This is possibly the hardest thing we have ever had to type.
We happened to be together this afternoon, when calls came from Mrs Overall's family letting both of us know that she sadly passed away a few days ago.
We have been asked not to release any further details yet (or to identify Mrs O in any way) in case other friends and/or family see this before being told in person.
This simple announcement is what Mrs O had asked each of us to do "if the worst happens".
We have lost a wonderful friend and are both sad beyond belief.
