Sian Reese-Williams opened up about the challenges her character is facing when the series returns.
“Series two picks up around nine months after series one ends. We find Cadi trying to deal with the grief of losing her father, while trying to keep her head in her work,” she explained.
“It’s a difficult time for her – just as one begins to come through the initial shock of losing someone and start to try and deal with it, that’s the time that everyone around you starts to forget and move on. She’s also faced with dealing with the estranged daughter of the victim of the case, and the parallels she sees between the two of them are difficult for her to navigate professionally.”
