Rhoda Nunn - lesbian?

Rhoda Nunn amused me. Apart from being an out-an-out feminist, I can't help suspecting she is a lesbian. I wonder if she was one of the first portrayals of one in literature (1893). In the meeting between Virginia Madden and Rhoda Nunn in chapter 2 or 3, I was struck by Rhoda's manner of speech. It was sort of clipped and abrupt and rather to the point. In chapter 6, Rhoda Nunn has a bit of an argument with her boss, Miss Barfoot. They both want to help young women to become financially independent, but Rhoda is very hostile to marriage. Miss Barfoot asked her whether she had ever been in love with a man, and she replied once when she was fifteen.

Maybe not, she seems to be showing signs of attraction towards a certain Everard Barfoot. Still, she's a hard woman, harsh even.
