A couple return from holiday to find that their house has been stripped. Every single thing has been removed, right down to the telephone and the fitted carpets.
He sets out to get everything back and swindle as much as possible out of the insurance, eg by claiming for a much higher spec hi-fi. She realises that she feels liberated from the burden of having so much, though she misses the photo albums.
He has a stroke, and it seems to parallel their situations (him burdened, her freed).
Then she discovers the truth about the break-in. But I won't reveal the twist in the story, for fear of spoiling it in case anyone else wants to read it!
Anyone recognise?
