Is FX Developing a Female 'Dexter'?

According to Deadline, FX is developing an adaptation of Chelsea Cain's trilogy of thrillers "Heartsick," "Sweetheart" and "Evil At Heart." The mystery series follows the disturbing relationship between a painkiller-addicted Portland detective named Archie Sheridan and the beautiful Gretchen Lowell, a therapist and serial killer who once captured and tortured Sheridan, only to let him go.

Will this be a gender-flipped answer to "Dexter"? Perhaps it's more a twist on "Silence of the Lambs" -- Gretchen is already behind bars at the beginning of Cain's best-selling first book, having turned herself in, and Archie compulsively visits her every week, hoping to find out why. Reviewing the novel in the New York Times, Kathryn Harrison noted that "Heartsick" is dark stuff indeed:

In Gretchen Lowell, Cain has created a femme fatale with an appetite for cruelty that will be difficult to surpass. Gretchen is hammering nails into Archie’s ribs when we meet her in the opening flashback; now she’s in jail entertaining weekly visits from him.

"5 Days Of War" writer Mikko Alanne will script the adaptation, which is being executive produced by Geyer Kosinski ("Magic City").
