Oh, Cess, darling, let me be the first to introduce you to Mrs. Parker! From reading your posts, I think you will like her (you need brains to appreciate Dot, and you certainly have those).
Rush out and get The Portable Dorothy Parker, which has a good many of her short stories, poems and book and play reviews. I personally can take or leave her poems (though some are clever) and her short stories range from brilliant to mawkish. But her reviews (which she herself brushed off) are priceless, just as funny and sharp as they were in the 1910s and '20s!
There are three bios of her; my favorite is the one by Marion Meade.Ignore the Jennifer Jason leigh film.
