My high school math teacher disappeared when I was sixteen yearsd old. when I was in her class she would give us puzzles in code form. Many other collegues and I have recieved similiar letters written in code. I think that she is trying to give us a clue to where she, to see if we could find her. Obviously she isn't dead because she has written us these letters. My collegues and I think she is hiding somewhere for an important reason but no one knows why. We most likely will try to figure out where she is at and why. We hope she is ok. Wish us luck on this adventure!!
