I have just finished this book and I did think it was good but there’s one plot hole that’s really bugging me so I’m hoping I’ve just missed something.
At the end of the book it says that Savannah removes her bangle and throws it in the bin, just before she goes downstairs to answer her door for the last time.
So how does the bangle end up at Susan’s house? She finds it down the side of her husband’s bedside cabinet. This is a key plot point because it’s how Susan found out that her husband knew Savannah. However there’s no reference in the book to anybody finding the bangle in the bin at Savannah’s house and taking it to Susan’s house. Are we meant to just think that Jon went back to Savannah’s house at some point, found it (despite the fact that he wouldn’t have had a clue where it was) and inexplicably brought it home for his wife to find? Or did Greta take it and plant it in Susan’s house (which also doesn’t add up because Greta had no reason to know that the bangle even existed and wouldn’t have known it was in the bin).
I feel like I must be missing something obvious so hopefully someone else has the answer!
