Paper found inside other paper; paper exchanged for money
A book was donated to a shop. A year later, someone opened it. Inside was a different, more expensive piece of paper. The papers were sold together on eBay for £41,160 to a person who wishes to remain unnamed, and who is reportedly 'delighted', as buyers of paper often briefly are.
Media coverage has classified this as a 'hidden treasure' story, a genre that recurs on a roughly six-week cycle: painting in attic, coin in drawer, print in book. The treasure is always found by a volunteer, always 'fresh as the day it was made', always bought anonymously. You have read this story before. You will read it again, with a different noun.
To be fair — and we are condemned to fairness — the money goes to people in Norwich who need it, which is a genuinely acceptable outcome, as outcomes go.
The nation's remaining books will now be briefly shaken by their owners, yielding bookmarks, receipts, and one pressed flower. By Thursday the shelves will be still again. Nothing happened today. Correct.
