When John White let the group of colonist to Roanoke Island, they landed there, but after some time, they didn't have more food, or supplies. White decided that he was going back to England to get the supplies, but before leaving, he told to the colonist that went with him, that while he was gone they would be there without being able to communicate. They agreed that if they were in danger, they would leave a cross on a tree. White went to England, but when he was back to Roanoke for his surprise, there was no one, the only thing he found was a mark on a tree, but it wasn't a cross it was the word CROATAN, wrote on the tree. It is called a mistery because it was not of their knowledge if that word ment that they were attacked by coatans, or if it was where they went o what it meant.
