The Last List of Mabel Beaumont

In early December, Mabel visits Reg Bishop to ask for help finding Dot. At his hot, impersonal bungalow, Reg recognizes Mabel’s given last name, says that he knew her brother, and agrees to search for Dot.

Back home, Mabel finds Julie, who shares that she and Martin have reconciled. Mabel borrows Kirsty’s phone under the pretense of planning a surprise party. She locates Kirsty’s mother’s number and invites her and her family to the party, lying when the mother asks if Kirsty wants them there. Later, Kirsty visits and asks to adopt Olly permanently. Mabel agrees but requests a few days to say goodbye.

Days later at Patty’s house, Mabel locates the phone number of Patty’s daughter, Sarah. Julie announces that Martin will be home for Christmas, and Patty offers her house for Kirsty’s birthday party. Later, Mabel sends an anonymous text to Sarah, warning her about her partner, Geoff (though she has no evidence to do so; Mabel’s only motivation is to cure Patty’s loneliness by bringing her daughter back to live with her again). An online search for Dorothy Brightmore brings no results.
