I’m pretty sure I just read a vampire story by Tanith Lee that featured this vampire. (I’m pretty sure it wasn’t Angela Carter, because she’s dead.)
Except Tanith Lee had the vampire heiress fall in love with, and be vanquished by, a nice English soldier boy. And there was some very nice stuff with roses.
Of course it got very post-modern, because just telling a simple story is too un-ironic. But apparently Lee was also snarking at other segments of fandom and referencing this movie.
Anyway, that explains the name. But it’s driving me nuts that I can’t recall the story name.
