I can't exactly say why but I think there's something very Under the Net and Iris Murdochy about Madame Arcati, even if the name is from Blithe Spirit and Noel Coward, and her tone is a little angrier. (No double Golden Globe winner playing Madame Arcati, methinks - not unless it's an "18"). Anyway, here's a flourish on the above:
I don't know why writers bother: why not just cut and paste other writers' cut-n-pastes and add a courtesy credit in brackets. It's as if the sheer gravitas of the subject cannot be appreciated without haystacking the auto-repeat adjectives and stories and pretending the piece is a self-contained first.
