Rose plots to bring a radio into the house; Sarah tutors Daisy; an art historian arrives; and Anna makes an embarrassing purchase on Mary's behalf.
Mary and Lord Gillingham's love is tested and Bates also faces a trial. In other events, Cora makes a new friend while Violet is reunited with an old one.
Lord Merton stuns Isobel; Mary has bad news for Tony; the police continue their investigation; and Robert and Sarah lock horns.
Rose makes a new acquaintance; Thomas appears ill; Edith's link to Marigold draws attention, and Robert and Bricker have a confrontation.
