The series began airing on BBC One on 22 April 2018,[2] and stars Jessie Buckley, Ben Hardy, Olivia Vinall, Dougray Scott and Charles Dance.

[1] Walter Hartright receives a letter from Frederick Fairlie requesting that he restore his art collection and tutor his nieces at Limmeridge House in Cumberland.

Some time later Walter overhears a conversation between a policeman and a coach passenger suggesting that the woman is deranged and has escaped from an asylum.

Walter departs the next day for Limmeridge where he meets Frederick, his niece Laura, and her half-sister Marian Halcombe.

Marian tells Walter of Anne Catherick, a young lady no longer with them who dressed in white and bore a close resemblance to Laura.

Walter and Marian discuss their concerns with the solicitor Mr. Gilmore, who is unsympathetic, saying that Sir Percival is held in high regard but that he would speak to Glyde to clarify the situation.

As she listens to them from outside the house she is caught in the rain, leading her to contract a fever and the next day to be confined to bed.

Laura visits Marian, who tries in vain to tell her not to drink the tea that Fosco's wife is offering.

In the television production, the character Erasmus Nash (played by Art Malik) was added to achieve some of that condensation.
