Took all the cards down yesterday, checked for any who I had not sent to and vice versa, then put away safely .
This morning Postman Pat delivered another one. So what? you might conjecture. Well although properly addressed complete with post code there was no franking mark on the envelope by Royal Mail, or whoever it is these days. The stamp, 2nd class, suggests from Scotland as there is a picture annotated Edinburgh. Inside the card was no message or indication who had sent it.
I have very few contacts in Scotland but was able to check with the handwriting on a letter received last year, but I could find no significant similarities in the handwriting between the envelope and last year's letter.
Very puzzling. No doubt there may be some enlightenment in the future, but again it could remain a total mystery.
