Why aren't there more treasure hunt books where readers if they solve the puzzle(s) from the book can find actual real world treasure?
Never heard of this particular bit of publishing lore prior to this video.
What kind of treasure or reward do you think would be needed to entice readers of a new treasure hunt book to make it an actual national bestseller or even a global phenomenon?
It was very big over here when it came out. The writer had a piece on the BBC magazine show Nationwide and the book sold very well. My little brother got it for Christmas, we didn't have a clue where it was buried though. I understand it has been found, but not after many years.
