When the Wells family is met by a baying mob outside their new home, Margaret fears she might be reaping the rewards of her public attack on Lydia Quigley.
As Lydia's campaign against her takes a toll on business, Margaret bets everything on an illicit masquerade, but will it make them or ruin them?
Lord Fallon shows interest in Lucy - can she finally snare herself a keeper? Charlotte's decision to leave Howard puts her in danger.
