The original cast members of Downton Abbey are truly dropping like flies, to the point that we might even miss the cruel and calculating Miss O’Brien—the latest to leave the show. Siobhan Finneran, who plays the scheming maid to Lady Grantham in the soapy period drama, announced that she’s departing Downton and will soon be seen on BBC One’s The Syndicate. “I’m not doing any more,” she said Friday. “O’Brien is a thoroughly despicable human being—that was great to play.” Despicable indeed, from her conniving antics with the closet-homosexual young under-butler, Thomas Barrow, to causing Lady Grantham to miscarry. How will the show go on without her?
