ITV's Downton Abbey 2011 Christmas special.
Set in 1919, Downton Abbey is hosting a lavish Christmas party, but Bates's arrest casts a shadow over the festivities.
Sharon Small played the part of Marigold Shore, the opinionated lady's maid to Lady Rosamund Painswick who visits Downton Abbey for Christmas, and who is later revealed to be having an affair with Lord Hepworth, Rosamund's suitor.
