It seems that the Wells girls can finally free themselves of their mother's feud, helped by allies such as Lady Fitz.

Meanwhile Lydia still finds a way to bite, even in her darkest hour.

Set against the backdrop of 18th century Georgian London, Harlots is a powerful family drama offering a brand new take on the city's most valuable commercial activity - sex.
