Break out!

I wonder who it was that escaped from this tomb! It looked rather creepy with the sun just picking up the side, I could see there was some straw inside but the Hebridean in me said leave it alone! I once did a tour of a chambered cairn in Uist when one of the party , a German picked up a stone from the cairn and said he wanted to take it home. I said no! but he insisted.  I heard later that he posted the stone back to the Lodge nearby with the specific instructions to return it to the tomb! I wonder what bad luck befell him to make him post it back!
