Series 3 of Downton Abbey looks like it’s going to be a good one. Will they be able to get Mr Bates off the death penalty? Will Lady Mary marry Matthew? Will the costumes be even more elaborate than last year? And has the Dowager Countess finally met her match in Lady Cora’s mother? Hollywood actress Shirley MacLaine will be playing American socialite Martha Levinson, the mother of the current Countess of Grantham, and I’m looking forward to hearing some snarky one-liners and watching the fur fly.
