Apple from Eve, chapter 2

For some odd reason, Euphemia decides that when Tane comes to see the house, it must be spotless, and there can't be any sign that they need the money. One would think that renting out the family home would, in fact, give this impression, and that all the Sevres china and polished silver in the world wouldn't help, but Euphemia doesn't come to this conclusion. So we're treated to pages of Euphemia cleaning, polishing, and making a lovely tea for Tane.
Tane rents the house for a year, and throws a party. Euphemia is invited, and she meets thin, elegantly dressed Diana. Diana is the daughter of a baronet, and she is Tane's fiancee. She's also cold, and all too aware of her father's title. Euphemia has a rude little moment when she reminds Tane's housekeeper that, "Dr van Diederijk rents this house, Mrs Cross. I still own it" (p. 43).
The name of the book comes from an exchange between Tane and Euphemia. He sees her eating an apple, and says, "Eve and the apple" (p. 44). She asks whom she is tempting, and he assures her that she is not tempting him. That will turn out to be hogwash - but this is still a pointless title. Still, I suppose Betts couldn't name every book Marrying a Doctor.
By the way, I missed a tag in the last post: this is a older sister plot.
