopath all along, and has a profound impact on Cassie, who takes three months of sick leave for her mental health.

Speaking about what to expect from her character in the upcoming episodes, Nicola told ITV: "When we meet her this series you realise she doesn’t really want to come back but she is in a terrible position that she will lose a massive amount of her pension payout on a technicality if she doesn’t come back and complete a certain number of months to comply with her pension.

"It is awful, she is in a complete trap so she agrees to come back so she can access the full amount of her pension because her dad is getting more and more ill and she is looking at the fact that she will probably be financially responsible for her father’s care. So she is completely caught. Her entire career she has very dedicatedly given to the police force. She is angry and feels very betrayed and that’s how she goes into this series’ story."
