I got home to discover that some kind soul has changed the locks and put up a "for sale" notice. The estate agents tell me it's a reposession sale by the Royal Bank of Scotland.
WTF? I understood that the mortgage was paid by Anne's insurers when she died two years ago. I suspect some form of monunental cock-up.
And the paperwork is locked inside and would, in any case, take ages to find -- and I can't talk to anyone useful until tomorrow.
Edit (16:36): Bosses have given me a couple of days to sort it out. They're so patient.
