Enid Blyton! And I did get them back, you just have to find the confiscated items building (an unmarked portocabin on a roundabout) and they happily hand them back. I think it's random, they just take a sample to check. If you ship though, don't send any delicate books, I think mine must have been left outside for a while, they were very dirty as if they had been on the ground out of the box.
