More scheming from the ruthless Lydia

Following the success of the Masquerade party, which filled her Greek Street brothel’s empty coffers, madam Margaret Wells’ life and business begin to unravel this week. Her increasingly fed-up daughter Charlotte (Jessica Brown Findlay) decides to pack up and leave her ‘keeper’ Sir George Howard without a penny to her name. Meanwhile, Emily Lacey brings trouble to Margaret’s door when, beaten and bloodied by Lydia (Lesley Manville), she poisons Charles Quigley with laudanum and escapes the Golden Square brothel. But how long will it take before heartless Lydia finds her and has her hanged for attempted murder?
