mildred pierce book New novel from 'Mildred Pierce' author James M. Cain unearthedHBO’s adaptation of James M. Cain’s novel “Mildred Pierce” won two awards — for star Kate Winslet and best supporting actor Guy Pearce — at Sunday’s (Sept. 18) Emmy Awards and, as it turns out, HBO may soon have more material for a similar project.

A new novel by author Cain, who died in 1977, has been discovered and will be published in fall 2012 by imprint Hard Case Crime.

Cain — who also penned “The Postman Always Rings Twice” and “Double Indemnity” — had been rumored to be working on a book at the time of his death. Hard Case editor Charles Ardai says the manuscript for that book, “The Cocktail Waitress,” was unearthed by his literary agent in a box full of papers inherited from a colleague.

According to the New York Times, the book chronicles a young widowed cocktail waitress whose husband died under suspicious circumstances before she falls into a love triangle with a younger man and an older wealthy dude who, we expect, doesn’t make it to the end of the book.
