S1E4 · Episode 4

Berowne's daughter clearly has a secret that she has not shared with anyone except Ivor Garrett. Dalgliesh re-interviews Lady Berowne, Sir Paul's mother, and she lets it slip that he had a mistress. She is Carole Washburn who tells Dagliesh that Berowne had gone through a religious conversion. She refuses however to disclose anything else about their relationship other than they met at work and were always discreet. Dalgliesh visits the site where Diana Travers drowned and learns from the restaurant doorman, Henry, that Berowne was there the day of the drowning and was seen soaking wet. He also meets Millicent Gentle who, she says, was expecting him. Insp. Miskin meanwhile struggles with her own guilt over her grandmother who cannot live alone and who she wishes to put into a care home. —garykmcd
