Niamh is the daughter of a high court judge. Not only that, she's gorgeous and bright. She's a pupil of Clive Reader.
However she feels that more is expected of her because of who her father is. She is in competition with Nick Slade for the tenancy in chambers and only one of them can get it. But at the same time they need to stick together, share their hopes and fears and support each other. This is tough when you are in competition with someone. Niamh is Clive's pupil.
The fate of her and Nick Slade hanged in the balance in the last episode of the first series, as it was left undecided as to who would join chambers was left undecided.
