Siobhan Finneran

Downton Abbey's fourth season, premiering on PBS in January, will say goodbye to Lady Cora's personal maid, O'Brien (Siobhan Finneran, who will appear in one episode to wrap up her story). O'Brien's exit will reverberate through the staff, affecting, among others, head housekeeper Mrs. Hughes (Phyllis Logan) and recently promoted cook's assistant Daisy (Sophie McShera).

"Daisy confronts Alfred, ­asking if he knew about his auntie and why he didn't tell everyone," McShera says. According to Logan, "Mrs. Hughes is tasked with the real headache of finding another lady's maid for Lady Cora. But someone interferes and ends up taking the decision out of Mrs. Hughes's hands, which is totally wrong. My toes get stepped on!"
