TNT has tapped one of the three female leads for Guilt by Association, The Hollywood Reporter said.

Two months after the cable network ordered a pilot based on the Marcia Clark novel, The Hollywood Reporter has learned that actress Elisabeth Rohm has signed on to star. A pickup would mark Rohm's first regular TV gig in a while, most recently recurring on Beauty and the Beast and Lifetime's The Client List.

Guilt by Association, based on a book by the same name, follows three women: a deputy district attorney, a LAPD detective and a female prosecutor -- each of whom end up embroiled in the same cases. Rohm joins as the tough detective.

Clark, who was famously served as lead prosecutor in the O.J. Simpson trial, co-wrote the pilot with Nashville's Dee Johnson.

A SAG winner for her recent work in American Hustle, Rohm's other TV Credits include Law & Order, Heroes and Angel.
