FWIW, I've seen her listed off/on on this site and another UK site, but never when I've been in London, so I've never inquired about her, and I've never used either service before, so I can't personally guarantee that they're on the up and up, but reports here and otherwise indicate that they are.  I'll be in London some time next year and hope to be able to see her.  Good luck to me and you .

If she's "early 20's," then she's had a rough life, like maybe she's been repairing broken slime lines in a salmon cannery or something like that.
