Melinda McGraw will play the "smart and ambitious" wife of Hollis Doyle (Gregg Henry) in ABC's "Scandal," TVLine reports.
McGraw, perhaps best known as Don Draper's mistress in "Mad Men" Season 2, will debut as Deborah in an April episode, and knowing what we know of husband Hollis -- the man responsible for rigging Fitz's (Tony Goldwyn) election -- we're guessing she's got her fair share of dirty laundry stashed away.
