The story will revolve around a married woman Georgia who bequeaths her husband and kids to realize her sexual fantasies in LA.
"It's a very erotic mystery about...a woman and her secret desires that are, in fact, rather pure," the New York Post quoted Wilson as saying. She added: "She acts out in pretty extraordinary ways. It's all about an unfolding mystery."
"The language I write is often erotic, so there's no question (the HBO series) will be erotic -- even when there's no sex involved. There's nothing gratuitous. I would say in terms of creating eroticism that is integrated into the psychology of the lead character and the story, yes, there are similarities," she said.
"I think the woman's sexuality and sensuality in 'Secretary' -- both her fragility and her strength -- are central to Georgia's character (in the HBO series), as well. Georgia will embrace darkness with a joyful spirit."
The show will be a part of Winfrey's production deal with HBO.
