I love a Mystery!!!

I got my mail this morning and there was a little envelope - about the size of a credit card. I know it's from my niece - Stephanie - because it has her return address on it. Look what it says on the back.. Do not open until instructed. What could it be - a game? Oh, I'm soooo curious. I wonder if it's some sort of virtual Murder Mystery... thinking... thinking.... I feel like I'm in a James Bond movie. (We watched Casino Royal last night).....I'm quietly awaiting further instruction...
