Absolutely Fabulous: who was the real Patsy Stone?

When Lauretta Sullivan Feldman died in 2010, the few obituaries of her that were published described her as "the widow of Marty Feldman". What many missed is that Sullivan, the Bristol-born daughter of a butcher, was largely responsible for Feldman's success in America and ended her life as one of Los Angeles's most beloved and quietly influential cultural figures.

But did this impossibly glamorous woman also play a part in the creation of Absolutely Fabulous character Patsy Stone?
