Winnie is Milly’s eight-year-old daughter. Brought along against Tony Last’s will on his and Milly’s weekend in Brighton, she threatens to derail the whole staged premise of an adulterous tryst. A relentless brat, her very vocal whining throughout the weekend makes Tony miserable at the time, but the unwanted attention it draws turns out to save him from Brenda’s extortion attempt by rendering the evidence of his “adultery” useless.
