Miss Pickering and the mystery of the free range eggs

This morning I opened up the shop as usual and discovered a box of M&S free range eggs. As much as I like nothing more than a nice plate of scrambled (preferably on a slice of sourdough and some of that butter with huge chunks of sea salt in it) they didn't belong to me. The hound also denied having purchased them, as he isn't really an egg eating kind of dog. I have kept them safe and await their rightful owner to claim them.
