Harper Seven makes me think of a "divorced workaholic tough female boss" character from some US series about surgeons or lawyers or... She drinks too much to help her deal with the stress that such a high powered career causes, and of course she has a problematic relationship with her Mother who whines that she never gets in touch. There's an attractive (in a roguish way) male colleague in the picture who wants to get closer to her, but she's all wounded and defensive plus she's married to her job, so the foreplay can continue for three series.. I expect there's an ugly freckly little kid she spawned with the ex (a modern superdad in cords) and she never gets to his birthday party, bla bla..
