Over at the Los Angeles Review of Books, the writer Kathleen Sharp has a fantastic piece on Millar's life and work. It is essential reading for Millar fanatics. (A reviewer once noted that "Millar doesn't attract fans; she creates addicts.") Sharp's essay is the single best thing I've read on Millar, and it makes me hope that she's working on a full length biography.
Read The Dangerous Housewife: Santa Barbara's Margaret Millar here.
PS. There is an error in Sharp's otherwise excellent piece that I should probably point out--I have feeling that other Millar fanatics will take me to task if I don't. She incorrectly describes THE IRON GATES as a gothic novel about abortion. It's neither a gothic novel nor is it about abortion.
