Once again poor research on the part of the producers. Debt does not pass from father to son except on the decease of the former, and then only if the deceased's estate can support it.
Of far more interest to me was the lady having dinner with Audrey in the Bistro talking about the garden competition. "Bloody hell", I thought, "she looks just like my mother's old friend, Auntie Nell, from way back when". Made a point of pausing the credits to get a good look and, sure enough, it was Auntie Nell's daughter.
