do we know if Caroline had made a will - from Oliver's cluelessness about what to do with any of her things it sounds like she hadn't.
Earlier in the week, he said something to Shula about how they'd talked about death when they were making their wills together. I'd have thought her family background and business skills and so on - I think she'd have recognised the importance of a will. (Must update mine.) I don't think either she or Oliver would have been a total stranger to solicitors, and I don't think she was one for putting things off.
I shall miss Caroline/Sara's voice.
